| From | Ingo Molnar <> | Subject | [PATCH 114/208] x86/fpu: Do system-wide setup from fpu__detect() | Date | Tue, 5 May 2015 19:50:06 +0200 |
| |
fpu__cpu_init() is called on every CPU, so it is the wrong place to call fpu__init_system() from. Call it from fpu__detect(): this is early CPU init code, but we already have CPU features detected, so we can call the system-wide FPU init code from here.
