Hello, I have done build tests for ARCH=arm on 2.6.31.12-rt20 and to fix most platforms I needed to cherry pick three commits from post-2.6.31 mainline: 9fd868f ([WATCHDOG] davinci: use clock framework for timer frequency) b9696ea (net: Fix IXP 2000 network driver building.) 0bfb34f (ARM: S3C2440: mini2440: Fix missing CONFIG_S3C_DEV_USB_HOST) (One of these fails to cleanly apply on top of 2.6.31.12-rt20 so I made them available at git://git.pengutronix.de/git/ukl/linux-2.6.git rt/arm based on tip/rt/arm). Then there is a problem with highmem (only on ARM). A fix was discussed already earlier, but as there havn't been anyone volunteering to test it, Thomas didn't take it. As I don't have a machine needing highmem I cannot test either. So I just resend it as it changed slightly since the last post to keep it in the archives (or for the case Thomas wants to take it now). It's available at git://git.pengutronix.de/git/ukl/linux-2.6.git rt/highmemfix basing on the oldest commit having v2.6.31.7~101 and a7a08ef below .31.12-rt20. I'll send it as a reply to this mail, too. This only leaves a single defconfig broken that I havn't investigated yet.
