f15e3c25a1 libperf: Add PERF_RECORD_KSYMBOL 'struct ksymbol_event' to perf/event.h

header include.

In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
events to their generic '__u*' versions.

Perf added 'u*' types mainly to ease up printing __u64 values
as stated in the linux/types.h comment:

  /*
   * We define u64 as uint64_t for every architecture
   * so that we can print it with "%"PRIx64 without getting warnings.
   *
   * typedef __u64 u64;
   * typedef __s64 s64;
   */

Add and use new PRI_lu64 and PRI_lx64 macros for that.  Use extra '_' to
ease up the reading and differentiate them from standard PRI*64 macros.

003c66fec2 libperf: Add PERF_RECORD_THROTTLE 'struct throttle_event' to perf/event.h 
Move the PERF_RECORD_THROTTLE event definition into libperf's event.h
header include.

In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
events to their generic '__u*' versions.

Perf added 'u*' types mainly to ease up printing __u64 values as stated
in the linux/types.h comment:

  /*
   * We define u64 as uint64_t for every architecture
   * so that we can print it with "%"PRIx64 without getting warnings.
   *
   * typedef __u64 u64;
   * typedef __s64 s64;
   */

Add and use new PRI_lu64 and PRI_lx64 macros for that.  Use extra '_' to
ease up the reading and differentiate them from standard PRI*64 macros.

leaving it aside on 32-bit arches.

d9c5c08341 libperf: Fix alignment trap with xyarray contents in 'perf stat' 
Following the patch 'perf stat: Fix --no-scale', an alignment trap
happens in process_counter_values() on ARMv7 platforms due to the
attempt to copy non 64 bits aligned double words (pointed by 'count')
via a NEON vectored instruction ('vld1' with 64 bits alignment
constraint).

This patch sets a 64 bits alignment constraint on 'contents[]' field in
'struct xyarray' since the 'count' pointer used above points to such a
structure.

b81d39c7a1 libperf: Fix arch include paths 
Guenter Roeck reported problem with compilation when the ARCH is

  fatal error: asm/cmpxchg.h: No such file or directory

The problem is that we don't use SRCARCH (the sanitized ARCH version)
and we don't get the proper include path.
