Add shadow interrupt-mask register which can be used on SoCs where the
actual hardware register is broken.
Note that some care needs to be taken to make sure the shadow mask

We only need to check if kauditd is valid after we start
it, if kauditd is invalid, we will set kauditd_task to NULL.
So next time, we will start kauditd again.
It means if kauditd_task is not NULL,it must be valid.

Note, if at the same time someone is moving @current to a different

Use css_get/put instead of mem_cgroup_get/put.
We can't do a simple replacement, because here mem_cgroup_put()
is called during mem_cgroup_css_free(), while mem_cgroup_css_free()
won't be called until css refcnt goes down to 0.
Instead we increment css refcnt in mem_cgroup_css_offline(), and

Suppose we rmdir a cgroup and there're still css refs, this cgroup won't
be freed. Then we rmdir the parent cgroup, and the parent is freed due
to css ref draining to 0. Now it would be a disaster if the child cgroup
tries to access its parent.
Make sure this won't happen.

The existing Tegra USB bindings have a few issues:
1) Many properties are documented as being part of the EHCI controller
node, yet they apply more to the PHY device. They should be moved.
2) Some registers in PHY1 are shared with PHY3, and hence PHY3 needs a
reg entry to point at PHY1's register
This patch updates all Tegra board files so that they contain all the
properties required by the updated USB DT binding. Note that this patch
only adds the new properties and does not yet remove the old properties,
in order to maintain bisectability. The old properties will be removed
once the driv

mem_cgroup_css_online calls mem_cgroup_put if memcg_init_kmem
fails. This is not correct because only memcg_propagate_kmem takes an
additional reference while mem_cgroup_sockets_init is allowed to fail as
well (although no current implementation fails) but it doesn't take any
reference. This all su

This reverts commit e4715f01be697a3730c78f8b595591d6a88c
mem_cgroup_put is hierarchy aware so mem_cgroup_put(memcg) already drops
an additional reference from all parents so the additional
mem_cgrroup_put(parent) potentially causes use-after-free.

Registered Tegra USB PHY as a separate platform driver.
To synchronize host controller and PHY initialization, used deferred
probe mechanism. As PHY should be initialized before EHCI starts running,
deferred probe of Tegra EHCI driver till PHY probe gets completed.
Got rid of instance number base
As GPIO information is avail through DT, used it to get Tegra ULPI
reset GPIO number. Added a new member to tegra_usb_phy structure to
store this number.

Fix last ab->phy.notifier call to use vbus_draw as notifier argument, as
that's used in ab8500_charger to control charging current.
Also drop a related TODO comment, and the additional

erratic behaviour of gadget ep0 state machine.

Amend the ab8500-usb driver to optionally take a pin control handle and
set the state of the pins to "default" on ab8500_usb_phy_enable and to
"sleep" on ab8500_usb_phy_disable.
The pinctrl handle is released on ab8500_usb_phy_disable because USB
pins are shared with ab8505

Hello Felipe,
This is the second series of usb updates for Ux500 drivers, covering
almost only ab8500-usb phy.
Patches includes various fixes and errata workarounds, API updates (the
devm_ stuff), and integration with modern subsystems (regulator and
pinctrl).
The whole series has been developed
