This code will be eventually in drivers, and for the
code in the drivers we don't want to have any cpu_is_omap
usage. Those macros should be private to arch/arm/mach-omap1
and arch/arm/mach-omap2.
To fix this, let's move the define for dma_omap2plus()
to dma-omap.h, and use the existing dma_attr passed in
the platform_data as the revision registers are what they
are.
Note that we can now also remove the relative includes
introduced by the recent clean-up patches.

This code should be private to mach-omap2.
The only use for it in for omap1 has been in dmtimer.c
to check for context loss. However, omap1 does not
lose context during idle, so the code is not needed.
Further, omap1 timer has OMAP_TIMER_ALWON set, so omap1
was not hitting omap_pm_get_dev_context_loss_count()
test.

Modify divisor to select the nearest baud rate divider rather than the
lowest. It minimizes baud rate errors especially on low UART clock
frequencies.
For example, if uartclk is 33000000 and baud is 115200 the ratio is
about 17.9 The current code selects 17 (5% error) but should select 18
(0.5% error).
This 5% error in baud rate leads to garbage on receiving end, while 0.5%
doesn't.
The issue showed up when using the stock 8250 driver for
Synopsys DW UART. This was on a FPGA with ~12MHz UART clock.
When we enabled early serial, we saw garbage which was narrowed down
to the rounding error.
So the bug had been latent and it only showed up with such low clock rates.

When a driver has the low_latency flag set and uses the schedule_flip()
function to initiate copying data to the line discipline, a workqueue is
scheduled in but never actually flushed. This is incorrect use of the
low_latency flag (driver should not support the low_latency flag, or use
the tty_flip_buffer_push() function instead). Make sure a warning is
reported to catch incorrect use of the low_latency flag.

For that purpose we have to temporarily introduce a second tty back
pointer into tty_port. It is because serial layer, and maybe others,
still do not use tty_port_tty_set/get. So that we cannot set the
tty_port->tty to NULL at will now.
Yes, the fix would be to convert whole serial layer and all its users
to tty_port_tty_set/get. However we are in the process of removing the
need of tty in most of the call sites, so this would lead to a
duplicated work.
Instead we have now tty_port->itty (internal tty) which will be used
only in flush_to_ldisc. For that one it is ensured that itty is valid
wherever the work is run. IOW, the work is synchronously cancelled
before we set itty to NULL and also before hangup is processed.
After we need only tty_port and not tty_struct in most code, this
shall be changed to tty_port_tty_set/get and itty removed completely.

we have a valid tty. Second, as ld->ops->set_termios from
tty_set_termios. But there we have a valid tty too.
* if (!tty) in n_tty_open -- why would the TTY layer call ldisc's

a tty and dereference that.
* BUG_ON(!tty->read_buf) in n_tty_read -- this used to be a valid
check. The ldisc handling was broken some time ago when I added the
check to ensure everything is OK. It still can catch the case, but
no later than we move the buffer to ldisc data. Then there will be
no read_buf in tty_struct, i.e. nothing to check for.
* if (!tty->read_buf) in n_tty_receive_buf -- this should never
happen. All callers of ldisc->ops->receive_ops should hold a
reference to an ldisc and close (which frees read_buf) cannot be
called until the reference is dropped.

since ld->ops->open shall be called only once, we do not need the

We reintroduced tty_ldisc_wait_idle in 100eeae2c5 (TTY: restore
tty_ldisc_wait_idle) and used in set_ldisc. Then we added it also to
the hangup path in 92f6fa09bd (TTY: ldisc, do not close until there
are readers). And we noted that there is one more path:
~ Before 65b770468e tty_ldisc_wait_idle was called also from
~ tty_ldisc_release. It is called from tty_release, so I don't think
~ we need to restore that one.
Well, I was wrong. There might still be holders of an ldisc
reference. Not from userspace, but drivers. If they take a reference
and a user closes the device immediately after that, we have a
problem. ldisc is halted and closed by TTY, but the driver still may
call some ldisc's operation and cause a crash.
So restore the tty_ldisc_wait_idle call also to the third location
where it was before 65b770468e (tty-ldisc: turn ldisc user count
into a proper refcount). Now we should be safe with respect to the
ldisc reference counting as all* tty_ldisc_close paths are safely
called with reference count of one.
* Not the one in tty_ldisc_setup's fail path. But that is called
before the first open finishes. So userspace does not see it yet.
Even thought the driver is given the TTY already via ->install, it
should not take a reference to the ldisc yet. If some driver is to
do this, we should put one tty_ldisc_wait_idle also in the setup.

