aa5372b887 staging: comedi: rtd520: remove RtdAdcClearFifo macro
This macro uses the 'devpriv' macro which relies on a local variable
having a specific name. Plus it's just a wrapper around a simple
'writel'. Remove the macro.

4290cb4bf2 cfg80211: reduce monitor interface tracking
Revert commit b78e8ceac2
("cfg80211: track monitor channel") and remove the
set_monitor_enabled() callback.

Due to the tracking happening in NETDEV_PRE_UP, it had
introduced bugs because the monitor interface callback
would be called before the device was started. It looks
like there's no way to fix this, and using NETDEV_PRE_UP
is broken anyway (since there's no NETDEV_UP_FAIL), so
remove all that code, track interfaces in NETDEV_UP and
also stop tracking the monitor channel in cfg80211.

This mostly reverts to before the tracking, except that
we keep the interface count tracking so that setting the
monitor channel can be rejected properly.

This essentially reverts commit 2e165b8184 but
introduces the get_channel operation with a new
wireless_dev argument so that you can retrieve
the channel per interface. This is necessary as
even though we can track all interface channels
(except monitor) we can't track the channel type
used.

540eb7bf0b net: Update alloc frag to reduce get/put page usage and recycle pages
This patch is meant to help improve performance by reducing the number of
locked operations required to allocate a frag on x86 and other platforms.
This is accomplished by using atomic_set operations on the page count
instead of calling get_page and put_page.  It is based on work originally
provided by Eric Dumazet.

In addition it also helps to reduce memory overhead when using TCP.  This
is done by recycling the page if the only holder of the frame is the
netdev_alloc_frag call itself.  This can occur when skb heads are stolen by
either GRO or TCP and the driver providing the packets is using paged frags
to store all of the data for the packets.

1b820eaf42 ARM: vexpress: Config option for early printk console
Versatile Express platform can be used in different configurations,

addresses in the address space.

This patch makes it possible to select the base address of a PL011
UART to be used as a console output in the kernel configuration.
The default behaviour is still the heuristic detecting memory map
on Cortex-A core tiles.

The zImage decompressor will use the same configuration values
or print out nothing if DEBUG_LL is not enabled.

cd4f2d4aa7 i2c: mxs: Set I2C timing registers for mxs-i2c
This patch configures the I2C bus timing registers according
to information passed via DT. Currently, 100kHz and 400kHz
modes are supported.

The TIMING2 register value is wrong in the documentation for
i.MX28! This was found and fixed by:
