The IRQ handler in omap-i2c.c can sometimes clear status bits without
actually processing them.  In particular, error status bits will be
ignored if any of the ARDY, RRDY, RDR, XRDY, or XDR bits are
concurrently set.

As this code uses unexported symbols, it must be always
built-in. For this reason, a better type of its Kconfig entry
is bool.

Fixed also defconfig which sets this entry as module.

This patch marks several CM register bit fields that are only valid on
3430ES2 and beyond to be 3430ES2 defines.

While we're here, clean up the register defines in cm.h, and improve
documentation slightly.  Also, since CM_AUTOIDLE3 is now in use on
both OMAP24xx and OMAP34xx, remove the platform-specific prefix from
its name.

In OMAP2/3 clock code, we've used mask_to_shift() to convert bitmasks
into shift values, via "ffs(mask) - 1".  It turns out that there is
already a Linux idiom for this in asm/bitops.h: __ffs().  (Not to be
confused with ffs(), of course.  You wouldn't do that, would you?)

When building as a module, the board support code (which is compiled
in) cannot directly call the driver code (which may be in a module.)

platform data.

These changes is the result of the discussion with Paul Walmsley.
His ideas are included into this patch.

Remove DPLL output divider handling from DPLLs and CLKOUTX2 clocks,
and place it into specific DPLL output divider clocks (e.g., dpll3_m2_clk).
omap2_get_dpll_rate() now returns the correct DPLL rate, as represented
by the DPLL's CLKOUT output. Also add MPU and IVA2 subsystem clocks, along
with high-frequency bypass support.

Add support for DPLLs function in locked and bypass clock modes.

Commit a0c1e907 added code to futex.c
to detect whether futex_atomic_cmpxchg_inatomic was implemented at run
time:

+       curval = cmpxchg_futex_value_locked(NULL, 0, 0);
+       if (curval == -EFAULT)
+               futex_cmpxchg_enabled = 1;

This is bogus on parisc, since page zero in kernel virtual space is the
gateway page for syscall entry, and should not be read from the kernel.
(That, and we really don't like the kernel faulting on its own address
 space...)
