Subject: [PATCH] powerpc/mm: Fix hugetlb page initialization
Date: Mon, 06 May 2019 17:33:33 +0530 [thread overview]
Message-ID: <20190506120328.4079.85660.sendpatchset@Sachins-MacBook-Pro.local> (raw)
This patch fixes a regression by using correct kernel config variable
for HUGETLB_PAGE_SIZE_VARIABLE.
Without this huge pages are disabled during kernel boot.
[0.309496] hugetlbfs: disabling because there are no supported hugepage sizes
Fixes: c5710cd20735 ("powerpc/mm: cleanup HPAGE_SHIFT setup")
