Hello,
This series adds support for MaxLinear/Exar USB to serial converters.
This driver only supports XR21V141X series but provision has been made
to support other series in future.
This driver is inspired from the initial one submitted by Patong Yang:

__fget_files does check the @f_mode with mask variable and will do some
atomic operations on @f_count while both are on the same cacheline.
Many CPU cores do file access and it will cause much conflicts on @f_count.
If we could make the two members into different cachelines, it

So repeat after me: Bernd's approach _without_ the restart is unacceptable.
It's unacceptable because it breaks things that currently work, and
returns EAGAIN in

Currently perf-stat supports to print counts at regular interval (-I),
but it's not very easy for user to get the overall statistics.
With this patchset, it supports to report the summary at the end of
interval output.
For example,
root@kbl-ppc:~# perf stat -e cycles -I1000 --interval-count 2
It would be useful to support the overall statistics for perf-stat
interval mode. For example, report the summary at the end of
"perf-stat -I" output.
But since perf-stat can support many aggregation modes, such as
--per-thread, --per-socket, -M and etc, we need a solution which
doesn't bring
Currently perf-stat supports to print counts at regular interval (-I),

The patch uses 'evsel->summary_counts' to sum up the per interval counts
and copy the counts to 'evsel->counts' after printing the interval results.
Next, we just
