Such MEMBLOCK_NOMAP regions should not be saved during hibernation. This problem was introduced by changes to the pfn_valid() logic in commit |

arm64/head: Disable MMU at EL2 before clearing HCR_EL2.E2H
Even though the boot protocol stipulates otherwise, an exception has
been made for the EFI stub, and entering the core kernel with the MMU
enabled is permitted. This allows a substantial amount of cache
maintenance to be elided, wich is significant when fast boot times are
critical (e.g., for booting micro-VMs)
Once the initial ID map has been populated, the MMU is disabled as part
of the logic sequence that puts all system registers into a known state.
Any code that needs to execute within the window where the MMU is off is
cleaned to the PoC explicitly, which includes all of HYP text when
entering at EL2.
However, the current sequence of initializing the EL2 system registers
is not safe: HCR_EL2 is set to its nVHE initial state before SCTLR_EL2
is reprogrammed, and this means that a VHE-to-nVHE switch may occur
while the MMU is enabled. This switch causes some system registers as
well as page table descriptors to be interpreted in a different way,
potentially resulting in spurious exceptions relating to MMU
translation.
So disable the MMU explicitly first when entering in EL2 with the MMU
and caches enabled.

arm64/head: Drop unnecessary pre-disable-MMU workaround
The Falkor erratum that results in the need for an ISB before clearing the M bit in SCTLR_ELx only applies to execution at exception level x, and so the workaround is not needed when disabling the EL1 MMU while running at EL2.

arm64/hugetlb: Fix page table walk in huge_pte_alloc()
Currently normal HugeTLB fault ends up crashing the kernel, as p4dp derived
from p4d_offset() is an invalid address when PGTABLE_LEVEL = 5. A p4d level
entry needs to be allocated when not available while walking the page table
during HugeTLB faults. Let's call p4d_alloc() to allocate such entries when
required instead of current p4d_offset().

arm64/ptrace: Use saved floating point state type to determine SVE layout
The SVE register sets have two different formats, one of which is a wrapped
version of the standard FPSIMD register set and another with actual SVE
register data. At present we check TIF_SVE to see if full SVE register
state should be provided when reading the SVE regset but if we were in a
syscall we may have saved only floating point registers even though that is
set.
Fix this and simplify the logic by checking and using the format which we
recorded when deciding if we should use FPSIMD or SVE format.

Arg0 is divided by 4 in lpcg driver, so index 0 and 1 will be get by pwm

work, but code logic is wrong. Fixed it by use correct indices.

arm64: dts: imx8-ss-conn: fix usdhc wrong lpcg clock order
The actual clock show wrong frequency:
echo on >/sys/devices/platform/bus\@5b000000/5b010000.mmc/power/control
cat /sys/kernel/debug/mmc0/ios
clock: 200000000 Hz
actual clock: 166000000 Hz
^^^^^^^^^
.....
According to
sdhc0_lpcg: clock-controller@5b200000 {
compatible = "fsl,imx8qxp-lpcg";
reg = <0x5b200000 0x10000>;
#clock-cells = <1>;
clocks = <&clk IMX_SC_R_SDHC_0 IMX_SC_PM_CLK_PER>,
<&conn_ipg_clk>, <&conn_axi_clk>;
clock-indices = <IMX_LPCG_CLK_0>, <IMX_LPCG_CLK_4>,
<IMX_LPCG_CLK_5>;
clock-output-names = "sdhc0_lpcg_per_clk",
"sdhc0_lpcg_ipg_clk",
"sdhc0_lpcg_ahb_clk";
power-domains = <&pd IMX_SC_R_SDHC_0>;
}
"per_clk" should be IMX_LPCG_CLK_0 instead of IMX_LPCG_CLK_5.
After correct clocks order:
echo on >/sys/devices/platform/bus\@5b000000/5b010000.mmc/power/control
cat /sys/kernel/debug/mmc0/ios
clock: 200000000 Hz

