From 758db3f2118703a1e36374dae5d58bed963e7e0d Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Wed, 13 Aug 2008 14:26:22 -0700 Subject: [h8300] move include/asm-h8300 to arch/h8300/include/asm Done as a script (well, a single "git mv" actually) on request from Yoshinori Sato as a way to avoid a huge diff.
