Use setup_timer() and instead of init_timer(), being the preferred way
of setting up a timer.
Also, quoting the mod_timer() function comment:
-> mod_timer() is a more efficient way to update the expire field of an
active timer (if the timer is inactive it will be activated).
Use setup_timer() and mod_timer() to setup and arm a timer, making the

we can't rely on the of_xlate() mechanism to initialise things until the
32-bit ARM DMA code learns about groups and default domains, it still
results in a reasonable simplification overall.

At the moment we allocate enough sg table entries assuming we
will not be able to do any coalescing. But since in practice
we most often can, and more so very effectively, this ends up
wasting a lot of memory.
A simple and effective way of trimming the over-allocated
entries is to copy the table over to a new one allocated to the
exact size.
Experiments on my freshly logged and idle desktop (KDE) showed
that by doing this we can save approximately 1 MiB of RAM, or
when running a typical benchmark like gl_manhattan I have
even seen a 6 MiB saving.
More complicated techniques such as only copying the last used
page and freeing the rest are left to the reader.
v2:
* Update commit message.
* Use temporary sg_table on stack. (Chris Wilson)
v3:
* Commit message update.
* Comment added.
* Replace memcpy with copy assignment.

We keep running into cases where device drivers want to know the exact
version of the a SoC they are currently running on. In the past, this has
usually been done through a vendor specific API that can be called by a
driver, or by directly accessing some kind of version register that is
not part of the device itself but that belongs to a global register area
of the chip.
Common reasons for doing this include:
- A machine is not using devicetree or similar for passing data about
on-chip devices, but just announces their presence using boot-time
platform devices, and the machine code itself does not care about the
revision.
- There is existing firmware or boot loaders with existing DT binaries
with generic compatible strings that do not identify the particular
revision of each device, but the driver knows which SoC revisions
include which part.
- A prerelease version of a chip has some quirks and we are using the same
version of the bootloader and the DT blob on both the prerelease and the
final version. An update of the DT binding seems inappropriate because
that would involve maintaining multiple copies of the dts and/or
bootloader.
This patch introduces the soc_device_match() interface that is meant to
work like of_match_node() but instead of identifying the version of a
device, it identifies the SoC itself using a vendor-agnostic interface.
Unlike of_match_node(), we do not do an exact string compare but instead
use glob_match() to allow wildcards in strings.

If soc_device_register() is called before soc_bus_register(), it crashes
with a NULL pointer dereference.
soc_bus_register() is already a core_initcall(), but drivers/base/ is
entered later than e.g. drivers/pinctrl/ and drivers/soc/. Hence there
are several subsystems that may need to know SoC revision information,
while it's not so easy to initialize the SoC bus even earlier using an
initcall.
To fix this, let soc_device_register() register the bus early if that
hasn't happened yet.

drivers/net/xen-netback/xenbus.c:938:3: error: 'err' may be used uninitialized in this function [-Werror=maybe-uninitialized]
This prints it as -EINVAL instead, which seems to be the most
appropriate error code. Before the patch that caused the warning,
this would print a positive number returned by vsscanf() instead,
which is also wrong. We probably don't need a backport though,
as fixing the warning here should be sufficient.
