From 02fcb974369d21c3df61d4ac5a2e1a58dce86495 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 21 Jun 2006 14:44:52 +0100 Subject: [ARM] Remove the __arch_* layer from uaccess.h Back in the days when we had armo (26-bit) and armv (32-bit) combined, we had an additional layer to the uaccess macros to ensure correct typing. Since we no longer have 26-bit in this tree, we no longer need this layer, so eliminate it.
