*_HUGE_SHIFT, *_HUGE_2MB, *_HUGE_1GB are documented in the man page, so add all of the *_HUGE_* macros from linux uapi. if MAP_HUGETLB is set, top bits of the mmap flags encode the page size. see the linux commit aafd4562dfee81a40ba21b5ea3cf5e06664bc7f6 if SHM_HUGETLB is set, top bits of the shmget flags encode the page size. see the linux commit 4da243ac1cf6aeb30b7c555d56208982d66d6d33 *_HUGE_16GB is defined unsigned to avoid signed left shift ub.
