PCI: Replace HAVE_ARCH_PCI_MWI with PCI_DISABLE_MWI

pSeries is the only architecture left using HAVE_ARCH_PCI_MWI and it's
really inappropriate for its needs.  It really wants to disable MWI
altogether.  So here are a pair of stub implementations for pci_set_mwi
and pci_clear_mwi.

Also rename pci_generic_prep_mwi to pci_set_cacheline_size since that
better reflects what it does.

PCI: Use pci_generic_prep_mwi on sparc64

The setting of the CACHE_LINE_SIZE register in sparc64's pci
initialisation code isn't quite adequate as the device may have
incompatible requirements.  The generic code tests for this, so switch
sparc64 over to using it.

Since sparc64 has different L1 cache line size and PCI cache line size,
it would need to override the generic code like i386 and ia64 do.  We
know what the cache line size is at compile time though, so introduce a
new optional constant PCI_CACHE_LINE_BYTES.

PCI: Use pci_generic_prep_mwi on ia64

The pci_generic_prep_mwi() code does everything that pcibios_prep_mwi()
does on ia64.  All we need to do is be sure that pci_cache_line_size
is set appropriately, and we can delete pcibios_prep_mwi().

Using SMP_CACHE_BYTES as the default was wrong on uniprocessor machines
as it is only 8 bytes.  The default in the generic code of L1_CACHE_BYTES
is at least as good.

PCI: quirks: fix the festering mess that claims to handle IDE quirks

The number of permutations of crap we do is amazing and almost all of it
has the wrong effect in 2.6.

At the heart of this is the PCI SFF magic which says that compatibility
mode PCI IDE controllers use ISA IRQ routing and hard coded addresses
not the BAR values. The old quirks variously clears them, sets them,
adjusts them and then IDE ignores the result.

In order to drive all this garbage out and to do it portably we need to
handle the SFF rules directly and properly. Because we know the device
BAR 0-3 are not used in compatibility mode we load them with the values
that are implied (and indeed which many controllers actually
thoughtfully put there in this mode anyway).

This removes special cases in the IDE layer and libata which now knows
that bar 0/1/2/3 always contain the correct address. It means our
resource allocation map is accurate from boot, not "mostly accurate"
after ide is loaded, and it shoots lots of code. There is also lots more
code and magic constant knowledge to shoot once this is in and settled.

Been in my test tree for a while both with drivers/ide and with libata.
Wants some -mm shakedown in case I've missed something dumb or there are
corner cases lurking.

USB: keep count of unsuspended children

This patch (as818b) simplifies autosuspend processing by keeping track
of the number of unsuspended children of each USB hub.  This will
permit us to avoid a good deal of unnecessary work all the time; we
will no longer have to create a bunch of workqueue entries to carry
out autosuspend requests, only to have them fail because one of the
hub's children isn't suspended.

The basic idea is simple.  There already is a usage counter in the
usb_device structure for preventing autosuspends.  The patch just
increments that counter for every unsuspended child.  There's only one
tricky part: When a device disconnects we need to remember whether it
was suspended at the time (leave the counter alone) or not (decrement
the counter).

USB hub: simplify remote-wakeup handling

This patch (as817) simplifies the remote-wakeup processing in the hub
driver.  Now instead of using a specialized code path, it relies on
the standard USB resume routines.  The hub_port_resume() function does
an initial get_port_status() to see whether the port has already
resumed itself (as it does when a remote-wakeup request is sent).
This will slow down handling of other resume events slightly, but not
enough to matter.

OHCI: make autostop conditional on CONFIG_PM

This patch (as820) makes the root-hub suspend and resume routines
conditional on CONFIG_PM.  It also prevents autostop from activating

EHCI: Fix root-hub and port suspend/resume problems

This patch (as738b) fixes numerous problems in the controller/root-hub
suspend/resume/remote-wakeup support in ehci-hcd:

The bus_resume() routine should wake up only the ports that
were suspended by bus_suspend().  Ports that were already
suspended should remain that way.

