Pull Xen updates from Konrad Rzeszutek Wilk:
"This has tons of fixes and two major features which are concentrated
around the Xen SWIOTLB library.
The short <blurb> is that the tracing facility (just one function) has
been added to SWIOTLB to make it easier to track I/O progress.
Additionally under Xen and ARM (32 & 64) the Xen-SWIOTLB driver
"is used to translate physical to machine and machine to physical
addresses of foreign[guest] pages for DMA operations" (Stefano) when
booting under hardware without proper IOMMU.
There are also bug-fixes, cleanups, compile warning fixes, etc.
The commit times for some of the commits is a bit fresh - that is b/c
we wanted to make sure we have the Ack's from the ARM folks - which
with the string of back-to-back conferences took a bit of time. Rest
assured - the code has been stewing in #linux-next for some time.

- SWIOTLB has tracing added when doing bounce buffer.

ERROR: "__divdi3" [fs/hfsplus/hfsplus.ko] undefined!
Introduced by commit 099e9245e0 ("hfsplus: implement attributes file's
header node initialization code").
i_size_read() returns loff_t, which is long long, i.e. 64-bit. node_size
is size_t, which is either 32-bit or 64-bit. Hence
"i_size_read(attr_file) / node_size" is a 64-by-32 or 64-by-64 division,
causing (some versions of) gcc to emit a call to __divdi3().
Fortunately node_size is actually 16-bit, as the sole caller of
hfsplus_init_header_node() passes a u16. Hence change its type from
size_t to u16, and use do_div() to perform a 64-by-32 division.
Not seen in m68k/allmodconfig in -next, so it really depends on the
verion of gcc.

This patch enhances the type safety for the kfifo API. It is now safe
to put const data into a non const FIFO and the API will now generate a
compiler warning when reading from the fifo where the destination
address is pointing to a const variable.
As a side effect the kfifo_put() does now expect the value of an element
instead a pointer to the element. This was suggested Russell King. It
make the handling of the kfifo_put easier since there is no need to
create a helper variable for getting the address of a pointer or to pass
integers of different sizes.
IMHO the API break is okay, since there are currently only six users of
kfifo_put().
The code is also cleaner by kicking out the "if (0)" expressions.

For the casual device driver writer, it is hard to remember when to use
init_completion (to init a completion structure) or INIT_COMPLETION (to
*reinit* a completion structure). Furthermore, while all other
completion functions exepct a pointer as a parameter, INIT_COMPLETION
does not. To make it easier to remember which function to use and to
make code more readable, introduce a new inline function with the proper
name and consistent argument type. Update the kernel-doc for
init_completion while we are here.

This ignores %n in printf again, as was originally documented.
Implementing %n poses a greater security risk than utility, so it should
stay ignored. To help anyone attempting to use %n, a warning will be
emitted if it is encountered.
Based on an earlier patch by Joe Perches.
Because %n was designed to write to pointers on the stack, it has been
frequently used as an attack vector when bugs are found that leak
user-controlled strings into functions that ultimately process format
strings. While this class of bug can still be turned into an
information leak, removing %n eliminates the common method of elevating
such a bug into an arbitrary kernel memory writing primitive,
significantly reducing the danger of this class of bug.
For seq_file users that need to know the length of a written string for
padding, please see seq_setwidth() and seq_pad() instead.

If split page table lock is in use, we embed the lock into struct page
of table's page. We have to disable split lock, if spinlock_t is too

enabled.
This patch add support for dynamic allocation of split page table lock
if we can't embed it to struct page.
page->ptl is unsigned long now and we use it as spinlock_t if
sizeof(spinlock_t) <= sizeof(long), otherwise it's pointer to spinlock_t.
The spinlock_t allocated in pgtable_page_ctor() for PTE table and in