There used to be a single tty_ldisc_ref_wait. But then, when a
big-tty-mutex (BTM) was introduced, it has to be tty_ldisc_ref +
tty_unlock + tty_ldisc_ref_wait + tty_lock. Later, BTM was removed
from that path and tty_ldisc_ref + tty_ldisc_ref_wait remained there.
But it makes no sense now. So leave there only tty_ldisc_ref_wait.
And when we have a reference to an ldisc, actually use it in the loop.
Otherwise it may be racy.

When low_latency flag is set the TTY receive flip buffer is copied to the
line discipline directly instead of using a work queue in the background.
Therefor only in case a workqueue is actually used for copying data to the
line discipline we'll have to flush the workqueue.
This prevents unnecessary spin lock/unlock on the workqueue spin lock that
can cause additional scheduling overhead on a PREEMPT_RT system. On a 200
MHz AT91SAM9261 processor setup this fixes about 100us of scheduling

Commit cb6b6df111 ("xen/pv-on-hvm kexec: add quirk for Xen 3.4 and
shutdown watches.") added the xen_strict_xenbus_quirk() function with an
old K&R-style declaration without proper typing, causing gcc to rightly
complain:
drivers/xen/xenbus/xenbus_xs.c:628:13: warning: function declaration isn’t a prototype [-Wstrict-prototypes]
because we really don't live in caves using stone-age tools any more,
and the kernel has always used properly typed ANSI C function
declarations.
So if a function doesn't take arguments, we tell the compiler so
explicitly by adding the proper "void" in the prototype.
I'm sure there are tons of other examples of this kind of stuff in the
tree, but this is the one that hits my workstation config, so..

Here are the USB patches against your 3.7-rc1 tree.
There are the usual UABI header file movements, and we finally are now
able to remove the dbg() macro that is over 15 years old (that had to
wait for after some other trees got merged into yours during the big
3.7-rc1 merge window.)
Other than that, nothing major, just a number of bugfixes and new device
ids. It turns out that almost all of the usb-serial drivers had bugs in
how they were handling their internal data, leaking memory, hence all of
those fixups.

Pull media fixes from Mauro Carvalho Chehab:
"Media fixes for:
- one Kconfig fix patch;
- one patch fixing DocBook breakage due to the drivers/media UAPI
changes;
- the remaining UAPI media changes (DVB API).
I'm aware that is is a little late for the UAPI renames for the DVB
API, but IMHO, it is better to merge it for 3.7, due to two reasons:
1) There is a major rename at 3.7 (not only uapi changes, but also
the entire media drivers were reorganized on 3.7, in order to
simplify the Kconfig logic, and easy drivers selection, especially
for hybrid devices). By confining all those renames there at 3.7
it will cause all the harm at for media developers on just one
shot. Stable backports upstream and at distros will likely
welcome it as well, as they won't need to check what changed on
3.7 and what was postponed for on 3.8.
2) The V4L2 DocBook Makefile creates a cross-reference between the
media API headers and the specs. This helps us _a_lot_ to be sure
that all API improvements are properly documented. Every time a
header changes from one place to another, DocBook/media/Makefile
needs to be patched. Currently, the DocBook breakage patch
depends on the DVB UAPI."

Here's the first set of fixes for v3.7-rc cycle.
DesignWare Core USB3 Driver (dwc3) got two fixes. The first one fixes a long
standing bug which would keep endpoint with BUSY flag set forever if we cancel
a transfer which has already been started by the controller. The second fix
will just switch PHYs back off when DWC3 driver is removed.
MUSB fixed a bug which would cause a Kernel Oops at least on AM3517 when
removing a device. For some reason that particular device can fall into a
situation where you have both Disconnect and Endpoint IRQs happen
simultaneously (have both bits set in IRQ_STATUS register) and, because
Disconnect Interrupt is handled before Endpoint Interrupts, we would try to
transfer data over a disconnected device, thus generating a kernel oops.
Renensas' USB DRD driver got two fixes which are a) fixing an off-by-one bug on
the pipe iterator implementation and b) fixing Interrupt Status Clear procedure
in order to properly clear a single Interrupt event without clearing (and
masking) other events we didn't handle yet.
