The interrupt printout in /proc/stat doesnt make sense on many ppc64
boxes because we remap interrupts. Also, with enough active interrupt
sources /proc/stat might get much bigger than a page which results
in memory corruption.

This patch removes the {un}register_ss_entry/pcmcia_{un}register_socket
calls, and replaces them with generic driver-model-compatible functions.

Also, update the CodingStyle of these cs.c functions to what's recommended
in the Linux kernel.

A new device_class "pcmcia_socket_class" is introduced for PCMCIA and
CardBus sockets.  All socket drivers I could find are updated so that
they register a driver, and -if necessary- the "platform"/legacy device.
This will allow for a cleanup of pcmcia_{un}register_socket() /
{un}register_ss_entry() as well as reflect the parent for pcmcia_bus
devices.

Russell King allowed me to break sa1100_generic pcmcia support for the
time being - so drop that part of the patch for the moment.

This is the generic part of the patch and the architecture specific parts
I have been asked to forward directly to you.

There is an unused variable, `int maxlen', in net/sunrpc/clnt.c ::
rpc_setup_pipedir().

Randy Dunlap included this with the 152x stuff which then got lost in
discussion about core changes and queueing reset. 154x doesnt need the
extra discussion. Also adds a fix to use mca-legacy as needed for 1640
right now

Fixes a request region breakage
Fixes a size request error
Handles a new card type

No lilo since about 1997 has stomped the EBDA

Also recognize the NEC98 busses

Also suggest bugzilla.kernel.org now not the mailing list

This is nice and clean (your tree already knows the idents)

The big thing here is actually turning
'Your bios sucks'
into
'Your bios sucks, but we fixed it and life is good, don't panic'

Which with a vendor hat on is important.  Its currently hard to tell
whether some Linux errors are things to worry about or merely spanking
the manufacturer.  I'd urge people writing error messages to think about
that btw - does it tell the user if the problem is fixed ?

- Converts Video1394 to PCI dma.
- Converts ioctl's to standard interface.
- Various minor fixes
- Merges from 2.5.x tree

Patch from Szabolcs Berecz <szabi@mplayerhq.hu>

With the following patch maxindex is taken from an array instead of
recalculating it all the time.

Patch from John Kim <john@larvalstage.com>

This fixes compile breakage due to recent changes to scsi.h

Patch from: Valdis.Kletnieks@vt.edu

This is a patch to clean things up so compiling with -Wundef becomes feasible
(This patch cuts the number of warnings with 'make allyesconfig' drop from
around 10,000 to several hundred).  It was originally inspired by the
discussion of things that include linux/version.h but don't use the contents
- after doing this, I was able to find that there *WAS* at least one place
where version.h was missing (see following patch).

When EXT3_DEBUG is turned on (by editing the header file) there is one
compile failure and a few warnings.  Fix that up.

driect-io will currently return EINVAL when the application tries to read the
final bit of the file at EOF.  (assuming the file's length is not a multiple
of the filesystem blocksize).

The 2.4 kernelwill reurn 0 (it won't read it at all).

This patch changes the 2.5 kernel to allow that block to be read.

If at the end of direct_io_worker, dio->result is non-zero then we
unconditionally copy that into the return value, potentially ignoring any I/O
errors which were accumulated into local variable `ret'.

Only do the assignment if `ret' is zero.

Patch from steve cameron <steve.cameron@hp.com>

Fix overrun if you have more than 16 attached tape drives + tape changers.
Thanks to Mike Anderson for pointing this out.

Patch from: steve cameron <steve.cameron@hp.com>

Steve sent out a nice series of 11 broken-out patches.  I have lumped them
all together.

- Makes the cciss driver compile in 2.5.60  (from tony@cantech.net.au)

- From randy.dunlap@verizon.net, fix memory leaks in cciss driver

- Allow cciss driver attached disks other than the first to be accessed.

- Zero out cylinders when zeroing out other disk info in cciss driver.

- Remove unused variable from cciss_scsi.c

- This patch makes scsi commands to tape drives have no timeouts.
  Previously the timeout was 1000 seconds, too short, and nothing good
  happens when the timeout expires.  Better to have no timeout.  e.g.  mt -f
  /dev/st0 erase may take about 2 hours 30 min on AIT 100.

- Remove unneeded cciss_scsi init code from cciss driver.

- Remove udelay in command polling routine
- extend timeout to 20 seconds (need for certain multiport storage box)
- Remove unneeded init time code in cciss_scsi.c (thus allowing removal
  of udelay in command polling code.)

- Factor out duplicated read capacity code into common routine in cciss
  driver.

- factor duplicated geometry inquiry code into common routine in cciss
  driver.

blk_congestion_wait() will currently not wait if there are no write requests
in flight.  Which is a potential problem if all the dirty data is against NFS
filesystems.

For write(2) traffic against NFS, things work nicely, because writers
throttle in nfs_wait_on_requests().  But for MAP_SHARED dirtyings we need to
avoid spinning in balance_dirty_pages().  So allow callers to fall through to
the explicit sleep in that case.

This will also fix a weird lockup which the reiser4 developers report.  In
that case they have managed to have _all_ inodes against a superblock in
locked state, yet there are no write requests in flight.  Taking a nap in
blk_congestion_wait() in this case will yield the CPU to the threads which
are trying to write out pages.

Also tune up the sleep durations in various callers - 250 milliseconds seems
rather long.

Patch from Andreas Gruenbacher <agruen@suse.de>

This patch adds trusted extended attributes.  Trusted extended attributes are
visible and accessible only to processes that have the CAP_SYS_ADMIN
capability.  Attributes in this class are used to implement mechanisms in
user space (i.e., outside the kernel) which keep information in extended
attributes to which ordinary processes have no access.  HSM is an example.

Patch from Andreas Gruenbacher <agruen@suse.de>

This adds the XATTR_KERNEL_CONTEXT extended attributes flag.  Kernel code may
use this flag to override extended attribute permission restrictions that
would otherwise be imposed on the calling process.

Patch from Andreas Gruenbacher <agruen@suse.de>

This adds flags parameters to the getxattr, listxattr, and removexattr inode
operations.  This is in preparation for the next patch, which allows
in-kernel code (i.e., modules) to override extended attribute permission
restrictions (which in turn is used by HSM implementations and the like).

Patch from Andreas Gruenbacher <agruen@suse.de>

This patch fixes a bug in the ext2 and ext3 listxattr operation: Even if
an attribute is hidden from the user, the terminating NULL character was
included in the listxattr result. After the patch this doesn't happen
anymore.
