Fix some bugs in the patch that converted the IOC4 driver from port IO ops to
memio ops.
http://marc.theaimsgroup.com/?l=linux-ide&m=114895892231438&w=2
Problems fixed are:
- Call to default_hwif_mmiops() was not being done until _after_
first IO operation, resulting in the first IO operation being
done as a port IO op, instead of memio.
- request_region() calls needed to be request_mem_region()
- Incomplete error case handling.
- Non-usage of ioremap() and __iomem.

The via-pmu backlight code (introduced in 2.6.18) has various design issues
causing crashes on machines using it like the old Wallstreet powerbook
(Michael, the author, never managed to test on these and I just got my hand
on one of those old beasts).
This fixes them by no longer trying to hijack the backlight device of the
frontmost framebuffer (causing that framebuffer to crash) but having it's
own local bits instead. Might look weird but it's better that way on those
old machines, at least as a last-minute fix for 2.6.18. We might rework
the whole thing later. This patch also changes the way it gets notified of
sleep and wakeup in order to properly shut the backlight down on sleep and
bring it back on wakeup.

Olaf Kirch of SuSE tracked down a problem where module unloads of the IPMI
driver would occasionally result in Oopses. He tracked that down to a
variable that wasn't always initialized properly in some situations. This
patch initializes that variable. Olaf sent a patch that kzalloc-ed the
data, but this structure is large enough that I would perfer to not do
that. Thanks Olaf!

The reason is that the legacy io check happens very late,
when part of the floppy stuff is already initialized.

southbridge. It is needed in order to use EHCI/USB 2.0 with ACPI.
Without it IRQs are not routed correctly, you get an "Unlink after

The new spinlock debug code turned up a spinlock recursion bug in the
Ethernet gadget driver on a disconnect path; it would show up with any
UDC driver where the cancellation of active requests was synchronous,
rather than e.g. delayed until a controller's completion IRQ.
That recursion is fixed here by creating and using a new spinlock to
protect the relevant lists.

It is supposed to be OK to call mthca_create_ah() and mthca_destroy_ah()
from any context. However, for mem-full HCAs, these functions use the
mthca_alloc() and mthca_free() bitmap helpers, and those helpers use
non-IRQ-safe spin_lock() internally. Lockdep correctly warns that
this could lead to a deadlock. Fix this by changing mthca_alloc() and
mthca_free() to use spin_lock_irqsave().

A recent patch in -mm3 titled
"gregkh-pci-pci-don-t-enable-device-if-already-enabled.patch" causes
pci_enable_device() to be a no-op if the kernel thinks that the device is
already enabled. This change breaks the PCI error recovery mechanism in
the e100 device driver, since, after PCI slot reset, the card is no longer
enabled. This is a trivial fix for this problem. Tested.

The following change from -mm is important to 2.6.18 (actually to 2.6.17
but its too late for that). This was contributed over three months ago
by VIA to Bartlomiej and nothing happened. As a result the new chipset
is now out and Linux won't run on it. By the time 2.6.18 is finalised
this will be the defacto standard VIA chipset so support would be a good
plan.
Tested in -mm for a while, its essentially a PCI ident update but for
the bridge chip because VIA do things in weird ways.
