The IMX296LLR is a monochrome 1.60MP CMOS sensor from Sony. The driver
supports cropping and binning (but not both at the same time due to
hardware limitations) and exposure, gain, vertical blanking and test
pattern controls.
Preliminary support is also included for the color IMX296LQR sensor.

Add support for the AYANEO AIR and AYANEO AIR Pro models of handheld
devices. These devices use the same EC registers and logic as the One X
Player mini AMD. Previous AYANEO models are not supported as they use a
different EC and do not have the necessary fan speed write enable and
setting registers. The driver is tested on AYANEO AIR while AIR Pro model
EC functionality and DMI data were verified using command line tools by
another user.
Add:
- AYANEO AIR (AMD 5560U)
- AYANEO AIR Pro (AMD 5560U)
- AYANEO AIR Pro (AMD 5825U)

The majority of bugfixes is once more for the NXP i.MX platform,
addressing issue with i.MX8M (UART, watchdog and ethernet) as well as
imx8dxl power button and the USB modem on an imx7 board. The reason that
i.MX always shows up here is obviously not that they are more buggy than
the others, but they have the most boards and are good about getting
fixes in quickly.
The other DT fixes are for the Nuvoton wpcm450 flash controller and
the i2c mux on an ASpeed board.
Lastly, there are updates to the MAINTAINERS entries for Mediatek,
AMD/Seattle and NXP SoCs, as well as a lone code fix for error
handling in the allwinner "rsb" bus driver.

In the work of Arnd's arm multi-platform support, various files in arch/arm
are moved and after the arm mach-pxa removal, only a few files remain to be
not aligned with entries in MAINTAINERS.
These file movements still require adjustments in MAINTAINERS:
Files in arch/arm/mach-ep93xx/include/mach/ are made local:
arch/arm/{mach-ep93xx/include/mach/uncompress.h => boot/compressed/misc-ep93xx.h}
arch/arm/mach-ep93xx/{include/mach => }/ep93xx-regs.h
arch/arm/mach-ep93xx/{include/mach => }/mach/irqs.h
Files in arch/arm/mach-vexpress/ are moved to mach-versatile.

Merge v6.2-rc6 into drm-next
Due to holidays we started -next with more -fixes in-flight than
usual, and people have been asking where they are. Backmerge to get
things better in sync.
Conflicts:
- Tiny conflict in drm_fbdev_generic.c between variable rename and
missing error handling that got added.
- Conflict in drm_fb_helper.c between the added call to vgaswitcheroo
in drm_fb_helper_single_fb_probe and a refactor patch that extracted
lots of helpers and incidentally removed the dev local variable.
Readd it to make things compile.

cc2520 supports both probing from static platform_data and
from devicetree, but there have never been any definitions
of the platform data in the mainline kernel, so it's safe
to assume that only the DT path is used.
After folding cc2520_platform_data into the driver itself,
the GPIO handling can be simplified by moving to the modern
gpiod interface.

Triple Modular Redundancy(TMR) subsystem contains three microblaze cores,
subsystem is fault-tolerant and continues to operate nominally after
encountering an error. Together with the capability to detect and recover
from errors, the implementation ensures the reliability of the entire
subsystem. TMR Manager is responsible for performing recovery of the
subsystem detects the fault via a break signal it invokes microblaze
software break handler which calls the tmr manager driver api to
update the error count and status, added support for fault detection
feature via sysfs interface.
Usage:
To know the break handler count(Error count):

The majority of all pxa board files has not been touched in a long time,

only support for the platforms that were already converted to DT, as
well as the gumstix and spitz/akita/borzoi machines that work in qemu
and can still be converted to DT later.

