Pull GPIO fixes from Linus Walleij:
 "Here are a few GPIO fixes for v4.8.

  I was expecting some fallout from the new chardev rework but nothing
  like that turned up att all.  Instead a Kconfig confusion that I think
  I have finally nailed, then some ordinary driver noise and trivia.

  This fixes a Kconfig issue with UM: when I made GPIOLIB available to
  all archs, that included UM, but the OF part of GPIOLIB requires
  HAS_IOMEM, so we add HAS_IOMEM as a dependency to OF_GPIO.

  This in turn exposed the fact that a few GPIO drivers were implicitly
  assuming OF_GPIO as their dependency but instead depended on OF alone
  (the typical problem being a pointer inside gpio_chip not existing
  unless OF_GPIO is selected) and then UM would fail to compile with
  these drivers instead.  Then I lost patience and made any GPIO driver
  depending on just OF depend on OF_GPIO instead, that is certainly what
  they meant and the only thing that makes sense anyway.  GPIO with just
  OF but !OF_GPIO does not make sense.

  Also a fix for the max730x driver data pointer, and a minor comment
  fix for the GPIO tools"

Pull perf fixes from Ingo Molnar:
 "Mostly tooling fixes, but also start/stop filter related fixes, a perf
  event read() fix, a fix uncovered by fuzzing, and an uprobes leak fix"

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  perf/core: Check return value of the perf_event_read() IPI

  perf probe: Release resources on error when handling exit paths
  perf probe: Check for dup and fdopen failures
  perf symbols: Fix annotation of objects with debuginfo files
  perf script: Don't disable use_callchain if input is pipe

  perf jitdump: Add the right header to get the major()/minor() definitions
  perf ppc64le: Fix build failure when libelf is not present
  perf tools mem: Fix -t store option for record command
  perf intel-pt: Fix ip compression

We have to check if the values are >= *_MAX, not just >, fix it.

From the bugzilla report:

''In file /tools/perf/util/evsel.c  function __perf_evsel__hw_cache_name
it appears that there is a bug that reads beyond the end of the buffer.
The statement "if (type > PERF_COUNT_HW_CACHE_MAX)" allows type to be
equal to the maximum value. Later, when statement "if
(!perf_evsel__is_cache_op_valid(type, op))" is executed, the function
can access array perf_evsel__hw_cache_stat[type] beyond the end of the
buffer.

It appears to me that the statement "if (type > PERF_COUNT_HW_CACHE_MAX)"
should be "if (type >= PERF_COUNT_HW_CACHE_MAX)"

Bug found with Coverity and manual code review. No attempts were made to
execute the code with a maximum type value.''

perf tools build in recent kernels spews splat when cross compiling with uClibc:

               ^
This is after commit 61a6445e463a31 ("tools lib: Guard the strlcpy() header with
__GLIBC__").

The problem is uClibc also defines __GLIBC__ for exported headers for
applications. So add that specific check to not trip for uClibc.

In order to successfully decode Intel PT traces, context switch events
are needed from the moment the trace starts. Currently that is ensured
by using the 'immediate' flag which enables the switch event when it is
opened.

However, since commit 86c2786994bd ("perf intel-pt: Add support for
PERF_RECORD_SWITCH") that might not always happen. When tracing
system-wide the context switch event is added to the tracking event
which was not set as 'immediate'. Change that so it is.
