Subject[PATCH 109/208] x86/fpu: Clean up eager_fpu_init() and rename it to fpu__ctx_switch_init()
Date
It's not an xsave specific function anymore, so rename it accordingly
and also clean it up a bit:

- remove the obsolete __init_refok, as the code paths are not
mixed anymore

- rename it from eager_fpu_init() to fpu__ctx_switch_init()

- remove stray 'return;'

- make it static to its only user
