Subject: [POWERPC] FWNMI is only used on pSeries
X-Git-Tag: v2.6.24-rc1~1450^2~203
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=9e4859ef5462193643fd2b3c8ffb298e5a4a4319;p=linux.git

[POWERPC] FWNMI is only used on pSeries

This saves 4k on non pSeries builds (except for iSeries where it saves
almost 4k).
