[PATCH] forward port of NUMA-Q pci patch from 2.4.19-pre2
This patch enables PCI buses on nodes above node 0 for
the NUMA-Q architecture. It also enables node-directed
port/IO, and cleans up a couple of tiny things that only
affect CONFIG_MULTIQUAD.
This is one of the very early steps on cleaning up the SCSI cdrom
driver. It gets rid of directly accessing the scsi_CDs array in favour
of using the handle we get from the generic cdrom layer. Also uses
local vars instead of many grouped scsi_CDs accesses in other places.
The gain is to get rid of the global, static array of CDROMS
in the end.

ehci-0306, iso, philips, speedups

- tweaks the driver to support the Philips EHCI
- does less in the IRQ handler
- avoids accessing one immutable PCI register
The ISO support should be enough to start writing
drivers, not that I know of any ISO devices that are
really available yet, but it's not fully cooked yet.
As a functional milestone, this means Linux now
handles all kinds of highspeed device I/O. (But it

full or low speed devices through USB 2.0 hubs.)

The compiler warns about about crd_load being defined but never used with

Several people (including Alan Cox) on lkml claimed that the BIOS

As vesafb only compiles on i386, using a more portable API isn't useful,

[PATCH] IDE 17 (not just cleanup)
This is actually an attempt to remove some stall code from
this driver. However if some *real* users complain (Not just
the usuall: "Hey - if someone!" but the "Hey I'm using this!")
I'm all open to reenable it. Since I prepared this patch
yerstoday it doesn't contain the ide_module.h fixup. This will
follow later.
- Don't use the convoluted byte type in ide-pci.c. Just use the proper
u8instead.
- Move ide_get_or_set_dma_base to the only place where it's used and
reorganize the code there by killing the unnecessary
CONFIG_BLK_DEV_IDEDMA_FORCED configuration option.
- Remove unfunctional CONFIG_PKT_TASK_IOCTL code.
- Kill unused ALTSTAT_SCREW_UP code.
- Tons of dead code removed from ide-taskfile.c (#if 0 #endif and
friends)
- Remove unused IDE_DEBUG macro as well as lots of other name space
pollution from ide.h.
- Start using the ide_lock spin-lock for protecting access to data
structures instead of the excessive interrupt disabling games.
- Shorten the proc ouput of the piix initialization module.
- Remove special /proc tape "name" output from ide-tape.c. This was
redundant data which should only show up on syslog anyway.
- Kill the REALLY_FAST_IO undef from the ide.h. This was a mistake
present since far too many years in this driver. The proper way to
deal with broken systems is to define REALLY_SLOW_IO in system
dependent headers or particular driver files. We can always
reintroduce it easy if real users will complain, since OUT_BYTE() and
similar can be used as hooks. But I don't expect anybody reporting
about this. Even on the most broken IDE chip in the world (cmd640
at VLB) undefining this *always* worked for me. Nearly all the code
pieces in the ide driver code *reverted* it's effects explicitly
anyway.
- Remove the obsolete CONFIG_BLK_DEV_4DRIVES support. This was supposed
to support 4 drivers attached at one channel on some older chipsets,
in esp. Tekram 690CD, in the last century. They where all supposed to
work at a register set starting at the base address 0x1f0. Before
complaining that this is removing functionality, please note that this
must have been broken for already quite a long time, since the ide
driver didn't contain the special device selection methods implicated
by this any longer. It didn't scan this port too if PCI host chip
support was enabled (as it is in all those distributions around
there). On the other hand this is the most prominent case of
incoherent use of the mate member in the struct hwif_s. And please
think about how big the probability is, that there are systems out
there, where there are actually 4 drivers on such a channel?
- Streamline module initialization code by removing one shoot functions.
- Make the WAIT_READY value used in case of CONFIG_APM or
CONFIG_APM_MODULE the default, since this is what really reflects the
behavior of modern drives. It won't hurt any other case and finally
removing it is reducing the necessary coverage for overall driver code
testing/analysis.
- Move the IDE_LARGE_SEEK macro to the only place where it's actually
used. Replace the IDE_MIN() and IDE_MAX() drivers with the obvious.
Remove unused SPLIT_WORD and MAKE WORD from the local header.
- Remove CMD640_DUMP_REGS from global scope, since there is no
development done on this any longer. Finally, the way the host chip
initialization routines are called changed in the time between allows
this to remain fully local to the host chip driver in question.
- Some spell checking of comments in the code. (Yeep I have extended my
Vim to do this the "Word" way with nice undercurl lines... mozilla
remains to be fixed...)

There is a problem with the through-8259A mode for IRQ 0 on I/O APIC
systems. Depending on correctness of an MP table, IRQ 0 routing is either
not registered at all or registered at a wrong pin. As a result the 8254
timer IRQ only works by an accident (it's edge-triggered and never
disabled/enabled so it happens to survive this incorrect configuration).
A visible effect is you can't change the affinity for IRQ 0.
Following is a patch that fixes both cases referred to above. The code
looks obvious but it was additionally run-time tested just in case. The
issue is serious -- please apply the patch ASAP. As no changes were done
to io_apic.c since the development fork, the patch applies cleanly both to
2.4 and to 2.5.
Credit goes to Joe for discovering the affinity problem and providing a
fix proposal (incorporated in the final one).
- Disable configuration of the task file stuff. It is going to go away
and will be replaced by a truly abstract interface based on
functionality and *not* direct mess-up of hardware.
- Resync with 2.5.6-pre2.
- Add HPT entries to the fall-back list, since otherwise the driver
won'trecognize the drives. We will have to make this the default
behavior for allnot recognized host chip types.
- Fix compilation with no PCI host chip support enabled.
- Apply the overflow fixes for HPT366 by Vojtech Pavlik.
- Kill the one-shoot functions ide_wait_cmd_taks() ide_wait_cmd() by
moving them to the places where they are actually used. Fix a
potential buffer overflow on the way.
- Fix usage of ide.c as module. Thanks to Adam J. Richter for figuring
out what was wrong.
- Various cleanups all along as well as removal of TONS of
unfinished/dead code.
I think it's sometimes better to remove stuff, which isn't there,
instead of hoping for a "magical day" where it will be finished.

* get_sb_bdev() claims device for fs_type; it means that we don't need
to look through entire least of superblocks anymore - just through
the list of superblocks belonging to that type (i.e. the same thing
we do for non-block filesystems; that will allow to merge quite a
bit of code afterwards).
* sys_swapon claims device for itself; free exclusion with mounting,
end of problems with bogus set_blocksize().
* is_mounted() and is_swap_partition() are gone - what we actually
wanted was "try to claim device for ourselves". Which we can do
now - without races inherent to is_mounted()/is_swap_partition().
* RAID lock_rdev() claims device for itself. I.e. we get rid of
is_mounted() in there (BTW, is_swap_partition() was missing) and
we get protection both ways - not only RAID won't take an already
mounted device, but mount won't stomp on a device claimed by RAID.
There are other places that would benefit from the same (e.g. ext3 with
external journal almost definitely wants to claim device for itself).
Notice that it's a cooperative thing - neither open() nor raw device stuff
claim the block device, so they don't care if device is mounted, etc. So
we don't break fsck and friends - exclusion is between those who know that
they want that exclusion.
