Subject: [PATCH v5 0/8] Support for contiguous pte hugepages

Hi Andrew,

This is v5 of the patchset to update the hugetlb code to support
contiguous hugepages. Previous version of the patchset can be found at
[0].

The main changes in this version are updating Patch 4 and 7 due to
issues highlighted in the previous postings (ltp and build failure).

Please update the patches in your queue with this version.

Thanks,
Punit

Changes since v4:

* Patch 4 updated to fix arm64 ltp failure (pth_str01, pth_str03) [1]
* Patch 7 update to fix build failure when CONFIG_HUGETLB_PAGE is disabled
