[PATCH 00/12] Regset rework preparations part 2

[Andreas Arnez <arnez@linux.vnet.ibm.com>]

Now that part 1 of the regset rework preparations has been integrated
(https://sourceware.org/ml/gdb-patches/2014-05/msg00239.html), I'd
like to continue with part 2.

This part adds a collect_regset method to all Linux regsets where it
had been missing.  This is necessary, but not sufficient, to make the
"gcore" command multi-arch capable for the affected targets.  When
this part is approved, I can provide a follow-on patch set that fills
the remaining gaps to multi-arch capable core file handling for all
Linux targets.

Another goal is to make regset handling more similar across
architectures.  Therefore the first patch in this series introduces
generic regset_supply/collect functions, and several of the following
patches exploit them.  Last time I posted this, Mark Kettenis
indicated a need for discussing these functions' interfaces, and I
tried to explain my reasons for the suggested choice:
https://sourceware.org/ml/gdb-patches/2014-05/msg00043.html.

Andreas Arnez (12):
  regcache: Add functions suitable for regset_supply/collect.
  S390: Migrate to regcache_supply/collect_regset.
  AARCH64 Linux: Fill 'collect_regset' in regset structures.
  ALPHA Linux: Fill 'collect_regset' in regset structures.
  FRV Linux: Fill 'collect_regset' in regset structures.
  HPPA Linux: Fill 'collect_regset' in regset structures.
  M32R Linux: Fill 'collect_regset' in regset structure.
  NIOS2 Linux: Fill 'collect_regset' in regset structure.
  SCORE: Fill 'collect_regset' in regset structure.
  TILEGX Linux: Fill 'collect_regset' in regset structure.
  M68K Linux: Define regset structures.
  IA64 Linux: Define regset structures.