KVM: arm64: Rationalise KVM banner output
We are not very consistent when it comes to displaying which mode
we're in (VHE, {n,h}VHE, protected or not). For example, booting
in protected mode with hVHE results in:
[ 0.969545] kvm [1]: Protected nVHE mode initialized successfully
which is mildly amusing considering that the machine is VHE only.
We already cleaned this up a bit with commit

KVM: arm64: Ensure target address is granule-aligned for range TLBI
When zapping a table entry in stage2_try_break_pte(), we issue range
TLB invalidation for the region that was mapped by the table. However,
we neglect to align the base address down to the granule size and so
if we ended up reaching the table entry via a misaligned address then
we will accidentally skip invalidation for some prefix of the affected
address range.
Align 'ctx->addr' down to the granule size when performing TLB
invalidation for an unmapped table in stage2_try_break_pte().

arm64: dts: qcom: sc7180-trogdor: mark bluetooth address as broken
Several Qualcomm Bluetooth controllers lack persistent storage for the
device address and instead one can be provided by the boot firmware
using the 'local-bd-address' devicetree property.
The Bluetooth bindings clearly states that the address should be
specified in little-endian order, but due to a long-standing bug in the
Qualcomm driver which reversed the address some boot firmware has been
providing the address in big-endian order instead.
The boot firmware in SC7180 Trogdor Chromebooks is known to be affected
so mark the 'local-bd-address' property as broken to maintain backwards
compatibility with older firmware when fixing the underlying driver bug.
Note that ChromeOS always updates the kernel and devicetree in lockstep
so that there is no need to handle backwards compatibility with older
devicetrees.

When using usb-conn-gpio to control USB role and VBUS, the vbus-supply
property must be present in the usb-conn-gpio node. Additionally it
should not be present in the phy node as that isn't what controls vbus
and will upset the use count.
This resolves an issue where VBUS is enabled with OTG in peripheral

bpf, arm64: fix bug in BPF_LDX_MEMSX
A64_LDRSW() takes three registers: Xt, Xn, Xm as arguments and it loads
and sign extends the value at address Xn + Xm into register Xt.
Currently, the offset is being directly used in place of the tmp
register which has the offset already loaded by the last emitted
instruction.
This will cause JIT failures. The easiest way to reproduce this is to
test the following code through test_bpf module:
{
"BPF_LDX_MEMSX | BPF_W",
.u.insns_int = {
BPF_LD_IMM64(R1, 0x00000000deadbeefULL),
BPF_LD_IMM64(R2, 0xffffffffdeadbeefULL),

We need to use the offset as -7 to trigger this code path, there could
be other valid ways to trigger this from proper BPF programs as well.
This code is rejected by the JIT because -7 is passed to A64_LDRSW() but
it expects a valid register (0 - 31).

x86/hyperv: Use Hyper-V entropy to seed guest random number generator
A Hyper-V host provides its guest VMs with entropy in a custom ACPI table named "OEM0". The entropy bits are updated each time Hyper-V boots the VM, and are suitable for seeding the Linux guest random number generator (rng). See a brief description of OEM0 in [1]. Generation 2 VMs on Hyper-V use UEFI to boot. Existing EFI code in Linux seeds the rng with entropy bits from the EFI_RNG_PROTOCOL. Via this path, the rng is seeded very early during boot with good entropy. The ACPI OEM0 table provided in such VMs is an additional source of entropy. Generation 1 VMs on Hyper-V boot from BIOS. For these VMs, Linux doesn't currently get any entropy from the Hyper-V host. While this is not fundamentally broken because Linux can generate its own entropy, using the Hyper-V host provided entropy would get the rng off to a better start and would do so earlier in the boot process. Improve the rng seeding for Generation 1 VMs by having Hyper-V specific code in Linux take advantage of the OEM0 table to seed the rng. For Generation 2 VMs, use the OEM0 table to provide additional entropy beyond the EFI_RNG_PROTOCOL. Because the OEM0 table is custom to Hyper-V, parse it directly in the Hyper-V code in the Linux kernel and use add_bootloader_randomness() to add it to the rng. Once the entropy bits are read from OEM0, zero them out in the table so they don't appear in /sys/firmware/acpi/tables/OEM0 in the running VM. The zero'ing is done out of an abundance of caution to avoid potential security risks to the rng. Also set the OEM0 data length to zero so a kexec or other subsequent use of the table won't try to use the zero'ed bits.

