if we fail with ERESTARTSYS during alloc, we'll get a retry from
userspace so don't report it in dmesg.

Do as we did before rework, if no placement is supplied at bo
creation time, fallback to allocating bo from system ram. This
will fix most of the creation failed issue report we got since
the rework get merged.

1) The function was previously called with a potentially empty
LRU list which would have lead to an OOPS or servere corruption.
2) In rare cases, after reservation has succeeded, another process may
already have evicted it or even pinned it. We must revalidate the
buffer status after releasing the lru lock.

1) Remove from lru before reserving so we avoid competing with

commit 654d1f8a019dfa06d (packet: less dev_put() calls)
introduced a problem, calling potentially sleeping functions from a
rcu_read_lock() protected section.
Fix this by releasing lock before the sock_wmalloc()/memcpy_fromiovec() calls.
After skb allocation and copy from user space, we redo device
lookup and appropriate tests.

Add the basic ALSA mixer functionality. The mixer is event-driven,
and will work fine on IBM ThinkPads. I expect Lenovo ThinkPads will
cause some trouble with the event interface.
Heavily based on work by Lorne Applebaum <lorne.applebaum@gmail.com>
and ideas from Matthew Garrett <mjg@redhat.com>.

Disable volume control by default. It can be enabled at module load
time by a module parameter (volume_control=1).
The audio control mixer that thinkpad-acpi interacts with is fully
functional without any drivers, and operated by hotkeys.
The idea behind the console audio control is that the human operator
is the only one that can interact with it. The ThinkVantage suite in
Windows does not allow any software-based overrides, and only does OSD
(on-screen-display) functions.
The Linux driver will, with the addition of the ALSA interface, try to
follow and enforce the ThinkVantage UI design:
The user is supposed to use the keyboard hotkeys to interact with the
console audio control. The kernel and the desktop environment is
supposed to cooperate to provide proper user feedback through
on-screen-display functions.
Distros are urged to not to enable volume control by default.
Enabling this must be a local admin's decision. This is the reason
why there is no Kconfig option.
Keep in mind that all ThinkPads have a normal, main mixer (AC97 or
HDA) for regular software-based audio control. We are not talking
about that mixer here.
Advanced users are, of course, free to enable volume control and do as
they please.

Lenovo removed the extra mixer since the T61 and thereabouts.
Newer Lenovo models only have the mute gate function, and leave
the volume control to the HDA mixer.
Until a way to automatically query the firmware about its audio
control capabilities is discovered (there might not be any), use a
white/black list.
We will likely need to ask T60 (old and new model) and Z60/Z61 users
whether they have volume control to populate the black/white list.
Meanwhile, provide a volume_capabilities parameter that can be used to
override the defaults.

I don't trust the coupled EC writes and SMI calls the current volume
control code does very much, although it is exactly what the IBM DSDTs
seem to do (they never do more than a single step though).
Change the driver to stop issuing SMIs, and just drive the EC directly
to the desired level (DSDTs seem to confirm this will work even on
very old models like the 570 and 600e/x).
We checkpoint directly to NVRAM (this can be turned off) at
suspend/shutdown/driver unload, which from what I can see in tbp,
should also work on every ThinkPad.

Before we register the input device, sync the input layer EV_SW state
through a call to input_report_switch(), to avoid issuing a gratuitous
event for the initial state of these switches.
This fixes some annoyances caused by the interaction with rfkill and
EV_SW SW_RFKILL_ALL events.

It creates a regression, triggering badness for SYN_RECV
sockets, for example:
[19148.022102] Badness at net/ipv4/inet_connection_sock.c:293
[19148.022570] NIP: c02a0914 LR: c02a0904 CTR: 00000000
[19148.023035] REGS: eeecbd30 TRAP: 0700 Not tainted (2.6.32)
[19148.023496] MSR: 00029032 <EE,ME,CE,IR,DR> CR: 24002442 XER: 00000000
[19148.024012] TASK = eee9a820[1756] 'privoxy' THREAD: eeeca000
This is likely caused by the change in the 'estab' parameter
passed to tcp_parse_options() when invoked by the functions
in net/ipv4/tcp_minisocks.c
But even if that is fixed, the ->conn_request() changes made in
this patch series is fundamentally wrong. They try to use the
listening socket's 'dst' to probe the route settings. The
listening socket doesn't even have a route, and you can't
get the right route (the child request one) until much later
after we setup all of the state, and it must be done by hand.
This stuff really isn't ready, so the best thing to do is a
full revert. This reverts the following commits:

Ever since jffs2_garbage_collect_metadata() was first half-written in
February 2001, it's been broken on architectures where 'char' is signed.
When garbage collecting a symlink with target length above 127, the payload
length would end up negative, causing interesting and bad things to happen.
