brking@us.ibm.com ee0a90fa3e [SCSI] ipr: Support new device queueing model
New ipr adapters support a new device queueing model in the
adapter firmware. The queueing model is the NACA queueing model,
but it does not mean use of NACA is required. The new model removes
some of the adapter firmware queue state that made handling QERR=0
almost impossible. The queueing model on older adapters included the
concept of a queue frozen state, which would freeze the response
queue in the adapter when a check condition occurred, requiring a
a primitive to resume the queue. The new queueing model removes this
complexity.

brking@us.ibm.com 11cd8f1201 [SCSI] ipr: Disk array rescanning fix
IPR RAID arrays show up on a virtual scsi bus, with a scsi bus number
of 255, which is generated by the adapter microcode. For the initial
scan of the host, we manually scan this bus since it does not obey
SAM in regards to sparse LUNs and the disk array devices do not have
a consistent product id to use scsi core's blacklist. If /proc/scsi/scsi
or sysfs is used to delete one of these devices, the device will not
be able to get added back by rescanning the host since scsi core
will see ipr's max_channel as 4, rather than 255. Update max_channel
after the initial scan so that ipr raid arrays can get re-added
if they get deleted.

my patch "x86: initialise tss->io_bitmap_owner to something" (commit ID
d5cd4aadd3) introduced a problem with a

The problem is that a process switch return causes tss->io_bitmap_base
to be set to IO_BITMAP_OFFSET so that the fault (that *really* sets the
io bitmap) never triggers.

Samuel Thibault 88dcb6c411 [PATCH] Set the vga cursor even when hidden
Some visually impaired people use hardware devices which directly read
the vga screen. When newt for instance asks to hide the cursor for
better visual aspect, the kernel puts the vga cursor out of the screen,
so that the cursor position can't be read by the hardware device. This
is a great loss for such people.

Here is a patch which uses the same technique as CUR_NONE for hiding the
cursor while still moving it.

Mario, you should apply it to the speakup kernel for access floppies
asap. I'll submit a 2.4 patch too.

lock up on probing certain phy addresses or probing doesn't return
0xffff when nothing is found at the address. A new driver I'm
