From Herbert Xu

There's a problem with bio segment accounting for pages that reside
above the bounce limit of a queue. When submitted, they may be
considered part of another segment. A condition that changes when the
page gets bounced. This can cause us to send bio's that have too many
segments to a driver.

The best fix is to always consider pages above q->bounce_pfn as seperate
segments. That's the conservative approach and the easy fix.

Problem identified and fixed by Herbert Xu.

This fixes visws subarch which was broken by asm-i386/hw_irq.h changes

- Missing spin_lock*() calls before tp->link_config twiddling.
- Missing assignment to tp->link_config.autoneg

IRDA was restoring IRQ flags in a different function from which they
were saved which explodes on certain platforms.  It did not need to
use _irq{save,restore}() anyways since the seqfile layer always invokes
these routines from user context with interrupts enabled, so using
plain spin_{lock,unlock}_irq() works just fine.

- Prevent 'self' leak on error in irlmp_open.
  ASSERT is compiled in only with DEBUG option => risk = 0.

Original patch from Chris Wright.

- Prevent sending status event to dead/kfree sockets
- Disable PPP access before deregistration
  PPP deregistration might sleep -> race condition

- Do not do copy_from_user() under spinlock
- Always access self->skb under spinlock

Original patch from Martin Diehl.

This fixes a panic-at-boot when ACPI Hotplug PCI is compiled in, but
ACPI is disabled.  It just makes sure that the list is properly
initialized statically instead of depending on runtime initialization
that may or may not happen.

Bug noticed by Russell King.

ioremap_nocache() doesn't need to check for physical address
wraps because __ioremap() has already done that;
fix calculation of npages to handle non-aligned phys_addr;

get_unique_tuple doesn't check that the tuple is unique if it finds
a hash_by_src match.

Noticed by Stuart_Hayes@Dell.com:

I've noticed that, in the 2.6 (test 9) kernel, the "cmd" field (of type int)
in struct request has been removed, and it looks like all of the code in
ide-tape has just had a find & replace run on it to replace any instance of
rq.cmd or rq->cmd with rq.flags or rq->flags.

The values being put into "cmd" in 2.4 (now "flags", in 2.6) by ide-tape are
8-bit numbers, like 90, 91, etc... and the actual flags that are being used
in "flags" cover the low 23 bits.  So, not only do the flags get wiped out
when, say, ide-tape assigns, say, 90 to "flags", but also the 90 gets wiped
out when one of the flags is modified.

I noticed this, because ide-tape checks this value, and spews error codes
when it isn't correct--continuously--as soon as you load the module, because
ide-tape is calling ide_do_drive_cmd with an action of ide_preempt, which
causes ide_do_drive_cmd to set the REQ_PREEMPT flag, so "flags" isn't the
same when it gets back to idetape_do_request.

Set filp->private_data in idetape_chrdev_open() to point to a opened drive,
otherwise driver oopses during future access to tape character device.

Thanks to Stef van der Made <svdmade@planet.nl> for testing ide-tape fixes.

Moving isapnp further down in the bus initialization obviously sparked
some new problems.

Instead, remove the legacy netdev probing function from dev.c and give
it its own initcall later in the cycle.

This patch prevents a crash that happens when per-CPU data is allocated
only for CPUs that are online.

Trivial build fix for the debug code in drivers PCI.  Seems like nobody
has had to use this code in a long time.

If sg->dma_address is set, we try to do a __pa() on a dma_address,
then, later, create a dma_addresss from a munged dma_address.  When
this bogus dma_address is used by the card, it results in MCAs.

Only regular files, directories and symbolic links can have any
blocks allocated to them - other types of files have different
metadata in their inodes and should not get to the truncation
paths. Enforce this in fs/minix/inode.c.

Without this, deleting a block or character device can cause
minix filesystem corruption. Noted by Konstantin Boldyshev.

Getting a signal while in vm86 caused warnings because we still had
interrupts disabled - for no good reason. Enable interrupts before
accessing user space.

This extends the agppart table with three new SiS chipsets that must be
handled as the other ones.  No actual code changes.
