Subject: [PATCH stable 4.9 01/23] powerpc/rfi-flush: Move out of HARDLOCKUP_DETECTOR #ifdef
Date: Sat, 2 Jun 2018 21:08:46 +1000 [thread overview]
Message-ID: <20180602110908.29773-2-mpe@ellerman.id.au> (raw)
In-Reply-To: <20180602110908.29773-1-mpe@ellerman.id.au>
The backport of the RFI flush support, done by me, has a minor bug in
that the code is inside an #ifdef CONFIG_HARDLOCKUP_DETECTOR, which is
incorrect.
This doesn't matter with common configs because we enable
HARDLOCKUP_DETECTOR, but with future patches it will break the build.
So fix it.
Fixes: c3b82ebee6e0 ("powerpc/64s: Add support for RFI flush of L1-D cache")
