From 2c3c0693d9cf06d7baf99cfdc10f9c4d40198c6b Mon Sep 17 00:00:00 2001 From: Li Zhong Date: Mon, 15 Apr 2013 16:53:18 +0000 Subject: [PATCH] powerpc: Move the setting of rflags out of loop in __hash_page_huge It seems that new_pte and rflags don't get changed in the repeating loop, so move their assignment out of the loop.
