Subject: [PATCH 1/6] powerpc/booke64: fix machine check handler to use the right prolog
Date: Mon, 6 Aug 2012 16:27:03 +0300	[thread overview]
Message-ID: <1344259628-31161-2-git-send-email-mihai.caraman@freescale.com> (raw)
In-Reply-To: <1344259628-31161-1-git-send-email-mihai.caraman@freescale.com>

Machine check exception handler was using a wrong prolog. Hypervisors like
KVM which are called early from the exception handler rely on the interrupt
source.
