Subject: cache_k8_northbridges() overflows beyond allocation
X-Git-Tag: v2.6.21~80
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6f29e35e2d4cdbc3e8785982314e54ec5df4ad37;p=linux-2.6

cache_k8_northbridges() overflows beyond allocation

cache_k8_northbridges() is storing config values to incorrect locations
(in flush_words) and also its overflowing beyond the allocation, causing
slab verification failures.
