Re: [PATCH 2/6] mm: Generalize SYS_SUPPORTS_HUGETLBFS (rename as ARCH_SUPPORTS_HUGETLBFS)

Anshuman Khandual [off-list ref] writes:

SYS_SUPPORTS_HUGETLBFS config has duplicate definitions on platforms that
subscribe it. Instead, just make it a generic option which can be selected
on applicable platforms. Also rename it as ARCH_SUPPORTS_HUGETLBFS instead.
This reduces code duplication and makes it cleaner.
