[GIT pull] x86/urgent for v6.5-rc1

[Thomas Gleixner]

Linus,

please pull the latest x86/urgent branch from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-urgent-2023-07-01

up to:  0303c9729afc: x86/efi: Make efi_set_virtual_address_map IBT safe


A single regression fix for x86:

  Moving the invocation of arch_cpu_finalize_init() earlier in the boot
  process caused a boot regression on IBT enabled system.

  The root cause is not the move of arch_cpu_finalize_init() itself. The
  system fails to boot because the subsequent efi_enter_virtual_mode() code
  has a non-IBT safe EFI call inside. This was never noticed because IBT
  was enabled after the EFI initialization.

  Switching the EFI call to use the IBT safe wrapper cures the problem.

Thanks,

	tglx
