Subject: x86/fpu: Rename fpu_reset_fpregs() to fpu_reset_fpstate_regs()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=de8304c319bc020ef79d109909ad40e944d82c82;p=users%2Fwilly%2Fxarray.git

x86/fpu: Rename fpu_reset_fpregs() to fpu_reset_fpstate_regs()

The original function name came from an overly compressed form of
'fpstate_regs' by commit:

    e61d6310a0f8 ("x86/fpu: Reset permission and fpstate on exec()")

However, the term 'fpregs' typically refers to physical FPU registers. In
contrast, this function copies the init values to fpu->fpstate->regs, not
hardware registers.

Rename the function to better reflect what it actually does.

No functional change.
