On arm64 52-bit VAs are provided to userspace when a hint is supplied to mmap. This helps maintain compatibility with software that expects at most 48-bit VAs to be returned. In order to help identify software that has 48-bit VA assumptions, this patch allows one to compile a kernel where 52-bit VAs are returned by default on HW that supports it. This feature is intended to be for development systems only. Signed-off-by: Steve Capper <redacted>Acked-by: Catalin Marinas <catalin.marinas@arm.com>
