[Qemu-devel] [PATCH 1/3] powerpc: scan_features() updates incorrect bits


From: Anton Blanchard
Subject: [Qemu-devel] [PATCH 1/3] powerpc: scan_features() updates incorrect bits
Date: Fri, 15 Apr 2016 12:06:13 +1000

The real LE feature entry in the ibm_pa_feature struct has the
wrong number of elements. Instead of checking for byte 5, bit 0,
we check for byte 0, bit 0, and we also incorrectly update cpu user
feature bit 5.

Fixes: 44ae3ab3358e ("powerpc: Free up some CPU feature bits by moving out 
MMU-related features")
