ff4569c752 [MTD] [NAND] davinci_nand driver
This is a device driver for the NAND flash controller found on the various
DaVinci family chips.  It handles up to four SoC chipselects, and some
flavors of secondary chipselect (e.g.  based on upper bits of the address
bus) as used with some multichip packages.  (Including the 2 GiB chips
used on some TI devel boards.)

The 1-bit ECC hardware is supported (3 bytes ECC per 512 bytes data); but
not yet the newer 4-bit ECC (10 bytes ECC per 512 bytes data), as
available on chips like the DM355 or OMAP-L137 and needed with the more
error-prone MLC NAND chips.

This is a cleaned-up version of code that's been in use for several years
now; sanity checked with the new drivers/mtd/tests.

52ff49df7f [MTD] [NAND] fix "raw" reads with ECC syndrome layouts
The syndrome based page read/write routines store ECC, and possibly other
"OOB" data, right after each chunk of ECC'd data.  With ECC chunk size of
512 bytes and a large page (2KiB) NAND, the layout is:

  data-0 OOB-0 data-1 OOB-1 data-2 OOB-2 data-3 OOB-3 OOB-leftover

Where OOBx is (prepad, ECC, postpad).  However, the current "raw" routines
use a traditional layout -- data OOB, disregarding the prepad and postpad
values -- so when they're used with that type of ECC hardware, those calls
mix up the data and OOB.  Which means, in particular, that bad block
tables won't be found on startup, with data corruption and related chaos
ensuing.

The current syndrome-based drivers in mainline all seem to use one chunk
per page; presumably they haven't noticed such bugs.

Fix this, by adding read/write page_raw_syndrome() routines as siblings of
the existing non-raw routines; "raw" just means to bypass the ECC
computations, not change data and OOB layout.

65c24491b4 aio: lookup_ioctx can return the wrong value when looking up a bogus context
The libaio test harness turned up a problem whereby lookup_ioctx on a
bogus io context was returning the 1 valid io context from the list
(harness/cases/3.p).

Because of that, an extra put_iocontext was done, and when the process
exited, it hit a BUG_ON in the put_iocontext macro called from exit_aio
(since we expect a users count of 1 and instead get 0).

The problem was introduced by "aio: make the lookup_ioctx() lockless"
(commit abf137dd77).

Thanks to Zach for pointing out that hlist_for_each_entry_rcu will not
return with a NULL tpos at the end of the loop, even if the entry was
not found.

87c3a86e1c eventfd: remove fput() call from possible IRQ context
Remove a source of fput() call from inside IRQ context.  Myself, like Eric,
wasn't able to reproduce an fput() call from IRQ context, but Jeff said he was
able to, with the attached test program.  Independently from this, the bug is
conceptually there, so we might be better off fixing it.  This patch adds an
optimization similar to the one we already do on ->ki_filp, on ->ki_eventfd.
Playing with ->f_count directly is not pretty in general, but the alternative
here would be to add a brand new delayed fput() infrastructure, that I'm not
sure is worth it.

a8e7d49aa7 Fix race in create_empty_buffers() vs __set_page_dirty_buffers()
Nick Piggin noticed this (very unlikely) race between setting a page
dirty and creating the buffers for it - we need to hold the mapping
private_lock until we've set the page dirty bit in order to make sure
that create_empty_buffers() might not build up a set of buffers without
the dirty bits set when the page is dirty.

I doubt anybody has ever hit this race (and it didn't solve the issue
Nick was looking at), but as Nick says: "Still, it does appear to solve
a real race, which we should close."

68df3755e3 Add '-fwrapv' to gcc CFLAGS
This makes sure that gcc doesn't try to optimize away wrapping
arithmetic, which the kernel occasionally uses for overflow testing, ie
things like

	if (ptr + offset < ptr)

which technically is undefined for non-unsigned types. See

	http://bugzilla.kernel.org/show_bug.cgi?id=12597

for details.

Not all versions of gcc support it, so we need to make it conditional
(it looks like it was introduced in gcc-3.4).

0fb1d9bcbc [S390] make page table upgrade work again
After TASK_SIZE now gives the current size of the address space the
upgrade of a 64 bit process from 3 to 4 levels of page table  needs
to use the arch_mmap_check hook to catch large mmap lengths. The
get_unmapped_area* functions need to check for -ENOMEM from the
arch_get_unmapped_area*, upgrade the page table and retry.

f481bfafd3 [S390] make page table walking more robust
Make page table walking on s390 more robust. The current code requires
that the pgd/pud/pmd/pte loop is only done for address ranges that are
below the end address of the last vma of the address space. But this
is not always true, e.g. the generic page table walker does not guarantee
this. Change TASK_SIZE/TASK_SIZE_OF to reflect the current size of the
address space. This makes the generic page table walker happy but it
breaks the upgrade of a 3 level page table to a 4 level page table.
To make the upgrade work again another fix is required.

2887fc5aa6 [S390] Dont check for pfn_valid() in uaccess_pt.c
pfn_valid() actually checks for a valid struct page and not for a
valid pfn. Using xip mappings w/o struct pages, this will result in
-EFAULT returned by the (page table walk) user copy functions,
even though there is valid memory. Those user copy functions don't
need a struct page, so this patch just removes the pfn_valid() check.

* newer versions of the Novatel Wireless U727 CDMA 3G USB stick
   have a different Product ID (0x5010); adding this ID makes them
   work just fine with the option driver

0cc6bfe901 USB: Option: let cdc-acm handle Sony Ericsson F3507g / Dell 5530
The generic cdc-acm driver is now the best one to handle Sony Ericsson
F3507g-based devices (which the Dell 5530 is a rebrand of), now that all
the pieces are in place (ie, cac477e8f1).
Removing the IDs from option allows cdc-acm to handle the device.

391016f6e2 USB: EHCI: expedite unlinks when the root hub is suspended
This patch (as1225) fixes a bug in ehci-hcd.  The condition for
whether unlinked QHs can become IDLE should not be that the controller
is halted, but rather that the controller isn't running.  In other
words when the root hub is suspended, the hardware doesn't own any
QHs.

This fixes a problem that can show up during hibernation: If a QH is
only partially unlinked when the root hub is frozen, then when the
root hub is thawed the QH won't be in the IDLE state.  As a result it
can't be used properly for new URB submissions.

508db8c954 USB: EHCI: Fix isochronous URB leak
ehci-hcd uses usb_get_urb() and usb_put_urb() in an unbalanced way causing
isochronous URB's kref.counts incrementing once per usb_submit_urb() call.
The culprit is *usb being set to NULL when usb_put_urb() is called after URB
is given back.
Due to other fixes there is no need for ehci-hcd to deal with usb_get_urb()
nor usb_put_urb() anymore, so patch removes their usages in ehci-hcd.
Patch also makes ehci_to_hcd(ehci)->self.bandwidth_allocated adjust, if a
stream finishes.
