Al Viro did this for x86-64 and reduced the number of dependencies on
sched.h significantly. We had a couple of files which were relying on
uaccess.h pulling in sched.h, so they need explicit dependencies added.

* add ide_use_fast_pio() helper for use by host drivers
* add DMA capability and hwif->autodma checks to ide_use_dma()
- au1xxx-ide/it8213/it821x drivers didn't check for (id->capability & 1)
[ for the IT8211/2 in SMART mode this check shouldn't be made but since
in it821x_fixups() we set DMA bit explicitly:
if(strstr(id->model, "Integrated Technology Express")) {
/* In raid mode the ident block is slightly buggy
We need to set the bits so that the IDE layer knows
LBA28. LBA48 and DMA ar valid */
id->capability |= 3; /* LBA28, DMA */
we are better off using generic helper if we can ]
- ide-cris driver didn't set ->autodma
[ before the patch hwif->autodma was only checked in the chipset specific
hwif->ide_dma_check implementations, for ide-cris it is cris_dma_check()
function so there no behavior change here ]

* updated patch description (thanks to Alan Cox for the feedback)

I added two fields to struct usb_serial_port to keep track of the
throttle state. Other usb-serial drivers typically use private data for
such things, but the generic driver can not really do that because some
of its code is also used by other drivers (which may have their own
private data needs).
As it is, I am not sure that this patch is useful in all scenarios.
It is certainly helpful for low-bandwidth devices that can hold their
data in response to throttling. But for devices that pump data in
real-time as fast as possible (webcam, A/D converter, etc), throttling
may actually cause more data loss.

Add function of_get_mac_address(), which obtains the best MAC address to use
from the device tree by checking various properties in order. The order is:
'mac-address', then 'local-mac-address', then 'address'. It skips properties
that contain invalid MAC addresses, which were probably not initialized
by U-Boot.
Update gfar_of_init() and fs_enet_of_init() in fsl_soc.c to call
of_get_mac_address().

On recent systems, calls to /sbin/modprobe are handled by udev depending
on the kind of device the kernel has discovered. This patch creates an
uevent for the kernels internal request_module(), to let udev take control
over the request, instead of forking the binary directly by the kernel.
The direct execution of /sbin/modprobe can be disabled by setting:
/sys/module/kmod/mod_request_helper (/proc/sys/kernel/modprobe)
to an empty string, the same way /proc/sys/kernel/hotplug is disabled on an
udev system.

Extend rdma_cm to support multicast communication. Multicast support
is added to the existing RDMA_PS_UDP port space, as well as a new
RDMA_PS_IPOIB port space. The latter port space allows joining the
multicast groups used by IPoIB, which enables offloading IPoIB traffic
to a separate QP. The port space determines the signature used in the
MGID when joining the group. The newly added RDMA_PS_IPOIB also
allows for unicast operations, similar to RDMA_PS_UDP.
Supporting the RDMA_PS_IPOIB requires changing how UD QPs are initialized,
since we can no longer assume that the qkey is constant. This requires
saving the Q_Key to use when attaching to a device, so that it is
available when creating the QP. The Q_Key information is exported to
the user through the existing rdma_init_qp_attr() interface.
Multicast support is also exported to userspace through the rdma_ucm.

The IB SA tracks multicast join/leave requests on a per port basis and
does not do any reference counting: if two users of the same port join
the same group, and one leaves that group, then the SA will remove the
port from the group even though there is one user who wants to stay a
member left. Therefore, in order to support multiple users of the
same multicast group from the same port, we need to perform reference
counting locally.
To do this, add an multicast submodule to ib_sa to perform reference
counting of multicast join/leave operations. Modify ib_ipoib (the
only in-kernel user of multicast) to use the new interface.
