From 024b246ed24492d6c2ee14c34d742b137fce1b94 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Fri, 15 Aug 2008 09:19:40 -0700 Subject: alpha: move include/asm-alpha to arch/alpha/include/asm Sam Ravnborg did the build-test that the direct header file move works, I'm just committing it. This is a pure move: mkdir arch/alpha/include git mv include/asm-alpha arch/alpha/include/asm with no other changes.
