Subject: gianfar: Use memset instead of cacheable_memzero
X-Git-Tag: v2.6.31-rc1~330^2~520
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=6c31d55f755ff2bc1f7dc3b45c500032fe90aff8;p=~emulex%2Finfiniband.git

gianfar: Use memset instead of cacheable_memzero

cacheable_memzero() is completely overkill for the clearing out the FCB
block which is only 8-bytes.  The compiler should easily optimize this
with memset.  Additionally, cacheable_memzero() only exists on ppc32 and
thus breaks builds of gianfar on ppc64.
