Thanks to Matt Wilcox for the info.

This gets rid of the port semaphore, and the serialization caused by
that, and replaces it with the proper reference counting logic for
the usb serial object.

This solves lots of races when drivers hold a reference to the usb_device
after the device is physically removed from the system (like when a user
has a open handle.)  This now prevents any new urbs being submitted or
canceled for the device.

doesn't define ndelay(), fall back on udelay().

This is version 23 or so of the POSIX timer code.

Internal changelog:

 - Changed the signals code to match the new order of things.  Also the
   new xtime_lock code needed to be picked up.  It made some things a lot
   simpler.

 - Fixed a spin lock hand off problem in locking timers (thanks
   to Randy).

 - Fixed nanosleep to test for out of bound nanoseconds
   (thanks to Julie).

 - Fixed a couple of id deallocation bugs that left old ids
   laying around (hey I get this one).

 - This version has a new timer id manager.  Andrew Morton
   suggested elimination of recursion (done) and I added code
   to allow it to release unused nodes.  The prior version only
   released the leaf nodes.  (The id manager uses radix tree
   type nodes.)  Also added is a reuse count so ids will not
   repeat for at least 256 alloc/ free cycles.

 - The changes for the new sys_call restart now allow one
   restart function to handle both nanosleep and clock_nanosleep.
   Saves a bit of code, nice.

 - All the requested changes and Lindent too :).

 - I also broke clock_nanosleep() apart much the same way
   nanosleep() was with the 2.5.50-bk5 changes.

TIMER STORMS

The POSIX clocks and timers code prevents "timer storms" by
not putting repeating timers back in the timer list until
the signal is delivered for the prior expiry.  Timer events
missed by this delay are accounted for in the timer overrun
count.  The net result is MUCH lower system overhead while
presenting the same info to the user as would be the case if
an interrupt and timer processing were required for each
increment in the overrun count.

Fixes hangs on Micron Samurai boards

also Enable ATI IGP/ALi combo

This is the only user I'll feed you this time. As with 2.4 I want it to
run for a bit on read only media first 8)

We need to copy the new io op. Actually we need to shoot the entire mess
in this function and make the drivers always set it but not today.

(is_flashcard is unneeded outside ide_probe as we have a drive->flash check)

Some drivers need this. Its in the core as the core eventually needs to
be doing the tracking here

The iops struct may be a good idea in the longer run but right now its
unused and its mess that can be restored neatly later on.

(second hunk just makes 2.4/2.5 header match format)

Now handled at runtime

We cannot do an identify on a drive with no driver loaded. The kernel
has a ton of half backed "if no driver" cases but they dont cover all
cases and its a mess.

For now we rely on the probe time identify unless a driver is loaded. A
proper fix (an 'ide-unassigned' driver) will follow later

Fix crash with slave and no master
Fix crash with hdb=noprobe hdb=cdrom
Fix crash with pre ATA devices refusing IDENTIFY
Fix flash slave making master disappear
Add interfaces that the PPC uses to do disk spin up when the BIOS has not
Add framework to allow hdparm -d1 on a box built with IDE_DMA_ONLYDISK
Fix identify framework so we can fix the proc identify crash too

Also adds the new OUTBSYNC iop
