af2503e223 Fix bug in libunwind-ptrace which can cause reading of random data. 
(maps_next): After reading less than a full buffer of data, copy
remaining data to the top of the buffer so as to maintain the
invariant that all data between mi->buf and mi->buf_end is valid.
This avoids maps_next() parsing uninitialized data.

cbd8648b33 Make libunwind compile with recent versions of GAS. 
Don't test read-only access to F0 and F1 registers --- according to
the SCRA manual, those locations cannot even be expressed in SPILL
descriptors and newer versions of GAS (as well as IAS) won't accept
.spillreg directives targeting those registers.

f176ad6fc6 Bring git v0.98.5 tree in sync with released v0.98.5. 
Sadly, the conversion from Bitkeeper -> CVS -> git wasn't perfect.  Or
so it seems.

bc09a82735 ia64: Allow write-access to UNW_IA64_BSP and UNW_IA64_SP. 
Writing UNW_IA64_BSP and UNW_IA64_SP can wreak havoc if not done
properly but can also be extremely useful when done correctly.  For
example, the Linux kernel can use this to update a cursor with the
MIN_STATE info which is saved by firmware due to an MCA or INIT event.

2c08119b53 ia64: Drop early-out-on-zero-IP from unw_step() 
The early-out causes problems in the kernel, which wants to unwind to the

3b7eb49469 ia64: Introduce rbs_get_base() to simplify Linux kernel integration. 
In the Linux kernel, we want to track the size of all register-backing stores
so we can protect against illegal memory accesses.  Enable this by introducing
an rbs_get_base() macro.
