Subject: [PATCH v3 0/3] x86/fpu: Allow the In-Field Scan driver to initialize FPU state
This revision switches to a new approach by providing a helper to
initialize user FPU states for the driver, which is considerably simpler.
This approach could serve as an example for addressing similar situations
from a non-critical path.
I thought fpu_reset_fpregs() as the helper name. There is already one
with this name. Then, I realized the existing one is a bit misaligned, so
renamed it first here.
Thanks to Dave for the reviews and the suggestion.
Thanks,
Chang
