From 6b862ba1821441e6083cf061404694d33a841526 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 23 Jun 2021 14:01:53 +0200 Subject: x86/fpu: Rename copy_user_to_xregs() and copy_xregs_to_user() The function names for xsave[s]/xrstor[s] operations are horribly named and a permanent source of confusion. Rename: copy_xregs_to_user() to xsave_to_user_sigframe() copy_user_to_xregs() to xrstor_from_user_sigframe() so it's entirely clear what this is about. This is also a clear indicator of the potentially different storage format because this is user ABI and cannot use compacted format. No functional change.
