arm64: Widen hwcap to be 64 bit
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. Signed-off-by: Steve Capper <steve.capper@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
