When parsing PnP ACPI resource structures, it may happen that some of
the resources are disabled (in which case "the size" of the resource
equals zero).

The current solution is to skip these resources completely - with the
unfortunate side effect that they are not registered despite the fact
that they exist, after all.  (The downside of this approach is that
these resources cannot be used as templates for setting the actual
device's resources because they are missing from the template.) The
kernel's APM implementation does not suffer from this problem and
registers all resources regardless of "their size".

This patch fixes a problem with (at least) the vintage IBM ThinkPad 600E
(and most likely also with the 600, 600X, and 770X which have a very
similar layout) where some of its PnP devices support options where
either an IRQ, a DMA, or an IO port is disabled.  Without this patch,
the devices can not be configured using the
"/sys/bus/pnp/devices/*/resources" interface.

The manipulation of these resources is important because the 600E has
very demanding requirements.  For instance, the number of IRQs is not
sufficient to support all devices of the 600E.  Fortunately, some of the
devices, like the sound card's MPU-401 UART, can be configured to not
use any IRQ, hence freeing an IRQ for a device that requires one.
(Still, the device's "ResourceTemplate" requires an IRQ resource
descriptor which cannot be created if the resource has not been
registered in the first place.)

As an example, the dependent sets of the 600E's CSC0103 device (the
MPU-401 UART) are listed, with the patch applied, as:

  Dependent: 00 - Priority preferred
    port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding
    irq <none> High-Edge
  Dependent: 01 - Priority acceptable
    port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding
    irq 5,7,2/9,10,11,15 High-Edge

(The same result is obtained when PNPBIOS is used instead of PnP ACPI.)
Without the patch, the IRQ resource in the preferred option is not
listed at all:

  Dependent: 00 - Priority preferred
    port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding
  Dependent: 01 - Priority acceptable
    port 0x300-0x330, align 0xf, size 0x4, 16-bit address decoding
    irq 5,7,2/9,10,11,15 High-Edge

And in fact, the 600E's DSDT lists the disabled IRQ as an option, as can
be seen from the following excerpt from the DSDT:

	Name (_PRS, ResourceTemplate ()
	{
        StartDependentFn (0x00, 0x00)
        {
            IO (Decode16, 0x0300, 0x0330, 0x10, 0x04)
            IRQNoFlags () {}

With this patch applied, a user space program - or maybe even the kernel
- can allocate all devices' resources optimally.  For the 600E, this
means to find optimal resources for (at least) the serial port, the
parallel port, the infrared port, the MWAVE modem, the sound card, and
the MPU-401 UART.

The patch applies the idea to register disabled resources to all types
of resources, not just to IRQs, DMAs, and IO ports.  At the same time,
it mimics the behavior of the "pnp_assign_xxx" functions from
"drivers/pnp/manager.c" where resources with "no size" are considered
disabled.

No regressions were observed on hardware that does not require this
patch.

The patch is applied against 2.6.39.

NB: The kernel's current PnP interface does not allow for disabling individual
resources using the "/sys/bus/pnp/devices/$device/resources" file.  Assuming
this could be done, a device could be configured to use a disabled resource
using a simple series of calls:

  echo disable > /sys/bus/pnp/devices/$device/resources
  echo clear > /sys/bus/pnp/devices/$device/resources
  echo set irq disabled > /sys/bus/pnp/devices/$device/resources
  echo fill > /sys/bus/pnp/devices/$device/resources
  echo activate > /sys/bus/pnp/devices/$device/resources

This patch addresses only the parsing of PnP ACPI devices.

ChangeLog (v1 -> v2):
 - extend patch description
 - fix typo in patch itself

We forget to save the return value of the call to
twl_rtc_write_u8(save_control, REG_RTC_CTRL_REG); in 'ret', making the
test of 'ret < 0' dead code since 'ret' then couldn't possibly have
changed since the last test just a few lines above.  It also makes us not
detect failures from that specific twl_rtc_write_u8() call.

Add support for PMIC8xxx based RTC.  PMIC8xxx is Qualcomm's power
management IC that internally houses an RTC module.  This driver
communicates with the PMIC module over SSBI bus.

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.

driver to access 93xx46 EEPROMs connected over GPIO lines.  This driver
supports read/write/erase access to the EEPROM chips over sysfs files.

Previous behavior allowed only alphabetic prefixes like pr_info to exceed
the 80 column line length limit.

ath6kl wants to add a digit into the prefix, so allow numbers as well as
digits in the <prefix>_<level> printks.

<prefix>_<level>_ratelimited and <prefix>_<level>_once and WARN_RATELIMIT

Some users would like the ability to not emit some of the messages that
checkpatch produces.  This can make it easier to use checkpatch in other
projects and integrate into scm hook scripts.

Add command line option to "--ignore" various message types.  Add option
--show-types to emit the "type" of each message.  Categorize all ERROR,
WARN and CHK messages with types.

Add optional .checkpatch.conf file to store default options.
3 paths are searched for .checkpatch.conf
    .             customized per-tree configurations
    $HOME         user global configuration when per-tree configs don't exist
    ./scripts     lk defaults to override script
The .conf file can contain any valid command-line argument and
the contents are prepended to any additional command line arguments.
Multiple lines may be used, blank lines are ignored, # is a comment.

Update "false positive" output for readability.
