From 81caaf2503be8fbb738ea4f124063dcc24958397 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 5 Mar 2012 23:29:51 +0000 Subject: ARM: ecard: ensure fake vma vm_flags is setup Our TLB ops want to check the vma vm_flags to find out whether the mapping is executable. However, we leave this uninitialized in ecard.c. Initialize it with an appropriate value.
