For each CPU, do the calibration delay only once.  For subsequent calls,
use the cached per-CPU value of loops_per_jiffy.

This saves about 200ms of resume time on dual core Intel Atom N5xx based
systems.  This helps bring down the kernel resume time on such systems
from about 500ms to about 300ms.

Both displays on digsy_mtc board obtain their configuration from microwire
EEPROMs which are connected to the SoC over GPIO lines.  We need an easy
way to access the EEPROMs to write the needed display configuration or to
read out the currently programmed configuration.  The generic
eeprom_93xx46 SPI driver added by previous patch allows EEPROM access over
sysfs.  Using the simple driver added by this patch we provide used GPIO
interface and access control description on the board for generic
eeprom_93xx46 driver and spi_gpio driver.

Add EEPROM driver for 93xx46 chips.  It can also be used with spi_gpio
driver to access 93xx46 EEPROMs connected over GPIO lines.  This driver
supports read/write/erase access to the EEPROM chips over sysfs files.

A common issue with min() or max() is using a cast on one or both of the
arguments when using min_t/max_t could be better.

Add cast detection to uses of min/max and suggest an appropriate use of
min_t or max_t instead.

Caveat:  This only works for min() or max() on a single line.
         It does not find min() or max() split across multiple lines.

This does find:
	min((u32)foo, bar);
But it does not find:
	max((unsigned long)foo,
	    bar);

We presently define all kinds of notifiers in notifier.h.  This is not
necessary at all, since different subsystems use different notifiers, they
are almost non-related with each other.

This can also save much build time.  Suppose I add a new netdevice event,
really I don't have to recompile all the source, just network related.
Without this patch, all the source will be recompiled.

I move the notify events near to their subsystem notifier registers, so
that they can be found more easily.

As stated in drivers/mfd/cs5535-mfd.c, the mfd driver exposes the BARs
which then make the GPIO, MFGPT, ACPI, etc.  all visible to the system.

So the dependencies of the MFGPT stuff have changed, and most people
expect Kconfig to bring in the necessary dependencies.  Without them, the
module fails to load and most people don't understand why because the
details of the rewrite aren't captured anywhere most people who know to
look.

This dependency needs to be reflected in Kconfig.
