Linus Torvalds 087aa69a9f 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.

 "Three small arm64 fixes, all related to optional architecture
  extensions: BTI, SME and 52-bit virtual addressing:

   - 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
