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: (56 commits)
Blackfin arch: fix bug when enable uart1 with uart0 disabled => no initial console
Blackfin arch: split apart dump_bfin_regs and merge/remove show_regs from process.c, which was largely duplicated
Blackfin arch: use common __INIT/__FINIT defines rather than setting the .section ourselves to .init.text
Blackfin arch: fix bug when sending signals with the wrong PC, cause gdb get confused
Blackfin arch: Ensure we printk out strings with the proper loglevel
Blackfin arch: Need to specify ax with the .init.text section,
Blackfin arch: Update Kconfig to latest Blackfin silicon datasheets
Blackfin arch: update defconfig files
Blackfin arch: Fix typo, and add ENDPROC - no functional changes
Blackfin arch: convert READY to DMA_READY as it causes build errors in common sound code otherwise
Blackfin arch: add defines for the on-chip L1 ROM of BF54x
Blackfin arch: cplb and map header file cleanup
Blackfin arch: cleanup the cplb declares
Blackfin arch: fix broken on BF52x, remove silly checks on processors for L1_SCRATCH defines
Blackfin arch: add support for working around anomaly 05000312
Blackfin arch: cleanup BF54x header file and add BF547 definition
Blackfin arch: fix building for BF542 processors which only have 1 TWI
Blackfin arch: rename _return_from_exception to _bfin_return_from_exception and export it
Blackfin arch: move EXPORT_SYMBOL() to C files where the symbol is actually defined
Blackfin arch: fix bug NOR Flash MTD mount fail

('port'). Once you have done that, you will be able to use
parport_claim and parport_release in order to use the port.
+The ('name') argument is the name of the device that appears in /proc

This function will register three callbacks into your driver:
'preempt', 'wakeup' and 'irq'. Each of these may be NULL in order to
indicate that you do not want a callback.

+On IBM (and some of the earlier Lenovo) ThinkPads, the backlight control

+from 0 to 15.
-There are two interfaces to the firmware for brightness control, EC and CMOS.
-To select which one should be used, use the brightness_mode module parameter:

+When display backlight brightness controls are available through the
+standard ACPI interface, it is best to use it instead of this direct
+ThinkPad-specific interface. The driver will disable its native
+backlight brightness control interface if it detects that the standard
+ACPI interface is available in the ThinkPad.
+
+The brightness_enable module parameter can be used to control whether
+the LCD brightness control feature will be enabled when available.
+brightness_enable=0 forces it to be disabled. brightness_enable=1
+forces it to be enabled when available, even if the standard ACPI
