This series cleans up a number of things in the code that issues secure monitor ("smc") requests for the bcm281xx and bcm21664 SoC families. This code is currently used only for enabling the level-2 cache.
There are some bug fixes and other improvements. An assembly language file containing a single function has been eliminated by re-implementing the code using inline assembly. Some comments have been expanded and clarified. Kernel configuration options allow finer-grained control over how this code gets built. Finally, the "kona.c" and "kona.h" files are renamed to reflect the fact that only contain code related to level-2 cache support.
This series is based on v3.15-rc2, and depends on one patch posted previously: [PATCH v4] mach-bcm: clean up config and build targets https://lkml.org/lkml/2014/4/15/303
It is available here: http://git.linaro.org/landing-teams/working/broadcom/kernel.git Branch review/bcm-smc-cleanup-v2
