This is a resend of the generic part of the series 'efi interruptible runtime
services', of which v3 was sent out on January 13th. I have added an additional
patch on top which gives runtime-wrappers.c the same treatment as efivars.c,
i.e., replacing the spinlock with a semaphore.
v2: rebase onto v4.7-rc3
pr_warn() on failure to acquire the rt services semaphore before invoking
the reset_system runtime service
map EFI_ABORTED onto -EINTR
v3: drop lockdep_assert_xxx() calls (#2)
Ard Biesheuvel (1):
efi: replace runtime services spinlock with semaphore
Sylvain Chouleur (2):
efi: use a file local lock for efivars
efi: don't use spinlocks for efi vars
