There seemed to be increase in Athlon users reporting MCEs in 2.6 that
they never saw in 2.4 and I didn't buy the "2.6 pushes hardware harder"
for a second given folks are running 2.4+preempt+O(1) etc patchkits
without problems.

So I did a mini-audit of the mcheck code.

How embarressing. Another fix that went into 2.4 that never made
it forward. Once I'm done with various Red Hat administrivia
I'll see if I can devote some time to going through the changesets
mailing list. I wonder just how many other really stupid bugs
like this got fixed and not brought forward.

In order to properly track down who needs to program the IRQ MUX
register, add the subsystem vendor and device IDs to the kernel
message indicating discovery of the cardbus bridge.

The IRQ steering code operates too early at present, and actually
prevents us detecting ISA interrupts.

We should not touch the IRQ MUX register on TI bridges - only the
machine itself knows the right value for this.  The kernel doesn't
have the knowledge to know what function the cardbus controllers
multi-function pins have been assigned by the hardware manufacturer.

Currently, yenta does not try to clean up after an error occurs while
initialising a cardbus socket.  This cset ensures that we release
resources.  We also claim the cardbus MMIO memory resource.

pnp_x_valid returns 1 if valid.  Therefore we should be using
!pnp_port_valid.  Also cleans up some formatting issues.

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
driver.

Use the ioremapped region for accesses to SA1111 IRQ
controller registers.

  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.

Resided in arch/i386/kernel/dmi_scan.c and was not used by any of the 
blacklist functions. If it turns out to required, we can add it back later.