ARM64: Dynamically allocate cpumasks and increase supported CPUs to 512
[ a.k.a. Revert "Revert "ARM64: Dynamically allocate cpumasks and
increase supported CPUs to 512""; originally reverted because of a
bug in the cpufreq-dt code not using zalloc_cpumask_var() ]
Currently defconfig selects NR_CPUS=256, but some vendors (e.g. Ampere
Computing) are planning to ship systems with 512 CPUs. So that all CPUs on
these systems can be used with defconfig, we'd like to bump NR_CPUS to 512.
Therefore this patch increases the default NR_CPUS from 256 to 512.
As increasing NR_CPUS will increase the size of cpumasks, there's a fear that
this might have a significant impact on stack usage due to code which places
cpumasks on the stack. To mitigate that concern, we can select
CPUMASK_OFFSTACK. As that doesn't seem to be a problem today with
NR_CPUS=256, we only select this when NR_CPUS > 256.
CPUMASK_OFFSTACK configures the cpumasks in the kernel to be
dynamically allocated. This was used in the X86 architecture in the
past to enable support for larger CPU configurations up to 8k cpus.
With that is becomes possible to dynamically size the allocation of
the cpu bitmaps depending on the quantity of processors detected on
bootup. Memory used for cpumasks will increase if the kernel is
run on a machine with more cores.
Further increases may be needed if ARM processor vendors start
supporting more processors. Given the current inflationary trends
in core counts from multiple processor manufacturers this may occur.
There are minor regressions for hackbench. The kernel data size
for 512 cpus is smaller with offstack than with onstack.
Benchmark results using hackbench average over 10 runs of
hackbench -s 512 -l 2000 -g 15 -f 25 -P

hyperv-tlfs: Rename some HV_REGISTER_* defines for consistency
Rename HV_REGISTER_GUEST_OSID to HV_REGISTER_GUEST_OS_ID. This matches the existing HV_X64_MSR_GUEST_OS_ID. Rename HV_REGISTER_CRASH_* to HV_REGISTER_GUEST_CRASH_*. Including GUEST_ is consistent with other #defines such as HV_FEATURE_GUEST_CRASH_MSR_AVAILABLE. The new names also match the TLFS document more accurately, i.e. HvRegisterGuestCrash*.

