Subject: Please revert 7212e37cbdf9 from 4.4-stable
Date: Mon, 11 Mar 2019 13:48:14 +0000	[thread overview]
Message-ID: <20190311134814.GC30367@sarge.linuxathome.me> (raw)

Hi Greg,

Could you please revert

	7212e37cbdf9 x86/platform/UV: Use efi_runtime_lock to serialise BIOS calls

from 4.4-stable?

In 4.4-stable efi_runtime_lock as defined in drivers/firmware/efi/runtime-wrappers.c
is a spinlock (given it predates commit dce48e351c0d) and commit

	f331e766c4be x86/platform/UV: Use efi_runtime_lock to serialise BIOS calls

which 7212e37cbdf9 is a backport of, needs it to be a semaphore.

Cheers,
Hedi.
