One small-ish comment about 0002: there is no need to add the unit
into the buffer set as GUC_UNIT_MB would take care of that. The patch
looks fine.

So, this is needed in ipci.c to check for MAP_HUGETLB. I am not much
a fan of moving around platform-specific checks when these have
remained local to each shmem implementation. Could it be cleaner to
add GetHugePageSize() to win32_shmem.c and make it always declared in
the SysV implementation?
