From 7391e259a1d29672de29364be76ef26ca6e48494 Mon Sep 17 00:00:00 2001 From: Tony Liu Date: Wed, 18 Aug 2010 15:16:56 +0800 Subject: [PATCH] cramfs xip: pass virtual address to do flush tlb The parameter addr of flush_tlb_page() should be user virtual address of address space 'vma->vm_mm'. But here, obviously the address for it is physical address of NOR flash partition shipping CRAMFS XIP rootfs. Correct it to it's mapping virtual address.
