Linus Torvalds efb9666e90 A pile of fixes for x86:
- Fix the I/O bitmap invalidation on XEN PV, which was overlooked in the
    recent ioperm/iopl rework. This caused the TSS and XEN's I/O bitmap to
    get out of sync.
 
  - Use the proper vectors for HYPERV.
 
  - Make disabling of stack protector for the entry code work with GCC
    builds which enable stack protector by default. Removing the option is
    not sufficient, it needs an explicit -fno-stack-protector to shut it
    off.
 
  - Mark check_user_regs() noinstr as it is called from noinstr code. The
    missing annotation causes it to be placed in the text section which
    makes it instrumentable.
 
  - Add the missing interrupt disable in exc_alignment_check()
 
  - Fixup a XEN_PV build dependency in the 32bit entry code
 
  - A few fixes to make the Clang integrated assembler happy
 
  - Move EFI stub build to the right place for out of tree builds
 
  - Make prepare_exit_to_usermode() static. It's not longer called from ASM
    code.