* Changes to FPU handling came in via the main s390 pull request * Only deliver to the guest the SCLP events that userspace has requested. * More virtual vs physical address fixes (only a cleanup since virtual and physical address spaces are currently the same). * Fix selftests undefined behavior. x86: * Fix a restriction that the guest can't program a PMU event whose encoding matches an architectural event that isn't included in the guest CPUID. The enumeration of an architectural event only says that if a CPU supports an architectural event, then the event can be programmed *using the architectural encoding*. The enumeration does NOT say anything about the encoding when the CPU doesn't report support the event *in general*. It might support it, and it might support it using the same encoding that made it into the architectural PMU spec. * Fix a variety of bugs in KVM's emulation of RDPMC (more details on individual commits) and add a selftest to verify KVM correctly emulates RDMPC, counter availability, and a variety of other PMC-related behaviors that depend on guest CPUID and therefore are easier to validate with selftests than with custom guests (aka kvm-unit-tests). * Zero out PMU state on AMD if the virtual PMU is disabled, it does not cause any bug but it wastes time in various cases where KVM would check if a PMC event needs to be synthesized. * Optimize triggering of emulated events, with a nice ~10% performance improvement in VM-Exit microbenchmarks when a vPMU is exposed to the guest. * Tighten the check for "PMI in guest" to reduce false positives if an NMI arrives in the host while KVM is handling an IRQ VM-Exit. * Fix a bug where KVM would report stale/bogus exit qualification information when exiting to userspace with an internal error exit code. * Add a VMX flag in /proc/cpuinfo to report 5-level EPT support. * Rework TDP MMU root unload, free, and alloc to run with mmu_lock held for read, e.g. to avoid serializing vCPUs when userspace deletes a memslot. * Tear down TDP MMU page tables at 4KiB granularity (used to be 1GiB). KVM doesn't support yielding in the middle of processing a zap, and 1GiB granularity resulted in multi-millisecond lags that are quite impolite for CONFIG_PREEMPT kernels. * Allocate write-tracking metadata on-demand to avoid the memory overhead when a kernel is built with i915 virtualization support but the workloads use neither shadow paging nor i915 virtualization. * Explicitly initialize a variety of on-stack variables in the emulator that triggered KMSAN false positives. * Fix the debugregs ABI for 32-bit KVM. * Rework the "force immediate exit" code so that vendor code ultimately decides how and when to force the exit, which allowed some optimization for both Intel and AMD. * Fix a long-standing bug where kvm_has_noapic_vcpu could be left elevated if vCPU creation ultimately failed, causing extra unnecessary work. * Cleanup the logic for checking if the currently loaded vCPU is in-kernel. * Harden against underflowing the active mmu_notifier invalidation count, so that "bad" invalidations (usually due to bugs elsehwere in the kernel) are detected earlier and are less likely to hang the kernel. x86 Xen emulation: * Overlay pages can now be cached based on host virtual address, instead of guest physical addresses. This removes the need to reconfigure and invalidate the cache if the guest changes the gpa but the underlying host virtual address remains the same. * When possible, use a single host TSC value when computing the deadline for Xen timers in order to improve the accuracy of the timer emulation. * Inject pending upcall events when the vCPU software-enables its APIC to fix a bug where an upcall can be lost (and to follow Xen's behavior). * Fall back to the slow path instead of warning if "fast" IRQ delivery of Xen events fails, e.g. if the guest has aliased xAPIC IDs.

Generic: * cleanup Kconfig by removing CONFIG_HAVE_KVM, which was basically always true on all architectures except MIPS (where Kconfig determines the available depending on CPU capabilities). It is replaced either by an architecture-dependent symbol for MIPS, and IS_ENABLED(CONFIG_KVM) everywhere else. * Factor common "select" statements in common code instead of requiring each architecture to specify it * Remove thoroughly obsolete APIs from the uapi headers. * Move architecture-dependent stuff to uapi/asm/kvm.h * Always flush the async page fault workqueue when a work item is being removed, especially during vCPU destruction, to ensure that there are no workers running in KVM code when all references to KVM-the-module are gone, i.e. to prevent a very unlikely use-after-free if kvm.ko is unloaded. * Grab a reference to the VM's mm_struct in the async #PF worker itself instead of gifting the worker a reference, so that there's no need to remember to *conditionally* clean up after the worker.

