[PATCH 0/3] x86: IST cleanup

Posted by Andrew Cooper 4 years ago

Various bits of cleanup for !CONFIG_PV builds.

Andrew Cooper (3):
  x86/S3: Use percpu_traps_init() rather than opencoding SYSCALL/SYSENTER restoration
  x86/boot: Don't enable EFER.SCE for !CONFIG_PV builds
  x86/pv: Don't use IST for NMI/#MC/#DB in !CONFIG_PV builds
