From d9ecee281b8f89da6d3203be62802eda991e37cc Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Tue, 10 Feb 2015 14:11:25 -0800 Subject: [PATCH] xtensa: drop _PAGE_FILE and pte_file()-related helpers We've replaced remap_file_pages(2) implementation with emulation. Nobody creates non-linear mapping anymore. Signed-off-by: Kirill A.
