    Fix a typo in oprofile_android

    The typo (in specifying the --kernel-range argument) completely breaks
    kernel profiling  because the kernel end address will always be 0
    and < the start address. All kernel samples will therefore be discarded.
    
    I've also added very basic support for turning on kernel profiling via
    this script.

  1. Improve oprofile scripts.

    Now support importing dumps and running reports using a simple script.
    Eliminated some spurious errors and warnings in the oprofile tools
    when profiling Android libraries.

  1. Reenable oprofile host build.

    Now taking into account differences in the library dependencies of
    libintl on darwin vs. linux.  On darwin, we need to link with libiconv
    which is provided as a shared library on the platform.  On linux,
    iconv is included in libc so we don't need anything special.

  1. Improve oprofile wrapper commands.

    Added a new wrapper script that will help automate more of the process
    of setting up and running oprofile on a remote device.  There is
    more work to be done here once the kernel perf event issues that hinder
    reliability (bug: 2975913) are resolved.

  1. Sync with oprofile CVS HEAD from Jan 11, 2011.

    There have been a few patches to oprofile for newer ARM architectures
    since 0.9.6.
    
    Pruned out irrelevant auto-generated files from the previous dump
    so this is closer to being a mirror of the actual oprofile repository.

  2. Compile oprofile tools on the host.

    Some of the new build targets are disabled for now because libbfd is
    not currently provided by the prebuilt toolchain for all platforms.

    x86: Fix oprofile compilation in pic mode.

    This patch modifies the inline x86 assembly fragments to properly
    save ebx when calling the cpuid instruction. Otherwise, the compiler
    will error, complaining that the PIC register (ebx) is clobbered.

  1. oprofile 0.9.6

    Copy in the rest of the oprofile 0.9.6 tree so we have a source
    copy to match the prebuilt binaries that are checked into
    external/.

  1. oprofile fix for hashing backtraces.

    Oprofile's hash function uses a 64-bit value for the
    key where the high 32-bit are the 'from' address in a backtrace,
    and the low 32-bits are the current PC. However, the hash
    function was:
    
      uint32_t temp = (value >> 32) ^ value;
      return ((temp << 0) ^ (temp >> 8)) & data->hash_mask;
    
    If 'from' and 'to' are the same (recursive function), this hashes
    to 0, and you end up with lots of collisions, turning the
    theoretically O(1) operation into O(n).
    
    To fix it, I just drop the high 32-bits from the hash:
    
      uint32_t temp = value & 0xffffffff;
      return ((temp << 0) ^ (temp >> 8)) & data->hash_mask;
    
    In testing, this drastically reduces the oprofile overhead
    for some tracing.
