* 'for-linus' of master.kernel.org:/pub/scm/linux/kernel/git/cooloney/blackfin-2.6:
Input Serio: Blackfin doesnt support I8042 - make sure it doesnt get selected
Blackfin arch: add BF54x I2C/TWI TWI0 driver support
Blackfin On-Chip RTC driver update for supporting BF54x
Blackfin Ethernet MAC driver: fix bug Report returned -ENOMEM upwards (in case L1/uncached memory alloc fails)
Blackfin arch: add error message when IRQ no available
Blackfin arch: Initialize the exception vectors early in the boot process
Blackfin arch: fix a compiling warning about dma-mapping
Blackfin arch: switch to using proper defines this time THREAD_SIZE and PAGE_SIZE instead of just PAGE_SIZE everywhere
Blackfin arch: fix bug which unaligns the init thread's stack and causes the current macro to fail.
Blackfin arch: Load P0 before storing through it
Blackfin arch: fix KGDB bug, dont forget last parameter.
Blackfin arch: add selections for BF544 and BF542
Blackfin arch: use bfin_read_SWRST() now that BF561 provides it
Blackfin arch: setup aliases for some core Core A MMRs
