From fd7e315988b784509ba3f1b42f539bd0b1fca9bb Mon Sep 17 00:00:00 2001 From: Tom Lendacky Date: Mon, 17 Jul 2017 16:10:06 -0500 Subject: x86/mm: Simplify p[g4um]d_page() macros MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit From: Tom Lendacky commit fd7e315988b784509ba3f1b42f539bd0b1fca9bb upstream. Create a pgd_pfn() macro similar to the p[4um]d_pfn() macros and then use the p[g4um]d_pfn() macros in the p[g4um]d_page() macros instead of duplicating the code.
