[PATCH 0/4] x86/asm: .byte removal

Posted by Andrew Cooper 1 month, 1 week ago

The remaining conversion of .byte to real instructions following the toolchain
upgrade.

https://gitlab.com/xen-project/hardware/xen-staging/-/pipelines/2237162011

Andrew Cooper (4):
  x86/xstate: Deindent the logic in xrstor()
  x86/xstate: Rework XSAVE/XRSTOR given a newer toolchain baseline
  x86/i387: Rework fpu_fxrstor() given a newer toolchain baseline
  x86: Avoid using .byte for instructions where safe to do so
