	Actual code let compiler generates idiv instruction on x86. Using a right shift is OK here and readable as well.

2006-02-10	[PATCH] powerpc: trivial: modify comments to refer to new location of files	Jon Mason
	This patch removes all self references and fixes references to files in the now defunct arch/ppc64 tree. I think this accomplises everything wanted, though there might be a few references I missed. Signed-off-by: Jon Mason <jdmason@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-04-16	Linux-2.6.12-rc2v2.6.12-rc2	Linus Torvalds
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
