x86/fpu/init: Propagate __init annotations

2015-05-19T13:48:11+00:00

Now that all the FPU init function call dependencies are cleaned up we can propagate __init annotations deeper. This shrinks the runtime size of the kernel a bit, and also addresses a few section warnings. Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Dave Hansen Cc: Fenghua Yu Cc: H.

x86/fpu: Make check_fpu() init ordering independent

2015-05-19T13:47:46+00:00

check_fpu() currently relies on being called early in the init sequence, when CR0::TS has not been set up yet. Save/restore CR0::TS across this function, to make it invariant to init ordering. This way we'll be able to move the generic FPU setup routines earlier in the init sequence. Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Dave Hansen Cc: Fenghua Yu Cc: H.

x86/fpu: Factor out FPU bug checks into fpu/bugs.c

2015-05-19T13:47:45+00:00

Create separate fpu/bugs.c code so that if we read generic FPU code we don't have to wade through all the bugcheck related code first.