VPU stands for Versatile Processing Unit and it's a CPU-integrated
inference accelerator for Computer Vision and Deep Learning
applications.
The VPU device consist of following components:
- Buttress - provides CPU to VPU integration, interrupt, frequency and
power management.
- Memory Management Unit (based on ARM MMU-600) - translates VPU to
host DMA addresses, isolates user workloads.
- RISC based microcontroller - executes firmware that provides job
execution API for the kernel-mode driver
- Neural Compute Subsystem (NCS) - does the actual work, provides
Compute and Copy engines.
- Network on Chip (NoC) - network fabric connecting all the components
This driver supports VPU IP v2.7 integrated into Intel Meteor Lake
client CPUs (14th generation).
Module sources are at drivers/accel/ivpu and module name is
"intel_vpu.ko".
This patch includes only very besic functionality:
- module, PCI device and IRQ initialization
- register definitions and low level register manipulation functions
- SET/GET_PARAM ioctls
- power up without firmware

Now that we converted everything to just rely on struct mnt_idmap move it all
into a separate file. This ensure that no code can poke around in struct
mnt_idmap without any dedicated helpers and makes it easier to extend it in the
future. Filesystems will now not be able to conflate mount and filesystem
idmappings as they are two distinct types and require distinct helpers that
cannot be used interchangeably. We are now also able to extend struct mnt_idmap
as we see fit.

fscrypt.git is being renamed to linux.git, so update MAINTAINERS
accordingly. (The reasons for the rename are to match what I'm doing
for the new fsverity repo, which also involves the branch names changing
to be clearer; and to avoid ambiguity with userspace tools.)
As long as I'm updating the fscrypt MAINTAINERS entry anyway, also:
- Move my name to the top, so that people bother me first if they just
choose the first person. (In practice I'm the primary maintainer, and
Ted and Jaegeuk are backups.)
- Remove an unnecessary wildcard.

When the PTP is enabled in hardware bit 6 of PTP_MSG_CONF1 register, the
transmit frame needs additional 4 bytes before the tail tag. It is
needed for all the transmission packets irrespective of PTP packets or
not.
The 4-byte timestamp field is 0 for frames other than Pdelay_Resp. For
the one-step Pdelay_Resp, the switch needs the receive timestamp of the
Pdelay_Req message so that it can put the turnaround time in the
correction field.
Since PTP has to be enabled for both Transmission and reception
timestamping, driver needs to track of the tx and rx setting of the all
the user ports in the switch.
Two flags hw_tx_en and hw_rx_en are added in ksz_port to track the
timestampping setting of each port. When any one of ports has tx or rx
timestampping enabled, bit 6 of PTP_MSG_CONF1 is set and it is indicated
to tag_ksz.c through tagger bytes. This flag adds 4 additional bytes to
the tail tag. When tx and rx timestamping of all the ports are disabled,
then 4 bytes are not added.

Add EDAC support for Xilinx ZynqMP OCM Controller, so this driver reports CE and
UE errors upon interrupt generation. Also add debugfs files for error injection.
On Xilinx ZynqMP platform, both OCM Controller driver(zynqmp_edac) and DDR
Memory Controller driver(synopsys_edac) co-exist which means both can be loaded
at a time. This scenario is tested on Xilinx ZynqMP platform.

"The big change here is obviously the revert of the pktcdvd driver

- Re-instate the pktcdvd driver, which necessitates adding back

- Fix for splitting of a bio marked as NOWAIT, causing either nowait
reads or writes to error with EAGAIN even if parts of the IO
completed (me)
- Fix for ublk, punting management commands to io-wq as they can all
easily block for extended periods of time (Ming)

The devlink code is hard to navigate with 13kLoC in one file.
I really like the way Michal split the ethtool into per-command
files and core. It'd probably be too much to split it all up,
but we can at least separate the core parts out of the per-cmd
implementations and put it in a directory so that new commands
can be separate files.
Move the code, subsequent commit will do a partial split.

The TI LMP92064 is a dual 12 Bit ADC connected via SPI.
The two channels are intended for simultaneous measurements of the voltage
across- and current through a load to allow accurate instantaneous power
measurements.
The driver does not yet take advantage of this feature, as buffering is not
yet implemented.

This patch does following:
1. Adds a new cros-ec-uart driver. This driver can send EC requests on
UART and process response packets received on UART transport.
2. Once probed, this driver will initialize the serdev device based on
the underlying information in the ACPI resource. After serdev device
properties are set, this driver will register itself cros-ec.
3. High level driver can use this implementation to talk to ChromeOS
Embedded Controller device in case it supports UART as transport.
4. When cros-ec driver initiates a request packet, outgoing message is
processed in buffer and sent via serdev. Once bytes are sent, driver
enables a wait_queue.
5. Since ChromeOS EC device sends response asynchronously, AP's TTY
driver accumulates response bytes and calls the registered callback.
TTY driver can send multiple callback for bytes ranging from 1 to MAX
bytes supported by EC device.
6. Driver waits for EC_MSG_DEADLINE_MS to collect and process received
bytes. It wakes wait_queue if expected bytes are received or else
wait_queue timeout. Based on the error condition, driver returns
data_len or error to cros_ec.

