[PATCH v4 00/37] ldv/unwind: improve stacktrace feature

[Masatake YAMATO]

This patch set is for improving stacktrace feature.
The review result of Dmitry V. Levin <ldv at altlinux.org> are 
reflected.

You can try the patch incremental. About any n (0 < n < 38), you can
apply patches from 1 to n to the source tree, compile it and run ./strace.

Masatake YAMATO (37):
  unwind: fix a bug in range updating of binary search
  unwind: make alloc_mmap_cache unwind.c local
