Dynamically allocate the CPUFreq frequency table on OMAP2xxx chips.
This fixes some compilation problems, since the kernel may not know
what chip it is running on until boot-time. This also reduces the size
of the CPUFreq frequency table.
Problem originally reported by Felipe Balbi <felipe.balbi@nokia.com>.
Thanks also for comments on the patch from Felipe and Kevin.

A subsequent patch adds code on OMAP2xxx to dynamically allocate the
CPUFreq frequency table in clk_init_cpufreq_table(), so for it to
avoid a leak, it will need a corresponding function to free the
memory. This patch adds clk_exit_cpufreq_table() with generic
code to call a chip-specific variant inside the clockfw_lock spinlock via
struct clk_functions.

if we enable CPUFREQ we can't build omap2 for two reasons,
one of them is fixed by the patch below.
It's failing because the __must_be_array() check in
ARRAY_SIZE() is failing and printing the following message:
arch/arm/mach-omap2/clock2xxx.c:453: error: negative width in bit-field '<anonymous>'

Commit 52650505fbf3a6ab851c801f54e73e76c55ab8da added an __initdata
decoration to the structure containing the clk_enable and clk_disable
functions. Once init data was freed, these pointers went to null, and
the next enable or disable call caused the kernel to crash. This
change removes this decoration.

This change adds in some missing clocks that were needed as a result
of 526505... (OMAP1 clock: convert mach-omap1/clock.h to
mach-omap1/clock_data.c). Prior to this, it was just assumed that
these clocks existed for all devices, and it was used directly instead
of calling it out with a clock_get call or similar. So, not having
the CK_7XX meant these clocks weren't being used anymore for omap 7xx
devices, which broke things badly.

The only symbols that should be exported are symbols that are to be
called from loadable kernel modules, e.g., device drivers. In the
context of plat-omap/clock.c, these should only be the Linux clock
interface symbols as defined by include/linux/clk.h. Core code
doesn't need these symbols to be exported. Also, clean up an old
comment while here.

CORE_96M_FCLK

Commit 10db25fea4c11661070b97832b8cc3d2af495092 causes the following

Out of the three major OMAP2 chip types, OMAP2420, OMAP2430, and OMAP3430,
we only map the IVA on OMAP2420. The memory mapping is not shared between
OMAP2420 and OMAP2430, so it is inappropriate to label those macros as
'24XX'; this patch changes them to '2420'.

This fixes a "start_kernel(): bug: interrupts were enabled early".

On Oprofile ARMv7 the PMNC_D bit was set to lower the PMU IRQs
and so to decrease the risk of errata #628216 from appearing.
The effect of setting the PMNC_D bit is that the CCNT counter
is divided by 64, making the program counter events count
inaccurate.
The new OMAP3 r4 cores should have that errata fixed.
The PMNC_D bit should not be set, this patch fixes it.

This avoids races in the VFP code where the dead thread may have
state on another CPU. By moving this code to exit_thread(), we
will be running as the thread, and therefore be running on the
current CPU.
This means that we can ensure that the only local state is accessed
in the thread notifiers.

Add pseudo-DMA by FIQ to the S3C24XX SPI driver. This allows the driver
to get DMA-like performance where there are either no free DMA channels or
when doing transfers that required both TX and RX data paths.
Since this patch requires the addition of an assembly file to hold the FIQ
code, we rename the module (instead of adding a rename of the .c file to
this patch). We expect most users are loading this via udev and thus
there should be no change to the userland configuration.
