 * 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
