Subject: [PATCH v2 0/2] powerpc/rtas: improved busy and extended delay status handling

From: Nathan Lynch <[email-masked]>

This can be considered a successor to:

https://lore.kernel.org/linuxppc-dev/[email-masked]/

which tried to address both the suboptimal delay behavior as well as API
issues. This version achieves the performance improvements and leaves major
API changes for another time.

Changes since v1:
* Drop major API changes.
* Avoid division when calculating the arguments to usleep_range() (Alexey).
* Improve kernel-doc for rtas_busy_delay(), rtas_busy_delay_time().
