Lazy page table copying at fork time was introduced with commit
d992895ba2b2 ("[PATCH] Lazy page table copies in fork()"). At the
time, hugetlb was very new and did not support page faulting. As a
result, it was excluded. When full page fault support was added for
hugetlb, the exclusion was not
At unmap, fork and remap time hugetlb address ranges are linearly
scanned. We can optimize these scans if the ranges are sparsely
populated.
Also, enable page table "Lazy copy" for hugetlb at fork.
NOTE: Architectures not defining CONFIG_ARCH_WANT_GENERAL_HUGETLB

As an optimization for loops sequentially processing hugetlb address
ranges, huge_pmd_unshare would update a passed address if it unshared a
pmd. Updating a loop control variable outside the loop like this is
generally a bad idea. These loops are now using hugetlb_mask_last_page

From: Baolin Wang
The HugeTLB address ranges are linearly scanned during fork, unmap and
remap operations, and the linear scan can skip to the end of range mapped
by the page table page if hitting a non-present entry, which can help
to speed linear scanning of the HugeTLB address ranges.
So huge
HugeTLB address ranges are linearly scanned during fork, unmap and
remap operations. If a non-present entry is encountered, the code
currently continues to the next huge page aligned address. However,
a non-present entry implies that the page table page for that entry
is not present. Therefore,

The platform's RNG must be available before random_init() in order to be
useful for initial seeding, which in turn means that it needs to be
called from setup_arch(), rather than from an init call. Fortunately,