The major goal of this PR is to update the kernel to upstream zstd v1.5.2 [0].
Specifically to the tag v1.5.2-kernel [1] which includes several cherrypicked
fixes for the kernel on top of v1.5.2.
Excepting the MAINTAINERS change, all the changes in this PR can be generated by:
```
git clone https://github.com/facebook/zstd
cd zstd/contrib/linux-kernel
git checkout v1.5.2-kernel
LINUX=/path/to/linux/repo make import
```
These changes have been baking in linux-next since 2022/10/24 when I put up
my patchset [2]. Notably the first commit is a small refactor of the only zstd
commit since the last update [3] to fit the upstream import scheme.
Additionally, this PR includes several minor typo fixes, which have all been
fixed upstream so they are maintained on the next import.

Libraries:
- Drop the old copy of libtraceevent in tools/lib/traceevent/ now that all major distros
ship it from its external repository.
This is now just another feature detection, emitting a warning when the
libtraceevent-dev[el] package isn't installed, disabling the build of perf features
and tools that strictly require parsing things from tracefs while keeping
the core functionality present and working with a subset of the events, the
most used ones like CPU cycles, hardware cache and also vendor events, etc.
This was tested with lots of containers for Fedora, Debian, OpenSUSE, Alpine Linux,
Ubuntu, with cross builds, etc.
Build:
- Update to C standard to gnu11, like was done for the kernel.
- Install the tools/lib/ libraries locally instead of having headers searched
directly from the source code directories, to help the cases where we can
build either from in-kernel source libraries or from the same library shipped
as a distro package, as is the case with libbpf and was the case with
libtraceevent.
perf stat:
- Do not delay the workload with --delay, the delay is just for starting to count
the events, to skip noise at workload startup.
- When we have events for each cgroup, the metric should be printed for each
cgroup separately.
$ perf stat -a --for-each-cgroup system.slice,user.slice --metric-only sleep 1
Performance counter stats for 'system wide':
GHz insn per cycle branch-misses of all branches
system.slice 3.792 0.61 3.24%
user.slice 3.661 2.32 0.37%
- Fix printing field separator in CSV metrics output.
- Fix --metric-only --json output.
- Fix summary output in CSV with --metric-only.
- Update event group check for support of uncore event.
perf test:
- Stop requiring a C toolchain in shell tests, instead add a workload option that has
all the previously C snippets built as part of 'perf test -w' that then get used in
the 'perf test' shell scripts.
- Add event group test for events in multiple PMUs
- The "kernel lock contention analysis" test should not print warnings in quiet mode.
- Add attr tests for ARM64's new VG register.
- Fix record test on KVM guests, as using precise flag with the
br_inst_retired.near_call event causes the test fail on KVM guests, even when
the guests have PMU forwarding enabled and the event itself is supported, so just
remove the precise flag from the event.
- Add mechanism for skipping attr tests on specific kernel versions where it is known that
these checks will fail.
- Skip watchpoint tests if no watchpoints available.
- Add more Intel PT 'perf test' entries: hybrid CPUs, split the packet decoder
into a suite of subtests.
perf script:
- Introduce task analyzer python script, where one first records some events:
Recording can be done in two ways:
$ perf script record tasks-analyzer -- sleep 10
$ perf record -e sched:sched_switch -a -- sleep 10
The script can parse any perf.data files, as long as it has sched:sched_switch events,
other events will be ignored.
The most simple report use case is to just call the script without arguments.
Runtime is the time the task was running on the CPU, Time Out-In is the time
between the process being scheduled *out* and scheduled back *in*. So the last
time span between two executions:
$ perf script report tasks-analyzer
Switched-In Switched-Out CPU PID TID Comm Runtime Time Out-In

perf lock:

