Subject: [PATCH] powerpc/pseries: Fix IBM_ARCH_VEC_NRCORES_OFFSET for POWER8 updates
Date: Thu, 15 Nov 2012 14:53:12 +1100 [thread overview]
Message-ID: <23719.1352951592@neuling.org> (raw)
In-Reply-To: <30008.1352442191@neuling.org>
In supporting POWER8 we added 16 bytes to the start of the
ibm_architecture_vec, but forgot to add this to
IBM_ARCH_VEC_NRCORES_OFFSET.
This caused us to hit this warning in early boot:
WARNING ! ibm_architecture_vec structure inconsistent: 805372128
This add this extra 16 bytes of offset.
