From 8569c9140bd41089f9b6be8837ca421102714a90 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Sun, 17 Aug 2008 13:48:37 -0400 Subject: x86, um: take arch/um/include/* out of the way We can't just plop asm/* into it - userland helpers are built with it in search path and seeing asm/* show up there suddenly would be a bad idea.
