Subject: Avoid zero size allocation in cache_k8_northbridges()
X-Git-Tag: v2.6.22-rc3~65
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3c6df2a9177c010bf811c361149069e4bfd9bb11;p=pandora-kernel.git

Avoid zero size allocation in cache_k8_northbridges()

kmalloc for flush_words resulted in zero size allocation when no
k8_northbridges existed.  Short circuit the code path for this case.

Also remove uneeded zeroing of num_k8_northbridges just after checking if
it is zero.
