Pull EFI updates from Ard Biesheuvel:
 "Only a handful of changes this cycle, consisting of cleanup work and a
  low-prio bugfix:

   - Additional cleanup by Tim for the efivarfs variable name length
     confusion

   - Avoid freeing a bogus pointer when virtual remapping is omitted in
     the EFI boot stub"

* tag 'efi-next-for-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi:
  efi: libstub: only free priv.runtime_map when allocated
  efi: Clear up misconceptions about a maximum variable name size
  efivarfs: Remove unused internal struct members
  Documentation: Mark the 'efivars' sysfs interface as removed
  efi: pstore: Request at most 512 bytes for variable names
