fix a bunch of race conditions and locking bugs in video and vbi capture
code on device closure

use vmalloc_32() instead of vmalloc() in saa7146_vmalloc_build_pgtable().
this makes sure that the pagetable is in lowmem kernel memory

i2c timeout fix by Gerd Knorr 

SAA7146_I2C_SHORT_DELAY flag to speed up I2C access by Oliver Endriss

move saa7146_set_gpio() from saa7146_vv to saa7146_core, it's needed by DVB
budget drivers

add "new" saa7146_wait_for_debi_done() function, remove other versions from
av7110 and budget.ci

make budget-ci use this gpio function and the new wait_...() function,

make saa7146_pgtable_build_single() deliver a return code, make sanity
checks of the arguments

sanitize enabling of video input pins and i2c pins, use some default
values, so the hardware is always in a sane state

remove SAA7146_EXT_SWAP_ODD_EVEN flag + handling, fix the hardware
initialization instead

change minimal picture size to 48x32 just like other drivers

set up arbitrition control for video dma3 correctly

remove unnecessary code for capture to framebuffer memory, it's handled in
the generic code

The "make rpm" rule in top Makefile isn't aware of the enviorment ARCH.  For
example, people issue "make ARCH=ia64" to compile the ia64 kernel on i386
platform for cross compilation.  This works pretty well now.  But if one uses
"make rpm ARCH=ia64", it will fail.  Because current rpm rule in Makefile and
mkspec are not aware of ARCH.

The attached patch adds support for suspend/resume to the sis900 driver.
With this patch on resume the NIC is fully configured and operational,
before a module reload was needed because of the complete lack of
suspend/resume callbacks.

I added two functions, sis900_suspend and sis900_resume, with their
pointers in struct pci_driver. A vector of 16 u32 was then needed to the
to keep PCI data during suspend. I added it in struct sis900_private.
I updated the revision number to reflect my changes. 
Looking at the code I also killed three typos.

The patch doesn't touch any other code.

Since I don't know anything on ethernet drivers the rule 'works for me'
is fully valid.

The dm table size is always known in advance, so we can specify it in

When we register disks, we mangle the disk names that contain slashes (e.g.
cciss/c0d0) replacing them with '!' in corresponding sysfs names.  So
name_to_dev_t() should mangle the name in the same way before looking for it
in /sys/block.

Entirely revised, and largely rewritten.  Has a continuing example now, which

I've seen this patch floating around.  Not sure the origin, but it's 
surfaced on lkml and also when I was poking around handhelds.org CVS for
iPAQ patches:  on non-PCs, particularly system-on-chip devices but not
just there, you have a custom "platform bus" that is the root of pretty 
much all other devices and buses.

It's something I wanted to make sure people didn't forget; to make sure 
the legacy_bus didn't get "legacied out of existence."  ;-)

I believe I have identified a failure mode that Linus saw a couple weeks
back when tracking down some other fork/exit sorts of races.  We saw this
come up on rare occasions with the RHEL3 kernel's backport of the new code
(while trying to track down other race failure modes we have yet to fix, sigh).

I am talking about the following scenario:

What happens here is a race between an exiting thread checking
mm->core_waiters in __exit_mm, and the thread taking the core-dump signal
(in coredump_wait) examining the first thread's ->mm pointer and
incrementing mm->core_waiters to account for it.  There is no
synchronization at all in __exit_mm's use of mm->core_waiters.  If the
coredump_wait thread reads tsk->mm when tsk is in __exit_mm between
checking mm->core_waiters and clearing tsk->mm, then it will increment
mm->core_waiters and the total count will later exceed the number of
threads that will ever decrement it and synchronize.  Hence it blocks forever.

The following patch fixes the problem by using mm->mmap_sem in __exit_mm.
The read lock must be held around checking mm->core_waiters and clearing
tsk->mm so that coredump_wait (which gets the write lock) cannot come in
between and do bogus bookkeeping.

Here's a patch that changes the DAC960 driver from having one request
queue for ALL disks on the controller, to having a request queue for
each logical disk.  This turns out to make little difference for deadline
scheduler, nor for AS scheduler under light IO load.  But under AS
scheduler with heavy IO, it makes about a 40% difference on dbt2
workload.  Here are the measured numbers:

The 2.6.0-test11-D kernel version includes this mutli-queue patch to the
DAC960 driver.

For non-cached dbt2 workload  (heavy IO load)

Scheduler	kernel/driver	NOTPM(bigger is better)
AS		2.6.0-test11-D  1598
AS		2.6.0-test11     973
deadline	2.6.0-test11    1640
deadline	2.6.0-test11-D  1645

For cached dbt2 workload (lighter IO load)

AS		2.6.0-test11-D  4993
AS		2.6.-test6-mm4  4976, 4890, 4972
deadline	2.6.0-test11-D  4998

Can this be included in 2.6.0?  I know it's not a "critical patch"
in the sense that something won't work without it.  On the other hand,
the change is isolated to a driver.

A previous "cleanup" on the nbd.h header file broke userspace compiles.
I've added an #ifdef __KERNEL__ so that userspace doesn't need to worry
about the nbd_device structure, which is only used in-kernel. The patch
allows me to compile my nbd tools with the 2.6 nbd.h.
