Pull ACPI fixes from Rafael Wysocki:
 "They fix an ACPI thermal management regression introduced by a recent
  FADT handling cleanup, an ACPI tools build issue introduced by a
  recent ACPICA commit and a PCC mailbox initialization bug causing
  lockdep to complain loudly.

  Specifics:

   - Revert a recent ACPICA cleanup that attempted to get rid of all
     FADT version 2 legacy, but broke ACPI thermal management on at
     least one system (Rafael Wysocki).

   - Fix cross-compiled builds of ACPI tools that stopped working after
     a recent cleanup related to the handling of header files in ACPICA
     (Lv Zheng).

   - Fix a locking issue in the PCC channel initialization code that
     invokes devm_request_irq() under a spinlock (among other things)
     and causes lockdep to complain (Hoan Tran)"

Avoid breaking cross-compiled ACPI tools builds by rearranging the
handling of kernel header files.

This patch also contains OUTPUT/srctree cleanups in order to make above fix
working for various build environments.

perf hists: Fix column length on --hierarchy

2016-11-09T14:55:29+00:00

Markus reported that there's a weird behavior on perf top --hierarchy
regarding the column length.

Looking at the code, I found a dubious code which affects the symptoms.
When --hierarchy option is used, the last column length might be
inaccurate since it skips to update the length on leaf entries.

I cannot remember why it did and looks like a leftover from previous
version during the development.

Anyway, updating the column length often is not harmful.  So let's move
the code out.

perf hists browser: Fix column indentation on --hierarchy

2016-11-09T14:45:58+00:00

When horizontall scrolling is used in hierarchy mode, the the right most
column has unnecessary indentation.  Actually it's needed only if some
of left (overhead) columns were shown.

perf hists browser: Show folded sign properly on --hierarchy

2016-11-09T14:30:47+00:00

When horizontal scrolling is used in hierarchy mode, the folded signed
disappears at the right most column.

Committer note:

To test it, run 'perf top --hierarchy, see the '+' symbol at the first
column, then press the right arrow key, the '+' symbol will disappear,
this patch fixes that.

perf hist browser: Fix hierarchy column counts

2016-11-09T14:19:28+00:00

The perf report/top on TUI supports horizontal scrolling using LEFT and
RIGHT keys.

But it calculate the number of columns incorrectly when hierarchy mode
is enabled so that keep pressing RIGHT key can make the output
disappeared.

In the hierarchy mode, all sort keys are collapsed into a single column,
so it needs to be applied when calculating column numbers.
