To be consistent with the use of attributes in the rest of the kernel
replace all use of __attribute_pure__ with __pure and delete the definition
of __attribute_pure__.

dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized
cache managment API for I/O purposes. Originally it was basically the raw
MIPS low level cache API exported to the entire world. The API has
suffered from a lack of documentation, was not very widely used unlike it's
more modern brothers and can easily be replaced by dma_cache_sync. So
remove it rsp. turn the surviving bits back into an arch private API, as
discussed on linux-arch.

Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on
32bit targets.
GCC can be made to warn about usage of long long types with ISO C90
(-ansi), but only with -pedantic. You can write this in a way that even
then it doesn't cause warnings, namely by:
#ifdef __GNUC__
__extension__ typedef __signed__ long long __s64;
__extension__ typedef unsigned long long __u64;
#endif
The __extension__ keyword in front of this switches off any pedantic
warnings for this expression.

DECLARE_MUTEX_LOCKED was used for semaphores used as completions and we've
got rid of them. Well, except for one in libusual that the maintainer
explicitly wants to keep as semaphore. So convert that useage to an
explicit sema_init and kill of DECLARE_MUTEX_LOCKED so that new code is
reminded to use a completion.

Input: ucb1400_ts - use schedule_timeout_uninterruptible
Input: xpad - fix dependancy on LEDS class
Input: auto-select INPUT for MAC_EMUMOUSEBTN option
...
Resolved conflicts manually in drivers/hwmon/applesmc.c: converting from
a class device to a device and converting to use input-polldev created a
few apparently trivial clashes..
This is the driver for latest Blackfin on-chip nand flash controller
- use nand_chip and mtd_info common nand driver interface
- provide both PIO and dma operation
- compiled with ezkit bf548 configuration
- use hardware 1-bit ECC
- tested with YAFFS2 and can mount YAFFS2 filesystem as rootfs
ChangeLog from try#1
- use hweight32() instead of count_bits()
- replace bf54x with bf5xx and BF54X with BF5XX
- compare against plat->page_size in 2 cases when enable hardware ECC
ChangeLog from try#2
- passed nand_test suites
- use cpu_relax() instead of busy wait loop
- some coding style issue pointed out by Andrew

When compiling the Blackfin kernel, checksyscalls.pl will report lots of missing syscalls warnings.
This patch will add some missing syscalls which make sense on Blackfin arch

- change default NMI handler to simply dump hardware trace buffer.
