PCI: use _CRS for PCI resource allocation
Use _CRS for PCI resource allocation
This patch resolves an issue where incorrect PCI memory and i/o ranges
are being assigned to hotplugged PCI devices on some IBM systems. The
resource mis-allocation not only makes the PCI device unuseable but
often makes the entire system unuseable due to resulting machine checks.
The hotplug capable PCI slots on the affected systems are not located
under a standard P2P bridge but are instead located under PCI root
bridges or subtractive decode P2P bridges. For example, the IBM x3850
contains 2 hotplug capable PCI-X slots and 4 hotplug capable PCIe slots
with the PCI-X slots each located under a PCI root bridge and the PCIe
slots each located under a subtractive decode P2P bridge.
The current i386/x86_64 PCI resource allocation code does not use _CRS
returned resource information. No other resource information source is
available for slots that are not below a standard P2P bridge so
incorrect ranges are being allocated from e820 hole causing the bad
result.
This patch causes the kernel to use _CRS returned resource info. It is
roughly based on a change provided by Matthew Wilcox for the ia64 kernel
in 2005. Due to possible buggy BIOS factor and possible yet to be
discovered kernel issues the function is disabled by default and can be
enabled with pci=use_crs.

PCI: avoid P2P prefetch window for expansion ROMs
Avoid creating P2P prefetch window for expansion ROMs
Because of the future possibility that P2P prefetch windows will contain
address ranges above 4GB some BIOSes are providing space in the P2P
non-prefetch windows for expansion ROMs. This is due to expansion ROM
BAR 32-bit limitation. When expansion ROM BARs without BIOS assigned
address(es) are currently found behind a P2P bridge, the kernel attempts
to create a P2P prefetch window for them even though space for them has
already been provided in the non-prefetch window. _CRS on some systems
with certain resource conservation conscious BIOSes may not provide the
extra 1MB or more memory resource needed for the expansion ROM motivated
prefetch window causing resource allocation errors.
This change corrects the problem by removing IORESOURCE_PREFETCH from
the expansion ROM flags initialization. It also removes
IORESOURCE_CACHEABLE which seems inappropriate if only non-cacheable
memory is available.

i386: add support for picopower irq router
Add support for PicoPower PT86C523 IRQ router to be used with the in-kernel
yenta driver for CardBus. With this patch cardbus works on e.g. Dell
Latitude XPi P150CD.
Initial patch for kernel 2.4 series by Sune Mølgaard
http://molgaard.org/code/linux-2.4.31-picopower.patch
Ported to 2.6.20 by Chmouel Boudjnah (http://www.chmouel.com)
Testing and confirmation that it works by Austin Acton
Cleaned up a little for inclusion in a 2.6.21-rc7 based kernel.
Added some more cleanups according to CodingStyle, as noted by
Randy Dunlap on LKML.

dma_free_coherent() needs irqs enabled (sigh)
On at least ARM (and I'm told MIPS too) dma_free_coherent() has a newish
call context requirement: unlike its dma_alloc_coherent() sibling, it may
not be called with IRQs disabled. (This was new behavior on ARM as of late
2005, caused by ARM SMP updates.) This little surprise can be annoyingly
driver-visible.
Since it looks like that restriction won't be removed, this patch changes
the definition of the API to include that requirement. Also, to help catch
nonportable drivers, it updates the x86 and swiotlb versions to include the
relevant warnings. (I already observed that it trips on the
bus_reset_tasklet of the new firewire_ohci driver.)

Fix a longstanding race in the Ethernet gadget driver, which can cause an

whether its freelist is empty. That check is otherwise not necessary,
since the queue is always stopped when that list empties (and restarted
when request completion puts an entry back on that freelist).
The race window starts when the network code decides to transmit a packet,
and ends when hard_start_xmit() grabs the freelist lock. When disconnect()
is called inside that window, it shuts down the TX queue and breaks the
otherwise-solid assumption that packets are never sent through a TX queue
that's stopped.

