6203f1cd0f Cleanup a mapped elf image. 
Without this, we end up with mmap leaks. Thanks to Humberto Abdelnur
for suggesting this.

1eddefc371 [ARM] This patch add some missing bits on ARM platform. 
* src/arm/unwind_i (arm_lock, arm_local_resume): Define.
 * src/ptrace/_UPT_find_proc_info.c: Handle ARM like X86 etc.
 * tests/flush-cache.S (flush_cache): Add (dummy) ARM-version.
	ARM does need executable stack, even on Linux...

3842dac733 Add initial ARM and MIPS support. To support this, also enable the 
reading of .debug_frame sections (used in lieu of .eh_frame sections
when they're not available).

e6b9f350f7 Introduce a tdep_get_func_addr_hook() in the ELF lookup_symbol() 
routine and add address-space argument.  This is needed because on
PPC64, a the function-name symbol refers to a function descriptor
(unlike, for example, on ia64, where the @fptr() operator is needed to
refer to a function descriptor).  Thus, in order to look up the name
of a function, we need to dereference the function descriptor.  To
make matters more "interesting", the function descriptors are normally
resolved by the dynamic linker, so we can't get their values from the
ELF file.  Instead, we have to read them from the running image, hence
the need for the address-space argument.

8c94e12429 (_UPT_find_proc_info): Fix potential crash due to uninitialized pointer. 
Be sure to clear pi->unwind_info when looking up the kernel table and
not needing the unwind-info.  Otherwise, _UPT_put_unwind_info() may
erroneously call free() on the pointer, even though that space wasn't
malloc'd, leading to crashes..
