x86/fpu: Rename copyin_to_xsaves()/copyout_from_xsaves() to copy_user_to_xstate()/copy_xstate_to_user()
The 'copyin/copyout' nomenclature needlessly departs from what the modern FPU code
uses, which is:
copy_fpregs_to_fpstate()
copy_fpstate_to_sigframe()
copy_fregs_to_user()
copy_fxregs_to_kernel()
copy_fxregs_to_user()
copy_kernel_to_fpregs()
copy_kernel_to_fregs()
copy_kernel_to_fxregs()
copy_kernel_to_xregs()
copy_user_to_fregs()
copy_user_to_fxregs()
copy_user_to_xregs()
copy_xregs_to_kernel()
copy_xregs_to_user()
I.e. according to this pattern, the following rename should be done:
copyin_to_xsaves() -> copy_user_to_xstate()
copyout_from_xsaves() -> copy_xstate_to_user()
or, if we want to be pedantic, denote that that the user-space format is ptrace:
copyin_to_xsaves() -> copy_user_ptrace_to_xstate()
copyout_from_xsaves() -> copy_xstate_to_user_ptrace()
But I'd suggest the shorter, non-pedantic name.