MTD
The Carillo Ranch driver has been removed. Top level mtd bindings have received a couple of improvements (references, selects). The ssfdc driver received few minor adjustments. These changes come with the usual load of misc/small improvements and fixes. Raw NAND The main series brought is an update of the Broadcom support to support all BCMBCA SoCs and their specificity (ECC, write protection, configuration straps), plus a few misc fixes and changes in the main driver. Device tree updates are also part of this PR, initially because of a misunderstanding on my side. The STM32_FMC2 controller driver is also upgraded to properly support MP1 and MP25 SoCs. A new compatible is added for an Atmel flavor. Among all these feature changes, there is as well a load of continuous read related fixes, avoiding more corner conditions and clarifying the logic. Finally a few miscellaneous fixes are made to the core, the lpx32xx_mlc, fsl_lbc, Meson and Atmel controller driver, as well as final one in the Hynix vendor driver. SPI-NAND The ESMT support has been extended to match 5 bytes ID to avoid collisions. Winbond support on its side receives support for W25N04KV chips. SPI NOR SPI NOR gets the non uniform erase code cleaned. We stopped using bitmasks for erase types and flags, and instead introduced dedicated members. We then passed the SPI NOR erase map to MTD. Users can now determine the erase regions and make informed decisions on partitions size. An optional interrupt property is now described in the bindings. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEE9HuaYnbmDhq/XIDIJWrqGEe9VoQFAmX0LpsACgkQJWrqGEe9 VoSOCwf8CLhMAsVs/9SrRPMwLuFUGD0IuYYsPl/+qOFXePQOVxNW8s8+DdVrQngW Oi+unW8MAizPAwMPL9AiyS12WbDVT2qyO0uwX5/efhxXwoNkk+F74icxDBBe1FOu tnvRRdqY6Zg94T4c1M9BnV5LtW+ozk+F9K8UsYvqnDOcOuaA64qmXRem63s0Jctu lnmCWHQ0+A8iL7RQ7OMbQswcYQlbnpt7p3lyvDc3dW8K3TRzUtP4nnabL8eiYhqu ho5SvbWhls91EYf/ij6+SFteV5KN4p+v1ymK2u/AqvCkIW8dAfiIhvvT8dWswpUV CyC44BFbj3/1ZeSQG4GCXzcNXwnztQ== =mSyp -----END PGP SIGNATURE----- Merge tag 'mtd/for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux Pull MTD updates from Miquel Raynal: "MTD: - The Carillo Ranch driver has been removed - Top level mtd bindings have received a couple of improvements (references, selects) - The ssfdc driver received few minor adjustments - The usual load of misc/small improvements and fixes Raw NAND: - The main series brought is an update of the Broadcom support to support all BCMBCA SoCs and their specificity (ECC, write protection, configuration straps), plus a few misc fixes and changes in the main driver.

