This moves the uc_sigmask field back to where it was before.  We now don't
assume the registers are at a fixed offset in the ucontext, but instead
access them through the uc_regs field as in the past.  This corresponds with
a recent change in glibc CVS.

From: Douglas Gilbert <dougg@torque.net>

Attached is an update of the scsi_mid_low_api text
document. The first attachment is a gzipped patch against
lk 2.6.0-test4 and the second one is the file gzipped.

Changes:
   - add "Calling context:" entry to interface functions
   - add "Might block:" entry to mid level functions
   - drop scsi_set_device_offline() + command()
   - change references to reflect transfer of headers to
     include/scsi/scsi_*.h
   - try to define what a "scsi host" is
   - typos + grammar

Thanks to Randy Dunlap, Alan Stern amd Christoph Hellwig
for their input. Comments welcome.

GCC 3.4 miscompiles the kernel because it silently optimizes away
data placed in the .init.setup section by the __setup() macro.

__attribute__((unused)) does only avoid the warning, but doesn't
mark the data as being used.

Since GCC 3.3, __attribute__((used)) should be applied to such
variables.  The __attribute_used__ macro from linux/compiler.h already
takes care of compiler differences for us.

In this patch, I've gone a step further and proactively fixed that in
all places.

Thanks Matt and Jens for the debug help on the multipath problem. 

This solves the problem and makes multipath work properly.

There are two types of "flags" that are used in a block io request,
bi_flags, and bi_rw.  bi_flags is used for flags to the block level
code, and bi_rw is used for flags to the low level device drivers.

The code in the multipath driver used the wrong flag in the wrong field.
In this case, the flag FASTFAIL (value 3) was being set to the bi_flags
field.  FASTFAIL is a hint to the low level driver that it should try to
fail out quickly.  Unfortunately, the value 3 is also BIO_SEG_VALID,
which is a flag to the block subsystem that the segments shouldn't be
recalculated.  The result was that the wrong field was set, telling the
block layer not to recalculate the segments resulting in phys and hw
segments of 0.  Not good.

This is a new patch that includes Martin's, and makes create_dir() return
an int. That matches sysfs_create_file(), and saves a couple of
conversions back and forth between pointer and error.

It's not like it would compile without PCI support anyway, and these
ifdefs are _really_ strange.

Same issues as the dma mapping code, but as SN2 interrupt handling is
totally static and all irqs are allocated on bootup an never freed it's
not a speed issue.

I really wonder what someone has to smoke to call a that expensive
dispatcher just to cast the data structure back to the lowlevel one
directly afterwards...

fed through Lindent and dead codepathes eliminated.

Currently the the SN2 dma mapping code uses a file systen lookup (cat /r/napali/tmp/p10 |diffstat -p1) to
find the operation vector for the underlying dma mapping implementation.

But not only there is exactly one of those implementation, also data
structures from this lowlevel driver are used in the actual Linux dma
mapping routines and quite a few assumption are made about it.  So let's
just call directly in the lowlevel code and give up this utter bullshit.

These strange mixups of Linux and IRIX PCI interfaces were used in SGI's
2.4 tree for their port of the IRIX scsi code.  They have no business to
stgay in 2.6.

More IRIX creepism

Just some crappy stubs that sneaked over from IRIX.

Keith shared my opionion that it's completly useless.  Also everyone
seems to favour keeping kdb stuff out of mainline.

	up the leftovers.

	by a module, even more the file doesn't compile when
	CONFIG_IA64_SGI_SN_DEBUG is set.

	the current tree.

Duh!  The scsi_cmnd.flags removal broke qla1280.

It checked for the flags beeing 0, which it always was for a long
time.  It looks a bit fishy thus, so if someone wants to audit
srb.flags audit please do so.
