Subject: x86/fpu: Rename fpu__activate_fpstate_read/write() to fpu__prepare_[read|write]()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=369a036de206710ff27a66f9bffe78ef657648c3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

x86/fpu: Rename fpu__activate_fpstate_read/write() to fpu__prepare_[read|write]()

As per the new nomenclature we don't 'activate' the FPU state
anymore, we initialize it. So drop the _activate_fpstate name
from these functions, which were a bit of a mouthful anyway,
and name them:

	fpu__prepare_read()
	fpu__prepare_write()
