[PATCH 0/4] arm64: cpucap cleanup

[Mark Rutland]

Currently arm64 uses inconsistent terminology when handling cpucaps,
with different places in the code referring to these as "capabilities",
"features", "cpufeatures", "hwcaps", and "cpu_hwcaps" with the latter
two easily being confused with the ELF hwcaps.

Similarly, the bitmaps used to store the boot and system cpucaps are
named "boot_capabilities" and "cpu_hwcaps" respectively.

All of this is unnecessarily confusing.

This series tries to apply a consistent "cpucap" naming scheme,
following the example of "asm/cpucaps.h" where the cpucap values are
defined. This clearly separates these from the ELF hwcaps, and makes it
easier to understand the code.

I've split this out from a larger rework of the cpucap logic, as that
larger rework isn't yet ready and I think this stands on its own as a
nice cleanup.

There should be no functional change as a result of this series.

Thanks,
Mark.
