From 1c2f7d14d84f767a797558609eb034511e02f41e Mon Sep 17 00:00:00 2001 From: Anshuman Khandual Date: Wed, 30 Jun 2021 18:53:59 -0700 Subject: mm/thp: define default pmd_pgtable() Currently most platforms define pmd_pgtable() as pmd_page() duplicating the same code all over. Instead just define a default value i.e pmd_page() for pmd_pgtable() and let platforms override when required via . All the existing platform that override pmd_pgtable() have been moved into their respective header in order to precede before the new generic definition. This makes it much cleaner with reduced code.