- Sumanth Korikkar has taught s390 to allocate hotplug-time page frames
from hotplugged memory rather than only from main memory. Series "implement "memmap on memory" feature on s390". - More folio conversions from Matthew Wilcox in the series "Convert memcontrol charge moving to use folios" "mm: convert mm counter to take a folio" - Chengming Zhou has optimized zswap's rbtree locking, providing significant reductions in system time and modest but measurable reductions in overall runtimes. The series is "mm/zswap: optimize the scalability of zswap rb-tree". - Chengming Zhou has also provided the series "mm/zswap: optimize zswap lru list" which provides measurable runtime benefits in some swap-intensive situations. - And Chengming Zhou further optimizes zswap in the series "mm/zswap: optimize for dynamic zswap_pools". Measured improvements are modest. - zswap cleanups and simplifications from Yosry Ahmed in the series "mm: zswap: simplify zswap_swapoff()". - In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has contributed several DAX cleanups as well as adding a sysfs tunable to control the memmap_on_memory setting when the dax device is hotplugged as system memory. - Johannes Weiner has added the large series "mm: zswap: cleanups", which does that. - More DAMON work from SeongJae Park in the series "mm/damon: make DAMON debugfs interface deprecation unignorable" "selftests/damon: add more tests for core functionalities and corner cases" "Docs/mm/damon: misc readability improvements" "mm/damon: let DAMOS feeds and tame/auto-tune itself" - In the series "mm/mempolicy: weighted interleave mempolicy and sysfs extension" Rakie Kim has developed a new mempolicy interleaving policy wherein we allocate memory across nodes in a weighted fashion rather than uniformly. This is beneficial in heterogeneous memory environments appearing with CXL. - Christophe Leroy has contributed some cleanup and consolidation work against the ARM pagetable dumping code in the series "mm: ptdump: Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute". - Luis Chamberlain has added some additional xarray selftesting in the series "test_xarray: advanced API multi-index tests". - Muhammad Usama Anjum has reworked the selftest code to make its human-readable output conform to the TAP ("Test Anything Protocol") format. Amongst other things, this opens up the use of third-party tools to parse and process out selftesting results. - Ryan Roberts has added fork()-time PTE batching of THP ptes in the series "mm/memory: optimize fork() with PTE-mapped THP". Mainly targeted at arm64, this significantly speeds up fork() when the process has a large number of pte-mapped folios. - David Hildenbrand also gets in on the THP pte batching game in his series "mm/memory: optimize unmap/zap with PTE-mapped THP". It implements batching during munmap() and other pte teardown situations. The microbenchmark improvements are nice. - And in the series "Transparent Contiguous PTEs for User Mappings" Ryan Roberts further utilizes arm's pte's contiguous bit ("contpte mappings"). Kernel build times on arm64 improved nicely. Ryan's series "Address some contpte nits" provides some followup work. - In the series "mm/hugetlb: Restore the reservation" Breno Leitao has fixed an obscure hugetlb race which was causing unnecessary page faults. He has also added a reproducer under the selftest code. - In the series "selftests/mm: Output cleanups for the compaction test", Mark Brown did what the title claims. - Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring". - Even more zswap material from Nhat Pham. The series "fix and extend zswap kselftests" does as claimed. - In the series "Introduce cpu_dcache_is_aliasing() to fix DAX regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in our handling of DAX on archiecctures which have virtually aliasing data caches. The arm architecture is the main beneficiary. - Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic improvements in worst-case mmap_lock hold times during certain userfaultfd operations. - Some page_owner enhancements and maintenance work from Oscar Salvador in his series "page_owner: print stacks and their outstanding allocations" "page_owner: Fixup and cleanup" - Uladzislau Rezki has contributed some vmalloc scalability improvements in his series "Mitigate a vmap lock contention". It realizes a 12x improvement for a certain microbenchmark. - Some kexec/crash cleanup work from Baoquan He in the series "Split crash out from kexec and clean up related config items". - Some zsmalloc maintenance work from Chengming Zhou in the series "mm/zsmalloc: fix and optimize objects/page migration" "mm/zsmalloc: some cleanup for get/set_zspage_mapping()" - Zi Yan has taught the MM to perform compaction on folios larger than order=0. This a step along the path to implementaton of the merging of large anonymous folios. The series is named "Enable >0 order folio memory compaction". - Christoph Hellwig has done quite a lot of cleanup work in the pagecache writeback code in his series "convert write_cache_pages() to an iterator". - Some modest hugetlb cleanups and speedups in Vishal Moola's series "Handle hugetlb faults under the VMA lock". - Zi Yan has changed the page splitting code so we can split huge pages into sizes other than order-0 to better utilize large folios. The series is named "Split a folio to any lower order folios". - David Hildenbrand has contributed the series "mm: remove total_mapcount()", a cleanup. - Matthew Wilcox has sought to improve the performance of bulk memory freeing in his series "Rearrange batched folio freeing". - Gang Li's series "hugetlb: parallelize hugetlb page init on boot" provides large improvements in bootup times on large machines which are configured to use large numbers of hugetlb pages. - Matthew Wilcox's series "PageFlags cleanups" does that. - Qi Zheng's series "minor fixes and supplement for ptdesc" does that also. S390 is affected. - Cleanups to our pagemap utility functions from Peter Xu in his series "mm/treewide: Replace pXd_large() with pXd_leaf()". - Nico Pache has fixed a few things with our hugepage selftests in his series "selftests/mm: Improve Hugepage Test Handling in MM Selftests". - Also, of course, many singleton patches to many things.
