Peter Anvin" <hpa@...or.com>, Linus Torvalds <torvalds@...ux-foundation.org>, Oleg Nesterov <oleg@...hat.com>, Thomas Gleixner <tglx@...utronix.de> Subject: [PATCH 041/208] x86/fpu: Remove __save_init_fpu() __save_init_fpu() is just a trivial wrapper around fpu_save_init(). Remove the extra layer of obfuscation.
