From: David Daney Date: Thu, 28 May 2009 00:47:46 +0000 (-0700) Subject: MIPS: Kconfig Add SYS_SUPPORTS_HUGETLBFS and enable it for some systems. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9cffd154cf6817b130762501b91e753524ba2cd4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
