CLPS711X CPUs have 128 bytes of on-chip Boot ROM with an
instruction sequence that configure UART1 to receive up to
2 Kbytes of serial data which is then placed in the on-chip
SRAM. Once the download is complete, the program counter
jumps to SRAM to begin executed the downloaded data.
The purpose of this mode is to allow the downloaded code to
facilitate programming of FLASH or other ROM device. Selection
of the internal Boot ROM is accomplished at power-on-reset time.
No reason to keep this special (develop only) mode in the kernel.

This cleanup series gets rid of <mach/timex.h> for platforms not using
ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
387798b3 (ARM: initial multiplatform support).)

To make this work some code out of arch/arm needed to be adapted. The
respective changes got acks by their maintainers to be taken via armsoc

Compared to the previous pull request there was another patch added that

Signed-off-by: Olof Johansson <olof@lixom.net>

In commit f0402f9b ("ARM: ixp4xx: stop using <mach/timex.h>")
I didn't intend to implement a functional change, but as Olof noticed I
failed---at least a bit. Before this commit the following was used to
determine the latch value used:

	#define IXP4XX_TIMER_FREQ 66666000
	#define CLOCK_TICK_RATE \
		(((IXP4XX_TIMER_FREQ / HZ & ~IXP4XX_OST_RELOAD_MASK) + 1) * HZ)
	#define LATCH ((CLOCK_TICK_RATE + HZ/2) / HZ)

The complicated calculation was done "b/c the timer register ignores the
bottom 2 bits of the LATCH value." With HZ=100 CLOCK_TICK_RATE used to
calculate to 66666100 and so LATCH to 666661. In ixp4xx_set_mode the
term

	LATCH & ~IXP4XX_OST_RELOAD_MASK

was used to write to the relevant register (with IXP4XX_OST_RELOAD_MASK
being 3) and so effectively 666660 was used.

In commit f0402f9b I translated that to:

	#define IXP4XX_TIMER_FREQ 66666000
	#define IXP4XX_LATCH DIV_ROUND_CLOSEST(IXP4XX_TIMER_FREQ, HZ)

which results in the same register writes, but still doesn't bear in
mind that the two least significant bits cannot be specified (which is
relevant only when HZ or IXP4XX_TIMER_FREQ are changed).

Instead of reverting back to the old approach use a more obvious and
also more correct way to calculate LATCH. (Regarding the more
correct claim: With IXP4XX_TIMER_FREQ == 66665999, the old code resulted
in LATCH = 666657 corresponding to a cycle time of 0.009999940149400597
seconds (error: -6.0e-8 s) while the new approach results in LATCH =
666660 and so a cycle time of 0.010000000150001503 seconds
(error: 1.5e-10 s).)

  of: search the best compatible match first in __of_match_node()
  Revert "OF: base: match each node compatible against all given matches first"

Currently, of_match_node compares each given match against all node's
compatible strings with of_device_is_compatible.

To achieve multiple compatible strings per node with ordering from
specific to generic, this requires given matches to be ordered from
specific to generic. For most of the drivers this is not true and also
an alphabetical ordering is more sane there.

Therefore, this patch introduces a function to match each of the node's
compatible strings against all given compatible matches without type and
name first, before checking the next compatible string. This implies
that node's compatibles are ordered from specific to generic while
given matches can be in any order. If we fail to find such a match
entry, then fall-back to the old method in order to keep compatibility.

Pull twi tracing fixes from Steven Rostedt:
 "Two urgent fixes in the tracing utility.

  The first is a fix for the way the ring buffer stores timestamps.
  After a restructure of the code was done, the ring buffer timestamp
  logic missed the fact that the first event on a sub buffer is to have
  a zero delta, as the full timestamp is stored on the sub buffer
  itself.  But because the delta was not cleared to zero, the timestamp
  for that event will be calculated as the real timestamp + the delta
  from the last timestamp.  This can skew the timestamps of the events
  and have them say they happened when they didn't really happen.
  That's bad.

  The second fix is for modifying the function graph caller site.  When
  the stop machine was removed from updating the function tracing code,
  it missed updating the function graph call site location.  It is still
  modified as if it is being done via stop machine.  But it's not.  This
  can lead to a GPF and kernel crash if the function graph call site
  happens to lie between cache lines and one CPU is executing it while
  another CPU is doing the update.  It would be a very hard condition to

For non compressed extents, iterate_extent_inodes() gives us offsets
that take into account the data offset from the file extent items, while
for compressed extents it doesn't. Therefore we have to adjust them before
placing them in a send clone instruction. Not doing this adjustment leads to
the receiving end requesting for a wrong a file range to the clone ioctl,
which results in different file content from the one in the original send
root.
