Michal,
Here is the official pull-request for the kconfig-related changes I've
gathered from the linux-kbuild list, and those I've locally accumulated,
for inclusin in 3.10:
- memory leak fixed in mconf
- 3 randconfig fixes (randomising choices, setting tristates,
Recent gcc's may place functions into the .text.unlikely section and we
need to check this section as well for section mismatches now otherwise
we may have false negatives for this test.

Changing the retry to start at NFS4_POLL_RETRY_MIN and exponentially grow
to NFS4_POLL_RETRY_MAX allow for faster handling of these error conditions.
Additionally this alleviates an interoperability problem with the AIX NFSv4

here is a last minute revert from the GPIO tree. Description in the

The Timer Pulse Unit (TPU is a 4-channels 16-bit timer used to generate
waveforms. This driver exposes PWM functions through the PWM API for
other drivers to use.
The code is loosely based on the leds-renesas-tpu driver by Magnus Damm

Hello,
This is the second version of the Renesas TPU PWM unit support patches. The
patch series deprecates and removes the leds-renesas-tpu driver in favor of a
combination of leds-pwm and pwm-rmob. As an added bonus patches 9/11 and 10/11
remove function GPIOs support from the sh73a0 platform.
The flat panel backlight on the Armadillo 800 EVA board is driven by the
TPU PWM output.

Dear RT Folks,
I'm pleased to announce the 3.2.43-rt63-feat1 feature release.
This release contains the backport of the softirq routines being called
directly by the thread that raised the softirq, making the softirq run
at the priority of its caller. Special thanks goes out to Sebastian

the writeback bit is still required and not setting it in this case was

Hi all,
I've noticed that sometimes lockdep would spew a warning and an oops
while dumping the list of held locks. I'm not quite sure why it happens
and I didn't find anything that was recently changed in the code that
could cause that:

Add a new 'smp_init' hook to machine_desc so platforms can specify a
function to be used to setup smp ops instead of having a statically
defined value. The hook must return true when smp_ops are initialized.
If false the static mdesc->smp_ops will be used by default.
Rename virt_smp_ops to psci_smp_ops and move them to arch/arm/kernel/psci_smp.c.
Remove mach-virt/platsmp.c, now unused.
Compile psci_smp if CONFIG_ARM_PSCI and CONFIG_SMP.
Add a cpu_die smp_op based on psci_ops.cpu_off.
Initialize PSCI before setting smp_ops in setup_arch.
Use psci_smp_ops if
Hi all,
this is the eighth version of the patch series to move virt_smp_ops out
of mach-virt and make it a generic set of reusable PSCI based smp_ops.
psci_smp_ops are preferred over the platform smp_ops.
The last patch introduces smp_init.

Kay Sievers noted that the ALWAYS_USE_PERSISTENT_CLOCK config,

For boards that provide a PCB sensor close to SoC junction
temperature, it is possible to remove the cumulative heat
reported by the SoC temperature sensor.
This patch changes the extrapolation computation to consider
an external sensor in the extrapolation equations.

Hello Greg,
Here are two patches on ti-soc-thermal driver.
One is to update the documentation of the OMAP5430 DT entry reference.
The other one adds the support to extrapolation rules with PCB sensor
querying. The second one depends on the API change, that is going
via the thermal tree [1].

Ugh.. powerpc probably has CONFIG_ISA_DMA_API but not
CONFIG_VIRT_TO_BUS.
I'm looking for a fix now.

Applied to x86/vt-d, thanks.
