* git://git.kernel.org/pub/scm/linux/kernel/git/czankel/xtensa-2.6: xtensa: Add config files for Diamond 232L - Rev B processor variant xtensa: Fix io regions xtensa: Add support for the Sonic Ethernet device for the XT2000 board. xtensa: replace remaining __FUNCTION__ occurrences xtensa: use newer __SPIN_LOCK_UNLOCKED macro XTENSA: warn about including <asm/rwsem.h> directly.
