[PATCH 04/14] powerpc/64s/exception: machine check adjust RFI target

flat view
STALE2662d

From: Nicholas Piggin <npiggin@gmail.com>
Date: 2019-07-03 08:05:06
Subsystem: linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Linus Torvalds

The host kernel delivery case for powernv does RFI_TO_USER_OR_KERNEL,
but should just use RFI_TO_KERNEL which makes it clear this is not a
user case.

This is not a bug because RFI_TO_USER_OR_KERNEL deals with kernel
returns just fine.
