Re: RFA: ia64 portion of libunwind patch updated

["J. Johnston" <jjohnstn@redhat.com>]

In light of the recent checked-in patches concerning libunwind and the resolved 
issues, is the ia64-tdep.c patch ok now?  The issue regarding whether libunwind 
could more efficiently reference the table entries will require an ABI change to 
libunwind and needs some thought from David.
