When there are multiple L1-aliasing userland mappings of the same physical
page, we currently remap each of them uncached, to prevent VIVT cache
aliasing issues. (E.g. writes to one of the mappings not being immediately
visible via another mapping.)  However, when we do this remapping, there
could still be stale data in the L2 cache, and an uncached mapping might
bypass L2 and go straight to RAM.  This would cause reads from such
mappings to see old data (until the dirty L2 line is eventually evicted.)

This issue is solved by forcing a L2 cache flush whenever the shared page
is made L1 uncacheable.

Ideally, we would make L1 uncacheable and L2 cacheable as L2 is PIPT. But
Feroceon does not support that combination, and the TEX=5 C=0 B=0 encoding
for XSc3 doesn't appear to work in practice.

This patch adds support for the FHCI USB controller, as found
in the Freescale MPC836x and MPC832x processors. It can support
Full or Low speed modes.

Quite a lot the hardware is doing by itself (SOF generation, CRC
generation and checking), though scheduling and retransmission is on
software's shoulders.

This controller does not integrate the root hub, so this driver also
fakes one-port hub. External hub is required to support more than
one device.

My Brother HL-1440 would print one document before CUPS would stop

usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)

In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:

USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

This patch (as1198) fixes a conceptual bug: Somewhere along the line
we managed to confuse USB class devices with USB char devices.  As a
result, the code to send a disconnect signal to userspace would not be
built if both CONFIG_USB_DEVICE_CLASS and CONFIG_USB_DEVICEFS were
disabled.

The usb_fs_classdev_common_remove() routine has been renamed to
usbdev_remove() and it is now called whenever any USB device is
removed, not just when a class device is unregistered.  The notifier
registration and unregistration calls are no longer conditionally
compiled.  And since the common removal code will always be called as
part of the char device interface, there's no need to call it again as
part of the usbfs interface; thus the invocation of
usb_fs_classdev_common_remove() has been taken out of
usbfs_remove_device().

Commit a0d4922d
(USB: fix up suspend and resume for PCI host controllers) attempted
to fix the suspend-resume of PCI USB controllers, but unfortunately
it did that incorrectly and interrupts are left enabled by the USB
controllers' ->suspend_late() callback as a result.  This leads to
serious problems during suspend which are very difficult to debug.

Fix the issue by removing the ->suspend_late() callback of PCI
USB controllers and moving the code from there to the ->suspend()
callback executed with interrupts enabled.  Additionally, make
the ->resume() callback of PCI USB controllers execute
pci_enable_wake(dev, PCI_D0, false) to disable wake-up from the
full power state (PCI_D0).

This patch (as1199) changes the initial wakeup settings for PCI USB
host controllers.  The controllers are marked as capable of waking the
system, but wakeup is not enabled by default.

It turns out that enabling wakeup for USB host controllers has a lot
of bad consequences.  As the simplest example, if a USB mouse or
keyboard is unplugged immediately after the computer is put to sleep,
the unplug will cause the system to wake back up again!  We are better
off marking them as wakeup-capable and leaving wakeup disabled.
