Subject: powerpc/rfi-flush: Call setup_rfi_flush() after LPM migration
X-Git-Tag: v5.15~9084^2~97
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=921bc6cf807ceb2ab8005319cf39f33494d6b100;p=platform%2Fkernel%2Flinux-starfive.git

powerpc/rfi-flush: Call setup_rfi_flush() after LPM migration

We might have migrated to a machine that uses a different flush type,
or doesn't need flushing at all.
