Write-combine and cacheable mappings use Normal memory on arm64. On SMP
systems, the pte needs the shareability bit which is set in
pgprot_default. Use this for defining PROT_DEFAULT used by ioremap_wc
and ioremap_cache (Device memory is shareable by default, does not need
additional attributes).

The refactoring of el2_setup split code setting up EL2 and detecting the
CPU boot mode in separate chunks. This allows the code that sets up EL2 to
run in an endian independent way - ie before the endianess is set up in
the respective sctlr registers.
This patch brings secondary_entry up-to-date so that CPUs entering the
kernel through this code path set-up EL2 and the cpu boot mode properly.

Currently there is no dsb between the tlbi in __cpu_setup and the write
to SCTLR_EL1 which enables the MMU in __turn_mmu_on. This means that the
TLB invalidation is not guaranteed to have completed at the point
address translation is enabled, leading to a number of possible issues
including incorrect translations and TLB conflict faults.
This patch moves the tlbi in __cpu_setup above an existing dsb used to
synchronise I-cache invalidation, ensuring that the TLBs have been
invalidated at the point the MMU is enabled.

When creating IO mappings, we lazily allocate our page tables using the
standard, non-atomic allocator functions. This presents us with a
problem, since our page tables are protected with a spinlock.
This patch reworks the smmu_domain lock to use a mutex instead of a
spinlock. iova_to_phys is then reworked so that it only reads the page
tables, and can run in a lockless fashion, leaving the mutex to guard
against concurrent mapping threads.

Pull tracing fix from Steven Rostedt:
"A regression showed up that there's a large delay when enabling all
events. This was prevalent when FTRACE_SELFTEST was enabled which
enables all events several times, and caused the system bootup to
pause for over a minute.
This was tracked down to an addition of a synchronize_sched()
performed when system call tracepoints are unregistered.
The synchronize_sched() is needed between the unregistering of the
system call tracepoint and a deletion of a tracing instance buffer.
But placing the synchronize_sched() in the unreg of *every* system
call tracepoint is a bit overboard. A single synchronize_sched()
before the deletion of the instance is sufficient"

kill memcg_tcp_enter_memory_pressure. The only function of
memcg_tcp_enter_memory_pressure was to reduce deal with the
unnecessary abstraction that was tcp_memcontrol. Now that struct
tcp_memcontrol is gone remove this unnecessary function, the
unnecessary function pointer, and modify sk_enter_memory_pressure to
set this field directly, just as sk_leave_memory_pressure cleas this
field directly.
This fixes a small bug I intruduced when killing struct tcp_memcontrol
that caused memcg_tcp_enter_memory_pressure to never be called and
thus failed to ever set cg_proto->memory_pressure.
Remove the cg_proto enter_memory_pressure function as it now serves
no useful purpose.
Don't test cg_proto->memory_presser in sk_leave_memory_pressure before
clearing it. The test was originally there to ensure that the pointer
was non-NULL. Now that cg_proto is not a pointer the pointer does not
matter.

When booted with device tree, we may still have platform data passed
as auxdata. For am3517 this is needed for passing the interrupt_enable
and interrupt_disable callbacks that access the omap system control module
registers. These callback functions will eventually go away when we have
a separate system control module driver.
Some of the things that are currently passed as platform data we don't need
to set up as device tree properties as they are always the same on am3517.
So let's use a new compatible flag for those so we can get those from
the device tree match data.
Also note that we need to fix setting of phy_dev to NULL instead of an empty
string as the code later on uses that to find the first phy on the mdio bus.

"I have here a few fixes for BT Coex. One of them is a NULL pointer
dereference. Another one avoids to enable a feature that can make the
firmware unhappy since the firmware isn't ready for it yet. WE also
avoid a WARNING that can be triggered upon association in not-so-bad
cases even if the association succeeded. We add support for new NICs
(not yet on the market) and bump the API so that 3.13 will be able to
work with the new firmware that will be out soon hopefully.
I also have a boundary check from Johannes."

It has been reported that boot up with FTRACE_SELFTEST enabled can take a
very long time. There can be stalls of over a minute.
This was tracked down to the synchronize_sched() called when a system call
event is disabled. As the self tests enable and disable thousands of events,
this makes the synchronize_sched() get called thousands of times.
The synchornize_sched() was added with d562aff93b "tracing: Add support
for SOFT_DISABLE to syscall events" which caused this regression (added
in 3.13-rc1).
The synchronize_sched() is to protect against the events being accessed
when a tracer instance is being deleted. When an instance is being deleted
all the events associated to it are unregistered. The synchronize_sched()
makes sure that no more users are running when it finishes.
Instead of calling synchronize_sched() for all syscall events, we only
need to call it once, after the events are unregistered and before the
instance is deleted. The event_mutex is held during this action to
prevent new users from enabling events.
