  perf hists browser: Add back callchain folding symbol (2012-10-17 13:54:08 -0300)

----------------------------------------------------------------
perf/urgent fixes:

. The python binding needs to link with libtraceevent and to initialize
  the 'page_size' variable so that mmaping works again.

. The callchain folding character that appears on the TUI just before
  the overhead had disappeared due to recent changes, add it back.

. Intel PEBS in VT-x context uses the DS address as a guest linear address,
  even though its programmed by the host as a host linear address. This either
  results in guest memory corruption and or the hardware faulting and 'crashing'
  the virtual machine.  Therefore we have to disable PEBS on VT-x enter and
  re-enable on VT-x exit, enforcing a strict exclude_guest.

  Kernel side enforcement fix by Peter Zijlstra, tooling side fix by David Ahern.

. Fix build on sparc due to UAPI, fix from David Miller.

. Fixes for the srclike sort key for unresolved symbols and when processing
  samples in JITted code, where we don't have an ELF file, just an special
  symbol table, fixes from Namhyung Kim.

. Fix some leaks in libtraceevent, from Steven Rostedt.
