Subject: selftests/mm: fix validate_addr() helper
Date: Fri, 20 Jun 2025 16:41:50 +0530

validate_addr() checks whether the address returned by mmap() lies in the
low or high VA space, according to whether a high addr hint was passed or
not.  The fix commit mentioned below changed the code in such a way that
this function will always return failure when passed high_addr == 1; addr
will be >= HIGH_ADDR_MARK always, we will fall down to "if (addr >
HIGH_ADDR_MARK)" and return failure.  Fix this.
