Patch from Maneesh Soni <maneesh@in.ibm.com>

It's supposed to return an ERR_PTR value on error, not NULL.

The loop driver takes a copy of the data which it is writing.  When this
happens on the try_to_free_pages() path, loop can easily consume ALL memory
and bio_copy() will fail to allocate a page.

Loop forgets to check the bio_copy() return value and oopses.

Fix this by dropping PF_MEMALLOC and throttling to the block writeout speed.

The patch exports blk_congestion_wait() to modules for this.  This is a
needed export: several filesystems have a "try to allocate and yield if it
failed" loop and blk_congestion_wait() is a more appropriate way of
implementing the sleep in this situation.

Patch from Nick Piggin <piggin@cyberone.com.au>

Closes a window in which we can get an invalid (already dispatched) request
in the next_drq cache.

This fixed an oops which was reported by Janet Morgan.

Patch from Anton Blanchard <anton@samba.org>

e100 is performing a header checksum calculation which is

a) duplication of the core kernel's calculation of the same and

b) incorrect on big-endian machines.

This fix has been tested on ia32 and pppc64 and acked by davem, jgarzik
and Scott Feldman

Fix socket memory mapping bug - we need to take account of the
requested card offset when returning the address for ioremap. 

Request PCMCIA socket resources without marking them busy - this
allows future modifications to pcmcia to allow it to claim the
CIS resources for statically mapped sockets.

Sanitise our pcmcia interrupt handling.  Make sure we only use
set_irq_type after the interrupt has been registered.

Register the socket handling interrupts using the function name
rather than some pointer passed by the generic code.

Let the generic sa11x0 code handle the cards interrupt masking.

Remove get_irq_info method, passing the information via the init
method instead.  The IRQ allocated to a socket never changes on
these platforms, so the extra code was just bloat.

Convert all SA11x0 drivers to register with the Linux driver model,
so they work with the pcmcia layer in 2.5.63.

Make low level socket_status() method take the socket index as an
argument in the same way that our other methods do.  socket_status()
now only returns the status of the requested socket, not all sockets.

Make low-level configure_socket() method take the socket number as
a parameter rather than embedded in a structure.

Make SA11x0 generic pcmcia implementation fit better with Dominik's
work - pass around our socket structure rather than the socket number
itself.  Reference socket operations using the socket structure
rather than a static variable.

You wouldn't expect that an innocent two-line patch would practically
destroy the entire functionality of the USB subsystem.  But that's what my
last patch did.  I didn't realize until I saw it in Greg's list of patches
forwarded to Linus; that patch includes a mistakenly unreverted prior
change.  This explains the problems I was having yesterday, and probably
also the problems a great many people are having today.

Anyway, here's the correction -- it puts things back to what they should
have been in the first place.  Greg, please apply this and send it to
Linus for his tree as soon as reasonably possible.

This is a temporary patch which should get cardbus working again.
In order to use pci_remove_behind_bridge(), we need to separately
allocate the pci_dev structures.

1) Define comma so dependency files does not include a '_' in the filename
2) Use correct path for mkspec and mkversion
3) Removed checkhelp - corresponding perl script is no longer present
4) Spelling correction (reported on lkml)

For some people (though not me), the '+' indicating that a command will
invoke a sub-make didn't propagated properly, and caused a warning.
Putting the command all into one line should fix that.

Plus some cosmetics and clean up the per_cpu check.

Alas no rave reviews on lkml, but the private feedback I have received so
far on the recent changes has been excellent. The Rhine-II is now finally
usable with via-rhine. Time to call it 1.17.

This trivial patch fixes an obvious typo. Please apply.

Bad semicolon in previous patch ([1/2]). Thanks to
Erik@harddisk-recovery.nl for spotting this.

update CPUfreq documentation, and move it to extra directory.

Update x86 drivers so that they can live with the new cpufreq governor
"userspace".

sparc64 doesn't need any change, and I'll send the corresponding patch
for ARM to Russell King.

The old /proc/sys/cpu/ - based interface is nothing else than a
cpufreq governor which decides what frequency to use within a policy
based on userspace input. So, convert this interface (and add a
corresponding sysfs file, /sys/devices/sys/cpu0/scaling_setspeed) to
become a cpufreq governor, and move it out to an extra module (which
partly explains the size of this patch).

- update the VIA Longhaul driver to use frequency table helpers and
  the advanced cpufreq driver registration interface.
- cleanup of the ACPI P-States cpufreq driver
- very small update of the core -- set 24API values ahead of the setpolicy
  call.

- switch the AMD Elan, AMD PowerNow-K6 and the Cyrix/MediaGX driver
  to use the advanced cpufreq_driver registration process
- cleanups

Fix an operator precedence bug that caused a comparison to always
return false. Patch from John Levon <levon@movementarian.org>.

Patch from Dave Hansen.

Fix simple bounding error found by some Stanford-checker type thing
to use the proper MAX_MP_BUSSES define instead of a constant.

This simple patch just makes sure the PIT code is available for NUMA-Q
(as its TSCs are not synced).

Has been tested in my tree for over a month on UP, SMP, and NUMA and
compile tested against a variety of different configs.

At the moment, there are two different switches used, irqbalance_disabled
and no_balance_irq ... each of which switches half the code off. This
patch harmonises them into one (irqbalance_disable), and uses the old
subarch stuff as a default value so that this is auto-disabled on boxes
like NUMA-Q that can't cope with it.

Also renamed no_balance_irq to NO_BALANCE_IRQ as it's really a static
defined number now, not pretending to be a switch variable any more.
Now off by default for NUMA-Q, on by default for others, but can be
disabled with the boot time flag if people desire.

Patch from Matthew Dobson

Provide a pcibus_to_cpumask function in the topology infrastructure to
access the pre-existing array.

Patch from William Lee Irwin

Inline and simplify pfn_to_nid - this is called heavily, it's a tiny
function, and makes a noticable difference in system time for kernel
compiles (sorry, lost the data). Is only used on NUMA machines.

Has been tested in my tree for over a month on UP, SMP, and NUMA and
compile tested against a variety of different configs.

translation_table could be unintialised on machines other than NUMA-Q.
You never see this, as the compiler happens to optimise it away, but
it's still a Really Bad Idea (tm). Thanks to someone whose name I have
unfortunately forgotten for pointing this out.

Has been tested in my tree for over two weeks on UP, SMP, and NUMA and
compile tested against a variety of different configs.
