are handled by other properties; but instead of accessing those

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
to optimize
Lazy page table copying at fork time was introduced with commit
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
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
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,
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.

Hi,
Update: checking out 'dmesg' more carefully I found out that the module probe
is failing with the following message:
[ 186.298424][ T811] pseries-wdt: probe of pseries-wdt.0 failed with error -5
This fail is consistent. If I remove the module and modprobe it again the same
error happens.

Don't worry about 'fpga_np==NULL' as of_node_put() can correctly
handle it.
