Subject: [GIT PULL] arm64 fixes for -rc5

Hi Linus,

When you get a moment, please can you pull these three small arm64 fixes?
They're all related to optional architecture extensions: BTI, SME and
52-bit virtual addressing.

Summary in the tag.

Cheers,

Will

  arm64: mm: fix resume for 52-bit enabled builds (2022-09-10 14:46:28 +0100)

----------------------------------------------------------------
arm64 fixes for -rc5

- Disable in-kernel BTI when compiling with GCC, as it makes invalid
  assumptions about the distance between functions which has led to
  crashes when calling modules on a CPU with BTI support.

- Remove bogus TIF_SME flag management if memory allocation fails in the
  ptrace code.

- Fix the resume path when configured for 52-bit virtual addressing.
