With recent cleanups and fixes the fpu__reset() and fpu__clear() functions have become almost identical in functionality: the only difference is that fpu__reset() assumed that the fpstate was already active in the eagerfpu case, while fpu__clear() activated it if it was inactive. This distinction almost never matters, the only case where such fpstate activation happens if if the init thread (PID 1) gets exec()-ed for the first time. So keep fpu__clear() and change all fpu__reset() uses to fpu__clear() to simpify the logic. ( In a later patch we'll further simplify fpu__clear() by making sure that all contexts it is called on are already active. ) Cc: Andy Lutomirski <luto@amacapital.net> Cc: Borislav Petkov <bp@alien8.de> Cc: Dave Hansen <dave.hansen@linux.intel.com> Cc: Fenghua Yu <fenghua.yu@intel.com> Cc: H.
