Under arm64 elf_hwcap is a 32 bit quantity, but it is stored in
a 64 bit auxiliary ELF field and glibc reads hwcap as 64 bit.
This patch widens elf_hwcap to be 64 bit.

This patch adds #ifdef __KERNEL__ guards around the COMPAT_* definitions
to avoid exporting them to user. AArch32 user requiring the kernel
headers must use those generated with ARCH=arm.

Split compound conditionals containing __KERNEL__ in Arm64 where possible to
make it easier for the UAPI disintegration scripts to handle them.

This patch adds definitions for the ELF format, including personality
