This patch fixes the code that workaround lockups when accessing
the config space of devices on K2 when they are shut down. The
code was there but in the wrong place ;) And a typo prevented the
ohci1394 version of it from working.

When adding an additional device, a variable which has been removed
is accessed.  Adding the first device or a 4-port card works.
Adding a second device was not done in PCI hot plug testing.  Now
tested on IA32.

The bug turned out to be memory corruption by DMA, and
the corrupted address made it that much more obvious.

Getting some blood sugar made the real fix for that become
obvious! This replaces the preceding TEMPORARY hack.

Only unlink EDs that aren't already being unlinked!

Duh.

Fix some OHCI TD list corruption issues:

    - Don't rewrite HC registers holding ED pointers until the HC
      had a good chance to finish using them.

    - Don't ever modify ed->hwTailP

Adds text describing the different ED states.

Adds TEMPORARY hack that may make a "rm_list becomes circular" bug
continuable.

This patch was trying to work around buggy SMM bios but causes problems
by not deasserting NMI irq line (reported by Thomas Schlicht) for some
integrated local apic.

This patch was written originally as an optimization (with the side
effect to fix those bugged bios) but was never applied to 2.4 tree.

The rational was: fix your bios instead. 

Cset exclude: akpm@osdl.org|ChangeSet|20040219045328|16041

Without this patch, IA32 programs will stall when CONFIG_PREEMPT is enabled.

Remember to invalidate the task->tty of threads, otherwise prod_pid_stat()
later stumbles over the dangling pointers and crashes.

The condition still seems to happen on ppc64.

sock_sendmsg() modifies iovec passed to it - it sets all length members of
iovec array to zero on success transmission (and even on failed if it
fails after iovec copy, but...) and advances pointers to point at the end
of buffers used. This has an unfortunate effect that ncpfs's retry on
failure does not work for IPX/UDP connections - kernel refused to do anything
because length from iovec was 0 while length passed to sock_sendmsg() was
correct.

This simple fix gets rid of a problem by creating temporary iovec copy, which can
sock_sendmsg destroy if it has such wish.

This adds infrared remote support for a few more bt878-based TV cards.

From Mike Christie <michaelc@cs.wisc.edu>

The first three bio and request flags are no longer identical.  The bio
barrier and rw flags are getting set in __make_request and get_request
respectively, and failfast is getting left out.

This sets the request's failfast flag in __make_request when the bio's
flag is set.

The ppc64 fix last week (enforcing permissions on the kernel when
accessing userspace pages) uncovered a bug on POWER3/RS64. We werent
zeroing the segment table entry before overwriting it and it was possible
for the ks bit to be set on a kernel segment.

The VSID mask was also changed to match reality (we only use 13 bits).

This patch reworks the early boot calls to OF to initialize displays.

All present displays are now initialized in reverse order so the
OF console stays on the first one. Initializing them all is necessary
for dual head configurations as we need OF driver to properly setup
the secondary TMDS of the video card, XFree isn't able to do that
currently

The assembly code used to callback into Open Firmware client
interface in 32 bits mode used to backup the stack pointer in
the SPRG2 register.

That upsets Apple's implementation of Open Firmware significantly
and maybe others, causing them to crash in _some_ operations,
apparently the trigger is to cause a segment or hash table
fault, typically happens when letting that code initialize the
second display.

This patch fixes it, along with other cleanups of that asm code,
it did unnecessary register restores and backing up the stack
pointer is actually useless anyway.

Strangely, I though I fixed that a long time ago, but it was still
broken in the current tree...

Drivers like radeonfb fail to find the OF device matching a given PCI
device on the G5 AGP bus because of some bus renumbering tricks.  This
patch fixes the problem by fixing the bus numbers in the OF node.  This
corrects radeonfb and other drivers looking for EDID / PLL datas in the
OF node.

Especially with REGPARM these things actually matter.

This fixes possible lockups in pmac_zilog when beeing flooded with
incoming data (not that other serial drivers share the same race, I told
Russel about it already).  It also fixes some SCC initialization
problems, add some PM callback, and fix the irda setup code.

This does cosmetic changes the pmac_zilog, changing the use of "up" as
an identifier in favor "uap" to avoid collision with semaphores, use
proper debug macros, and a few other cosmetic bits.

Original patch from Stephen Hemminger

Move last bits of code out of irsyms and onto irmod.c where
initialization happens.

Move irda_debug parameter out of irsyms.c into irmod.c
and make it a new style module parameter.

irda_device_setup can now be static, only called from alloc_irdadev.

Also, make type __u16 rather than unsigned short to
match input parameter.
