SYM_FUNC_START_LOCAL_NOALIGN() adds an endbr leading to this layout
(leaving only the last 2 bytes of the address):

However, "the RET at __x86_return_thunk must be on a 64 byte boundary,
for alignment within the BTB."

Use SYM_START instead.

Commit c76c6c4ecbec0deb5 ("ARM: 9294/2: vfp: Fix broken softirq handling
with instrumentation enabled") updated the VFP exception entry logic to
go via a C function, so that we get the compiler's version of
local_bh_disable(), which may be instrumented, and isn't generally
callable from assembler.

However, this assumes that passing an alternative 'success' return
address works in C as it does in asm, and this is only the case if the C
calls in question are tail calls, as otherwise, the stack will need some
unwinding as well.

I have already sent patches to the list that replace most of the asm
logic with C code, and so it is preferable to have a minimal fix that
addresses the issue and can be backported along with the commit that it

fixes to v6.3 from v6.4. Hopefully, we can land the C conversion for v6.5.

So instead of passing the 'success' return address as a function
argument, pass the stack address from where to pop it so that both LR
and SP have the expected value.

kernel/pi gives rise to a lot of new sections that end up orphans: the
first attempt to fix that tried to enumerate them all in the linker
script, but kernel test robot with a random config keeps finding more of
them.

So prefix all those sections with .init.pi instead of only .init in
order to be able to easily catch them all in the linker script.

Commit

  310e782a99c7 ("platform/x86/amd: pmc: Utilize SMN index 0 for driver probe")

switched to using amd_smn_read() which relies upon the misc PCI ID used
by DF function 3 being included in a table.  The ID for model 78h is
missing in that table, so amd_smn_read() doesn't work.

Add the missing ID into amd_nb, restoring s2idle on this system.
