This series began as a single patch[1] to convert the RTAS subsystem's internal locks to raw spinlocks. The discussion of that patch identified opportunities to update a few aspects of the RTAS API, so the series begins with those and ends with a rebased version of the original patch.
Changes since v1: - Unexport the singleton 'rtas' struct. - Remove lock and args fields from 'struct rtas_t', making them private to the RTAS subsystem. - Convert all symbol exports in rtas.c to EXPORT_SYMBOL_GPL.
