Specifications state that the MAP packet length in the MAP header do
not account for the number of bytes of packet trailer from DL checksum
offload. Current implementation takes this into account for data
packets but not for command packets. As a result, the additional
8 bytes were sent to hardware as part of the MAP ACK's and were
subsequently dropped.
Fix this by truncating the extra bytes of the DL checksum trailer from

Currently stop_hwmon only releases the perf events for each CPU
in the memlat device group. This leaves out the perf_event_attrs
that are not needed anymore leading to memory leaks.
This patch frees perf_event_attrs right after the perf events are
created because they are copied into the perf_event structure
when it is created for a particular event and hence do not need
to exist beyond that point.

If any of the CPUs monitored by a memlat device is offline while
trying to register for perf events, the registration fails
returning an error code to the governor's start_monitor function
which then fails the setting of governor and leaves the system in
a bad state.
To avoid this scenario, this patch allows for initialization errors
while registering for perf events and remembers the failing offline
CPUs. Perf event registration is tried for the failing CPUs when they
come back online. Once all the CPUs have registered for perf events
hotplug notifiers callbacks are unregistered.

When doing over-voting due to an UP_WAKE event, the governor
pre-initialized the max_mbps value for the next decision window. This was
done to prevent a dropping the vote below the original measurement in case
a DOWN_WAKE event comes before the decision window is complete. This has
the undesirable side-effect of keeping the votes high for two decision
windows following an UP_WAKE event.
Also, DOWN_WAKE event is currently disabled for any decision windows that
didn't do over-voting because doing so had significant performance impacts.
However, with historic max tracking, pattern detection and hysteresis, and
mbps zones awareness that were added later on, the above concerns aren't
really valid anymore. So, simply delete the pre-initialization of the
max_mbps so that one decision window isn't unnecessarily voting higher than
necessary. As part of the change, also fix down_cnt logic to allow it to
work for all decision windows if enabled.
