MIPS: Kconfig Add SYS_SUPPORTS_HUGETLBFS and enable it for some systems.
Add new kconfig variables SYS_SUPPORTS_HUGETLBFS and CPU_SUPPORTS_HUGEPAGES. They are enabled for systems that are known to support huge pages. Signed-off-by: David Daney <ddaney@caviumnetworks.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
