From 734269521e320ad14ed39ae9b64d482b9028dcd2 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 20 Feb 2009 16:29:07 +0900 Subject: [PATCH] vmalloc: call flush_cache_vunmap() from unmap_kernel_range() Impact: proper vcache flush on unmap_kernel_range() flush_cache_vunmap() should be called before pages are unmapped. Add a call to it in unmap_kernel_range().
