When taskfile delivery is improved, we will actually perform
this command, instead of no-oping it.

For now, this is cosmetic except for removing an annoying message
that some users see.

The ->tf_load and ->exec_command driver hooks were changed to assume
that PIO was the only type of taskfile ever delivered to these functions.
This will be true... in the future, but not today.  In other drivers
this change was not needed, but Promise executes commands differently
due to its "ATA packet" hardware features, so the Promise drivers need
this change reverted.

The attached patch updates generic HDLC:
- fixed some carrier-related problems (Cisco HDLC and FR links could
  report valid link when no carrier was detected at startup).
- fixed kbuild problems with wanxl firmware (building kernel in separate
  tree). $(src)/wanxlfw.inc is now wanxlfw.inc_shipped.

This patch is what we want.  We don't in fact need to do the read
lock, only the write lock, which is what the original patch did.
However, we need to do it in ppp_synctty.c as well as ppp_async.c.

Revert CONFIG_NET_GIGE change.

The proper fix is _not_ NET_ETHERNET or default twiddling,
but better overall organization of the ethernet driver selection,
which would include not only CONFIG_NET_GIGE but other options as well.

Reverted back to old behavior until a full and complete solution
appears (and people like it, of course).

* islpci_eth.[c,h], islpci_dev.[c,h], isl_ioctl.[c,h] : added
  support for avs header in monitor mode. Based on the work of
  Antonio Eugenio Burriel <aeb@ryanstudios.com>. Unified packets
  header (rfmon_header and rx_annex) for iwspy.

        * islpci_eth.c, islpci_dev.h, isl_ioctl.c : iwspy support.

* islpci_eth.[c,h] islpci_dev.[c,h] : reset card on tx_timeout.
  Patch submited by Denis Vlasenko <vda@port.imtp.ilyichevsk.odessa.ua>

* oid_mgt.[c,h] : added type to oids. New functions :
  oid_cpu_to_le(), mgt_le_to_cpu() and mgt_response_to_str().

* isl_ioctl.c : use private sub-ioctls. Added a
  bunch of private sub-ioctls. Removed the le??_to_cpu and
  cpu_to_le??. Give the error code when sending wireless
  events.

* Remove CVS tags from source

I received a bug report that a PLIP interface was incorrectly identified
as wireless because plip_ioctl did not check what the value of cmd is
before processing the request.

This patch fixes exactly that.

Fix a race identified by Jeremy Kerr <jeremy@redfishsoftware.com.au>: if
update_process_times() decides to deliver a signal due to process timer
expiry, it can race with __exit_sighand()'s freeing of task->sighand.

Fix that by clearing the per-process timer state in exit_notify(), while under
local_irq_disable() and under tasklist_lock.  tasklist_lock provides exclusion
wrt release_task()'s freeing of task->sighand and local_irq_disable() provides
exclusion wrt update_process_times()'s inspection of the per-process timer
state.

We also need to deal with the send_sig() calls in do_process_times() by
setting rlim_cur to RLIM_INFINITY.

Patch from Nicolas Pitre

[patch rediffed]

On PXA27x the memory and LCd clocks are different.
Also clean the PXA27x clock code a bit.

Remove 26-bit ARM region reserves.

All region reserves start at PHYS_OFFSET, and we only ever have one,
so set res_size and reserve the region from PHYS_OFFSET size res_size.
    
Don't free the .init sections on Integrator/CP - they sit in the SSRAM
obscured region so we are unable to use them for DMA purposes.

Ingo explains:

The condition is 'impossible', but the whole balancing code is
(intentionally) a bit racy:

                cpus_and(tmp, group->cpumask, cpu_online_map);
                if (!cpus_weight(tmp))
                        goto next_group;

                for_each_cpu_mask(i, tmp) {
                        if (!idle_cpu(i))
                                goto next_group;
                        push_cpu = i;
                }

                rq = cpu_rq(push_cpu);
                double_lock_balance(busiest, rq);
                move_tasks(rq, push_cpu, busiest, 1, sd, IDLE);

in the for_each_cpu_mask() loop we specifically check for each CPU in
the target group to be idle - so push_cpu's runqueue == busiest [==
current runqueue] cannot be true because the current CPU is not idle, we
are running in the migration thread ... But this is not a real problem,
load-balancing we do in a racy way to reduce overhead [and it's all
statistics anyway so absolute accuracy is impossible], and active
balancing itself is somewhat racy due to the migration-thread wakeup
(and the active_balance flag) going outside the runqueue locks [for
similar reasons].

so it all looks quite plausible - the normal SMP boxes dont trigger it,
but Bjorn's 128-CPU setup with a non-trivial domain hiearachy triggers
it.

active_load_balance() looks susceptible to deadlock when busiest==rq.
Without the following patch, my 128-way box deadlocks consistently
during boot-time driver init.

From: Matt Domsch.
The E7205 doesn't have an AGP header, so printing this message is
pretty much useless.  Also make it KERN_WARNING as well, as it's
not really worthy of a KERN_ERR
 

(the bios might not have done that).

From: Arjan van de Ven

This option only worked for the amd64 driver.
On every other driver, the only thing it did was
make it not printk the banner on startup.

This is horribly broken due to a jiffy wrap bug, we never get out of
the while loop, preventing booting on a kernel with this driver
compiled in. (See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=124495)

The warning message there has never been reported in any bug report
that google can find, so I'm of the opinion that this driver is trying
to be too clever for its own good.  Rip out the jiffies logic completely,
it should be totally unnecessary.

Arjan noted that in some cases, the build fails.
This should fix it up.

/sys/power/state the radeonfb driver tells me its suspending to state 1 but
the display does not get turned off.  It turns out to be a small typo in
