      ARM: dts: sun6i: sina31s: Enable USB OTG controller in peripheral mode · c9c9ac71
      Chen-Yu Tsai authored 
      

While the SinA31s does have a proper 5-pin mini USB OTG port, the ID
pin does not seem to work. The pin used in the schematics is always low,
regardless of the attached OTG cable or SoC internal pin bias settings.

The v1.5 board is missing bias resistors shown in the schematics for
earlier revisions, and the connections of the remaining one does not
match the schematics either.

In addition, VBUS for this port is disconnected from the board's 5V
power rail. The board features a pad to solder jumper pins to connect
VBUS to 5V manually.

Given the above and the fact that the board has 5 more USB host ports,
it makes more sense to have the OTG port work in peripheral mode.

      clocksource: Use a plain u64 instead of cycle_t · a5a1d1c2
      Thomas Gleixner authored 
      

There is no point in having an extra type for extra confusion. u64 is
unambiguous.

Conversion was done with the following coccinelle script:

@rem@
@@
-typedef u64 cycle_t;

@fix@
typedef cycle_t;
@@
-cycle_t
+u64

      cpu/hotplug: Cleanup state names · 73c1b41e
      Thomas Gleixner authored 
      

When the state names got added a script was used to add the extra argument
to the calls. The script basically converted the state constant to a
string, but the cleanup to convert these strings into meaningful ones did
not happen.

Replace all the useless strings with 'subsys/xxx/yyy:state' strings which
are used in all the other places already.

      ARM/imx/mmcd: Fix broken cpu hotplug handling · a051f220
      Thomas Gleixner authored 
      

The cpu hotplug support of this perf driver is broken in several ways:

1) It adds a instance before setting up the state.

2) The state for the instance is different from the state of the
   callback. It's just a randomly chosen state.

3) The instance registration is not error checked so nobody noticed that
   the call can never succeed.

4) The state for the multi install callbacks is chosen randomly and
   overwrites existing state. This is now prevented by the core code so the
   call is guaranteed to fail.

5) The error exit path in the init function leaves the instance registered
   and then frees the memory which contains the enqueued hlist node.

6) The remove function is removing the state and not the instance.

Fix it by:

- Setting up the state before adding instances. Use a dynamically allocated
  state for it.

- Installing instances after the state has been set up

- Removing the instance in the error path before freeing memory

- Removing the instance not the state in the driver remove callback

While at is use raw_cpu_processor_id(), because cpu_processor_id() cannot
be used in preemptible context, and set the driver data after successful
registration of the pmu.

This was entirely automated, using the script by Al:

  PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*<asm/uaccess.h>'
  sed -i -e "s!$PATT!#include <linux/uaccess.h>!" \
        $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h)

to do the replacement at the end of the merge window.
