Sicne the platform data's buffer_size now holds the full size
of the FIFO, there is no longer need to handle the ports
differently.

Use the actual FIFO size in words as buffer_size on OMAP3.
Change the threshold configuration to use 1 based numbering, when
specifying the allowed threshold maximum or the McBSP threshold value.
Set the default maximum threshold to (buffer_size - 0x10) intialy.
>From users of McBSP, now it is expected to use this method.
Asking for threshold 1 means that the value written to threshold registers
are going to be 0, which means 1 word threshold.

Users of McBSP can use the omap_mcbsp_get_fifo_size function to query
the size of the McBSP FIFO.
The function will return the FIFO size in words (the HW maximum).

Machine driver can instruct the codec driver to reset the
chip registers to their default values at probe time.
If machine driver does not provide setup data, then the
registers are going to be reseted to their defaults, to
be safe.
If the developer on the platform confirms that the register
reset is not needed, than it can be skipped, saving ~20ms
time in probe.
As safety measure do the register reset at remove time also.

Since the reg cache now contains the chip default values
for all registers (REG_OPTION is reset to it's default
within this patch), there is no longer need to rewrite
_all_ registers.
Initialize only few selected registers.
According to the latest information, the offset cancellation
need to be done only once, when the codec is powered on, so
there is no need for the power up wrapper.
Move all chip initialization code under chip_init, and do
it when the codec is initialized.

This patch is meant to improve the performance of SLUB by moving the local
kmem_cache_node lock into it's own cacheline separate from kmem_cache.
This is accomplished by simply removing the local_node when NUMA is enabled.
On my system with 2 nodes I saw around a 5% performance increase w/
hackbench times dropping from 6.2 seconds to 5.9 seconds on average. I
suspect the performance gain would increase as the number of nodes
increases, but I do not have the data to currently back that up.

mutex: Fix optimistic spinning vs. BKL

Currently, we can hit a nasty case with optimistic
spinning on mutexes:
CPU A tries to take a mutex, while holding the BKL
CPU B tried to take the BLK while holding the mutex
This looks like a AB-BA scenario but in practice, is
allowed and happens due to the auto-release on
schedule() nature of the BKL.
In that case, the optimistic spinning code can get us
into a situation where instead of going to sleep, A
will spin waiting for B who is spinning waiting for
A, and the only way out of that loop is the
need_resched() test in mutex_spin_on_owner().
This patch fixes it by completely disabling spinning
if we own the BKL. This adds one more detail to the
extensive list of reasons why it's a bad idea for
kernel code to be holding the BKL.

Currently the trace splice code zeros out the excess bytes in the page before
sending it off to userspace.
This is to make sure userspace is not getting anything it should not be
when reading the pages, because the excess data was never initialized
to zero before writing (for perfomance reasons).
But the splice code has no business in doing this work, it should be
done by the ring buffer. With the latest changes for recording lost
events, the splice code gets it wrong anyway.
Move the zeroing out of excess bytes into the ring buffer code.

The code to store the "lost events" requires knowing the real end
of the page. Since the 'commit' includes the padding at the end of
a page a "real_end" variable was used to keep track of the end not
including the padding.
If events were lost, the reader can place the count of events in
the padded area if there is enough room.
The bug this patch fixes is that when we fill the page we do not
reset the real_end variable, and if the writer had wrapped a few
times, the real_end would be incorrect.
This patch simply resets the real_end if the page was filled.

When we moved to using ~/.perfconfig to set the value of use_browser,
it changed from a boolean to an int so that the convention used for
use_pager was followed.
That convention is:
-1: unspecified, that is what use_{browser,pager} is initialized
0: Don't use the browser (should be TUI), because was explicitely
set to 0/off/false on ~/.perfconfig [tui] cmd =, or because
we're redirecting the stdout to a file or piping it to some
other command (!isatty()).
1: Use the TUI
Some code was not properly audited and continued testing it as a
boolean, this seems to be the last one.

So that if the kernel DSO has a build id because record inserted it in
the perf.data build id table in the header, or a BUILD_ID event was
inserted in the stream, we first look at the build id cache
($HOME/.debug/).
If we find it there, try to use it, allowing offline annotation in
addition to 'perf report'.

The newt initialization routines weren't being called because the output
was a file (perf annotate > /tmp/bla) but use_browser was still 1,
because ~/.perfconfig had it as 'on', so, later on newt routines
segfaulted.

This partially reverts commit 4ec37de89d8c758ee8115e0e64b3f994910789ee
("[IA64] Fix build breakage"), since the commit that made it necessary
got reverted earlier (see commit 35926ff5fba8, 'Revert "cpusets:
randomize node rotor used in cpuset_mem_spread_node()"')
Even if we ever re-introduce this, there is no reason to make
__node_random be some architecture-specific function.

This is needed by fuse device code which wants to create pipe buffers.

Allow userspace filesystem implementation to use splice() to read from
the fuse device.
The userspace filesystem can now transfer data coming from a WRITE
request to an arbitrary file descriptor (regular file, block device or
socket) without having to go through a userspace buffer.
The semantics of using splice() to read messages are:
1) with a single splice() call move the whole message from the fuse
device to a temporary pipe
2) read the header from the pipe and determine the message type
3a) if message is a WRITE then splice data from pipe to destination
3b) else read rest of message to userspace buffer
