This adds support for Trust Architecture (TA) 2.1 devices to the SFP driver.
There are few differences between TA 2.1 and TA 3.0, especially for
read-only support, so just re-use the existing data.

This converts the SFP driver to use regmap. This will allow easily
supporting devices with different endians. We disallow byte-level
access, as regmap_bulk_read doesn't support it (and it's unclear what
the correct result would be when we have an endianness difference).

Trust Architecture (TA) 2.1 devices include the LS1012A, LS1021A,
LS1043A, and LS1046A. The SFP device on TA 2.1 devices is very similar
to the SFP on TA 3.0 devices. The primary difference is a few fields in
the control register. Add a compatible string.

The TA_PROG_SFP supply must be enabled to program the fuses, and
disabled to read the fuses (such as at power-on-reset). On many boards,
this supply is controlled by a jumper. The user must manually insert or
remove it at the appropriate time in the programming process. However,
on other boards this supply is controlled by an FPGA or a GPIO. In
these cases, the driver can automatically enable and disable it as
necessary.

To program fuses, it is necessary to set the fuse programming time. This
is determined based on the value of the platform clock. Add a clock
property.
Because this property is necessary for programming, it is made
mandatory. Since these bindings have not yet been present in a stable
release (though they are on track for 5.18), it is not an ABI break to
change them in this manner.

Converting binder_debug() and binder_user_error() macros into functions
reduces the overall object size by 16936 bytes when cross-compiled with
aarch64-linux-gnu-gcc 11.2.0:
$ size drivers/android/binder.o.{old,new}

65551 1616 20264 87431 15587 drivers/android/binder.o.new
This is particularly beneficial to functions binder_transaction() and
binder_thread_write() which repeatedly use these macros and are both
part of the critical path for all binder transactions.
$ nm --size vmlinux.{old,new} |grep ' binder_transaction$'

This could be for instance, retrying a failed transaction at a later

The HSSI Subsystem is a configurable set of IP blocks

Like the Ethernet group used by the N3000 card, the HSSI
Subsystem does not fully implement a network device from

Here are some small serial driver fixes, and a larger number of GSM line
discipline fixes for 5.18-rc5.
These include:
- lots of tiny n_gsm fixes for issues to resolve a number of
reported problems. Seems that people are starting to actually
use this code again.
- 8250 driver fixes for some devices
- imx serial driver fix
- amba-pl011 driver fix
All of these have been in linux-next for a while with no reported

This reverts commit 0dc23d1a8e, which caused another regression
as the pinctrl code actually expects an integer value of 0 or 1
rather than a simple boolean property.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
Synthesizing AMD leaves up to 0x80000021 caused problems with QEMU,
which assumes the *host* CPUID[0x80000000].EAX is higher or equal
to what KVM_GET_SUPPORTED_CPUID reports.
This causes QEMU to issue bogus host CPUIDs when preparing the input
to KVM_SET_CPUID2. It can even get into an infinite loop, which is
only terminated by an abort():
cpuid_data is full, no space for cpuid(eax:0x8000001d,ecx:0x3e)
To work around this, only synthesize those leaves if 0x8000001d exists
on the host. The synthetic 0x80000021 leaf is mostly useful on Zen2,
which satisfies the condition.
Fixes: f144c49e8c ("KVM: x86: synthesize CPUID leaf 0x80000021h if useful")

simple 'perf test' entry to make sure this doesn't regress.
- Remove arch specific processing of kallsyms data to fixup symbol end
address, fixing excessive memory consumption in the annotation code.

Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fix from Will Deacon:
"Rename and reallocate the PT_ARM_MEMTAG_MTE ELF segment type.
This is a fix to the MTE ELF ABI for a bug that was added during the
most recent merge window as part of the coredump support.
The issue is that the value assigned to the new PT_ARM_MEMTAG_MTE
segment type has already been allocated to PT_AARCH64_UNWIND by the
ELF ABI, so we've bumped the value and changed the name of the
identifier to be better aligned with the existing one"

elf: Fix the arm64 MTE ELF segment name and value
Drop lookup_address_in_mm() now that KVM is providing it's own variant
of lookup_address_in_pgd() that is safe for use with user addresses, e.g.
guards against page tables being torn down. A variant that provides a
non-init mm is inherently dangerous and flawed, as the only reason to use
an mm other than init_mm is to walk a userspace mapping, and
lookup_address_in_pgd() does not play nice with userspace mappings, e.g.
doesn't disable IRQs to block TLB shootdowns and doesn't use READ_ONCE()
to ensure an upper level entry isn't converted to a huge page between
checking the PAGE_SIZE bit and grabbing the address of the next level
down.
This reverts commit 13c72c060f.

Fixes for (relatively) old bugs, to be merged in both the -rc and next
development trees:
* Fix potential races when walking host page table
* Fix bad user ABI for KVM_EXIT_SYSTEM_EVENT
* Fix shadow page table leak when KVM runs nested
KVM uses lookup_address_in_mm() to detect the hugepage size that the host
uses to map a pfn. The function suffers from several issues:
- no usage of READ_ONCE(*). This allows multiple dereference of the same
page table entry. The TOCTOU problem because of that may cause KVM to
incorrectly treat a newly generated leaf entry as a nonleaf one, and
dereference the content by using its pfn value.
- the information returned does not match what KVM needs; for non-present
entries it returns the level at which the walk was terminated, as long
as the entry is not 'none'. KVM needs level information of only 'present'
entries, otherwise it may regard a non-present PXE entry as a present
large page mapping.
- the function is not safe for mappings that can be torn down, because it
does not disable IRQs and because it returns a PTE pointer which is never
safe to dereference after the function returns.
So implement the logic for walking host page tables directly in KVM, and
stop using lookup_address_in_mm().

[Inline in host_pfn_mapping_level, ensure no semantic change for its
callers. - Paolo]
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
When KVM_EXIT_SYSTEM_EVENT was introduced, it included a flags
member that at the time was unused. Unfortunately this extensibility
mechanism has several issues:
- x86 is not writing the member, so it would not be possible to use it
on x86 except for new events
- the member is not aligned to 64 bits, so the definition of the
uAPI struct is incorrect for 32- on 64-bit userspace. This is a
problem for RISC-V, which supports CONFIG_KVM_COMPAT, but fortunately
usage of flags was only introduced in 5.18.
Since padding has to be introduced, place a new field in there
that tells if the flags field is valid. To allow further extensibility,
in fact, change flags to an array of 16 values, and store how many
of the values are valid. The availability of the new ndata field
is tied to a system capability; all architectures are changed to
fill in the field.
To avoid breaking compilation of userspace that was using the flags
field, provide a userspace-only union to overlap flags with data[0].
The new field is placed at the same offset for both 32- and 64-bit
userspace.
