-Subject: [PATCH] ARM: Don't extend bit LG_VADDR to compute high address bits.
-
-In userspace ARM on Linux, zero-ing the high bits is the correct way to do this.
-This doesn't fix the fact that we currently set LG_VADDR to 48 on ARM, when in
-fact larger virtual address sizes are coming soon.  We'll cross that bridge when
-we come to it.
