7ac72746aa ARM: dts: Revert disabling of smc91x for n900
Revert "ARM: dts: Disable smc91x on n900 until bootloader
dependency is removed". We've now fixed the issues that
caused problems with uninitialized hardware depending on
the bootloader version. Mostly things got fixed with
the following commits:

9a894953a9 ("ARM: dts: Fix bootloader version dependencies by muxing n900 smc91x pins")
7d2911c438 ("net: smc91x: Fix gpios for device tree based booting")

Note that this only affects the early development boards
with Ethernet that we still have in a few automated boot
test systems. And it's also available supposedly in some
versions of qemu.

3ec72fabcc clk: sunxi: Propagate rate changes to parent for mux clocks
The cpu clock on sunxi machines is just a mux clock, which is normally
fed by the main PLL, but can be muxed to the main or low power oscillator.

Make the mux clock propagate rate changes to its parent, so we can
change the clock rate of the PLL, and thus actually implement rate
changing on the cpu clock.

This patch also removes the no reparenting limit.

6810e4a394 percpu_ref: remove unnecessary ACCESS_ONCE() in percpu_ref_tryget_live()
__ref_is_percpu() needs the implied ACCESS_ONCE() in
lockless_dereference() on @ref->percpu_count_ptr because the value is
tested for !__PERCPU_REF_ATOMIC, which may be set asynchronously, and
then used as a pointer.  If the compiler generates a separate fetch
when using it as a pointer, __PERCPU_REF_ATOMIC may be set in between
contaminating the pointer value.

percpu_ref_tryget_live() also uses ACCESS_ONCE() to test
__PERCPU_REF_DEAD; however, there's no reason for this.  I just copied
ACCESS_ONCE() usage blindly from __ref_is_percpu().  All it does is
confusing people trying to understand what's going on.

This patch removes the unnecessary ACCESS_ONCE() usage from
percpu_ref_tryget_live() and adds a comment explaining why
__ref_is_percpu() needs it.

a1eb03f546 virtio_pci: document why we defer kfree
The reason we defer kfree until release function is because it's a

63bd62a08c virtio_pci: defer kfree until release callback
A struct device which has just been unregistered can live on past the
point at which a driver decides to drop it's initial reference to the
kobject gained on allocation.

This implies that when releasing a virtio device, we can't free a struct
virtio_device until the underlying struct device has been released,
which might not happen immediately on device_unregister().

Unfortunately, this is exactly what virtio pci does:
it has an empty release callback, and frees memory immediately
after unregistering the device.

This causes an easy to reproduce crash if CONFIG_DEBUG_KOBJECT_RELEASE
it enabled.

To fix, free the memory only once we know the device is gone in the release
callback.

7a9f0604bd ARM: dts: imx51-babbage: Fix ULPI PHY reset modelling
GPIO2_5 is the reset GPIO for the USB3317 ULPI PHY. Instead of modelling it as
a regulator, the correct approach is to use the 'reset_gpios' property of the
"usb-nop-xceiv" node.

GPIO1_7 is the reset GPIO for the USB2517 USB hub. As we currently don't have
dt bindings to describe a HUB reset, let's keep using the regulator approach.

Rename the regulator to 'reg_hub_reset' to better describe its function and bind
it with the USB host1 port instead.

USB host support has been introduced by commit 9bf206a9d1 ("ARM: dts:
imx51-babbage: Add USB Host1 support"), which landed in 3.16 and it seems that
USB has only been functional due to previous bootloader initialization.

With this patch applied we can get USB host to work without relying on the
bootloader.

9d31b3ce81 batman-adv: fix potential TT client + orig-node memory leak
This patch fixes a potential memory leak which can occur once an
originator times out. On timeout the according global translation table
entry might not get purged correctly. Furthermore, the non purged TT
entry will cause its orig-node to leak, too. Which additionally can lead
to the new multicast optimization feature not kicking in because of a
therefore bogus counter.

In detail: The batadv_tt_global_entry->orig_list holds the reference to
the orig-node. Usually this reference is released after
BATADV_PURGE_TIMEOUT through: _batadv_purge_orig()->
batadv_purge_orig_node()->batadv_update_route()->_batadv_update_route()->
batadv_tt_global_del_orig() which purges this global tt entry and
releases the reference to the orig-node.

However, if between two batadv_purge_orig_node() calls the orig-node
timeout grew to 2*BATADV_PURGE_TIMEOUT then this call path isn't
reached. Instead the according orig-node is removed from the
originator hash in _batadv_purge_orig(), the batadv_update_route()
part is skipped and won't be reached anymore.

Fixing the issue by moving batadv_tt_global_del_orig() out of the rcu
callback.
