sh: Don't allocate smaller sized mappings on every iteration
Currently, we've got the less than ideal situation where if we need to
allocate a 256MB mapping we'll allocate four entries like so,
entry 1: 128MB
entry 2: 64MB
entry 3: 16MB
entry 4: 16MB
This is because as we execute the loop in pmb_remap() we will
progressively try mapping the remaining address space with smaller and
smaller sizes. This isn't good because the size we use on one iteration
may be the perfect size to use on the next iteration, for instance when
the initial size is divisible by one of the PMB mapping sizes.
With this patch, we now only need two entries in the PMB to map 256MB of
address space,
entry 1: 128MB
entry 2: 128MB

fix readahead calculations in xfs_dir2_leaf_getdents()
This is for bug #850,
http://oss.sgi.com/bugzilla/show_bug.cgi?id=850
XFS file system segfaults , repeatedly and 100% reproducable in 2.6.30 , 2.6.31
The above only showed up on a CONFIG_XFS_DEBUG=y kernel, because
xfs_bmapi() ASSERTs that it has been asked for at least one map,
and it was getting 0.
The root cause is that our guesstimated "bufsize" from xfs_file_readdir
was fairly small, and the
bufsize -= length;
in the loop was going negative - except bufsize is a size_t, so it
was wrapping to a very large number.
Then when we did
ra_want = howmany(bufsize + mp->m_dirblksize,
mp->m_sb.sb_blocksize) - 1;
with that very large number, the (int) ra_want was coming out
negative, and a subsequent compare:
if (1 + ra_want > map_blocks ...
was coming out -true- (negative int compare w/ uint) and we went
back to xfs_bmapi() for more, even though we did not need more,
and asked for 0 maps, and hit the ASSERT.
We have kind of a type mess here, but just keeping bufsize from
going negative is probably sufficient to avoid the problem.

We want to always cover the log after writing out the superblock, and

xfs: implement ->dirty_inode to fix timestamp handling
This is picking up on Felix's repost of Dave's patch to implement a
.dirty_inode method. We really need this notification because
the VFS keeps writing directly into the inode structure instead
of going through methods to update this state. In addition to
the long-known atime issue we now also have a caller in VM code
that updates c/mtime that way for shared writeable mmaps. And
I found another one that no one has noticed in practice in the FIFO
code.
So implement ->dirty_inode to set i_update_core whenever the
inode gets externally dirtied, and switch the c/mtime handling to
the same scheme we already use for atime (always picking up
the value from the Linux inode).
Note that this patch also removes the xfs_synchronize_atime call
in xfs_reclaim it was superflous as we already synchronize the time
when writing the inode via the log (xfs_inode_item_format) or the
normal buffers (xfs_iflush_int).
In addition also remove the I_CLEAR check before copying the Linux
timestamps - now that we always have the Linux inode available
we can always use the timestamps in it.
Also switch to just using file_update_time for regular reads/writes -
that will get us all optimization done to it for free and make
sure we notice early when it breaks.

x86, timers: Check for pending timers after (device) interrupts
Now that range timers and deferred timers are common, I found a
problem with these using the "perf timechart" tool. Frans Pop also
reported high scheduler latencies via LatencyTop, when using
iwlagn.
It turns out that on x86, these two 'opportunistic' timers only get
checked when another "real" timer happens. These opportunistic
timers have the objective to save power by hitchhiking on other
wakeups, as to avoid CPU wakeups by themselves as much as possible.
The change in this patch runs this check not only at timer
interrupts, but at all (device) interrupts. The effect is that:
1) the deferred timers/range timers get delayed less
2) the range timers cause less wakeups by themselves because
the percentage of hitchhiking on existing wakeup events goes up.
I've verified the working of the patch using "perf timechart", the
original exposed bug is gone with this patch. Frans also reported
success - the latencies are now down in the expected ~10 msec
range.

mm, perf_event: Make vmalloc_user() align base kernel virtual address to SHMLBA
When a vmalloc'd area is mmap'd into userspace, some kind of
co-ordination is necessary for this to work on platforms with cpu
D-caches which can have aliases.
Otherwise kernel side writes won't be seen properly in userspace
and vice versa.
If the kernel side mapping and the user side one have the same
alignment, modulo SHMLBA, this can work as long as VM_SHARED is
shared of VMA and for all current users this is true. VM_SHARED
will force SHMLBA alignment of the user side mmap on platforms with
D-cache aliasing matters.
The bulk of this patch is just making it so that a specific
alignment can be passed down into __get_vm_area_node(). All
existing callers pass in '1' which preserves existing behavior.
vmalloc_user() gives SHMLBA for the alignment.
As a side effect this should get the video media drivers and other
vmalloc_user() users into more working shape on such systems.

ALSA: ICE1712/24 - Change the Multi Track Peak control (level meters) from MIXER to PCM type
* PLEASE NOTE - this change requires the corresponding update of
envy24control for ice1712 - kind of an ABI change.
* The "Multi Track Peak" control is read-only level meters indicator.
* The control is VERY confusing to most users since it is currently displayed
in regular mixers. E.g. alsamixer ignores its read-only status
and allows changing the levels with keys which makes no sense.

Blackfin: fix framebuffer mmap bug for nommu
The patch added a special get_unmapped_area for framebuffer which
was hooked to the file ops in drivers/video/fbmem.c.
This is needed since v2.6.29-rc1 where nommu vma management was
updated, and mmap of framebuffer caused kernel BUG panic. You may turn
on "Debug the global anon/private NOMMU mapping region tree" config to
such message.
As Documentation/nommu-mmap.txt said,
"To provide shareable character device support, a driver must provide
a file->f_op->get_unmapped_area() operation. The mmap() routines will
call this to get a proposed address for the mapping."
With this change, user space should call mmap for framebuffer using
shared map. Or it can try shared map first, then private map if
failed. This shared map usage is now consistent between mmu and nommu.
The sys_ file may not be a good place for this patch. But there is a
similar one for sparc. I tested a similar patch on nios2nommu, though
I don't have a blackfin board to test.
