Subject: [PATCH] selftests/thuge-gen: Use platform specific MAP_HUGETLB value
Date: Thu, 31 Mar 2016 13:11:05 +0200	[thread overview]
Message-ID: <20160331111105.GA30888@p100.box> (raw)

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

Tested with a parisc architecture 64bit kernel.
