Ocfs2 uses kiocb.*private as a flag of unsigned long size. In
commit a11f7e63 ocfs2: serialize unaligned aio, the unaligned
io flag is involved in it to serialize the unaligned aio. As
*private is not initialized in init_sync_kiocb() of do_sync_write(),
this unaligned io flag may be unexpectly set in an aligned dio.
And this will cause OCFS2_I(inode)->ip_unaligned_aio decreased
to -1 in ocfs2_dio_end_io(), thus the following unaligned dio
will hang forever at ocfs2_aiodio_wait() in ocfs2_file_aio_write().

Since commit 1c6c6952 ("genirq: Reject bogus threaded irq requests")
threaded IRQs without a primary handler need to be requested with
IRQF_ONESHOT, otherwise the request will fail. This patch adds the
IRQF_ONESHOT to input drivers where it is missing. Not modified by
this patch are those drivers where the requested IRQ will always be a
nested IRQ (e.g. because it's part of an MFD), since for this special
case IRQF_ONESHOT is not required to be specified when requesting the
IRQ.

The OMAP4 usb_host_fs (OHCI) and AESS IP blocks require some special
programming for them to enter idle.  Without this programming, they
will prevent the rest of the chip from entering full chip idle.

To implement the idle programming cleanly, this will take some
coordination between maintainers.  This is likely to take some time,
so it is probably best to leave this for 3.6 or 3.7.  So, in the
meantime, prevent these IP blocks from being registered.

Later, once the appropriate support is available, this patch can be
reverted.

This second version comments out the IP block data since Benoît didn't
like removing it.

'status' variable in ocfs2_global_read_info() is always != 0 when leaving the
function because it happens to contain number of read bytes. Thus we always log
error message although everything is OK. Since all error cases properly call
mlog_errno() before jumping to out_err, there's no reason to call mlog_errno()
on exit at all. This is a fallout of c1e8d35e (conversion of mlog_exit()
calls).

Hello,

Since ENXIO only means "offset beyond EOF" for SEEK_DATA/SEEK_HOLE,
Hence we should return the internal error unchanged if ocfs2_inode_lock() or
ocfs2_get_clusters_nocache() call failed rather than ENXIO.
Otherwise, it will confuse the user applications when they trying to understand the root cause.

In commit 070ad7e7 ("floppy: convert to delayed work and
single-thread wq") the 'fd_timeout' timer was converted to a delayed
work.  However, the "del_timer(&fd_timeout)" was lost in the process,
and any previous pending timeouts would stay active when we then
re-queued the timeout.

This resulted in the floppy probe sequence having a (stale) 20s timeout
rather than the intended 3s timeout, and thus made booting with the
floppy driver (but no actual floppy controller) take much longer than it
should.

Of course, there's little reason for most people to compile the floppy
driver into the kernel at all, which is why most people never noticed.

Canceling the delayed work where we used to do the del_timer() fixes the
issue, and makes the floppy probing use the proper new timeout instead.
The three second timeout is still very wasteful, but better than the 20s
one.

This is caused by shrinking page from the empty mmu, although we have
checked n_used_mmu_pages, it is useless since the check is out of mmu-lock

The below commit introduced a bug in __clk_set_parent()
which could cause it to *skip* the parent validation
which makes sure the parent passed to the api is a valid
one.

    commit 7975059d
    Author: Rajendra Nayak <rnayak@ti.com>
    Date:   Wed Jun 6 14:41:31 2012 +0530

        clk: Allow late cache allocation for clk->parents

This was identified by the following compiler warning..

    drivers/clk/clk.c: In function '__clk_set_parent':
    drivers/clk/clk.c:1083:5: warning: 'i' may be used uninitialized in this function [-Wuninitialized]

.. as reported by Marc Kleine-Budde.

There were various options discussed on how to fix this, one
being initing 'i' to clk->num_parents, but the below approach
was found to be more appropriate as it also makes the 'parent
validation' code simpler to read.

  We originally were going to leave the i915 fix until -next, but grub2

  causes big slowdowns, and I have reports in rawhide I'd like to have
  fixed."

When the server doesn't advertise CAP_LARGE_READ_X, then MS-CIFS states
that you must cap the size of the read at the client's MaxBufferSize.
Unfortunately, testing with many older servers shows that they often
can't service a read larger than their own MaxBufferSize.

Since we can't assume what the server will do in this situation, we must
be conservative here for the default. When the server can't do large
reads, then assume that it can't satisfy any read larger than its
MaxBufferSize either.

Luckily almost all modern servers can do large reads, so this won't
affect them. This is really just for older win9x and OS/2 era servers.
Also, note that this patch just governs the default rsize. The admin can
always override this if he so chooses.
