I've committed the attached (mainline and 6.2 branch). This also goes
through the MAINTAINERS file marking all affected architectures as
"broken" (so that gdb_mbuild.sh skips them).

* MAINTAINERS: Mark the xstormy16, sh64, ns32k, mn10300, mcore,
and h8300 as broken.
* NEWS: END-OF-LIFE frame compatibility module.
* PROBLEMS: For "Stack backtraces", remove powerpc, hppa and mips
specific comments.

+GDB's internal frame infrastructure has been completely rewritten.
+The new infrastructure making it possible to support key new features
+including DWARF 2 Call Frame Information. To aid in the task of
+migrating old configurations to this new infrastructure, a
+compatibility module, that allowed old configurations to continue to
+work, was also included.
+
+GDB 6.2 will be the last release to include this frame compatibility
+module. This change directly impacts the following configurations:

+h8300-*-*
+mcore-*-*
+mn10300-*-*
+ns32k-*-*
+sh64-*-*
+v850-*-*
+xstormy16-*-*
+
+Unless there is activity to revive these configurations, they will be
+made OBSOLETE in GDB 6.3, and REMOVED from GDB 6.4.
