Add a helper routine returning the lowest power (highest number) ACPI device
power state that given device can be in while the system is in the sleep state
indicated by acpi_target_sleep_state .

In the future some drivers may need to use ACPI to determine the low power
states in which to place their devices, but to provide the drivers with this
information the ACPI core needs to know what sleep state the system is going to
enter. Namely, the device's state should not be too high power for given system
sleep state and, if the device is supposed to be able to wake up the system, its
state should not be too low power for the wake up to be possible). For this
purpose, the ACPI core needs to implement the set_target() method in 'struct
pm_ops' and store the target system sleep state passed by the PM core in a
variable.

For NUMA emulation, our SLIT should represent the true NUMA topology of the
system but our proximity domain to node ID mapping needs to reflect the
emulated state.
When NUMA emulation has successfully setup fake nodes on the system, a new
function, acpi_fake_nodes() is called. This function determines the proximity
domain (_PXM) for each true node found on the system. It then finds which
emulated nodes have been allocated on this true node as determined by its
starting address. The node ID to PXM mapping is changed so that each fake
node ID points to the PXM of the true node that it is located on.
If the machine failed to register a SLIT, then we assume there is no special
requirement for emulated node affinity so we use the default LOCAL_DISTANCE,
which is newly exported to this code, as our measurement if the emulated nodes
appear in the same PXM. Otherwise, we use REMOTE_DISTANCE.
PXM_INVAL and NID_INVAL are also exported to the ACPI header file so that we
can compare node_to_pxm() results in generic code (in this case, the SRAT
code).

When making changes to x86_64 timers, I noticed that touching hpet.h triggered

In acpi_scan_nodes(), we immediately return -1 if acpi_numa <= 0, meaning
we haven't detected any underlying ACPI topology or we have explicitly
disabled its use from the command-line with numa=noacpi.
acpi_table_print_srat_entry() and acpi_table_parse_srat() are only
referenced within drivers/acpi/numa.c, so we can mark them as static and
remove their prototypes from the header file.
Likewise, pxm_to_node_map[] and node_to_pxm_map[] are only used within
drivers/acpi/numa.c, so we mark them as static and remove their externs
from the header file.
The automatic 'result' variable is unused in acpi_numa_init(), so it's
removed.

Fixes STN LCD support for the atmel_lcdfb framebuffer driver.
This patch is the result of a work from Jan Altenberg and has
been tested on a Hitachi SP06Q002 on at91sam9261ek.
It adds a Kconfig switch that enables the proper LCD in the
board configuration file (STN or TFT). The switch is used
in arch/arm/mach-at91/at91sam9261_devices.c & board-sam9261ek.c
as an example.
This patch includes the "Fix wrong line_length calculation"
little one from Jan and Haavard (submitted earlier).
AT91 platform informations are directly submitted trough
the at91 maintainer, here :

This patch adds support for the Simtek STK17TA8 timekeeping chip.
The STK17TA8 is quite similar to the DS1553, but differs in register layout
and in various control bits in the registers. I chose to make this a new
driver to avoid confusion in the code and to not get lost in #ifdefs.

Various people have expressed surprise that their modular RTC drivers don't
seem to work for initializing the system time at boot. To help avoid such
unpleasantness, make the Kconfig text point out that the driver probably
needs to be statically linked.
