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

This separates out the PIRQ table parsing to vendor-specific
code, which allows us to handle specific vendor quirks. In
particular, SiS has a really funky notion of what PCI device
ID's are meant to be.

Some hardware designers seem to be hitting the recreational
drugs a bit too heavily. Tssk, tssk.

The Sis96x irq routing update is confirmed to fix at least
one laptop.

From Vojtech Pavlik <vojtech@suse.cz>.

Change AMD8111 and nForce2 max speed to UDMA133.

Add workaround for Serenade mainboards which only handle UDMA100.

Fix printing of chipset name.

Fix some whitspace issues.

Original 2.4.23-pre4 patch by Allen Martin <AMartin@nvidia.com>.

This does not add any new code, it only adds new PCI ID's and related
info to the existing driver.

Some machines with the SIS 96x southbridge have it set up
to claim it is a SIS 503 chip. That breaks irq routing logic
among other things. Fix it properly by making everybody aware
of the duplicity.

JFS isn't happy it thinks a file has been removed, and link() increases
its nlink count back from zero.  In 2.4, i_zombie prevented this race
condition.

__invalidate_metapages references mp->page after after releasing the
meta_lock spinlock, without increasing the use count.  This is racy and
unnecessary since setting the META_discard flag is sufficient.
block_invalidatepage() will be called when the metapage is released.

Bug reported by Paul Mackerras: if a module parameter fails, we didn't
call module_arch_cleanup().

On x86 this was harmless (module_arch_cleanup() is a no-op), but on
other architectures like PPC this causes inconsistent data structures
and subsequent oopses.

This bug prevents Alphas with older firmware from booting if there
is a card with PCI-PCI bridge that supports 32-bit IO.
This has happened on AS2100 with a quad-tulip card, for example:
 - initially, the I/O window of 21152 bridge was 0x10000-0x10fff,
   as set up by firmware;
 - pci_setup_bridge() is going to change this, say, to 0xa000-0xafff:
   first, it updates PCI_IO_BASE_UPPER16 and PCI_IO_LIMIT_UPPER16
   registers, so that IO window temporarily is at 0x0000-0x0fff,
   which effectively blocks up all legacy IO ports in the lower
   4K range, such as serial, floppy, RTC an so on;
   does debugging printk - machine dies here with recursive
   machine checks as the serial console has gone.

Moving (or disabling) the debugging printk is not a solution -
there is possibility that timer interrupt (which might access RTC
ports) occurs between writes to lower and upper parts of the
base/limit registers.

The patch temporarily disables the IO window of the bridge by
setting PCI_IO_BASE_UPPER16 > PCI_IO_LIMIT_UPPER16 before doing
an update. It's safe, as we don't have any active IO behind
the bridge at this point. Also, it's a NOP for bridges with
16-bit-only IO.
Similar (but simpler, as we always clear upper 32 bits) fix
for 64-bit prefetchable MMIO range.

(x >> 32) is undefined on a 32 bit integral variable in C; In contrast
(x >>16 >> 16) is fine (and gets optimized out to 0, while (x >> 32)
gets optimized out to a nop).
