Subject: [PATCH] drivers/firmware/efi/efivars.c: use in_compat_syscall() to
check for compat callers
This should make no difference on any architecture, as x86's historical
is_compat_task behavior really did check whether the calling syscall was
a compat syscall. x86's is_compat_task is going away, though.
