Subject: [PATCH 7/8] powerpc/64s: Remove "Host" from MCE logging
Date: Sat, 28 Nov 2020 17:07:27 +1000	[thread overview]
Message-ID: <20201128070728.825934-8-npiggin@gmail.com> (raw)
In-Reply-To: <20201128070728.825934-1-npiggin@gmail.com>

"Host" caused machine check is printed when the kernel sees a MCE
hit in this kernel or userspace, and "Guest" if it hit one of its
guests. This is confusing when a guest kernel handles a hypervisor-
delivered MCE, it also prints "Host".

Just remove "Host". "Guest" is adequate to make the distinction.
