Subject: x86/fpu: Rename save_user_xstate() to copy_fpregs_to_sigframe()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2a52af8b8adc498b3cccbc219ec997cad6cafb9c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

x86/fpu: Rename save_user_xstate() to copy_fpregs_to_sigframe()

Move the naming in line with existing names, so that we now have:

  copy_fpregs_to_fpstate()
  copy_fpstate_to_sigframe()
  copy_fpregs_to_sigframe()

... where each function does what its name suggests.
