Just updated the Raspberry Pi to kernel version 3.7.5, using the 3.7.1 tree created by Olipro:
I then applied the incremental patches from kernel.org to go from 3.7.1 to 3.7.2, to 3.7.3, to 3.7.4, to 3.7.5..
I ignored the warnings after the compile, as these have occurred with previous kernel versions, and seem to be harmless..
And everything seems to be working OK, so far:
Fedora release 18 (Spherical Cow)
Kernel 3.7.5-pi on an armv6l (ttyAMA0)
$ uname -a
Linux rgpi 3.7.5-pi #1 Mon Jan 28 14:30:38 GMT 2013 armv6l armv6l armv6l GNU/Linux
Update: The test .config I used is at http://pastebin.com/ZFKG5Mm6 This is only for testing, and may not have all the peripheral options selected, but it does work!
