[RFC v3 0/8] Support for Linux kernel debugging

[Philipp Rudo <prudo@linux.vnet.ibm.com>]

Hi everybody

here is v3 of the patch series.  Andreas also pushed it to a new branch
(users/arnez/lk3) on Sourceware.

To make colaboration easier and prevent merge conflicts we (Peter, Yao,
Andreas and I) decided to take v3 as the basis for further development.
That means future patches will be added on top of the branch and finally
merged to reasonable patches once the feature is ready to go upstream.  I
hope there are no objections against this procedure.

New in v3:
	* Rebase to current master.
	* configure.tgt: Fix build bug when not compiled with
	--enable-targets=all.
	* Makefile.in: Move all lk-*.o files to ALL_TARGET_OBS.
	* lk-low.c (lk_init_addr): Use lookup_minimal_symbol instead of parser.
	(lk_init_struct): Use lookup_symbol instead of parser.
	(lk_init_field): Adjust calling signature.
	(lk_fetch_registers): Use ptid from regcache instead of inferior_ptid.
	* lk-low.h: Adjust LK_*_FIELD macros.
