This patch seems to have been forgotten about, so here it is again,
this time against 2.6.4-rc1.  This really needs to be send upstream,
though I don't know where we got to with this one.  Maybe we should
put it in akpm's tree for a while?

It's essentially more of the "don't deadlock if you pull out a
PCMCIA network card and it's currently configured up" patch which
went in recently for PCMCIA NIC cards.

Note that hp100 in 2.6.4-rc1 is still broken wrt EISA probing, since
it lacks the terminating entry in the EISA ID list. This one-liner
should take care of random crashes that are often reported to LKML :

To hotplug-remove virtual devices, we need vio_find_node() so we have a
pointer to pass to vio_unregister_device().

vio_dev->unit_address only holds 32 bits of information anyways, so no
need for 64-bit field.

This fixes the ulblp transfer length code, which would otherwise skip
the final iteration and lead to incomplete printer output (and us
waiting forever for the transfer to complete)

Here's a much better version.  The real bug was of course that the
get_user/put_user for data_direction were transposed.

This patch also fixes the translation of "quiet" and "timeout" to be
safer and clearer (instead of memcpying them as two ints and knowing
that "quiet" is first and assuming that "compat_int_t" is always the
same as the native "int", the code now handles them explicitly).

We should use "access_ok()" and __get_user/__put_user to generate better
code for this, but it's not performance-critical, so we don't care.
Some other day, perhaps.

Previous Kconfig change was incorrect, this is a better one.

This part of the patch seems to have been lost (root_hydra_dev is no more):

The SA1111 appears to re-trigger an interrupt immediately following
a successful interrupt, despite no interrupt actually pending.

Maurice van der Stee noted that he got an oops on a HPFS filesystem when
saving an edited file..

  <blinks>
  <wonders whereTF do we assign hpfs1_i and hpfs2_i if both inodes are non-NULL>
  <finds the patch in question>
  <stares at jgarzik>

This fixes it.  That, BTW, means that *nobody* had ever tried to use
hpfs r/w since 2.5.3-pre3.

The pdflush kernel threads can lead to an unbounded chain of thread-creations
which can overflow the kernel stacks because we didn't uses to reset
the stack on kernel thread-creation.  We do now.

Reported by Andreas Schwab, tracked down with help from Keith Owens.

This patch changes the I/O SAPIC code to cache the low 32 bits of the mask
word in kernel memory.  This greatly speeds up mask_irq() and unmask_irq().

Normally, these operations are not on the speed-critical path of the
kernel but with certain devices drivers (including users-level device-
drivers) they can become performance-critical.

        - fix bug in pfm_unload(), not allowed when not on correct CPU for
          system-wide
        - some perf/cleanup in overflow handler
        - fix reset_pmds to be on a per PMD basis on counter overflow rather
          than global
        - remove timing debug code on messages
        - no kernel info leak on PFM_END_MSG
        - remove double-store on reg_flags for pfm_write_pmcs, pfm_write_pmds
        - on restart reset_pmds is 0 by default
        - cleanup useless macros
        - cleanup some debug prints
        - added ability to remove debug code
        - streamlined sys_perfmonctl(), pfm_read_pmds(), pfm_write_*()
        - added current->tgid to default format sample header by using one
          reserved field

The problem was that IDE-disks on machines with IDE harddisks,
memory above 4GB and no hardware I/O TLB would go BUG_ON() in
blk_queue_bounce_limit() because the IDE-controller could only
address 4GB of memory and that was much less than BLK_BOUNCE_ISA
(which is equal to ISA_DMA_THRESHOLD).  Note that the problem does
NOT trigger with CD-ROMs, which always uses the software I/O TLB
(and hence bounce-buffers) on such machines.

The best fix seems to be to simply lower ISA_DMA_THRESHOLD to 4GB-1 since
that will ensure that the IDE block layer allocates memory with GFP_DMA,
which will minimize bounce buffering.

Jeff, here is a cleaned up version of the 2.6.3 hp100 isa (non-modular) probing.
It needs to check for the board being present before reading the signature.

Allow command line partitioning for use with Integrator flash.

Tighten AFS partition checks:
- check footer checksum.
- check that the image name is NUL terminated.
- return error from mtd->read intact.
This prevents us finding bogus AFS partitions.

This makes it possible for people like me with a small-mem G5 to enable
the DART.  I see two reasons for wanting to do so:

1. To debug/test DART/iommu code itself (small audience, including
   myself).
2. To debug drivers on small-mem machines, since bad pci_map*() usage will
   be punished (possibly larger audience).

This patch fixes a bug which could cause do_softirq() to be called
