[PATCH 0/6] MIPS: BMIPS: RIXI and workarounds support

[Florian Fainelli <f.fainelli@xxxxxxxxx>]

Hi all,

This patch series contains some workarounds for some bug with pref30 on
Broadcom BMIPS5000 CPUs in 7344, 7346 and 7425 chips, and some other changes
to allow the use of RIXI/rotr on BMIPS4380 and BMIPS5000.

Finally, the last patch adds a debugfs entry for current_cpu_data.options since
it might be useful to debug that at a time where we set on the final CPU
options.

This is on top of mips-for-linux-next as of
a13d2abd8e617a96d235c0a528a742b347650853 ("MIPS: highmem: Turn
flush_cache_kmaps into a no-op.")

Thanks!
