From e39155ea11eac6da056b04669d7c9fc612e2065a Mon Sep 17 00:00:00 2001 From: "Kirill A. Shutemov" Date: Wed, 15 Apr 2015 16:14:53 -0700 Subject: mm: uninline and cleanup page-mapping related helpers Most-used page->mapping helper -- page_mapping() -- has already uninlined.

It saves us depending on configuration around 400 bytes in text: text data bss dec hex filename 660318 99254 410000 1169572 11d8a4 mm/built-in.o-before 659854 99254 410000 1169108 11d6d4 mm/built-in.o I also tried to make code a bit more clean.
