Date: Mon, 15 Jul 2019 17:40:03 -0400 From: Paul Cercueil <paul@...pouillou.net> To: Ralf Baechle <ralf@...ux-mips.org>, Paul Burton <paul.burton@...s.com>, James Hogan <jhogan@...nel.org> Cc: od@...c.me, linux-mips@...r.kernel.org, linux-kernel@...r.kernel.org, Daniel Silsby <dansilsby@...il.com>, Paul Cercueil <paul@...pouillou.net> Subject: [PATCH 5/5] MIPS: Undefine PMD_ORDER for 32-bit builds From: Daniel Silsby <dansilsby@...il.com> During an update long ago to conform to 4-level page code, PMD_ORDER was changed from 0 to 1, despite the fact that a PMD table is not used at all in a 32-bit MIPS build. PMD_ORDER does not seem to be used in these builds. Now, it matches PUD_ORDER, a nonsense #define to give a build failure with informative error. The older commit that had redefined PMD_ORDER was commit c6e8b587718c ("Update MIPS to use the 4-level pagetable code thereby getting rid of the compacrapability headers.")
