[PATCH] platform update for ES7000
This update only applies to Unisys' ES7000 server machines. The patch adds
a OEM id check to verify the current machine running is actually a Unisys
type box before executing the Unisys OEM parser routine. It also increases
the MAX_MP_BUSSES definition from 32 to 256. On the ES7000s, bus ID
numbering can range from 0 to 255. Without the patch, the system panics if
booted with acpi=off.
This patch has been tested and verified on an authentic ES7000 machine.

I had a problem when compiling a 2.6 kernel with gcc 3.5 CVS. The
prototype for prio_tree_remove in mm/prio_tree.c is inside another

Apparently this isnt valid C, so lets fix it up.

[PATCH] Fix DMA boundary overflow bug
We seem to have found an overflow problem in libata-core.c.
We were trying to DMA to the address range 0xffff8000-0xffffbfff.
In the original version of the code, given that address and
count (0xffff8000 and 0x4000), the variable "boundary" would be
set to 0, causing len to be set to 0x8000 (which is greater than
sg_len). Then at the bottom of the loop, sg_len would be set
to 0xffffc000 (0x4000 - 0x8000), which would then cause the
loop never to terminate (until much of memory was scribbled
over or the kernel died).
The code below should be functionally identical, but not be
subject to the same overflow problem (boundary needs to be a
u33).

[PATCH] ide: identify non decoded master/slave by serial and model
From: Alan Cox <alan@redhat.com>
Some interfaces (notably PCMCIA ones) don't decode the master/slave select so
you get two copies of a device appearing and bad things happening if a user
accidentally uses both.
This checks for the model/serial matching but also knows about non ATA drives
ide=noprobe and a Maxtor problem that was found in Andrew's testing of an
earlier patch. Although M00000.. drives should be RMA'd to Maxtor (and with
info on where they were obtained...) we don't want to break anyone who has
them.
If you get invalid geometry (eg a failed drive) the box hangs on boot because
we try and unregister the registered driver and end up in a locking mess.
We change the behaviour to simply leave the device unattached which avoids
the mess.
This was put in for PPC specifically and defined in the 2.4 tree to be
paranoid about breaking stuff. The actual wait for hwif spin up is however
perfectly correct for all drives. In the normal PC case the PC BIOS has done
this but with other embedded boxes and with things like LinuxBIOS it may not
have done. Thus it should always be done.
"It doesn't work now so it clearly isnt being used 8). We hold the lock
because its a proc function and we then replace the proc functions in the
attach method -> deadlock. It is also incredibly hard to fix without a
major rewrite."
The same is true for HDIO_SET_IDE_SCSI ioctl.
Both were broken 18 months ago in 2.5.63 as a side-effect of locking fixes.

[SPARC64]: Fix delay with HZ==1000.
When I moved sparc64 over to HZ==1000 this added some
problems to the udelay() handling. Specifically, with
slower cpus we could now get underflows to zero for
things like udelay(1) due to the order of multiplies
and shifts.
Fix this, and move it out to arch/sparc64/lib/delay.c
so it is easier to tinker with this in the future and
also to optimize away one of the multiplies for the
constant delay case just like other platforms do.
