From f078cd46de9efb5f102a4b32aaf1c8b96a90bfbd Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 12 Mar 2013 00:31:22 +0000 Subject: [PATCH] mmu-hash*: Remove eaddr field from mmu_ctx_hash{32, 64} The eaddr field of mmu_ctx_hash{32,64} is effectively just used to pass the effective address from get_segment{32,64}() to find_pte{32,64}(). Just pass it as a normal parameter instead.
