Hello,
this series follows on the discussions of Joonsoo Kim's series
improve robustness on handling migratetype https://lkml.org/lkml/2014/1/9/29
The goal is to close the race of get/set_pageblock_migratetype (and _skip)
which Joonsoo found in the code and I've observed in my further compaction
Joonsoo Kim has found a theoretical race between get/set_pageblock_migratetype
which can result in wrong values being read, including values higher than
MIGRATE_TYPES, thanks to the non-synchronized get/set operations which read or
update individual bits in a loop.
My own testing with a debug
set_pageblock_flags_group() is used to set either migratetype or skip bit of a
pageblock. Setting migratetype is done under zone-lock (except from __init
code), however changing the skip bits is not protected and the pageblock flags
bitmap packs migratetype and skip bits together and uses
Compaction migratepages scanner calls update_pageblock_skip() for blocks where
isolation failed. It currently does that also for blocks where no isolation
was attempted because the skip bit was already set. This is wasteful, so this
patch reuses the existing skipped_async_unsuitable flag to avoid
To prevent races, set_pageblock_migratetype() should be called with zone-lock
held. This patch adds a debugging assertion and introduces a _nolock variant
for zone init functions.

In order to prevent race with set_pageblock_migratetype, most of calls to
get_pageblock_migratetype have been moved under zone-lock. For the remaining
call sites, the extra locking is undesirable, notably in free_hot_cold_page().
This patch introduces a _nolock version to be used on these call
This patch complements the addition of get_pageblock_migratetype_nolock() for
the case where is_migrate_isolate_page() cannot be called with zone-lock held.
A race with set_pageblock_migratetype() may be detected, in which case a caller

The Allwinner A31 has a 16 channels DMA controller that it shares with the
newer A23. Although sharing some similarities with the DMA controller of the
older Allwinner SoCs, it's significantly different, I don't expect it to be
possible to share the driver for these two.
The A31 Controller is
Right now, AHB is an indirect child clock of the CPU clock. If that happens to
change, since the CPU clock has no other consumers declared in Linux, it would
be shut down, which is not really a good idea.
Prevent this by forcing it enabled.

Pens have a special handling in hid-mt as hybrid pen/touch devices
are quite common now. However, some fancy devices presents also
useful collections like mouse or keyboard.
The special case for the pen may not be a special case, and treat it as
a generic case.

Hi guys,
Ok, this patch series is not very consistent and could have been split in two...
Anyway, here is some work for hid-multitouch:
- the first patch is mainly a way for us to reduce the work load regarding
hid-mt
when device makers ask for an inclusion in the kernel.
Also, I have been
The default multitouch protocol class in use since the kernel v3.9 is
working quite well. Since its inclusion, the only devices we had to tweak
were those who really need quirks (GeneralTouch, FocalTech and Wistron,
the 3 of them are Win 7 certified ones).
The flow of new unhandled devices has
The ANTON Touch Pad is a device which can switch from a multitouch
touchpad to a mouse. It thus presents several generic collections which
are currently ignored by hid-multitouch. Enable them by not ignoring
them in mt_input_mapping.
Adding also a suffix for them depending on their application.
Hi,
This patchset adds support for the DMA controller found in the
Allwinner A31 and A23 SoCs.
This has been tested using the newly introduced SPI driver on an A31
EVK. Support for DMA-driven SPI transfers will be the subject of
another patch serie.
Thanks,
Maxime
Changes from v1:
- Removed
Now that we have a DMA driver, we can add the DMA bindings in the DTSI for the
controller and the devices supported that can use DMA.
