Alan and I were investigating this, but we don't know why the problem
occurs.

This reverts the previous handling of masked_irq, and fixes the problem.

This changes apm.c to invoke suspend.c's save and restore processor
state procedures around suspends, which fixes the SYSENTER MSR problem.

The patch also decouples sysenter.c from SOFTWARE_SUSPEND: the variables
used (only!) in suspend_asm.S are moved there, and the include file now
declares the procedures called from apm.c (previously they were only
called from suspend_asm.S).

Kudos to Wayne Scott @ BitMover for this.

this patch has been sleeping
in Alan tree for quite some time. It updates the depca driver to the
EISA/sysfs API, gets rid of check_region, and properly reserve memory
region. Patch is against latest BK.

it turns out the tulip driver is a much better driver for the integrated
ali1563 ethernet than the dmfe driver... the dmfe driver gets tx timeouts
every ~15s and can't receive over 5MB/s.  but with the small tulip patch
below i'm seeing 11MB/s+ in both directions without problems.

This patch updates the bmac and mace ethernet drivers so that their
interrupt routines return an irqreturn_t, and updates the bmac driver
to use a spinlock rather than global cli/sti.

        This patch update the Wavelan Pcmcia driver for Wireless
Extensions 16, and also remove all the backward compatibility cruft
that is broken anyway.

        This update the Wavelan ISA driver for Wireless Extension 16
(going with my previous patch).

        This patch for 2.5.68-bk11 will update Wireless Extension to
version 16 :
        o increase bitrate and frequency number for 802.11g/802.11a
        o enhanced iwspy support
        o minor tweaks and cleanups

        This patch is only for the core of WE. The patches for the
individual drivers have been sent to their respective maintainers.
	Compared to the previous version I sent you a few weeks ago,
I've just updated to the latest kernel.

        This patch for 2.5.68-bk11 will fix the irq handler of some
obsolete wireless drivers (wavelan, wavelan_cs and netwave_cs) plus
assorted fixes. All those drivers have been tested on a SMP box.

This cleans up the driver big time and gets rid of a big ugly wart
in setup.c.  Note that I don't have the hardware so this is only
compile-tested.

This patch adds dynamic allocation of request structures. Right now we
are reserving 256 requests per initialized queue, which adds up to quite
a lot of memory for even a modest number of queues. For the quoted 4000
disk systems, it's a disaster.

Instead, we mempool 4 requests per queue and put an upper limit on the
number of requests that we will put in-flight as well. I've kept the 128
read/write max in-flight limit for now. It is trivial to experiement
with larger queue sizes now, but I want to change one thing at the time
(the truncate scenario doesn't look all that good with a huge number of
requests, for instance).

Patch has been in -mm for a while, I'm running it here against stock 2.5
as well. Additionally, it actually kills quite a bit of code as well

Limit deadline hash to 32 entries instead of 1024. This has been benched
and profiled extensively and shows no increased system time.

Also, move "hot" entries to the front of the list.

Resend of the ide-cd buggy debug check removal.

increment bi_sector in bio_endio() so make_request_fn drivers don't
have to do this accounting themselves.

send_sig_info() has been broken since 2.5.60.

The function can be invoked from a the time interrupt (timer_interrpt ->
do_timer -> update_process_times -> -> update_one_process -> (
do_process_times, do_it_prof, do_it_virt ) -> -> send_sig ->
send_sig_info) but it uses spin_unlock_irq instead of the correct
spin_unlock_irqrestore. 

This enables interrupts, and later scheduler_tick() locks runqueue
(without disabling interrupts).  And if we are unlucky, a new interrupt
comes at this point.  And if this interrupt tries to do wake_up() (like
RTC interrupt does), we will deadlock on runqueue lock :-(

The bug was introduced by signal-fixes-2.5.59-A4, which split the
original send_sig_info into two functions, and in one branch it started
using these unsafe spinlock variants (while the "group" variant uses
irqsave/restore correctly). 

Thanks to Jonathan Corbet for pointing this out.

Thanks to Mike Anderson for the idea for this.
