x86/fpu: Simplify fpstate_init_curr() usage
Now that fpstate_init_curr() is not doing implicit allocations anymore, almost all uses of it involve a very simple pattern: if (!fpu->fpstate_active) fpstate_init_curr(fpu); which is basically activating the FPU fpstate if it was not active before. So propagate the check into the function itself, and rename the function according to its new purpose: fpu__activate_curr(fpu); Reviewed-by: Borislav Petkov <bp@alien8.de> Cc: Andy Lutomirski <luto@amacapital.net> Cc: Dave Hansen <dave.hansen@linux.intel.com> Cc: Fenghua Yu <fenghua.yu@intel.com> Cc: H.
