Remove tuning knobs in /proc/fs/ext4/<dev/* since they have been
replaced by knobs in sysfs at /sys/fs/ext4/<dev>/*.

Add basic sysfs support so that information about the mounted

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.

Fix the mic input of HP dv6736 with Conexant 5051 codec chip.
This laptop seems have no mic-switching per jack connection.
A new model hp-dv6736 is introduced to match with the h/w implementation.

PCI: AMD 813x B2 devices do not need boot interrupt quirk
PCI: Enable PCIe AER only after checking firmware support
PCI: pciehp: Handle interrupts that happen during initialization.
PCI: don't enable too many HT MSI mappings

Added the model=auto to STAC/IDT codecs to use the BIOS default setup
explicitly. It can be used to disable the device-specific model quirk

Documentation/kernel-parameters.txt
- ide=nodma is no longer valid.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).

It's not only useful for the ondemand and conservative governors, but
also for userspace daemons to know about the HW transition latency of
the CPU.
It is especially useful for userspace to know about this value when
the ondemand or conservative governors are run. The sampling rate
control value depends on it and for userspace being able to set sane
tuning values there it has to know about the transition latency.

Some poeple are reading the ext4 feature list too literally and create

then complain when they run into an htree-imposed limit. So add fine

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 8f5aa26c75b7722e80c0c5c5bb833d41865d7019
("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"
