1af5ba514f x86: Clean up and add missing log levels for k8
Convert all printk's in arch/x86/mm/k8topology_64.c to use
pr_info() or pr_err() appropriately.

Adds log levels for messages currently lacking them.

d93a8f829f Revert "USB: Work around BIOS bugs by quiescing USB controllers earlier"
This reverts commit db8be50c43, as per

	http://bugzilla.kernel.org/show_bug.cgi?id=14374
	http://marc.info/?l=linux-kernel&m=125446885705223&w=4

We simply can't do the USB handoff at FIXUP_HEADER time, since it will
often require us to have valid IO mappings etc.  But that in turn
requires a whole different approach, not this trivial one-liner.

Maybe we could teach all the USB quirk handoff handlers to only do the
quirk if the device has all its registers set up (since if it isn't
initialized, it's unlikely to be active), but regardless that will need
a whole lot more code than just saying "let's do it really early".

The proper fix is almost certainly to just leave the legacy IOMMU
mappings active until after all devices have been initialized.

15b812f1d0 pci: increase alignment to make more space for hidden code
As reported in

	http://bugzilla.kernel.org/show_bug.cgi?id=13940

on some system when acpi are enabled, acpi clears some BAR for some
devices without reason, and kernel will need to allocate devices for
them.  It then apparently hits some undocumented resource conflict,
resulting in non-working devices.

Try to increase alignment to get more safe range for unassigned devices.

An interestingly corrupted romfs file system exposed a problem with the
romfs_dev_strnlen function: it's passing the wrong value to its helpers.
Rather than limit the string to the length passed in by the callers, it
uses the size of the device as the limit.

d55500941f USB: ehci: Fix isoc scheduling boundary checking.
The EHCI driver does some bounds checking when it's scheduling an iTD for
an active endpoint.  It sets the local variable start to
stream->next_uframe and moves that variable further in the schedule if
necessary.  However, the driver fails to do anything with start before
jumping to the ready label and setting the URB's starting frame to
stream->next_uframe.  Alan Stern confirms the EHCI driver should set
stream->next_uframe to start before jumping.

f1a0743bc0 USB: storage: When a device returns no sense data, call it a Hardware Error
This patch (as1294) fixes a problem that has plagued users for several
kernel releases.  Some USB mass-storage devices don't return any sense
data when they encounter certain kinds of errors.  The SCSI layer
interprets this to mean that the operation should be retried, and the
same thing happens -- over and over again with no limit.  In some
circumstances (such as when a bus reset occurs) that is the right
thing to do, but not here.

The patch checks for this condition (a transport failure with no sense
data) and changes the result code to DID_ERROR and the sense code to
Hardware Error.  This does get only a limited number of retries, and
so the command will fail relatively quickly instead of getting stuck
in an infinite loop.

This fixes a large part of Bugzilla #14118.

When the host controller dies (e.g. it is removed from a PCI card slot),
the xHCI driver cannot expect commands to complete.  The buggy code this
patch fixes would mark an URB as canceled and then expect the URB to be
completed when the stop endpoint command completed.  That would never
happen if the host controller was dead, so the USB core would just hang in
the disconnect code.

If the host controller died, and the driver asks to cancel an URB, free
any structures associated with that URB and immediately give it back.

cc01f17d5c USB: ftdi_sio: re-implement read processing
- Re-structure read processing.
 - Kill obsolete work queue and always push to tty in completion handler.
 - Use tty_insert_flip_string instead of per character push when
   possible.
 - Fix stalled-read regression in 2.6.31 by using urb status to
   determine when port is closed rather than port count.
 - Fix race with open/close by checking ASYNCB_INITIALIZED in
   unthrottle.
 - Kill private rx_flag and lock and use throttle flags in
   usb_serial_port instead.

e63e278b4d USB: ftdi_sio: clean up read completion handler
Remove superfluous error checks in completion handler:

 - No need to check private data and urb pointers as we check urb-status
   before dereferencing priv (which is not freed until urb has been killed
   on close).
 - No need to check tty as it is checked again when processing.
 - No need to check urb->number_of_packets on bulk urb.

Note that both private data and tty are checked again before processing
(possibly from work queue which also is cancelled on close).
