Cover letter [PATCH 0/3]: x86, fpu: unlazy_fpu fixes/cleanups
Quoted 3 lines · Rik van Riel

Not only is this broken with my new code, but it looks like it may be broken with the current code, too...

Lets (try to) fix unlazy_fpu/save_init_fpu at least.

Dave, fpu_save_init() in do_bounds() and task_get_bounds_dir() looks wrong too, shouldn't it use unlazy_fpu() ? See the changelog in 3/3.

Oleg.
