Linus Torvalds 5f06a790a0 arm64 fixes for -rc2

- Fix instrumentation annotations for entry code
 
 - Ensure kernel MTE state is restored correctly on resume from suspend
 
 - Fix MTE fault from new strlen() routine
 
 - Fallback to byte-wise accesses on initial uaccess fault
 
 - Bump Clang requirement for BTI
 
 - Revert ARCH_DMA_MINALIGN back to 128 bytes (shakes fist at Qualcomm)

Pull arm64 fixes from Will Deacon:
 "The bulk of the diffstat consists of changes to our uaccess routines
  so that they fall back to bytewise copying prior to reporting complete
  failure when the initial (multi-byte) access faults.

  However, the most disappointing change here is that we've had to bump
  ARCH_DMA_MINALIGN back to 128 bytes thanks to Qualcomm's "Kryo" CPU,
  which ended up in the MSM8996 mobile SoC. Still, at least we're now
  aware of this design and one of the hardware designers confirmed the
  L2 cacheline size for us.

  Summary:

   - Fix instrumentation annotations for entry code

   - Ensure kernel MTE state is restored correctly on resume from suspend

   - Fix MTE fault from new strlen() routine

   - Fallback to byte-wise accesses on initial uaccess fault

   - Bump Clang requirement for BTI

   - Revert ARCH_DMA_MINALIGN back to 128 bytes (shakes fist at Qualcomm)"
