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

[Punit Agrawal <punit.agrawal@arm.com>]

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
