Subject: x86/fpu: Rename fpu__activate_fpstate() to fpu__activate_fpstate_write()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6a81d7eb330479c908dab3a47ac33cfca8af5a67;p=openwrt%2Fstaging%2Fblogic.git

x86/fpu: Rename fpu__activate_fpstate() to fpu__activate_fpstate_write()

Remaining users of fpu__activate_fpstate() are all places that want to modify
FPU registers, rename the function to fpu__activate_fpstate_write() according
to this usage.
