We now use the sir_dev/irtty_sir/uart/bfin_serial drivers framework
to monitor the TX status.

move common variables out of serial headers and into the serial driver and
rename "nr_ports" to "nr_active_ports" so as to easily differentiate
between BFIN_UART_NR_PORTS (the # of available) and nr_ports (the # of enabled)

Using just 'unsigned' will make flags an unsigned int. While this is
arguably not an error on blackfin where sizeof(int) == sizeof(long),
the patch is still justified on the grounds of principle.
The patch was generated using the Coccinelle semantic patch framework.

AFAIR there exists blackfin hardware with PCI support, but the support
currently in the kernel fails to build starting with:
...
CC drivers/pci/probe.o
probe.c: In function 'pci_scan_slot':
probe.c:1056: error: implicit declaration of function 'pcibios_scan_all_fns'
make[3]: *** [drivers/pci/probe.o] Error 1

- remove cheesy read_iloc() function
- move invalidate_entire_icache function to lock.S
- export proper prototypes for functions in lock.S
- only build lock.S when BFIN_ICACHE_LOCK is enabled

as pointed out by Michael McTernan in the forums, when expanding
the trace buffer, it does not print out the decoded instruction.

- Disable all bits in SIC_IWR unless we are going into a real (DPMC)
power saving mode. Any Interrupt can wake the core form it's idle state.
- Remove deep sleep mode as it is not going to be used anywhere:
We support sleep, sleep deeper and hibernate.

- Skip single step if global interrupt disable bit is set.
- Extend bernds' patch r4673 to skip single step in any interrupt entry
that interrupts the code which is under single stepping. Bernds' patch
only allow user space single stepping.

these are highly board specific, so putting into generic doesnt make much sense

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: (30 commits)
Blackfin arch: If we double fault, rather than hang forever, reset
Blackfin arch: When icache is off, make sure people know it
Blackfin arch: Fix bug - skip single step in high priority interrupt handler instead of disabling all interrupts in single step debugging.
Blackfin arch: cache the values of vco/sclk/cclk as the overhead of doing so (~24 bytes) is worth avoiding the software mult/div routines
Blackfin arch: fix bug - IMDMA is not type struct dma_register
Blackfin arch: check the EXTBANKS field of the DDRCTL1 register to see if we are using both memory banks
Blackfin arch: Apply Bluetechnix CM-BF527 board support patch
Blackfin arch: Add unwinding for stack info, and a little more detail on trace buffer
Blackfin arch: Add ISP1760 board resources to BF548-EZKIT
Blackfin arch: fix bug - detect 0.1 silicon revision BF527-EZKIT as 0.0 version
Blackfin arch: add missing IORESOURCE_MEM flags to UART3
Blackfin arch: Add return value check in bfin_sir_probe(), remove SSYNC().
Blackfin arch: Extend sram malloc to handle L2 SRAM.
Blackfin arch: Remove useless config option.
Blackfin arch: change L1 malloc to base on slab cache and lists.
Blackfin arch: use local labels and ENDPROC() markings
Blackfin arch: Do not need this dualcore test module in kernel.
Blackfin arch: Allow ptrace to peek and poke application data in L1 data SRAM.
Blackfin arch: Add ANOMALY_05000368 workaround
Blackfin arch: Functional power management support
...
Remove arch-specific show_mem() in favor of the generic version.
This also removes the following redundant information display:
- free pages, printed by show_free_areas()
- pages in swapcache, printed by show_swap_cache_info()
where show_mem() calls show_free_areas(), which calls
show_swap_cache_info().
