From: Li Wang <[email protected]>
When testing on ppc64 arch, `./hugemmap03 -s 64` failed message as:
hugemmap03 1 TFAIL : mmap into high region failed unexpectedly
- expect errno=ENOMEM, got: errno=EINVAL(22): Invalid
But it is not the system issue, MMAP(2) Programmer's Manual define the
mmap() error return value like:
EINVAL We don't like addr, length, or offset (e.g., they are too
large, or not aligned on a page boundary).
ENOMEM No memory is available, or the process's maximum number of
mappings would have been exceeded.
So, we should consider the EINVAL return situation on ppc64.
