This reverts a recent change to usb_set_interface(). The change worked
around a quirk in certain devices, but doing this in usbcore creates
needless regressions for other devices. More appropriate fixes won't
put such handling in usbcore.
Basically it's tricky to do a full software reset of USB device state, since
the devices don't all act the same. This adds a note to the kerneldoc for
the usb_reset_configuration() call to highlight the quirk this was working
around: endpoint data toggles not being reset.

This patch includes minor "sparse -Wbitwise" updates for the PCI based
HCDs. Almost all of them involve just changing the second parameter of the
suspend() method to a pm_message_t ... the others relate to how the EHCI
code walks in-memory data structures. (There's a minor bug fixed there too
... affecting the big-endian sysfs async schedule dump.)

===================================================================
This is the first of a few installments of PM API updates to match the
recent switch to "pm_message_t". This installment primarily affects
USB device drivers (for USB interfaces), and it changes the handful of
drivers which currently implement suspend methods:
- <linux/usb.h> and usbcore, signature change
- Some drivers only changed the signature, net effect this just
shuts up "sparse -Wbitwise":
* hid-core
* stir4200
- Two network drivers did that, and also grew slightly more
featureful suspend code ... they now properly shut down
their activities. (As should stir4200...)
* pegasus
* usbnet
Note that the Wake-On-Lan (WOL) support in pegasus doesn't yet work; looks
to me like it's missing a request to turn it on, vs just configuring it.
The ASIX code in usbnet also has WOL hooks that are ready to use; untested.

This has a variety of updates to the shared suspend/resume code for
PCI based USB host controllers.
- Cope with pm_message_t replacing the target system state.
This is actually a loss of functionality; PCI D1 and D2
states will no longer be used, and it's no longer knowable
that D3cold is on the way so power will be lost.
- Most importantly, some of the resume paths are reworked and
cleaned up. They're now an exact mirror of suspend paths,
and more care is taken to ensure the hardware is reactivated
before the hardware re-enables interrupts.
Plus comment and diagnostic cleanups; there are some nasty cases here
especially combined with swsusp, now they're somewhat commented.

Don't use cmd->request->nr_hw_segments as it may not be initialized
(SG_IO in particular bypasses anything that initializes this and just
uses scsi_do_req to insert a scsi_request directly on the head of the
queue) and a bogus value here can trip up the checks to make sure that
the number of segments will fit in the queue ring buffer, resulting in
commands that are never completed.
Fix up several issues with PCI DMA mapping and failure to check return
values on the mappings.
Make the check for space in the ring buffer happen after the DMA mapping
is done since any checks done before the mapping has taken place are
bogus.

This adds 32-bit compatibility for mounting an NFSv4 mount on a 64-bit
kernel (such as happens with PPC64).
The problem is that the mount data for the NFS4 mount process includes
auxilliary data pointers, probably because the NFS4 mount data may
conceivably exceed PAGE_SIZE in size - thus breaking against the hard
limit imposed by sys_mount().

This fixes a deadlock on the dcache lock detected during testing at IBM
by moving the logging of the current executable information from the
SELinux avc_audit function to audit_log_exit (via an audit_log_task_info
helper) for processing upon syscall exit.
For consistency, the patch also removes the logging of other
task-related information from avc_audit, deferring handling to
audit_log_exit instead.
This allows simplification of the avc_audit code, allows the exe
information to be obtained more reliably, always includes the comm
information (useful for scripts), and avoids including bogus task
information for checks performed from irq or softirq.

We were flushing the D-cache excessively for ptrace() processing
and this makes debugging threads so slow as to be totally unusable.
All process page accesses via ptrace() go via access_process_vm().
This routine, for each process page, uses get_user_pages(). That
in turn does a flush_dcache_page() on the child pages before we
copy in/out the ptrace request data.
Therefore, all we need to do after the data movement is:
1) Flush the D-cache pages if the kernel maps the page to a different
color than userspace does.
2) If we wrote to the page, we need to flush the I-cache on older cpus.
Previously we just flushed the entire cache at the end of a ptrace()
request, and that was beyond stupid.

SunOS aparently had this weird PTRACE_CONT semantic which
we copied. If the addr argument is something other than
1, it sets the process program counter to whatever that
value is.
This is different from every other Linux architecture, which
don't do anything with the addr and data args.
This difference in particular breaks the Linux native GDB support
for fork and vfork tracing on sparc and sparc64.
There is no interest in running SunOS binaries using this weird
PTRACE_CONT behavior, so just delete it so we behave like other
platforms do.
