Doing access control checks with rq_lock held can cause deadlock when
audit messages are created (via printk or audit infrastructure) which
trigger a wakeup and deadlock, as noted by both SELinux and SubDomain
folks.  This patch will let the security checks happen w/out lock held,
then re-sample the p->policy in case it was raced. 

Originally from John Johansen <johansen@immunix.com>, reworked by me.
AFAIK, this version drew no objections from Ingo or Andrea.

The recent patch to scrub out ep0 state earlier (to get rid of some of
the enumeration problems that started with about 2.6.6) requires EHCI
to handle endpoint_disable() calls in a slightly different context.

This makes those calls work when an endpoint's QH may still be on the
async schedule, rather than already unlinked.  (The QH stays on the async
schedule for a few milliseconds after it's empty, since it's routine to
issue another request almost immediately.)

This has minor PCI tweaks for the EHCI driver:

  - If the (nonfunctional) AMD 8111 controller shows up, ignore it.
    (Patch from Matt Dharm, with minor coding style tweaks).

  - Delete some code that interprets an EHCI capability code; it
    should be a PCI capability instead.

This patch implements the Windows scheme for USB device initialization.
It also incorporates the change recently posted by David to scrub the
endpoint state following a SET-ADDRESS.  Other noteworthy changes:

	There are two new module parameters to control whether the
	old scheme or the new one is used first and whether the other
	scheme is tried if the first one fails.  Default settings are
	to use the new scheme only.

	hub_set_address() returns 0 immediately if the device is already
	in the USB_STATE_ADDRESS state.

	On the first attempt to read the device descriptor the code
	uses a short 1-second timeout.  This ought to help prevent
	full-speed devices with an 8- or 16-byte maxpacket from
	slowing the procedure down by NAKing the unexpectedly early
	status stage of the transfer.

	For debugging, the ep0 maxpacket value is printed.  It might
	be a good idea to validate it rather than just believing the
	device -- although I haven't heard of any device providing
	an incorrect value other than 0.

This didn't show up in my "allmodconfig" tests, because the
console requires things to be built-in, not modules.

Posix timers preallocate siqueue structures during timer creation
and keep them for reuse.  This allocation happens in user context
with no locks held, however it's designated as an atomic allocation.
Loosen this restriction, and while we're at it let's do a bit of code
consolidation so signal sending uses same __sigqueue_alloc() helper.
