Merge branch 'master' of master.kernel.org:/pub/scm/linux/kernel/git/cooloney/blackfin-2.6
* 'master' of master.kernel.org:/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: (30 commits) Blackfin SMC91X ethernet supporting driver: SMC91C111 LEDs are note drived in the kernel like in uboot Blackfin SPI driver: fix bug SPI DMA incomplete transmission Blackfin SPI driver: tweak spi cleanup function to match newer kernel changes Blackfin RTC drivers: update MAINTAINERS information Blackfin serial driver: decouple PARODD and CMSPAR checking from PARENB Blackfin serial driver: actually implement the break_ctl() function Blackfin serial driver: ignore framing and parity errors Blackfin serial driver: hook up our UARTs STP bit with userspaces CMSPAR Blackfin arch: move HI/LO macros into blackfin.h and punt the rest of macros.h as it includes VDSP macros we never use Blackfin arch: redo our linker script a bit Blackfin arch: make sure we initialize our L1 Data B section properly based on the linked kernel Blackfin arch: fix bug can not wakeup from sleep via push buttons Blackfin arch: add support for Alon Bar-Lev's dynamic kernel command-line Blackfin arch: add missing gpio.h header to fix compiling in some pm configurations Blackfin arch: As Mike pointed out range goes form m..MAX_BLACKFIN_GPIO -1 Blackfin arch: fix spelling typo in output Blackfin arch: try to split up functions like this into smaller units according to LKML review Blackfin arch: add proper ENDPROC() Blackfin arch: move more of our startup code to .init so it can be freed once we are up and running Blackfin arch: unify differences between our diff head.S files -- no functional changes ...
