I used bad names in my clumsiness when rewriting many board
files to use GPIO descriptors instead of platform data. A few
had the platform_device ID set to -1 which would indeed give
the device name "i2c-gpio".

But several had it set to >=0 which gives the names
"i2c-gpio.0", "i2c-gpio.1" ...

Fix the offending instances in the ARM tree. Sorry for the
mess.

Allwinner fixes for 4.17

Here is a bunch of fixes for merge issues, typos and wrong clocks being
described for simplefb, resulting in non-working displays.

The reason for this error is that the span of MOVABLE_ZONE is extended
to whole node span for future CMA initialization, and, normal memory is
wrongly freed here.  I submitted the fix and it seems to work, but,
another problem happened.

It's so late time to fix the later problem so I decide to reverting the
series.

 "A handful of fixes. I've been queuing them up a bit too long so the
  list is longer than it otherwise would have been spread out across a
  few -rcs.

  In general, it's a scattering of fixes across several platforms,
  nothing truly serious enough to point out.

  There's a slightly larger batch of them for the Davinci platforms due
  to work to bring them back to life after some time, so there's a
  handful of regressions, some of them going back very far, others more
  recent.

  There's also a few patches fixing DT on Renesas platforms since they
  changed some bindings without remaining backwards compatible,
  splitting up describing LVDS as a proper bridge instead of having it
  as part of the display unit.

  We could push for them to be backwards compatible with old device
  trees, but it's likely to regress eventually if nobody's actually
  using said compatibility"

Commit 7771c6645700 ("signal/arm: Document conflicts with SI_USER and
SIGFPE") broke the siginfo structure for userspace triggered signals,
causing the strace testsuite to regress.  Fix this by eliminating
the FPE_FIXME definition (which is at the root of the breakage) and
use FPE_FLTINV instead for the case where the hardware appears to be
reporting nonsense.

Since do_undefinstr() uses get_user to get the undefined
instruction, it can be called before kprobes processes
recursive check. This can cause an infinit recursive
exception.
Prohibit probing on get_user functions.

Prohibit kprobes on do_undefinstr because kprobes on
arm is implemented by undefined instruction. This means
if we probe do_undefinstr(), it can cause infinit
recursive exception.

Prohibit probing on optimized_callback() because
it is called from kprobes itself. If we put a kprobes
on it, that will cause a recursive call loop.
