Add hooks to save and restore the graphics state. These hooks are called in
fbcon_blank() when entering/leaving KD_GRAPHICS mode. This is needed by
savagefb at least so it can cooperate with savage_dri and by cyblafb.
State save/restoration can be full or partial.

There is a bug in the complement_mask when you have a 512-character map.
Linux boots to a default 256-character map and most probably your login
profile is loading a 512-character map which results in a bad gpm cursor.

on those machines.
This just moves the gart further out, a more correct fix is in the works

There is a double free in the scsi scan code if a LLDD's slave_alloc()
call fails. There is a direct call to scsi_free_queue and then the
following put_device calls the release function, which also frees the
queue.
Remove the redundant scsi_free_queue.

The CSR contains garbage after a coldboot on RS/6000.
One some systems (like my 44p 270) the MAC address is all FF,
on others (like my B50) it is ff:ff:ff:fd:ff:6b.
It can eventually be fixed by loading pcnet32, set the interface
into the UP state, rmmod pcnet32 and load it again. But this worked
only on the 270.
Only netbooting after a cold start provides the correct MAC address
via prom and CSR. This makes it very unreliable.
I dont know why the MAC is stored in two different places. Remove
the special case for powerpc, which was added in early 2.4 development.

This reverts commit 1b0997f561, which in
turn reverted 34ea80ec6a (which is thus
re-instated).
Quoth James Bottomley:
"All it's doing is deferring the device_put() from the
scsi_put_command() to after the scsi_run_queue(), which doesn't fix
the sleep while atomic problem of the device release method. In both
cases we still get the semaphore in atomic context problem which is
caused by scsi_reap_target() doing a device_del(), which I assumed
(wrongly) was valid from atomic context."

The raid5 stripe cache was recently changed from fixed size (NR_STRIPES) to

This has been broken for months. On resume, we call acpi_pci_link_set()
with interrupts off, so we get a warning when we try to do a kmalloc of non
atomic memory. The actual allocation is just 2 long's (plus extra byte for
some reason I can't fathom), so a simple conversion to GFP_ATOMIC is
probably the safest way to fix this.
The error looks like this..

The IPMI specifcation says the generator ID is 0x20, but that is for bits

This undoes the put_disk patch I sent in before.
If I had been paying attention I would have seen that we call put_disk
from free_hba during driver unload. That's the only time we want to
call it. If it's called from deregister disk we may remove the
controller (cNd0) unintentionally.

This adds a timestamp field to the events sent via the process event
connector. The timestamp allows listeners to accurately account the
duration(s) between a process' events and offers strong means with which
to determine the order of events with respect to a given task while also
avoiding the addition of per-task data.
This alters the size and layout of the event structure and hence would
break compatibility if process events connector as it stands in 2.6.15-rc2
were released as a mainline kernel.