perf record:
- Add remaining branch filters: "no_cycles", "no_flags" & "hw_index", to be
used with hardware such as Intel's LBR that allows things like stitching
stacks of two samples to overcome the limits of the number of LBR registers.
Symbol resolution:
- Handle .debug files created with 'objcopy --only-keep-debug', where program
headers are zeroed and thus can't be used for adjustments, use the info in
the runtime_ss (runtime ELF) instead.
perf trace:
- Add BPF based augmenter for the 'perf_event_open's 'struct perf_event_attr' argument.
- Add BPF based augmenter for the 'clock_gettime's 'struct timespec' argument.
- In both cases the syscall tracepoint has just the pointer value, we
need to hook a BPF program to collect the pointer contents, and then,
in userspace, pretty print it in 'perf trace'.
perf list:
- Introduce JSON output of events.
- Streamline how the expression specifying what events should be shown is handled,
fixing several corner cases, such as the metric filter that is specified as a glob
but was using strstr().
perf probe:
- Fix to avoid crashing if DW_AT_decl_file is NULL, coping with clang generating
DWARF5 like that.
- Use dwarf_attr_integrate() as generic DWARF attr accessor as it supersedes dwarf_attr(),
supporting abstact origin DIEs.
perf inject:
- Set PERF_RECORD_MISC_BUILD_ID_SIZE in the PERF_RECORD_HEADER_BUILD_ID so that
perf.data readers can get the real build-id size and avoid trailing zeros.
perf data:
- Add tracepoint fields when converting a perf.data file to JSON.
arm64:
- Fix mksyscalltbl, don't lose syscalls due to sort -nu.
- Add Arm Neoverse V2 PMU events.
riscv:
- Add riscv sbi firmware std event files.
- Add Sifive U74 vendor events (JSON) file.
- Add some more events and metrics for Alderlake/Alderlake-N.
Documentation:
- Add data documentation for the PMU structs in the C source code.
Miscellaneous:
- Periodic sanitization of headers, adding missing includes, removing needless ones,
creating new ones, etc.
- Use sig_atomic_t for signal handlers to avoid undefined behaviour in all perf
tools.
- Fixes for libbpf 1.0+ compatibility (maps, etc) on 'perf trace' BPF examples.
- Remove some old perf bpf examples, leave the best ones that demonstrate how
to associate BPF functions to points in the kernel.
- Make quiet mode consistent between tools.
- Use dedicated non-atomic clear/set bit helpers.
- Use "grep -E" instead of "egrep" as recommended by warning emitted by GNU
grep since at least version 3.8.
- Complete list of supported subcommands in the 'perf daemon' help message.
- Update John Garry's email address for arm64 perf tooling on the MAINTAINERS file,
he moved from Huawei to Oracle.

Here is the large set of char/misc and other driver subsystem changes
for 6.2-rc1. Nothing earth-shattering in here at all, just a lot of new
driver development and minor fixes. Highlights include:
- fastrpc driver updates
- iio new drivers and updates
- habanalabs driver updates for new hardware and features
- slimbus driver updates
- speakup module parameters added to aid in boot time configuration
- i2c probe_new conversions for lots of different drivers
- other small driver fixes and additions
One semi-interesting change in here is the increase of the number of
misc dynamic minors available to 1048448 to handle new huge-cpu systems.
All of these have been in linux-next for a while with no reported
problems.

Here is the large set of USB and Thunderbolt driver changes for 6.2-rc1.
Overall, thanks to the removal of a driver, more lines were removed than
added, a nice change. Highlights include:
- removal of the sisusbvga driver that was not used by anyone anymore
- minor thunderbolt driver changes and tweaks
- chipidea driver updates
- usual set of typec driver features and hardware support added
- musb minor driver fixes
- fotg210 driver fixes, bringing that hardware back from the "dead"
- minor dwc3 driver updates
- addition, and then removal, of a list.h helper function for many USB
and other subsystem drivers, that ended up breaking the build. That
will come back for 6.3-rc1, it missed this merge window.
- usual xhci updates and enhancements
- usb-serial driver updates and support for new devices
- other minor USB driver updates
All of these have been in linux-next for a while with no reported

