Impact: clean up

Impact: cleanup
Use a more generic name - this also allows the prototype to move
to kernel.h and be generally available to kernel developers who
want to do some quick tracing.

Add "disable" module parameter support to ipv6.ko by specifying
"disable=1" on module load. We just do the minimum of initializing
inetsw6[] so calls from other modules to inet6_register_protosw()
won't OOPs, then bail out. No IPv6 addresses or sockets can be
created as a result, and a reboot is required to enable IPv6.

- ide=nodma is no longer valid.
drivers/ide/Kconfig
- The module is ide-core.ko not ide.
drivers/ide/ide.c
- It took me a while to figure out what the arguments %d.%d:%d to nodma
module parameter ment, so I added a comment to each.
- Added a comment to each of the sscanf lines.
- There is a bug, if j is 0 it would previously clear all the other bits
except the current device, changed in three different places.
mask &= (1 << i) should be mask &= ~(1 << i).

The kernel-api docbook was much larger than any of the others,
so processing it took longer and needed some docbook extras in
some cases, so split it into kernel-api (infrastructure etc.)
and device drivers/device subsystems. This allows these docbooks
to be generated in parallel. (This reduced the docbook processing
time on my 4-proc system with make -j4 from about 5min:16sec to
about 2min:01sec.)
The chapters that were moved from kernel-api to device-drivers are:
Driver Basics
Device drivers infrastructure
Parallel Port Devices
Message-based devices
Sound Devices
16x50 UART Driver
Frame Buffer Library
Input Subsystem
Serial Peripheral Interface (SPI)
I2C and SMBus Subsystem

I noticed the old commit 8f5aa26c75
("cpusets: update_cpumask documentation fix") is not a complete fix,
resulting in inconsistent paragraphs. This patch fixes it and does other
fixes and updates:
- s/migrate_all_tasks()/migrate_live_tasks()/
- describe more cpuset control files
- s/cpumask_t/struct cpumask/
- document cpu hotplug and change of 'sched_relax_domain_level' may cause
domain rebuild
- document various ways to query and modify cpusets
- the equivalent of "mount -t cpuset" is "mount -t cgroup -o cpuset,noprefix"

This adds freefall handling to hp_accel driver. According to HP, it
should just work, without us having to set the chip up by hand.
hpfall.c is example .c program that parks the disk when accelerometer
detects free fall. It should work; for now, it uses fixed 20seconds
