[Blackfin] arch: fix bug - trap_tests fails to recover on some tests.
http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3719
When the CPLBs get a miss, we do:
- find a victim in the HW table
- remove the victim
- find the replacement in the software table
- put it into the HW table.
If we can't find a replacement in the software table, we accidently
leave a duplicate in the HW table. This patch ensures that duplicate
is marked as not valid.
What we should do is find the replacement in the software table, before
we find a victim in the HW table - but its too late in the release cycle
to do that much restructuring of this code.
Rather that duplicate code, connect Hardware Errors (irq5) into trap_c,
so user space processes get killed properly.
The rest of irq_panic() can be moved into traps.c (later)
There is still a small corner case that causes problems when a
pheriperal interrupt goes off a single cycle before a user space
hardware error. This causes a kernel panic, rather than the user
space process being killed.
But, this checkin makes things work in 99.9% of the cases, and is a vast
improvement from what is there today (which fails 100% of the time).

In ide_taskfile_ioctl(), there was a race condition involving

So, other requests could execute with the altered ->io_32bit

ide: remove broken disk byte-swapping support
Remove broken disk byte-swapping support:
- it can cause a data corruption on SMP (or if using PREEMPT on UP)
- all data coming from disk are byte-swapped by taskfile_*_data() which
results in incorrect identify data being reported by /proc/ide/ and IOCTLs
- "hdx=bswap/byteswap" kernel parameter has been broken on m68k host drivers
(including Atari/Q40 ones) since 2.5.x days (because of 'hwif' zero-ing)
- byte-swapping is limited to PIO transfers (for working with TiVo disks on
x86 machines using user-space solutions or dm-byteswap should result in
much better performance because DMA can be used)

* Rename cris_dma_{on,off}() to cris_dma_host_{on,off}().
* Remove no longer needed ->dma_off_quietly
(IDE core has the needed code now).
* Make cris_dma_host_on() void.
I left fixing ide-cris after "kill dma_on/dma_off_quietly() methods"
patch because:
* Currently this driver is broken: cris_dma_on() (returns 'int')
is assigned to hwif->dma_host_on (returns 'void') so the driver
won't build.
* ->ide_dma_on method was missing so the driver OOPS-es on attempt
to enable DMA.
* drive->using_dma was never set/cleared so DMA wouldn't be used anyway.
Unfortunately it seems that ide-cris stays broken even after this patch:
* V10: <asm/arch-v10/ide.h> needs fixing
- ide_init_default_hwifs() should be removed
(IDE core no longer uses it)
- same for ide_init_hwif_ports() and ide_default_{irq,io_base}()
(they shouldn't be needed for ide-cris host driver)
* V32: I'm unable to find a place which defines ETRAX_ARCH_V32
but I'm leaving fixing this to CRIS gurus. :)

ide: remove ->ide_dma_on and ->dma_off_quietly methods from ide_hwif_t
* Make ide_dma_off_quietly() and __ide_dma_on() always available.
* Drop "__" prefix from __ide_dma_on().
* Check for presence of ->dma_host_on instead of ->ide_dma_on.
* Convert all users of ->ide_dma_on and ->dma_off_quietly methods
to use ide_dma_on() and ide_dma_off_quietly() instead.
* Remove no longer needed ->ide_dma_on and ->dma_off_quietly methods
from ide_hwif_t.
* Make ide_dma_on() void.
There should be no functionality changes caused by this patch.

au1xxx-ide: add ide_toggle_bounce() calls
Add ide_toggle_bounce() call to ->ide_dma_on/->dma_off_quietly
methods so they match generic __ide_dma_on()/ide_dma_off_quietly().
Since there is no PCI device there should be no functionality
changes caused by this patch.
