x86: Add support
This patch adds the MSRs and masks for CQM to the x86 uncore.
The actual schedling functions using the MSRs will be included
in the next patch when the new cgroup subsystem is added, as there
are dependencies on structs from the cgroup.

not be a good fit for this data, which does not report on a
per-process level. Therefore, a new cgroup subsystem, cacheqos, has
been added. This operates very similarly to the cpu and cpuacct
cgroup subsystems, where tasks can be grouped into sub-leaves of the
root-level cgroup.

This patch adds the documentation for the new cacheqos cgroup
subsystem. It provides the overview of how the new subsystem
works, how Cache QoS Monitoring works in the x86 architecture,
and how everything is tied together between the hardware and the
cgroup software stack.

The patch also adds the Kconfig option for enabling/disabling the

Hi,
I modified this patch and added the method to igb_get_ts_info function.
For 82576 nic, through this method we can easily check which type of packets
are time stamped now, such as (HWTSTAMP_FILTER_PTP_V1_L4_SYNC and
HWTSTAMP_FILTER_PTP_V1_L4_DELAY_REQ)

Update: Fixed band2queue mapping logic - it was reveresed with prio2band.
Added support in the PRIO qdisc to allow tc to turn on multiqueue behavior,
while keeping original PRIO behavior by default. Fixed where
skb->queue_mapping is be

Documentation is also included describing in more detail how this works, as
wellas how a base driver can use the API to implement multiple queues.

Modified tc so PRIO can now have a multiqueue parameter passed to it. This
will turn on multiqueue behavior if a device has more than 1 queue. Also,
running tc qdisc ls dev will display if multiqueue is on or off.

This patch is *not* intended to be integrated into any tree please. This is
fulfilling a request to demonstrate the proposed multiqueue network device
API in a driver. The necessary updates to the e1000 driver will come in a
more official r
