Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: (85 commits) Blackfin char driver for Blackfin on-chip OTP memory (v3) Blackfin Serial Driver: fix bug - use mod_timer to replace only add_timer. Blackfin Serial Driver: the uart break anomaly has been given its own number, so switch to it Blackfin Serial Driver: use BFIN_UART_NR_PORTS to help SIR driver in uart port. Blackfin Serial Driver: Fix bug - kernel hangs when accessing uart 0 on bf537 when booting u-boot and linux on uart 1 Blackfin Serial Driver: punt unused lsr variable Blackfin Serial Driver: Enable IR function when user application (irattach /dev/ttyBFx -s) call TIOCSETD ioctl with line discipline N_IRDA [Blackfin] arch: add include/boot .gitignore files [Blackfin] arch: Functional power management support: Add support for cpu frequency scaling [Blackfin] arch: Functional power management support: Remove broken cpu frequency scaling drivers [Blackfin] arch: Equalize include files: Add PLL_DIV Masks [Blackfin] arch: Add a warning about the value of CLKIN. [Blackfin] arch: take DDR DEVWD into consideration as well for BF548 [Blackfin] arch: Remove the circular buffering mechanism for exceptions [Blackfin] arch: lose unnecessary dependency on CONFIG_BFIN_ICACHE for MPU [Blackfin] arch: fix bug - before assign new channel to the map register, need clear the bits first. [Blackfin] arch: add Blackfin on-chip SIR IrDA driver support [Blackfin] arch: BF54x memsizes are in mbits, not mbytes [Blackfin] arch: try to remove condition that causes double fault, by checking current before it gets dereferenced [Blackfin] arch: Update anomaly list. ...
