Subject: [PATCH] arch/powerpc/mm: Enable compound page check for both THP and HugeTLB
Date: Fri, 20 Mar 2020 16:02:56 +0530	[thread overview]
Message-ID: <20200320103256.229365-1-aneesh.kumar@linux.ibm.com> (raw)

THP config can result in compound pages. Make sure kernel enables the
PageCompound() check when only THP is enabled.
