Turns out that when PM is in use, some D3cold resume paths
could have one thread, holding the network lock, deadlock
in flush_scheduled_work() since an event task is waiting
for that same lock.  Fix is to call that later, when the
lock isn't held.

submitting an URB in a completion handler requires GFP_ATOMIC to be
used.

  - usb_submit_urb must use GFP_ATOMIC in interrupt

So these need to go.

  - remove __devinit from anything called from probe()

This eliminates an error case (current cost, memleak) when
disabling endpoints that have control requests queued.

Changes a handful of things in enumeration error paths.

Bugfixes:
  - consistent cleanup, and consistent return of -Ewhatever/0;
  - a usb_put_dev() gets rid of the extra refcount; this
    one's in bugzilla at osdl.

Diagnostics:
  - new diagnostic for when there's a choice of configurations;
  - merges some diagnostics, for slight rodata reduction.

DMA to a part of a structure is forbidden on the noncoherent architectures.

GFP_DMA has no place in USB drivers, as its meaning is inconsistent
across architectures.

This patch seems to have fallen through the cracks.  It takes a string
constant defined as a macro in initializers.h and instead makes it a
static string in initializers.c.  It also subtracts 1 from the sizeof()
value to avoid transmitting the terminating NUL.

Finally, the patch removes an unnecessary debugging printout -- the value
printed is an _output_ buffer, so of course it won't change.

The ohci d3cold resume path kept re-creating the sysfs files,
and that seemed eventually to cause an oops.  This patch
only creates them on first initialization, not re-init;
and includes some minor debug message tweaks.

This is because that field is going away shortly...

When a dead detached thread has been temporarily zombified because it's
ptraced and its tracer tries to reap it, it deadlocks on SMP.

Here's the fix.

A recent patch changed the rpc/*/channel files to behave
differently depending on whether they were open for read or not.

This hadn't been tested thoroughly.  The cache_reader structure
that was now only allocated when opening for read, had a field that
was iused when writing.

This patch removes that field and takes a different approach to solving
the issue it addressed.

And it has been tested a bit better.

A dying initial thread (thread group leader) sends SIGCHLD when it exits,
but it ought to wait until all other threads exit as well.  The cases of
secondary threads exitting first were handled properly, but not this one.

This exit.c patch fixes that test case, and I think catches the other
potential bugs of this kind as well.  The signal.c change adds some bug
catchers, the second of which will trip on the test case in the absence
of the exit.c fix.

This patch removes the pnp name database code.  Most buses, including
pnp, will be using userspace to name devices in the near future.  Also
dev->name will be removed from the driver model soon.

This patch moves the low level bios calls to a separate file, 
"bioscalls.c".  It is a cleanup that will improve organization of the
pnpbios driver code.

This patch is needed in order to avoid a potential oops.  It is
similiar to the changes made to pci.

This patch moves the resource parsing functions from support.c to the
pnpbios driver.  Originally these functions were intended for other
pnp protocols but in reality they are only used by the PnPBIOS driver.
This patch greatly cleans up the code in both the parsing functions
and their connection with the pnpbios driver.  Also note that
pnpbios.h has been added for local pnpbios functions.

This is not needed.

  This patch is similar to the disabled resource patch in that it
  avoids direct numeric comparisons with data in unset resource
  structures.

ARXESCSI does not have the interrupt routed to the host
machine, so we need to babysit the host interface.  We
do this via a variant of the normal command function in
fas216.c

Fix a bug in the procfs file handling in the EESOX SCSI

  This patch fixes two places where the handling of page boundaries was
incorrect and caused to IO_ERR's when it shouldn't have.

1.  In decode_write it was just a small typo.
2.  In decode_compound we avoid using READ_BUF, but don't provide all of
it's functionality, specifically crosses a page boundary.

Though the nfsd module can create this, having it always
there makes auto-loading-on-mount work better.

Note: it was previously recommended that the nfsd filesystem be mounted
on /proc/fs/nfs, which I was never comfortable with.
Henceforth the recommended location will be /proc/fs/nfsd.
nfs-utils 1.0.6 and later will support both.

Such a request would cause the nul terminator to be written
to some other page, and cause havoc.

Also rearrange two tests to avoid the possibility of testing the byte
just past the end of a buffer - doing so can causes an oops with appropriate
kernel-debug config options

The 'acl' folks would like an export flag, so this patch
reserves one and also discards some that aren't used and never
will be (for the named purpose).

NFSEXP_CROSSMNT used to mean something different, so
using a different name reduces the chance of confusion.
Also there is currently a surplus of vowels, so there is
no need to be frugal

When a sunrpc/cache channel is not open for reading, the
cache doesn't bother making and waiting for up-calls.

However it doesn't currently distingish between open-for-read/write
and open-for-write, so an op-for-write will look like a reader
and will cause inappropriate waiting.

This patch checks if a file is open-for-read and will only register
a file as a reader if it really is one.
