Merge tag 'efi-next-for-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi

Pull EFI updates from Ard Biesheuvel:

 - Measure initrd and command line using the CC protocol if the ordinary
   TCG2 protocol is not implemented, typically on TDX confidential VMs

 - Avoid creating mappings that are both writable and executable while
   running in the EFI boot services. This is a prerequisite for getting
   the x86 shim loader signed by MicroSoft again, which allows the
   distros to install on x86 PCs that ship with EFI secure boot enabled.

 - API update for struct platform_driver::remove()

* tag 'efi-next-for-v6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi:
  virt: efi_secret: Convert to platform remove callback returning void
  x86/efistub: Remap kernel text read-only before dropping NX attribute
  efi/libstub: Add get_event_log() support for CC platforms
  efi/libstub: Measure into CC protocol if TCG2 protocol is absent
  efi/libstub: Add Confidential Computing (CC) measurement typedefs
  efi/tpm: Use symbolic GUID name from spec for final events table
  efi/libstub: Use TPM event typedefs from the TCG PC Client spec
