* For userspace we represent hwcaps as a collection of HWCAP{,2}_x bitfields
* as described in uapi/asm/hwcap.h. For the kernel we represent hwcaps as
* natural numbers (in a single range of size MAX_CPU_FEATURES) defined here
* with prefix KERNEL_HWCAP_ mapped to their HWCAP{,2}_x counterpart.
*
* Hwcaps should be set and tested within the kernel via the
* cpu_{set,have}_named_feature(feature) where feature is the unique suffix
* of KERNEL_HWCAP_{feature}.
