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.

2bc0aee843 ia64: Allow r1 to be saved in an ABI-specific frame. 
This makes core-dumps contain the proper (user-level) value for r1
when using libunwind in the kernel.

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
end of the kernel-stack (i.e., until IP==0) and then access the user-level
state.

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.
