This partially reverts one of the changes in an earlier patch,
starting to document where Microsoft's spec is lying.  Needed
to interop with Windows ME.


The Windows ME implementation of RNDIS relies on a message that
Microsoft's specification says isn't used.  Restore this (removed
in earlier cleanup), and start collecting comments specifically
on where MSFT violates its own specifications.

NDIS devices have a generic attribute get/set API where the attributes
are identified by 32 bit "OIDs".  This fixes some problems with the OIDs
supported by the original RNDIS patch:

  - It included OIDs not found in the RNDIS spec.  These have been
    removed.  As a rule, these weren't exported in the "OIDs I support"
    list, and only a couple wouldn't fail those accesses, so this mostly
    changes what debug printk appears.

  - OIDs used for optional 802.3 statistics were partially supported.
    They're all in the OID list now, but the support is #ifdeffed out.
    (Those statistics were mostly just made up, anyway!)

  - "Required" OIDs for suspend, resume, and wakeup support weren't
    listed.  Their messages are now defined, but support is #ifdeffed
    out.  Seems the docs aren't entirely accurate, and Windows can
    behave reasonably without them.  (This area needs help from someone
    who knows MS-Windows power management.)

There are also a few minor cleanups, more reasonable default volume level
for debug messages (never at KERN_INFO, keepalives only if VERBOSE), and
dumping of all bytes of some undocumented messages Windows XP has been
seen emitting shortly before the host suspended itself.

Given the problems that Dan Scholnik has reported, we should combine the
unusual_devs.h entries for the Casio QV cameras into one.  The new
NEED_OVERRIDE flag will prevent complaints about unnecessary overrides,
and Dan says the same subclass and protocol values should work for all the
cameras.  If they don't we'll hear about it soon enough!

The hub driver is very careless about returning resources when an error
occurs while installing a new device.  This patch attempts to put some
order back into the situation.  Details:

	Since usb_new_device() allocates neither the device structure
	nor the device address, it shouldn't release either one.

	Because usb_new_device() no longer releases the device structure,
	usb_register_root_hub() doesn't need to take an extra reference
	to it.

	Since the device address selection and TT setup code is used
	only for new devices, not ones being reset, move that code from
	hub_port_init() to hub_port_connect_change().  By the same token,
	hub_port_init() doesn't have to release the device address or
	the device structure.

	Just to make things look better, move the failure code in
	hub_port_init() to the end of the routine.  And when disabling
	endpoint 0, disable both the IN and OUT parts of the endpoint.

	In hub_port_connect_change(), make all the failure paths
	execute the same code so that resources are always released.
	These resources comprise: the pointer from the parent to the
	new child device, the HCD state for ep0, the device's address,
	and the device structure itself -- in short, everything that's
	set up before calling usb_new_device().

The attached patch enables the pwc driver included with kernel 2.6.7-rc2

It also removes the warnings during compilation.
However, note that I blindly duplicated the release approach used by
other usb camera drivers, replacing the current no-op.

The driver works for me with a Logitech QuickCam Notebook Pro and
GnomeMeeting.

This patch started life from Alan Stern as as274, and has been heavily
modified.  It narrows the case where a clear_halt() is issued after a
failed GetMaxLUN command to only a STALL case.

Since the only legimate responses to a GetMaxLUN are STALL or data,
anything else is now considered a fatal error and we give up on the device.

Ok, here you are! :)
Attached is a patch for linux-2.6.7-rc2. (though the patch hasn't changed
since -rc1)

Again a short description:
(the patch removes most of the changes done in linux-2.6.2)
1. Removed the local buffer of cyberjack_write, because something goes wrong
upon a write-request bigger than the buffer. Without this, a write-request
stalls with error -3.
2. Removed some usb_clear_halt() lines. Without this, the device doesn't even
open and returns -7.

It works for my cyberjack pinpad USB card reader on
- nforce2 chipset
- VIA KM266 chipset
- AMD Irongate chipset

When handling FBIOPUTCMAP_SPARC, sbusfb fails to initialize cmap.transp,
which quickly leads to an oops when fb_set_cmap() dereferences it.

First encountered in Aurora Wombat kernels and seems to afflict mainline
as well. Patch is against 2.6.7-rc2. xorg still fails to actually get
anything to display on my CG6, but at least it no longer oopses the kernel.

This entry in the DMI blacklist table is missing it's NO_MATCH
tags, which means the struct gets padded instead of filled with
the desired NO_MATCH data which is {255, NULL}

Usually not fatal it seems, but there have been numerous cases
in Red Hat bugzilla where this did get tripped up, and caused
an immediate reset on these boards. Not fun to track down.

The recent introduction of ptep_set_access_flags() with the optimisation
of not flushing the TLB unfortunately broke ppc32 CPUs with no hash
table.

The data access exception code path in assembly for these doesn't
properly deal with the case where the TLB entry is present with the
wrong PAGE_RW and will just call do_page_fault again instead of just
replacing the TLB entry.

Fixing the asm code for all the different CPU types affected (yah,
embedded PPCs all have different MMUs =P) is painful and need testing I
can't do at the moment, so here's a fix that will just flush the TLB
page when changing the access flags on non-hash based machines.  Please
apply.

The scheduler changes had another thing missing: the appreciation of
sync wakeups.  (I had this in one of the earlier sched-domains cleanup
patches before but it got lost in the shuffle.)

When a sync waker is waking, we should subtract its load from the
current load - it will schedule away for sure in the near future. 
That's what the "sync" bit means.

This change is necessary because with the sched-domains balancer we have
a much more sensitive cpu-load estimator, and in this particular context
of try_to_wake_up() the sync waker's effect will always be part of the
load.  Patch against your patch attached. 

In my testing there's an additional increase in bw_pipe numbers on a
dual P2 box, it went from 110-120 MB/sec to 120-130 MB/sec.
