"Pick the default arch depending on the target size" in binutils repo)
31 bit builds will fail since the linker would now try to create 64 bit

Fix this by setting OUTPUT_ARCH to s390:31-bit instead of s390.

Here's the first set of fixes for v3.7-rc cycle.
DesignWare Core USB3 Driver (dwc3) got two fixes. The first one fixes a long
standing bug which would keep endpoint with BUSY flag set forever if we cancel
a transfer which has already been started by the controller. The second fix
will just switch PHYs back off when DWC3 driver is removed.
MUSB fixed a bug which would cause a Kernel Oops at least on AM3517 when
removing a device. For some reason that particular device can fall into a
situation where you have both Disconnect and Endpoint IRQs happen
simultaneously (have both bits set in IRQ_STATUS register) and, because
Disconnect Interrupt is handled before Endpoint Interrupts, we would try to
transfer data over a disconnected device, thus generating a kernel oops.
Renensas' USB DRD driver got two fixes which are a) fixing an off-by-one bug on
the pipe iterator implementation and b) fixing Interrupt Status Clear procedure
in order to properly clear a single Interrupt event without clearing (and
masking) other events we didn't handle yet.

The PERF_EVENT_IOC_PERIOD ioctl command can be used to change the

previous one has overflowed.
This patch changes the calculation of the remaining event ticks so that
they are offset if the period has changed.

Earlier without cpuidle framework on pseries, the native arch
idle routine comprised of both snooze and nap
states. smt_snooze_delay variable was used to delay
the idle process entry to deeper idle state like nap.
With the coming of cpuidle, this arch specific idle was replaced
by two different idle routines, one for supporting snooze and other
for nap. This enabled addition of more
low level idle states on pseries in the future.
On adopting the generic cpuidle framework for POWER systems,
the decision of which idle state to choose from, given a predicted
idle time is taken by the menu governor based on
target_residency and exit_latency of the idle states.
target_residency is the minimum time to be resident in that idle state.
Exit_latency is time taken to exit out of idle state.
Deeper the idle state, both the target residency and exit latency
would be higher.
In the current design, smt_snooze_delay is used as target_residency
for the snooze state which is incorrect, as it is not the
minimum but the maximum duration to be in snooze state.
This would result in the governor in taking bad decision,
as presently target_residency of nap < target_residency of snooze
inspite of nap being deeper idle state.
This patch aims to fix this problem by replacing the smt_snooze_delay loop
in snooze state, with the need_resched() as the governor is aware of
entry and exit of various idle transitions based on which
next idle time prediction.
The governor is intelligent enough to determine the idle state the needs to
be transitioned to and maintains a whole of heuristics including
io load, previous idle states predictions etc for the same, based on
which idle state entry decision is taken.
With this fix, of setting target_residency of snooze to 0
nap to smt_snooze_delay
if the predicted idle time is less
than smt_snooze_delay (target_residency of nap)
value governor would pick snooze state, else nap. This adhers to the
previous native idle design.

smt_snooze_delay was designed to delay idle loop's nap entry
in the native idle code before it got ported over to use as part of
the cpuidle framework.
A -ve value assigned to smt_snooze_delay should result in
busy looping, in other words disabling the entry to nap state.
- https://lists.ozlabs.org/pipermail/linuxppc-dev/2010-May/082450.html
This particular functionality can be achieved currently by
echo 1 > /sys/devices/system/cpu/cpu*/state1/disable
but it is broken when one assigns -ve value to the smt_snooze_delay
variable either via sysfs entry or ppc64_cpu util.
This patch aims to fix this, by disabling nap state when smt_snooze_delay
variable is set to -ve value.

Remove the redundant target residency initialisation in pseries_cpuidle_driver_init().
This is currently over-writing the residency time updated as part of the static
table, resulting in all the idle states having the same target
residency of 100us which is incorrect. This may result in the menu governor making
wrong state decisions.

The previous definition of for_each_*() would always include the very
first object within the list, irrespective of whether it was marked
deleted, since the deleted flag was not checked on the first object,
but only on any "next" object.
Fix for_each_*() to check the deleted flag in the loop body every
iteration to correct this.
