The integrated annotation feature is supported only in TUI mode. Also
it should be enabled with 'symbol' sort key otherwise resulting hist
entry doesn't need to have same symbol as of a sample so that it can
fail on hist_entry__inc_addr_samples with -ERANGE.
You can easily see it when start perf report TUI without symbol* sort
key. This patch fixes the problem.

Fix kprobes/x86 to support jprobes on ftrace-based kprobes.
Because of -mfentry support of ftrace, ftrace is now put
on the beginning of function where jprobes are put.
Originally ftrace-based kprobes doesn't support jprobe
because it will change regs->ip and ftrace doesn't support
changing IP and ftrace itself doesn't conflict jprobe.
However, ftrace -mfentry support moves mcount call on the
top of functions where jprobes are put. This means that
jprobe always conflicts with ftrace-based kprobe and fails.
This patch allows ftrace-based kprobes to support jprobes
by allowing to modify regs->ip and kprobes breakpoint
handler also allows to skip singlestepping because there
is a ftrace call (not an original instruction).

Tracepoints declare a static inline trace_*_rcuidle variant of the trace
function, to support safely generating trace events from the idle loop.
Module code never actually uses that variant of trace functions, because
modules don't run code that needs tracing with RCU idled. However, the
declaration of those otherwise unused functions causes the module to
reference rcu_idle_exit and rcu_idle_enter, which RCU does not export to
modules.
To avoid this, don't generate trace_*_rcuidle functions for tracepoints
declared in module code.

perf defines both __used and __unused variables to use for marking
unused variables. The variable __used is defined to
__attribute__((__unused__)), which contradicts the kernel definition to
__attribute__((__used__)) for new gcc versions. On Android, __used is
also defined in system headers and this leads to warnings like: warning:
'__used__' attribute ignored
__unused is not defined in the kernel and is not a standard definition.
If __unused is included everywhere instead of __used, this leads to
conflicts with glibc headers, since glibc has a variables with this name
in its headers.
The best approach is to use __maybe_unused, the definition used in the
kernel for __attribute__((unused)). In this way there is only one
definition in perf sources (instead of 2 definitions that point to the
same thing: __used and __unused) and it works on both Linux and Android.
This patch simply replaces all instances of __used and __unused with
__maybe_unused.

Storing data for VDSO shared object, because we need it for the post
unwind processing.
The VDSO shared object is same for all process on a running system, so
it makes no difference when we store it inside the tracer - perf.
When [vdso] map memory is hit, we retrieve [vdso] DSO image and store it
into temporary file.
During the build-id processing phase, the [vdso] DSO image is stored in
build-id db, and build-id reference is made inside perf.data. The
build-id vdso file object is called '[vdso]'. We don't use temporary
file name which gets removed when record is finished.
During report phase the vdso build-id object is treated as any other
build-id DSO object.
Adding following API for vdso object:
bool is_vdso_map(const char *filename)
- returns true if the filename matches vdso map name
struct dso *vdso__dso_findnew(struct list_head *head)
- find/create proper vdso DSO object
vdso__exit(void)
- removes temporary VDSO image if there's any
This change makes backtrace dwarf post unwind possible from [vdso] maps.
Following output is current report of [vdso] sample dwarf backtrace:
# Overhead Command Shared Object Symbol
# ........ ....... ................. .............................

Some type definitions are missing from Android or are already defined in
bionic and lead to redefinition errors.
Android defines in types.h __le32. Since perf is wrapping <linux/types.h> with a
local version, we need to define this constant in the local version too.

perf is currently including magic.h directly from the kernel. If the
glibc magic.h is also included, this leads to warnings that the
constants are redefined. This happens on some systems (e.g. Android).
Redefinition errors on Android:

Only two constants from magic.h are used by perf (DEBUGFS_MAGIC and
SYSFS_MAGIC). This fix provides a wrapper for magic.h that includes only
these constants instead of including the kernel header file directly.

Pull DMA-mapping fixes from Marek Szyprowski:
"Another set of fixes for ARM dma-mapping subsystem.
Commit e9da6e9905 replaced custom consistent buffer remapping code
with generic vmalloc areas. It however introduced some regressions
caused by limited support for allocations in atomic context. This
series contains fixes for those regressions.
For some subplatforms the default, pre-allocated pool for atomic
allocations turned out to be too small, so a function for setting its
size has been added.
Another set of patches adds support for atomic allocations to
IOMMU-aware DMA-mapping implementation.
The last part of this pull request contains two fixes for Contiguous
Memory Allocator, which relax too strict requirements."
* 'fixes-for-3.6' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:
ARM: dma-mapping: IOMMU allocates pages from atomic_pool with GFP_ATOMIC
ARM: dma-mapping: Introduce __atomic_get_pages() for __iommu_get_pages()
ARM: dma-mapping: Refactor out to introduce __in_atomic_pool
ARM: dma-mapping: atomic_pool with struct page **pages
ARM: Kirkwood: increase atomic coherent pool size
ARM: DMA-Mapping: print warning when atomic coherent allocation fails
ARM: DMA-Mapping: add function for setting coherent pool size from platform code
ARM: relax conditions required for enabling Contiguous Memory Allocator
mm: cma: fix alignment requirements for contiguous regions
Now that the 2 offenders are fixed, the BIONIC conditional around
libgen.h can be removed.

When a field separator is given, the output format doesn't need to be
fancy like aligning to column length, coloring the percent value and so

Current hist print functions are messy because it has to consider many
of command line options and the code doing that is scattered around to
places. So when someone wants to add an option to manipulate the hist
output it'd very easy to miss to update all of them in sync. And things
getting worse as more options/features are added continuously.
So I'd like to refactor them using hpp formats and move common code to
ui/hist.c in order to make it easy to maintain and to add new features.
