Introduce a new function map_gicc_mpidr() to allow MPIDRs to be obtained
from the GICC Structure introduced by ACPI 5.1.
The ARM architecture defines the MPIDR register as the CPU hardware
identifier. This patch adds the code infrastructure to retrieve the MPIDR
values from the ARM ACPI GICC

It'd be great to get these patches upstream for v4.1 via the MIPS tree

Hi Thomas, Ingo,
this pull request provides the following fixes for 4.0-rc1:
- Fix the Kconfig to prevent the asm9260 timer to be compiled with
allyesconfig with sparc/sparc64 (Daniel Lezcano)
- Reorder the mtk driver init sequence in order to prevent a potential
race when the clock is
From: Robert Jarzmik
As pxa_timer_common_init() is only called in init context, mark it as
such, and quiesce the compiler warnings :
WARNING: vmlinux.o(.text.unlikely+0x45d4): Section mismatch in reference
from the function pxa_timer_common_init() to the function

You're really operating on old information.
From: Matthias Brugger
We have two race conditions in the probe code which could lead to a null
pointer dereference in the interrupt handler.
The interrupt handler accesses the clockevent device, which may not yet be
registered.
First race condition happens when the interrupt handler gets

The Kconfig options for the asm9260 timer is wrong as it can be selected by
another platform with allyes config and thus leading to a compilation failure
as some non arch related code is pulled by the compilation.
Fix this by having the platform Kconfig to select the timer as it is done for

As preparation work for the introduction of an eFuse subsystem,
this commit moves Tegra's fuse header and fixes the includes
where needed.

The soc/tegra/fuse.h header makes use of kernel-specific types (u32, u8) and
therefore it needs a linux/types.h include.

Now that the efuse subsystem has been introduced, move the Tegra efuse driver
from drivers/soc/tegra/fuse/ to drivers/efuse/tegra. For now, there's no
generic efuse API. However, by having the drivers in a unified location it is
expected that such API will arise easier once support for more
This patchset introduces a new driver subsystem, meant to support eFuse
(alias OTP, one-time-programmable) devices.
The motivation behind this work is to have a common place for drivers
that are currently more or less scattered: the tegra efuses are in
drivers/soc/ and the sunxi efuses in

This commit introduces a new eFuse subsystem stub to hold all the eFuse-like
device drivers. This will be used to host the currently supported Tegra
eFuse driver, and will allow to add support for other platforms as well.

After the introduction of the efuse subsystem, platforms are now required
to select the efuse support explicitly.

The Sunxi SoC eFuse support is currently located under drivers/eeprom,
although the driver is not an eeprom. This commit just moves the driver
to drivers/efuse. There's no functionality change.
