In some SMP systems, cpu-local timers may stop delivering interrupts
when in low power states, or not all CPUs may have local timers. To
support these systems we have a mechanism for broadcasting timer ticks
to other CPUs. This mechanism relies on the struct

This patch adds a check for npct-prcm_base to make sure that the
address is not NULL before using it, as the driver was made capable of
loading even without a proper memory resource in:

Also, refuses to probe without prcm_base on anything

This patch is a v1 based on the RFC submitted here:
https://patchwork.kernel.org/patch/1758921/
This patch set is based on Rui's -thermal tree, and is
tested on a Core-i5 and an Atom netbook.
This series contains 8 patches:
Patch 1/8: Creates new sensor level APIs
Patch 2/8: Creates new zone
This patch creates new APIs to add/remove a
cdev to/from a zone. This patch does not change
the old cooling device implementation.

This patch adds a new thermal_zone structure to
thermal.h. Also, adds zone level APIs to the thermal
framework.
A thermal zone is a hot spot on the platform, which
can have one or more sensors and cooling devices attached
to it. These sensors can be mapped to a set of cooling
devices, which when

This patch creates sensor level APIs, in the
generic thermal framework.
A Thermal sensor is a piece of hardware that can report
temperature of the spot in which it is placed. A thermal
sensor driver reads the temperature from this sensor

To build a proper VDSO for 64 bit and 32 bit from the same source, some
header cleanup is necessary, otherwise a gcc -m32 will produce a lot
of errors and warnings due the differents with LP64 and LP32.

Create a seperate seqcount.h file which handles only seqcount. This file
is save to include in VDSO, since there is no in-kernel functionality
like spinlock in use. seqlock.h still includes seqcount.h, so there is no
side effect for current users.

To make the vsyscall_gtod_data available for both VDSO (X86_64 and
IA32_EMULATION) the alignment must be set to 4. Otherwise the code
create with gcc -m32 will fail, since the structure alignment in 32
bit mode ist 4 byte.

This patch adds support for 32 bit VDSO.
For 32 bit programs running on a 32 bit kernel, the same mechanism is
used as for 64 bit programs running on a 64 bit kernel.
For 32 bit programs running under a 64 bit IA32_EMULATION, it is a

This patch add the functions vdso_gettimeofday(), vdso_clock_gettime()
and vdso_time() to the 32 bit VDSO.
The reason to do this was to get a fast reliable time stamp. Many developers
uses TSC to get a fast time time stamp, without knowing the pitfalls.