* Enable the per-vcpu dirty-ring tracking mechanism, together with an
option to keep the good old dirty log around for pages that are
dirtied by something other than a vcpu.
* Switch to the relaxed parallel fault handling, using RCU to delay
page table reclaim and giving better performance under load.
* Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping option,
which multi-process VMMs such as crosvm rely on (see merge commit 382b5b87a9:
"Fix a number of issues with MTE, such as races on the tags being
initialised vs the PG_mte_tagged flag as well as the lack of support
for VM_SHARED when KVM is involved. Patches from Catalin Marinas and
Peter Collingbourne").
* Merge the pKVM shadow vcpu state tracking that allows the hypervisor
to have its own view of a vcpu, keeping that state private.
* Add support for the PMUv3p5 architecture revision, bringing support
for 64bit counters on systems that support it, and fix the
no-quite-compliant CHAIN-ed counter support for the machines that
actually exist out there.
* Fix a handful of minor issues around 52bit VA/PA support (64kB pages
only) as a prefix of the oncoming support for 4kB and 16kB pages.
* Pick a small set of documentation and spelling fixes, because no
good merge window would be complete without those.
s390:
* Second batch of the lazy destroy patches
* First batch of KVM changes for kernel virtual != physical address support
* Removal of a unused function
x86:
* Allow compiling out SMM support
* Cleanup and documentation of SMM state save area format
* Preserve interrupt shadow in SMM state save area
* Respond to generic signals during slow page faults
* Fixes and optimizations for the non-executable huge page errata fix.
* Reprogram all performance counters on PMU filter change
* Cleanups to Hyper-V emulation and tests
* Process Hyper-V TLB flushes from a nested guest (i.e. from a L2 guest
running on top of a L1 Hyper-V hypervisor)
* Advertise several new Intel features
* x86 Xen-for-KVM:
** Allow the Xen runstate information to cross a page boundary
** Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured
** Add support for 32-bit guests in SCHEDOP_poll
* Notable x86 fixes and cleanups:
** One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0).
** Reinstate IBPB on emulated VM-Exit that was incorrectly dropped a few
years back when eliminating unnecessary barriers when switching between
vmcs01 and vmcs02.
** Clean up vmread_error_trampoline() to make it more obvious that params
must be passed on the stack, even for x86-64.
** Let userspace set all supported bits in MSR_IA32_FEAT_CTL irrespective
of the current guest CPUID.
** Fudge around a race with TSC refinement that results in KVM incorrectly
thinking a guest needs TSC scaling when running on a CPU with a
constant TSC, but no hardware-enumerated TSC frequency.
** Advertise (on AMD) that the SMM_CTL MSR is not supported
** Remove unnecessary exports
Generic:
* Support for responding to signals during page faults; introduces
new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks
Selftests:
* Fix an inverted check in the access tracking perf test, and restore
support for asserting that there aren't too many idle pages when
running on bare metal.
* Fix build errors that occur in certain setups (unsure exactly what is
unique about the problematic setup) due to glibc overriding
static_assert() to a variant that requires a custom message.
* Introduce actual atomics for clear/set_bit() in selftests
* Add support for pinning vCPUs in dirty_log_perf_test.
* Rename the so called "perf_util" framework to "memstress".
* Add a lightweight psuedo RNG for guest use, and use it to randomize
the access pattern and write vs. read percentage in the memstress tests.
* Add a common ucall implementation; code dedup and pre-work for running
SEV (and beyond) guests in selftests.
* Provide a common constructor and arch hook, which will eventually be
used by x86 to automatically select the right hypercall (AMD vs. Intel).
* A bunch of added/enabled/fixed selftests for ARM64, covering memslots,
breakpoints, stage-2 faults and access tracking.
* x86-specific selftest changes:
** Clean up x86's page table management.
** Clean up and enhance the "smaller maxphyaddr" test, and add a related
test to cover generic emulation failure.
** Clean up the nEPT support checks.
** Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.
** Fix an ordering issue in the AMX test introduced by recent conversions

