a4eb355a3f arm64: vdso: Fix CFI directives in sigreturn trampoline
Daniel reports that the .cfi_startproc is misplaced for the sigreturn
trampoline, which causes LLVM's unwinder to misbehave:

  | I run into this with LLVM’s unwinder.
  | This combination was always broken.

This prompted Dave to question our use of CFI directives more generally,
and I ended up going down a rabbit hole trying to figure out how this
very poorly documented stuff gets used.

Move the CFI directives so that the "mysterious NOP" is included in
the .cfi_{start,end}proc block and add a bunch of comments so that I
can save myself another headache in future.

9a96428557 arm64: vdso: Don't prefix sigreturn trampoline with a BTI C instruction
For better or worse, GDB relies on the exact instruction sequence in the
VDSO sigreturn trampoline in order to unwind from signals correctly.
Commit c91db232da ("arm64: vdso: Convert to modern assembler annotations")
unfortunately added a BTI C instruction to the start of __kernel_rt_sigreturn,
which breaks this check. Thankfully, it's also not required, since the
trampoline is called from a RET instruction when returning from the signal
handler

Remove the unnecessary BTI C instruction from __kernel_rt_sigreturn,
and do the same for the 32-bit VDSO as well for good measure.

DTS changes for omaps for v5.8 merge window

We add support for beaglebone-ai board that's am5729 based devices.

Then we have a series changes to configure more hardware acceletators found
on omap variants. With the recent ti-sysc related changes, we can now better
configure the accelerators with help of the clock framework and reset driver.
So with a series of changes from Suman Anna and Tero Kristo, let's configure
IPUs and DSPs for dra7 devices like beagle-x15. And let's also configure the
missing crypto accelerators for omap5 as those have been missing.

Note that there are still some pending driver related patches to use IPU and
DSP related features with mainline kernel, but those are independent of the
devicetree changes.

Then there is a display related change for am57xx-idk for tc358778 bridge,
and a change to configure the missing clock source for some PWM timers.

bbb5946eb5 mips: MAAR: Use more precise address mask
Indeed according to the MIPS32 Privileged Resource Architecgture the MAAR
pair register address field either takes [12:31] bits for non-XPA systems
and [12:55] otherwise. In any case the current address mask is just
wrong for 64-bit and 32-bits XPA chips. So lets extend it to 59-bits
of physical address value. This shall cover the 64-bits architecture and
systems with XPA enabled, and won't cause any problem for non-XPA 32-bit
systems, since address values exceeding the architecture specific MAAR
mask will be just truncated with setting zeros in the unsupported upper
bits.

ad5a57dfe4 firmware: smccc: Drop smccc_version enum and use ARM_SMCCC_VERSION_1_x instead
Instead of maintaining 2 sets of enums/macros for tracking SMCCC version,
let us drop smccc_version enum and use ARM_SMCCC_VERSION_1_x directly
instead.

This is in preparation to drop smccc_version here and move it separately
under drivers/firmware/smccc.

f73531f025 arm64/cpufeature: Drop open encodings while extracting parange
Currently there are multiple instances of parange feature width mask open
encodings while fetching it's value. Even the width mask value (0x7) itself
is not accurate. It should be (0xf) per ID_AA64MMFR0_EL1.PARange[3:0] as in
ARM ARM (0487F.a). Replace them with cpuid_feature_extract_unsigned_field()
which can extract given standard feature (4 bits width i.e 0xf mask) field.

In order to alloc sub-arches to alloc KASAN regions using optimised
methods (Huge pages on 8xx, BATs on BOOK3S, ...), declare
kasan_init_region() weak.

Also make kasan_init_shadow_page_tables() accessible from outside,
so that it can be called from the specific kasan_init_region()
functions if needed.

And populate remaining KASAN address space only once performed
the region mapping, to allow 8xx to allocate hugepd instead of
standard page tables for mapping via 8M hugepages.

Since then commit 47febbeeec ("powerpc/32: Force KASAN_VMALLOC for

The spinlocking has then become unneeded and can be removed to
simplify kasan_init_shadow_page_tables()

which are not needed anymore since the removal of modules management.

3a66a24f60 powerpc/kasan: Fix issues by lowering KASAN_SHADOW_END
At the time being, KASAN_SHADOW_END is 0x100000000, which
is 0 in 32 bits representation.

This leads to a couple of issues:
- kasan_remap_early_shadow_ro() does nothing because the comparison
k_cur < k_end is always false.
- In ptdump, address comparison for markers display fails and the
marker's name is printed at the start of the KASAN area instead of
being printed at the end.

However, there is no need to shadow the KASAN shadow area itself,
so the KASAN shadow area can stop shadowing memory at the start
of itself.

With a PAGE_OFFSET set to 0xc0000000, KASAN shadow area is then going
from 0xf8000000 to 0xff000000.

8f53f9c0f6 powerpc/book3s64/radix/tlb: Determine hugepage flush correctly
With a 64K page size flush with start and end:

  (start, end) = (721f680d0000, 721f680e0000)

results in:

  (hstart, hend) = (721f68200000, 721f68000000)

ie. hstart is above hend, which indicates no huge page flush is
needed.

However the current logic incorrectly sets hflush = true in this case,
because hstart != hend.

That causes us to call __tlbie_va_range() passing hstart/hend, to do a
huge page flush even though we don't need to. __tlbie_va_range() will
skip the actual tlbie operation for start > end. But it will still end
up calling fixup_tlbie_va_range() and doing the TLB fixups in there,
which is harmless but unnecessary work.
