Most of the processing for each int340x driver to add a thermal zone
is very similar and every driver has to duplicate code.
Created a common module, which exports API to add and remove zones.
In this way, we not only avoid duplicate code but also helps in
bug fixes and enhancements.
If for some driver default processing for thermal zone callback is
not enough they can overide individual callback.
The code for this driver is primarily copied from int3402_thermal.c.

  A lot of these are tweaks and fixes to device trees, fixing various

rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux
settings depending on the card state. This collides with a lot of assumptions.

It only works when using the internal card-detect mechanism and breaks
horribly when using either the normal card-detect via the slot-gpio function
or via any other pin. Also there is of course no link between the mmc and jtag
on the software-side, so the jtag clocks may very well be disabled when the
card is ejected and the soc switches back to the jtag pinmux.

Leaving the switching function enabled did result in mmc timeouts and rcu
stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases,
as we expect the devicetree to explicitly select either mmc or jtag pinmuxes
anyway.

Currently the symbol structure is allocated with symbol_conf.priv_size
to carry sideband information like annotation, map browser on TUI and
sort-by-name tree node.  So retrieving these information from symbol
needs to care about the details of such placement.

However the annotation code just assumes that the symbol is placed after
the struct annotation.  But actually there's other info between them.
So accessing those struct will lead to an undefined behavior (usually a
crash) after they write their info to the same location.

To reproduce the problem, please follow the steps below:

  1. run perf report (TUI of course) with -v option
  2. open map browser (by pressing right arrow key for any entry)
  3. search any function (by pressing '/' key and input whatever..)
  4. return to the hist browser (by pressing 'q' or left arrow key)
  5. open annotation window for the same entry (by pressing 'a' key)

Perf tool fails to unwind user stack if the event raises in a shared
object. This patch improves tests/dwarf-unwind.c to demonstrate the
problem by utilizing commonly used glibc function "bsearch". If perf is
not statically linked, the testcase will try to unwind a mixed call
trace.

By debugging libunwind I found that there is a bug in unwind-libunwind:
it always passes 0 as segbase to libunwind, cause libunwind unable to
locate debug_frame entry fir first level ip address (I add some more
debugging output into libunwind to make things clear):

This patch passes map->start as segbase to dwarf_find_debug_frame(), so
di will be initialized correctly.

In addition, dso and executable are different when setting segbase. This
patch first check whether the elf is executable, and pass segbase only
for shared object.

ARC Linux uses the no legacy syscalls abi and corresponding uClibc headers
statfs defines f_type to be U32 which causes perf build breakage

We need to use lib/hweight.c for that, just like we do for lib/rbtree.c,
so tools need to link hweight.o. For now do it directly, but we need to
have a tools/lib/lk.a or .so that collects these goodies...

When thread__init_map_groups() fails, a new thread should be removed
from the rbtree since it's gonna be freed.  Also update last match cache
only if the function succeeded.

When build with 'make ARCH=x86' and dwarf unwind is on, there is a
compiling error:

   CC       /home/wn/perf/arch/x86/util/unwind-libdw.o
   CC       /home/wn/perf/arch/x86/tests/regs_load.o
 arch/x86/tests/regs_load.S: Assembler messages:
 arch/x86/tests/regs_load.S:65: Error: operand type mismatch for `push'
 arch/x86/tests/regs_load.S:72: Error: operand type mismatch for `pop'
 make[1]: *** [/home/wn/perf/arch/x86/tests/regs_load.o] Error 1
 make[1]: INTERNAL: Exiting with 25 jobserver tokens available; should be 24!
 make: *** [all] Error 2
 ...

Which is caused by incorrectly undefine macro HAVE_ARCH_X86_64_SUPPORT.
'config/Makefile.arch' tests __x86_64__ only when 'ARCH=x86_64'.
However, when building x86_64 kernel, ARCH=x86 is valid and commonly
used. Build systems, such as yocto, uses x86_64 compiler with 'ARCH=x86'
to build x86_64 perf, which causes mismatching.

As __LP64__ is defined for x86_64 as well, we can consolidate the
__x86_64__ check to the __LP64__ check and get rid of the IS_X86_64
IMHO.

(This patch is made by Namhyung Kim when replying my v1 patch:

https://lkml.org/lkml/2015/1/7/17

I modified the code to remove dependency on RAW_ARCH:

https://lkml.org/lkml/2015/1/7/865

Namhyung Kim didn't provide his SOB in his original email. I add
mine only for my modification.)

When it failed to write probe commands to the probe_event file in
debugfs, it needs to propagate the error code properly.  Current code
blindly uses the return value of the write(2) so it always uses
-1 (-EPERM) and it might confuse users.
