This patch replaces the empty AMD vPMU functions (in pmu_amd.c) with real
implementation.

This patch defines a new function pointer struct (kvm_pmu_ops) to
support vPMU for both Intel and AMD. The functions pointers defined in
this new struct will be linked with Intel and AMD functions later. In the
meanwhile the struct that maps from event_sel bits to PERF_TYPE_HARDWARE
events is renamed and moved from Intel specific code to kvm_host.h as a
common struct.

Commit edafc132ba ("xen-netback: making the bandwidth limiter runtime settable")
introduced the capability to change the bandwidth rate limit at runtime.
But it also introduced a possible crashing bug.
If netback receives two XenbusStateConnected without getting the
hotplug-status watch firing in between, then it will try to register the
watches for the rate limiter again. But this triggers a BUG() in the watch
registration code.
The fix modifies connect() to remove the possibly existing packet-rate
watches before trying to install those watches. This behaviour is in line
with how connect() deals with the hotplug-status watch.

When STP is running in user-space and querier is configured, the
querier timer is not started when a port goes to a non-blocking state.
This patch unifies the user- and kernel-space stp multicast port enable
path and enables it in all states different from blocking. Note that when a
port goes in BR_STATE_DISABLED it's not enabled because that is handled
in the beginning of the port list loop.

Actor and Partner details can be accessed via proc-fs, sys-fs
entries or netlink interface. These interfaces are world readable
at this moment. The earlier patch-series made the LACP communication
secure to avoid nuisance attack from within the same L2 domain but
it did not prevent "someone unprivileged" looking at that information
on host and perform the same act.
This patch essentially avoids spitting those entries if the user
in question does not have enough privileges.

The commit 898b2970e2 ("mvneta: implement SGMII-based in-band link state
signaling")
changed mvneta_adjust_link() so that it does not clear the auto-negotiation
bits in MVNETA_GMAC_AUTONEG_CONFIG register. This was necessary for
auto-negotiation mode to work.
Unfortunately I haven't checked if these bits are ever initialized.
It appears they are not.
This patch adds the missing initialization of the auto-negotiation bits
in the MVNETA_GMAC_AUTONEG_CONFIG register.
It fixes the following regression:
https://www.mail-archive.com/netdev@vger.kernel.org/msg67928.html
Since the patch was tested to fix a regression, it should be applied to
stable tree.
