broken on SMP (due to expecting global irq locking).

From Andries Brouwer <aebr@win.tue.nl>: we discard the double
release keypress, but we did it without clearing the "last byte
was E0" flag. So the next byte in the input stream would get
corrupted.

- let more drivers that don't compile depend on BROKEN
- MTD_BLKMTD is fixed, remove the dependency on BROKEN
- let all drivers that don't compile on SMP (due to cli/sti usage)
  depend on a BROKEN_ON_SMP that is only defined if !SMP || BROKEN
- #include interrupt.h for dummy cli/sti/... in two files to fix the
  UP compilation of these files

I marked only drivers that are broken for a long time and where I don't 
know about existing fixes with BROKEN or BROKEN_ON_SMP.

ide: forward-port siimage driver changes from 2.4.22

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>

This patch seem to have been lost, so here it is again.  It fixes an Ooops
on unregistering hwifs due to the device model now having mandatory
release() functions.  It also close the possible race we had on release if
the entry was in use (by or /sys typically) by using a semaphore waiting
for the release() to be called after doing an unregister.

Include vmalloc.h to fix compilation of raw1394.c

  o scsi/imm.h: use c99 style initialization

  As far as I verified this also fixes a bug when doing the
  table lookup for IMM_EPP_32, that would result in "Unknown"
  as IMM_EPP_32 is equal to 6 and there is the #ifdef...

ChangeSet@1.1386, 2003-09-02 00:11:07-03:00, acme@allegro.kerneljanitors.org
  o scsi/*.h: remove not needed #define NULL

ChangeSet@1.1385, 2003-09-02 00:05:16-03:00, acme@allegro.kerneljanitors.org
  o scsi/3w-xxx.h: use c99 style init

Previously, default aliases were hardwired into modutils.  Now they
should be inside the modules, using MODULE_ALIAS() (they will be overridden
by any user alias).

We had some races where we testecd (or set) TS_USEDFPU together
with sequences that depended on the setting (like clearing or
setting the TS flag in %cr0) and we could be preempted in between,
which screws up the FPU state, since preemption will itself change
USEDFPU and the TS flag.

This makes it a lot more explicit: the "internal" low-level FPU
functions ("__xxxx_fpu()") all require preemption to be disabled,
and the exported "real" functions will make sure that is the case.

One case - in __switch_to() - was switched to the non-preempt-safe
internal version, since the scheduler itself has already disabled
preemption.

Just to be on the safe side.  Suggested by Ingo Oeser.

Helpers moved:
netif_poll_{enable,disable}, __netif_rx_complete, netif_tx_disable

Use the helpers in net/core/dev.c.

This patch creates a sections.h for the m68knommu architecture.
Nothing special needed, just an include of the generic code.

This patch creates a local.h for the m68knommu arhcitecture. Like
most others architectures it is just an include of the generic one.

The linux/drivers/scsi/sr.c code will issue a MODE_SENSE[_10] command to
a device as the first command sent to the device.  If the device has
just come out of reset, it will likely respond with a UNIT_ATTENTION /
NOT_READY status, which causes the MODE_SENSE to fail.  In fact, the
device may have several UNIT_ATTENTION conditions queued up (power-up
reset, media change, etc.)

This results in the mode page 0x2a data not being properly read and
interpreted.  As an end-effect, things like packet-writing don't work
(because the writeable bit is not set).

The solution to this is to issue one or more TEST_UNIT_READY commands to
the device to clear any pending UNIT_ATTENTION conditions.  This is the
technique used by sd.c -- in fact, this code was lifted directly from
sd.c

At some point in the future, abstraction of this initial TEST_UNIT_READY
code between all high-level SCSI drivers may be apropriate.  For now,
this patch makes sr.c issue TEST_UNIT_READY to clear the UNIT_ATTENTION,
thus allowing the mode page 0x2a code to work properly.  Given the
approaching 2.6.0-final release, I urge that this patch be accepted.

Also, call pci_disable_device() in PCI ->remove handler,
to match pci_enable_device() in PCI ->probe handler.

(preferred over alloc_etherdev + 8390-specific ethdev_init)

the SG_IO and SCSI_IOCTL_SEND_COMMAND ioctl's. That just
screws things up when the drive is mounted.

If somebody wants exclusive access, he should indicate that
at open time.

I've been trying to remove these, but apparently new ones crop up. Lets
just call it io scheduler, none of the ones in the kernel are using the
classic elevator algorithm.
