Merge tag 'efi-urgent-2020-08-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull EFI fixes from Thomas Gleixner:
- Enforce NX on RO data in mixed EFI mode
- Destroy workqueue in an error handling path to prevent UAF
- Stop argument parser at '--' which is the delimiter for init
- Treat a NULL command line pointer as empty instead of dereferncing it
unconditionally.
- Handle an unterminated command line correctly
- Cleanup the 32bit code leftovers and remove obsolete documentation
