Subject: x86/fpu: Simplify the xsave_state*() methods
X-Git-Tag: omap-for-v4.2/fixes-rc1^2~174^2~220
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e261c14e41b3a3cc1da54190d56b8609bedd873;p=pandora-kernel.git

x86/fpu: Simplify the xsave_state*() methods

These functions (xsave_state() and xsave_state_booting()) have a 'mask'
argument that is always -1.

Propagate this into the functions instead and eliminate the extra argument.

Does not change the generated code, because these were inlined functions.
