For a number of years, UAPI headers have been split from kernel-internal headers. The latter are never exposed to userspace, and always built with __KERNEL__ defined. Most headers under arch/arm64 don't have __KERNEL__ guards, but there are a few stragglers lying around. To make things more consistent, and to set a good example going forward, let's remove these redundant __KERNEL__ guards. In a couple of cases, a trailing #endif lacked a comment describing its corresponding #if or #ifdef, so these are fixes up at the same time. Guards in auto-generated crypto code are left as-is, as these guards are generated by scripting imported from the upstream openssl project scripts. Guards in UAPI headers are left as-is, as these can be included by userspace or the kernel. There should be no functional change as a result of this patch.
