From d8fd35fc586f74b2defe011d3a2bfb507871a407 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Fri, 18 May 2012 20:01:16 +0900 Subject: [PATCH] sh64: Fix up vmalloc fault range check. With the previous attempt reverted this switches to conditionalizing the end address. Nominally VMALLOC_END, but extended for P3_ADDR_MAX in the store queue case.
