Some SoC need to redefine MSM_DGT_BASE from it's default.
This allows it to be defined in a header to override the
default value.

By default, event inheritance across fork and pthread_create was on but the -i
option of stat and record, which enabled inheritance, led to believe it was off
by default.
This patch fixes this logic by inverting the meaning of the -i option. By
default inheritance is on whether you attach to a process (-p), a thread (-t)
or start a process. If you pass -i, then you turn off inheritance. Turning off
inheritance if you don't need it, helps limit perf resource usage as well.
The patch also fixes perf stat -t xxxx and perf record -t xxxx which did not
start the counters.

The imx CTS trigger level is left at its reset value that is 32
chars. Since the RX FIFO has 32 entries, when CTS is raised, the
FIFO already is full. However, some serial port devices first empty
their TX FIFO before stopping when CTS is raised, resulting in lost
chars.
This patch sets the trigger level lower so that other chars arrive
after CTS is raised, there is still room for 16 of them.

In CONFIG_PTE_64BIT the PTE format has unique permission bits for user
and supervisor execute. However on !CONFIG_PTE_64BIT we overload the
supervisor bit to imply user execute with _PAGE_USER set. This allows
us to use the same permission check mask for user or supervisor code on
!CONFIG_PTE_64BIT.
However, on CONFIG_PTE_64BIT we map _PAGE_EXEC to _PAGE_BAP_UX so we
need a different permission mask based on the fault coming from a kernel
address or user space.
Without unique permission masks we see issues like the following with
modules:
Unable to handle kernel paging request for instruction fetch

The short preamble setting might change on the
fly, and then we already use the right mac80211
variable. However, in other places we don't,
which is especially wrong in the AP code since
in that case the assoc_capability is invalid.
Also, the IBSS special case is not needed since
"use_short_slot" will be properly cleared, but
the "assoc_capability" might be invalid (which
must be the reason for the special case).

There are a few places where sta_lock is used, but the
station information protected by it is accessed outside
of the lock. Address this in two ways, if the access
won't sleep then just move the access into the lock, if
the access can sleep then copy the needed station
information to the stack to be accessed without risk of
it changing while access in progress.
Additionally, a number of other places access station
station information without holding the sta_lock, fix
those as well.

This patch allows for a more flexible ioremap() interception based on iotable
contents.
With this patch, the ioremap() interception code can properly translate
addresses only after davinci_soc_info has been initialized. Consequently,
in soc-specific init functions, davinci_common_init() has to happen before any
ioremap() attempts. The da8xx init sequence has been suitably modified to meet
this restriction.
