Subject: [FIX PATCH] powerpc/pseries: Fix vector5 in ibm architecture vector table
Date: Tue,  6 Mar 2018 13:44:32 +0530	[thread overview]
Message-ID: <20180306081432.3653-1-bharata@linux.vnet.ibm.com> (raw)

With ibm,dynamic-memory-v2 and ibm,drc-info coming around the
same time, byte22 in vector5 of ibm architecture vector table
got set twice separately. The end result is that guest kernel
isn't advertising support for ibm,dynamic-memory-v2.

Fix this by removing the duplicate assignment of byte22.

Fixes: 02ef6dd8109b5 (powerpc: Enable support for ibm,drc-info devtree property)
Fixes: c7a3275e0f9e4 (powerpc/pseries: Revert support for ibm,drc-info devtree property)
