Hello Andrea, this commit:
commit 5d6892407cab23d4bf2f6de065ca351a53849323 Author: Andrea Arcangeli <aarcange@redhat.com> Date: Thu Jan 13 15:47:07 2011 -0800
thp: select CONFIG_COMPACTION if TRANSPARENT_HUGEPAGE enabled
causes this warning during the configuration process:
warning: (TRANSPARENT_HUGEPAGE) selects COMPACTION which has unmet direct dependencies (EXPERIMENTAL && HUGETLB_PAGE && MMU)
This happens because 'select' does not enable the dependencies of its target, so when I selected THP it also enabled COMPATION but I don't have HUGETLBFS (=HUGETLB_PAGE) enabled. Making THP select HUGETLB_PAGE fixes the warning but I'm not 100% sure that's correct (does it work without HUGETLBFS?).
Luca
