ARM: tegra: Handle timers during LP2 idle ticks

Timer ticks aren't properly serviced while a CPU is in LP2 idle.
Although the Tegra LP2 idle code calls hrtimer_peek_ahead_timers,
because no IRQ regs have been saved, update_process_times is not
called, and thus the timer list is not serviced (and neither is
SMP rebalancing, etc.)  This can cause significant delays
scheduling timer-based activity, especially on CPU 1 (which is
not servicing most other IRQs).

Colin Cross suggested a patch based on upstream review feedback
that uses clock notifiers to switch to the "broadcast" clock event
source ("timer0" Tegra timer 3) during LP2, which has a real
interrupt handler defined that calls the clock event handler in
IRQ context, allowing timers to be checked.

USB: ehci: tegra: Align DMA transfers to 32 bytes

The Tegra2 USB controller doesn't properly deal with misaligned DMA

network adapters, where skbuff alignment is often in the middle of a

USB: HCD: Add driver hooks for (un)?map_urb_for_dma

Provide optional hooks for the host controller driver to override the

be necessary unless the host controller has special DMA requirements,
such as alignment contraints.  If these are not specified, the
general usb_hcd_(un)?map_urb_for_dma functions will be used instead.
Also, pass the status to unmap_urb_for_dma so it can know whether the
DMA buffer has been overwritten.

Finally, add a flag to be used by these implementations if they
allocated a temporary buffer so it can be freed properly when unmapping.

ARM: tegra: clock: Save and restore plld, plls, and pllu in suspend

HDMI was not working after LP0 because the plld were being reset
during suspend.  plls and pllu were also not being saved.  Add
all three to tegra_clk_suspend.

The lock time for plld is 1000 us, so increase the delay after
setting the PLLs.

Add a BUG_ON to ensure the size of the suspend context area is
correct.

Originally fixed by Mayuresh Kulkarni.

13 years agocgroup: leave cg_list valid upon cgroup_exit

cgroup: leave cg_list valid upon cgroup_exit

A thread/process in cgroup_attach_task() could have called
list_del(&tsk->cg_list) after cgroup_exit() had already called
list_del() on the same list. Since it only checked for
!list_empty(&tsk->cg_list) before doing this, the list_del()
call would thus be made twice.

The solution is to leave tsk->cg_list in a valid state in
cgroup_exit() with list_del_init(&tsk->cg_list), which leaves
an empty list.

rtc: alarm: Update hrtimer if alarm at the head of the queue is reprogrammed

If an alarm was restarted with a value that moved it away from the head
of a queue, the hrtimer would not be updated. This would cause unnecessary
wakeups.
