Linux-2.6.12-rc2 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! 2005-04-16 15:20:36 -07:00			`/*`

[ARM] Remove RETINSTR macro RETINSTR is a left-over from the days when we had 26-bit and 32-bit CPU support integrated into the same tree. Since this is no longer the case, we can now remove RETINSTR. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> 2006-06-25 11:17:23 +01:00			`mov pc, lr`
