[PATCH] D47146: Memorysanitizer fix mmap test for oses not supporting MAP_NORESERVE flag

Two questions,

1. How does MSan work at all if MAP_NORESERVE is not implemented? Is it actually the default setting, and it's the opposite behavior that is not implemented?
2. If the flag is defined in the headers but ignored by the kernel, then what is the purpose of this patch?
