The internal interrupts are hardcoded to be level-triggered, but we need
to make sure the OpenPIC code knows that...

The UART tristates its IRQ output when the OUT2 bit in the MCR isn't
set. For reasons not known to civilised man, the hardware engineers
stopped it from floating by pulling it _high_ instead of low, so if
anybody requests that IRQ before OUT2 is turned on, we die in an IRQ
storm. The serial8250 driver does precisely that thing, with precisely
that effect.

ALPHA_KLUDGE_MCR was designed to fix exactly this kind of problem, so we
use it here as intended. Ideally ALPHA_KLUDGE_MCR would go away and be
replaced with something like UPF_FORCE_OUT2 and UPF_FORCE_OUT1 flags,
but now is not the time to get me started on a cleanup of everything
about serial8250 that offends me.

The UART is detected as a ST16650V2 but its FIFO doesn't behave nicely.
Disable autoprobe and hard-code it to be a ST16650 instead.

Just unearthed another of my warcrimes: reading a 17-page sparse file,
I mean holey file, hits the in_interrupt panic in do_exit on a current
highmem kernel (but 2.6.7 is okay).  Fix mismatched preempt count from
shmem_swp_alloc's swapindex hole case by mapping an empty_zero_page.

This fixes two issues in the CFQ IO-scheduler:

o Still a bad allocation under the queue lock
o We need to clear crq after mempool_alloc(), otherwise the rbtree
  pointers can contain garbage if slab poisoning is enabled. This causes
  crashes on front/back merges because rb_next() returns crap.

Don't do partial completions but instead acknowledge already transferred
sectors with verified good status on error.  This allows us to complete
"good" sectors to block layer even if bio they belong to wasn't finished

drive_is_ready() reads STATUS register if CONFIG_IDEPCI_SHARE_IRQ is not
defined and ALTSTATUS register if it is defined.  Therefore drive_is_ready()
in pre_task_mulout_intr() only makes sense if we can't trust STATUS register
(because we call ide_wait_stat() which reads STATUS register earlier).

Remove this "workaround" for now as it is not present in ide-disk.c
and whole multi PIO-out code (CONFIG_IDE_TASKFILE_IO=n) was buggy before.

This patch adds a /block/*/removeable sysfs attribute. A value of 1
indicates the media can change anytime. This is a hint for userland
to poll such devices for possible media changes, and leave all others alone.
There is currently no way to see if a connected usb-storage device is a
disk or a card reader. It will also show 1 for CD and ZIP drives.

It was done by Patrick Mansfield a while ago. I can probably not
sigh-off his work. ;)

Hi again,

Still doing my compile, and got this:

 CC [M]  security/root_plug.o
security/root_plug.c:39: warning: missing initializer
security/root_plug.c:39: warning: (near initialization for `__parm_vendor_id.addr')

Simply upgrading root_plug to use the new module parameter syntax seemed to do
the trick. I made the debug writable, the others just readable to root.

This patch unhides the SMBus on the hp nc8000 and nc6000 laptops. The
patch has been co-written by Jean Delvare and Rudolf Marek. I've only
tested this on nc8000, but it should work for the nc6000 too.

Unfortunatley, we had to little information to fix the problem described
in the reported bug below, as is probably the same problem. But if we're
very lucky it might solve it too.

The hardware vendor, in their infinite wisdom, make the combined

Take this into account.

Obvious bug.  Fixes highmem oops.

This patch marks w9968cf_valid_depth as inline, although it's used
before it's defined.

gcc 3.4 therefore correctly fails with:

<--  snip  -->

This patch moves w9968cf_valid_depth above it's first user (it also uses
two other functions to keep the ordering of functions a bit more
consistent).

Signaling (even D- vs D+ pullup) may not be stable
for a while.

At least one OTG root hub won't reliably (<10%) report device speed until
after reset (and the OTG state transitions have quiesced for a while).

This patch makes that not matter.

This adds some of the infrastructure needed to support some more
USB capabilities:

 -  CONFIG_USB_SUSPEND, so Linux can put individual devices
    into the USB "suspend" state.  They can (sometimes) use
    "remote wakeup" to resume the host; or they can each be
    resumed by the host.

      + New usbcore device selective suspend/resume APIs
	* Define them, as stubs for now
	* Call them on the paths sysfs uses (renamed functions)
      + HCD support
	* Define root hub suspend calls; delegate them to HCDs.
	* OHCI and EHCI can suspend/resume root hubs that way.
	* Not called yet, until suspend/resume calls exist

 -  CONFIG_USB_OTG, which depends on the selective suspend APIs
    to allow devices to switch roles (host to peripheral, etc).
    This patch just adds a few key flags in usb_bus, needed by
    usbcore (during enumeration) and by HCD and OTG controllers
    on OTG-capable boards.

 -  Related bugfix:  power budgeting is supposed to place a
    100mA per port (non-OTG) for bus-powered devices.

This patch changes no behavior; later patches will do that,
and they'll be smaller because of this.