The interrupt mask is used to detect loss of power in the
bus_resume() routine (if the mask is 0 then power was lost).
However bus_suspend() always sets the mask to 0.  Instead the
mask should retain its normal value, with port-change-detect
interrupts disabled if remote wakeup is turned off.

The interrupt mask should be reset to its correct value at the
end of bus_resume() regardless of whether power was lost.

bus_resume() reinitializes the operational registers if power
was lost.  However those registers are not in the aux power
well, hence they can lose their values whenever the controller
is put into D3.  They should always be reinitialized.

When a port-change interrupt occurs and the root hub is
suspended, the interrupt handler should request a root-hub
resume instead of starting up the controller all by itself.

There's no need for the interrupt handler to request a
root-hub resume every time a suspended port sends a
remote-wakeup request.

The pci_resume() method doesn't need to check for connected
ports when deciding whether or not to reset the controller.
It can make that decision based on whether Vaux power was
maintained.

Even when the controller does not need to be reset,
pci_resume() must undo the effect of pci_suspend() by
re-enabling the interrupt mask.

If power was lost, pci_resume() must not call ehci_run().
At this point the root hub is still supposed to be suspended,
not running.  It's enough to rewrite the command register and
set the configured_flag.

Certain boards seem to like to issue false overcurrent notifications, for
example on ports that don't have anything connected to them.  This looks
like a hardware error, at the level of noise to those ports' overcurrent
input signals (or non-debounced VBUS comparators).  This surfaces to users
as truly massive amounts of syslog spam from khubd (which is appropriate
for real hardware problems, except for the volume from multiple ports).

Using this new "ignore_oc" flag helps such systems work more sanely, by
preventing such indications from getting to khubd (and spam syslog).  The
downside is of course that true overcurrent errors will be masked; they'll
appear as spontaneous disconnects, without the diagnostics that will let
users troubleshoot issues like short circuited cables.

Note that the bulk of these reports seem to be with VIA southbridges, but

usb: writing_usb_driver free urb cleanup

Allright. As Greg KH suggested I split this big patch into smaller ones to
make the changes easier to review. Having no better idea how to split that I
split it on a 'patch per file' basis. All those patches clean redundant 'if' before
usb_unlink/free/kill_urb():

if (urb)
usb_free_urb(urb); /* unlink / free / kill */

I decided not to touch bigger 'if's like

if (urb) {
usb_kill_urb(urb);
usb_free_urb(urb);
urb = NULL;
}

as that would be probably too intrusive. One of patches also fixes
drivers/usb/misc/auerswald.c memleak I found when digging the code. All those
patches are against 2.6.19-rc4.

USB: expand autosuspend/autoresume API

API.  It also provides convenient wrapper routines,
usb_autopm_enable() and usb_autopm_disable(), for drivers that want
to specify directly whether autosuspend should be allowed.

USB: autosuspend code consolidation

This patch (as813) gathers together common code for USB interface
autosuspend/autoresume.

It also adds some simple checking at the time an autosuspend request
is made, to see whether the request will fail.  This way we don't
add a workqueue entry when it would end up doing nothing.

USB: makes usb_endpoint_* functions inline.

We have no benefits of having the usb_endpoint_* functions as functions,
but making them inline saves text and data segment sizes:

text    data     bss     dec     hex filename
14893634 3108770 1108840 19111244 1239d4c vmlinux.func
14893185 3108566 1108840 19110591 1239abf vmlinux.inline

 This is the result of a 2.6.19-rc3 kernel compiled with GCC 4.1.1 without
CONFIG_MODULES, CONFIG_CC_OPTIMIZE_FOR_SIZE, CONFIG_REGPARM options set.
USB support is fully enabled (while most of the other drivers are not),
and that kernel has most of the USB code ported to use the endpoint
functions.

That happens because a call to those functions are expensive (in terms
of bytes), while the function's size is smaller or have the same 'size' of
the call.
