Subject: selftests/thuge-gen: Use platform specific MAP_HUGETLB value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a4351cb5511b917556c796d97068318a53a00849;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

selftests/thuge-gen: Use platform specific MAP_HUGETLB value

Do not hardcode MAP_HUGETLB to 0x40000, since quite some architectures
use a different value.

Tested with a parisc architecture 64bit kernel.
