This adds the core function pnp_dbg() and a new config option to
enable it.
The PNP core debugging messages can be enabled at boot-time with the
"pnp.debug" kernel parameter.

lenb: Note that overriding a critical trip point
may simply fool the user into thinking that they
have control that they do not actually have.
For it is EC firmware that decides when the EC
sends Linux temperature change events, and the
EC may or may not decide to send Linux these events
anywhere in the neighborhood of the fake
override trip points. Beware.
note also that thermal.nocrt is already available
to disable crtical trip point actios,
and thermal.crt=-1 is already available to
disabled critical trip points entirely.

transition
Maybe the incorrect power state is returned on the bogus bios, which
is different with the real power state. For example: the bios returns D0
state and the real power state is D3. OS expects to set the device to D0
state. In such case if OS uses the power state returned by the BIOS and
checks the device power state very strictly in power transition, the device
can't be transited to the correct power state.
So the boot option of "acpi.power_nocheck=1" is added to avoid checking
the device power in the course of device power transition.

The document describing how to port i2c chip drivers from Linux 2.4 to
Linux 2.6 is outdated. As I suspect that most drivers that had to be
ported have already been by now, I do not want to spend time updating
it. Let's just delete it instead.

This adds relocatable kernel support for kdump. With this one can
use the same regular kernel to capture the kdump. A signature (0xfeed1234)
is passed in r6 from panic code to the next kernel through kexec_sequence
and purgatory code. The signature is used to differentiate between
kdump kernel and non-kdump kernels.
The purgatory code compares the signature and sets the __kdump_flag in
head_64.S. During the boot up, kernel code checks __kdump_flag and if it
is set, the kernel will behave as relocatable kdump kernel. This kernel
will boot at the address where it was loaded by kexec-tools ie. at the
address reserved through crashkernel boot parameter.
CONFIG_CRASH_DUMP depends on CONFIG_RELOCATABLE option to build kdump
kernel as relocatable. So the same kernel can be used as production and
kdump kernel.
This patch incorporates the changes suggested by Paul Mackerras to avoid
GOT use and to avoid two copies of the code.

The current MSI-HOWTO.txt says that device drivers should not request the
memory space that contains MSI-X tables. This is because the original
MSI-X implementation did a request_mem_region() on this space, but that
code was removed long ago (in the pre-git era, in fact). Years after the
code was changed, we might as well clean up the documention to avoid a
confusing mention of requesting regions: drivers using MSI-X can just use
pci_request_regions() just like any other driver, and so there's no need
for MSI-HOWTO.txt to talk about this at all.

Since the code is shared pretty much most of the pci= options are shared,
but kernel-parameters.txt marked most of them as i386 only.

Only accept dynids whose driver_data value matches one of the driver's
pci_driver_id entries. This prevents the user from accidentally passing
values the drivers do not expect.

UBIFS read performance can be improved by skipping the CRC
check when data nodes are read. This option can be used if
the underlying media is considered to be highly reliable.
Note that CRCs are always checked for metadata.
Read speed on Arm platform with OneNAND goes from 19 MiB/s
to 27 MiB/s with data CRC checking disabled.

Some flash media are capable of reading sequentially at faster rates.
UBIFS bulk-read facility is designed to take advantage of that, by
reading in one go consecutive data nodes that are also located
consecutively in the same LEB.
Read speed on Arm platform with OneNAND goes from 17 MiB/s to
19 MiB/s.
