Merge branch 'for-next/sysreg-hwcaps' into for-next/core
* for-next/sysreg-hwcaps: : Make use of sysreg helpers for hwcaps arm64/cpufeature: Use helper macros to specify hwcaps arm64/cpufeature: Always use symbolic name for feature value in hwcaps arm64/sysreg: Initial unsigned annotations for ID registers arm64/sysreg: Initial annotation of signed ID registers arm64/sysreg: Allow enumerations to be declared as signed or unsigned
