From 59438c9fc4f7a92c808c9049bc6b396f98bf954c Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Mon, 21 Jul 2008 22:59:42 -0700 Subject: x86: rename PTE_MASK to PTE_PFN_MASK Rusty, in his peevish way, complained that macros defining constants should have a name which somewhat accurately reflects the actual purpose of the constant. Aside from the fact that PTE_MASK gives no clue as to what's actually being masked, and is misleadingly similar to the functionally entirely different PMD_MASK, PUD_MASK and PGD_MASK, I don't really see what the problem is. But if this patch silences the incessent noise, then it will have achieved its goal (TODO: write test-case).
