From: Kirill A. Shutemov Date: Tue, 10 Feb 2015 22:10:39 +0000 (-0800) Subject: m32r: drop _PAGE_FILE and pte_file()-related helpers X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=406b16e26d0996516c8d1641008a7d326bf282d6;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git m32r: 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.
