Subject: Hugetlbfs: Enable hugetlbfs for more systems in Kconfig.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=852969b2d273e77dabbc22e1c1058cbafb7ad7d2;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Hugetlbfs: Enable hugetlbfs for more systems in Kconfig.

As part of adding hugetlbfs support for MIPS, I am adding a new
kconfig variable 'SYS_SUPPORTS_HUGETLBFS'.  Since some mips cpu
varients don't yet support it, we can enable selection of HUGETLBFS on
a system by system basis from the arch/mips/Kconfig.
