Subject: x86/fpu: Rename 'xsave_hdr' to 'header'
X-Git-Tag: omap-for-v4.2/fixes-rc1^2~174^2~169
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3a54450b5ed1671a6adecf501a0b4d4c1d27235d;p=pandora-kernel.git

x86/fpu: Rename 'xsave_hdr' to 'header'

Code like:

           fpu->state->xsave.xsave_hdr.xstate_bv |= XSTATE_FP;

is an eyesore, because not only is the words 'xsave' and 'state'
are repeated twice times (!), but also because of the 'hdr' and 'bv'
abbreviations that are pretty meaningless at a first glance.

Start cleaning this up by renaming 'xsave_hdr' to 'header'.
