Hi Linus,

Please pull another small set of EFI fixes below. Only the x86 one is likely to
affect any actual users (and has a cc:stable), but the issue it fixes was only
observed in an unusual context (kexec in a confidential VM).

The following changes since commit 99280413a5b785f22d91e8a8a66dc38f4a214495:

  efi: Add missing __nocfi annotations to runtime wrappers (2024-06-05 10:18:58 +0200)

are available in the Git repository at:

  efi/arm64: Fix kmemleak false positive in arm64_efi_rt_init() (2024-06-15 10:25:02 +0200)

----------------------------------------------------------------
EFI fixes for v6.10 #3

- Ensure that EFI runtime services are not unmapped by PAN on ARM
- Avoid freeing the memory holding the EFI memory map inadvertently on
  x86
- Avoid a false positive kmemleak warning on arm64

----------------------------------------------------------------
Ard Biesheuvel (2):
      efi/arm: Disable LPAE PAN when calling EFI runtime services
      efi/x86: Free EFI memory map only when installing a new one.

Waiman Long (1):
      efi/arm64: Fix kmemleak false positive in arm64_efi_rt_init()
