Hello, Leon,

Hi everyone,
This patchset adds support for the USB controllers found in the
Allwinner A31.
While the design is similar to the earlier Allwinner SoCs that are
already supported, a few details here and there change, like the fact
that the PHYs now have one clock per phy, while it used to be only
The USB phy controller in the A31 differs mostly from the older controllers
because it has a clock dedicated for each phy, while the older ones were having
a single clock for all the phys.

Being able to show a cpumask of events can be useful as some events
may affect only some CPUs. There is no standard way to record the

the raw event mask and be

That code used to be in the machine code, but it's more fit here with other
restart hooks.
That will allow to cleanup the machine directory, while waiting for a proper
watchdog driver for the A31.

I believe that passing pid (instead of tid) as the 3rd arg of the
machine__find*_thread() was to find a main thread so that it can
search proper map group for symbols. However with the map sharing
patch applied, it now can do it in any thread.
It fixes a bug when each thread has different name,
Memory compaction works by having a "freeing scanner" scan from one end of a
zone which isolates pages as migration targets while another "migrating
scanner"
scans from the other end of the same zone which isolates pages for migration.
When page migration fails for an isolated page, the target
Each zone has a cached migration scanner pfn for memory compaction so that
subsequent calls to memory compaction can start where the previous call left
off.
Currently, the compaction migration scanner only updates the per-zone cached
pfn
when pageblocks were not skipped for async compaction.
Synchronous memory compaction can be very expensive: it can iterate an enormous
amount of memory without aborting, constantly rescheduling, waiting on page
locks and lru_lock, etc, if a pageblock cannot be defragmented.
Unfortunately, it's too expensive for transparent hugepage page faults and
Async compaction terminates prematurely when need_resched(), see
compact_checklock_irqsave(). This can never trigger, however, if the
cond_resched() in isolate_migratepages_range() always takes care of the
scheduling.
If the cond_resched() actually triggers, then terminate this pageblock scan
We're going to want to manipulate the migration mode for compaction in the page
allocator, and currently compact_control's sync field is only a bool.
Currently, we only do MIGRATE_ASYNC or MIGRATE_SYNC_LIGHT compaction depending
on the value of this bool. Convert the bool to enum
Memory migration uses a callback defined by the caller to determine how to
allocate destination pages. When migration fails for a source page, however,
it
frees the destination page back to the system.

Currently perf record doesn't propagate the exit status of a workload
given by the command line. But sometimes it'd useful if it's
propagated so that a monitoring script can handle errors
appropriately.
To do that, it got rid of exit handlers and run/call them directly in
the __cmd_record(). I
The on_exit() function was only used in perf record but it's gone in
previous patch.

The previous patch in the series does:
Optionally push device naming into a function called dynamically by
of_device_alloc().
This patch adds an example of using that capability.

This is a somewhat scary patch since it touches a path that is central to
device creation based on the device tree. It should not be applied without
careful consideration.
I am not sure if this patch is a good idea, even if it does not break
anything.