USB: Driver for CH341 USB-serial adaptor
This patch implements a USB serial port driver for the Winchiphead
CH341 USB-RS232 Converter. This chip also implements an IEEE 1284
parallel port, I2C and SPI, but that is not supported by the driver.

USB: cxacru: Use appropriate logging for errors
When an error occurs, existing logging uses dbg() so the cause of a
problem is hard to determine. Error conditions shouldn't only be
properly reported with debugging enabled.
A side effect of this change is that when an uninitialised device is
started, a log message similar to the following is sent:
cxacru 5-2:1.0: receive of cm 0x90 failed (-104)
This is normal - the device did not respond so firmware will be loaded.

USB: remove USB_QUIRK_NO_AUTOSUSPEND
This patch (as995) cleans up the remains of the former NO_AUTOSUSPEND
quirk. Since autosuspend is disabled by default, we will let
userspace worry about which devices can safely be suspended. Thus the
lengthy series of quirk entries is no longer needed, and neither is
the quirk ID. I suppose someone might eventually run across a hub
that can't be suspended; let's ignore the possibility for now.
The patch also cleans up the hasty way in which autosuspend gets
disabled. Setting udev->autosuspend_delay to -1 wasn't quite right,
because the value is always supposed to be a multiple of HZ. It's
better to leave the delay value alone and set autosuspend_disabled,
which is what the quirk routine used to do.

USB: fix limited_power setting mistake in hub.c
This patch (jx001) fixes a variable assignment mistake in hub driver.
limited_power should be set to 0 if the hub is self-powered,and 1 if
the hub is bus-powered.
However, the effect of the code was exactly opposite to the spec's
statement for the Local Power Source field. The spec says, this field
is 1 meaning Local power supply lost while this field is 0 indicating
Local power supply good.(This statement is very confusing.)
So this patch switchs the 0 and 1.

USB: usb-skeleton leaking locks on open
This weekend I was hacking around with a trivial USB driver for talking
to the boot load firmware of a USB Bit Whacker. It's running the
MicroChip Pic18 boot loader firmware and I'm putting together a flash
program for writing new FW to the thing.
Anyway in my use of the usb-skeleton.c as my starting point I discovered
my test program was getting hung up after attempting to write a buffer.
The application and driver where hung in a way that required me to
reboot to get it to clean up so I could try again.
It turned out the code path through skel_open can grap the driver's
io_mutex lock and forget to release it.
The following patch fixes the problem for me.

USB: flush outstanding URBs when suspending
This patch (as989) makes usbcore flush all outstanding URBs for each
device as the device is suspended. This will be true even when
CONFIG_USB_SUSPEND is not enabled.
In addition, an extra can_submit flag is added to the usb_device
structure. That flag will be turned off whenever a suspend request
has been received for the device, even if the device isn't actually
suspended because CONFIG_USB_SUSPEND isn't set.
It's no longer necessary to check for the device state being equal to
USB_STATE_SUSPENDED during URB submission; that check can be replaced
by a check of the can_submit flag. This also permits us to remove
some questionable references to the deprecated power.power_state field.

USB: break apart flush_endpoint and disable_endpoint
This patch (as988) breaks usb_hcd_endpoint_disable() apart into two
routines. The first, usb_hcd_flush_endpoint() does the -ESHUTDOWN
unlinking of all URBs in the endpoint's queue and waits for them to
complete. The second, usb_hcd_disable_endpoint() -- renamed for
better grammatical style -- merely calls the HCD's endpoint_disable
method. The changeover is easy because the routine currently has only
one caller.
This separation of function will be exploited in the following patch:
When a device is suspended, the core will be able to cancel all
outstanding URBs for that device while leaving the HCD's
endpoint-related data structures intact for later.
As an added benefit, HCDs no longer need to check for existing URBs in
their endpoint_disable methods. It is now guaranteed that there will
be none.

USB: move decision to ignore FREEZE events

them for non-root devices is pushed down into the USB-device driver,
instead of being made in the core code.
This is appropriate, since devices exported to a virtualized guest or
over a network may indeed need to handle these types of suspend, even
though normal devices don't.
