Pull EFI updates from Ard Biesheuvel:
"Although some more stuff is brewing, the EFI changes that are ready
for mainline are few this cycle:
- improve the PCI DMA paranoia logic in the EFI stub
- some constification changes
- add statfs support to efivarfs
- allow user space to enumerate updatable firmware resources without
CAP_SYS_ADMIN"
* tag 'efi-next-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi:
efi/libstub: Disable PCI DMA before grabbing the EFI memory map
efi/esrt: Allow ESRT access without CAP_SYS_ADMIN
efivarfs: expose used and total size
efi: make kobj_type structure constant
efi: x86: make kobj_type structure constant