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm
Pull kvm updates from Paolo Bonzini:
"ARM64:
- Enable the per-vcpu dirty-ring tracking mechanism, together with an
option to keep the good old dirty log around for pages that are
dirtied by something other than a vcpu.
- Switch to the relaxed parallel fault handling, using RCU to delay
page table reclaim and giving better performance under load.
- Relax the MTE ABI, allowing a VMM to use the MAP_SHARED mapping
option, which multi-process VMMs such as crosvm rely on (see merge
commit 382b5b87a9: "Fix a number of issues with MTE, such as
races on the tags being initialised vs the PG_mte_tagged flag as
well as the lack of support for VM_SHARED when KVM is involved.
Patches from Catalin Marinas and Peter Collingbourne").
- Merge the pKVM shadow vcpu state tracking that allows the
hypervisor to have its own view of a vcpu, keeping that state
private.
- Add support for the PMUv3p5 architecture revision, bringing support
for 64bit counters on systems that support it, and fix the
no-quite-compliant CHAIN-ed counter support for the machines that
actually exist out there.
- Fix a handful of minor issues around 52bit VA/PA support (64kB
pages only) as a prefix of the oncoming support for 4kB and 16kB
pages.
- Pick a small set of documentation and spelling fixes, because no
good merge window would be complete without those.
s390:
- Second batch of the lazy destroy patches
- First batch of KVM changes for kernel virtual != physical address
support
- Removal of a unused function
x86:
- Allow compiling out SMM support
- Cleanup and documentation of SMM state save area format
- Preserve interrupt shadow in SMM state save area
- Respond to generic signals during slow page faults
- Fixes and optimizations for the non-executable huge page errata
fix.
- Reprogram all performance counters on PMU filter change
- Cleanups to Hyper-V emulation and tests
- Process Hyper-V TLB flushes from a nested guest (i.e. from a L2
guest running on top of a L1 Hyper-V hypervisor)
- Advertise several new Intel features
- x86 Xen-for-KVM:
- Allow the Xen runstate information to cross a page boundary
- Allow XEN_RUNSTATE_UPDATE flag behaviour to be configured
- Add support for 32-bit guests in SCHEDOP_poll
- Notable x86 fixes and cleanups:
- One-off fixes for various emulation flows (SGX, VMXON, NRIPS=0).
- Reinstate IBPB on emulated VM-Exit that was incorrectly dropped
a few years back when eliminating unnecessary barriers when
switching between vmcs01 and vmcs02.
- Clean up vmread_error_trampoline() to make it more obvious that
params must be passed on the stack, even for x86-64.
- Let userspace set all supported bits in MSR_IA32_FEAT_CTL
irrespective of the current guest CPUID.
- Fudge around a race with TSC refinement that results in KVM
incorrectly thinking a guest needs TSC scaling when running on a
CPU with a constant TSC, but no hardware-enumerated TSC
frequency.
- Advertise (on AMD) that the SMM_CTL MSR is not supported
- Remove unnecessary exports
Generic:
- Support for responding to signals during page faults; introduces
new FOLL_INTERRUPTIBLE flag that was reviewed by mm folks
Selftests:
- Fix an inverted check in the access tracking perf test, and restore
support for asserting that there aren't too many idle pages when
running on bare metal.
- Fix build errors that occur in certain setups (unsure exactly what
is unique about the problematic setup) due to glibc overriding
static_assert() to a variant that requires a custom message.
- Introduce actual atomics for clear/set_bit() in selftests
- Add support for pinning vCPUs in dirty_log_perf_test.
- Rename the so called "perf_util" framework to "memstress".
- Add a lightweight psuedo RNG for guest use, and use it to randomize
the access pattern and write vs. read percentage in the memstress
tests.
- Add a common ucall implementation; code dedup and pre-work for
running SEV (and beyond) guests in selftests.
- Provide a common constructor and arch hook, which will eventually
be used by x86 to automatically select the right hypercall (AMD vs.
Intel).
- A bunch of added/enabled/fixed selftests for ARM64, covering
memslots, breakpoints, stage-2 faults and access tracking.
- x86-specific selftest changes:
- Clean up x86's page table management.
- Clean up and enhance the "smaller maxphyaddr" test, and add a
related test to cover generic emulation failure.
- Clean up the nEPT support checks.
- Add X86_PROPERTY_* framework to retrieve multi-bit CPUID values.
- Fix an ordering issue in the AMX test introduced by recent
conversions to use kvm_cpu_has(), and harden the code to guard
against similar bugs in the future. Anything that tiggers
caching of KVM's supported CPUID, kvm_cpu_has() in this case,
effectively hides opt-in XSAVE features if the caching occurs
