Description: Bug 387 (http://bugzilla.kernel.org/show_bug.cgi?id=387)
is fixed by the attached patch, which sends waitqueue wake-ups to all
the appropriate wait-queue entries when a device is removed from
the system.

This patch provides a new "sl811-hcd" driver, which should replace the older
one from Cypress (which has been broken for ages, even on SA-1100).

Key features of this new driver:

 - Small, relatively tight code;
 - Uses the 2.6 platform_device and usbcore HCD infrastructures;
 - Compiles (x86, ARM) and works (ARM/PXA255);
 - Passed a day's worth of "usbtest" stress testing (on 2.6.9).

I've enumerated over a dozen different devices with it, and actually tested
mice, hubs, keyboards, and usb-storage.  There's a hardware erratum that
prevents this chip from working with certain external hubs.  There's scope
yet for some performance work here; and some IRQ quirks linger.

This PIO-only driver should serve as a model for some other non-DMA USB host
controllers (like isp1161, isp1362, td243) used in embedded Linuxes ... in
particular, showing how to maintain async and periodic schedules without
pointless emulation of OHCI DMA queues and/or registers.

The driver should handle ISO, but since it doesn't implement the special
urb->iso_frame_desc[] "pseudo-queue" model (and since Linux can't guarantee
low enough IRQ latencies!), ISO is disabled.

I noticed an SMP deadlock when connecting devices to
an autosuspended root hub.

This fix just makes the OHCI hub status reporting logic (used
exclusively by khubd) be a NOP until after the worker task
(keventd) finishes resuming the port, so they can't deadlock.

This makes the EHCI driver stop trying to update a live QH ... it's
not like OHCI, that can't be done safely because of a hardware race.
The fix:

    - Unlinks the QH before updating it; only the tail can safely be
      updated "live", not the queue head.  The async schedule (all
      control/bulk QHs) and periodic schedule (interrupt QH) work a
      bit differently ... high bandwidth transfers will hiccup.

    - Moves "update QH" and "clear toggle" logic into one new
      qh_refresh() routine, used in several places.

The race shows readily enough under load with the right hardware.
The controller silicon might be relatively slow, or maybe it's the
bus that's slow/busy:

	Host			Controller
	---			----------
				reads two TD pointers
	update two TD pointers
	wmb()
	activate QH
				reads rest of QH

Net result is that the HC treated old TD pointers as valid, and things
started misbehaving.  Busy controllers would misbehave worse; some systems
wouldn't notice more than a slowdown, especially with light USB loads.

This affects behavior in two cases.  The uncommon one is when an endpoint
gets an error and halts.  The more common one happens when the controller
runs off the end of its queue and overlays an inactive "dummy" TD into
the QH ... something the spec says shouldn't happen, but which more
silicon seems to be doing.  (Presumably to reduce DMA chatter.)

This patch fixes two small problems in the port suspend/resume handling
for the UHCI driver.  There were a couple of spots where I neglected to
store I/O addresses in unsigned _long_ variables (required for 64-bit
architectures).  And it turns out the host controller will continue to
indicate a resume is in progress for a few microseconds after it has been
turned off, so an extra delay is needed.

We were using 0x08000000 instead of TASK_UNMAPPED_BASE
so that running something like "/lib/ld-linux.so.2 emacs"
would work.

The issue there was that wherever /lib/ld-linux.so.2 gets
mapped (controlled by ELF_ET_DYN_BASE), that is where the
BSS start for the process ends up.  Now, emacs allocates
dynamic memory for LISP objects from the BSS, and needs
the top 4 bits of the virtual address to be clear so that
it can encode LISP type and GC marking information there.

But making this obscure emacs case work breaks lots of other
stuff.  For example, programs with a reasonably large data
section fail to load via direct ld.so interpreter execution
because the data section is large enough to begin overlapping
with the ELF_ET_DYN_BASE area.

The /lib/ld-linux.so.2 emacs case does not work on a lot of
platforms due to this issue, including i386, so it is not
worth making work on sparc either.  It is indeed useful
sometimes when debugging a new experimental build of glibc
for example, but people doing that can hack the value of
ELF_ET_DYN_BASE in their kernels.  Perhaps at some point
we will make a sysctl controllable value.

This patch fixes an oops when the ipt action is used with a
non-existant iptables target. It tries to log
t->u.kernel.target->name, u.kernel.target is part of a union
and as long as the target wasn't successfully loaded contains
the name of the target, using it as a pointer results in a
crash.
