at91sam9n12 has Full-speed only USB. So we should add
it to the list in at91_pllb_usbfs_clock_init() function.
Moreover, at91sam9n12 has an unusual PMC in the sense that it
has a PLLB but also has a USB clock register.

This will allow me to call functions that have multiple
arguments if fastpath fails. This is required to support ticket
mutexes, because they need to be able to pass an extra argument
to the fail function.
Originally I duplicated the functions, by adding
__mutex_fastpath_lock_retval_arg. This ended up being just a
duplication of the existing function, so a way to test if
fastpath was called ended up being better.
This also cleaned up the reservation mutex patch some by being
able to call an atomic_set instead of atomic_xchg, and making it
easier to detect if the wrong unlock function was previously
used.

Recent Intel CPUs like Haswell and IvyBridge have a new
alternative MSR range for perfctrs that allows writing the full
counter width. Enable this range if the hardware reports it
using a new capability bit.
Currently the perf code queries CPUID to get the counter width,
and sign extends the counter values as needed. The traditional
PERFCTR MSRs always limit to 32bit, even though the counter
internally is larger (usually 48 bits on recent CPUs)
When the new capability is set use the alternative range which
do not have these restrictions.
This lowers the overhead of perf stat slightly because it has to
do less interrupts to accumulate the counter value. On Haswell
it also avoids some problems with TSX aborting when the end of
the counter range is reached.
( See the patch "perf/x86/intel: Avoid checkpointed counters
causing excessive TSX aborts" for more details. )

commit 20d49e9ccfece526db755940721aa13e331936d4
(ARM: OMAP5: voltagedomain data: Add OMAP5 voltage domain data)
Introduced dummy volt data for OMAP5 with OMAP4460 voltage information.
However with the fixes introduced in later patches
commit cd8abed1da91a3250aa4b3857479613a2b446f84
(ARM: OMAP2+: Powerdomain: Remove the need to always have a voltdm
associated to a pwrdm)
We are no longer restricted in that respect. Further, OPP voltage
information is supposed to be provided by dts information. This needs
to be added in future patches as various voltage modules are converted
to dts.
This also fixes the build breakage for voltagedomains54xx_data.c when just
OMAP5 SoC is enabled: https://patchwork.kernel.org/patch/2764191/

The control registers are unsigned long (32 bits on i386, 64 bits on
x86-64), and so make that manifest in the data type for the various
constants. Add defines with a _BIT suffix which defines the bit
number, as opposed to the bit mask.
This should resolve some issues with ~bitmask that Linus discovered.

From Srinivas Kandagatla <srinivas.kandagatla@st.com>:
This patch-set adds basic support for STMicroelectronics STi series SOCs
which includes STiH415 and STiH416 with B2000 and B2020 board support.
STiH415 and STiH416 are dual-core ARM Cortex-A9 CPU, designed for
use in Set-top-boxes. The SOC support is available in mach-sti which
contains support code for STiH415, STiH416 SOCs including the generic
board support.
The reason for adding two SOCs at this patch set is to show that no new
C code is required for second SOC(STiH416) support.

ARM: stih41x: Add B2020 board support

Move the existing clock code in mach-msm to the common clock
framework. We lose our capability to set the rate of and enable a
clock through debugfs. This is ok though because the debugfs
features are mainly used for testing and development of new clock
code.
To maintain compatibility with the original MSM clock code we
make a wrapper for clk_reset() that calls the struct msm_clk
specific reset function. This is necessary for the usb and sdcc
devices on MSM until a better suited API is made available.

With the new default platform code, we can always boot using DT
without requiring a board file, but we cannot build a kernel
unless we select at least one CPU core, which breaks some
"randconfig" builds.
This adapts the ARCH_MULTI_V4T and ARCH_MULTI_V5 options so we
always default to a common CPU core if no platform was enabled
that picks something else. The default we pick for ARMv4T is
ARM920T, while for ARMv5 we pick ARM926T.
