Subject: x86/fpu: Rename fpstate_alloc_init() to fpstate_init_curr()
X-Git-Tag: omap-for-v4.3/legacy-v2-signed~203^2~115
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e62bb3d894d312a37009fb07dc83fd1cc7bed37c;p=pandora-kernel.git

x86/fpu: Rename fpstate_alloc_init() to fpstate_init_curr()

Now that there are no FPU context allocations, rename fpstate_alloc_init()
to fpstate_init_curr(), to signal that it initializes the fpstate and
marks it active, for the current task.
