Andreas Arnez 99b7da5d7a S390: Migrate to regcache_supply/collect_regset. 
Rather than supplying own supply/collect functions, use the generic
functions regcache_supply_regset and regcache_collect_regset instead.
The register maps are rewritten accordingly and become much shorter
(and better readable) than before.

Tom Tromey 6a109b6b2c add "this" pointers to more target APIs 
A subsequent pass introduces delegation helper functions to the target
API.  This delegation is much cleaner if the target_ops pointer is
directly available at delegation time.

This patch adds the "this" pointer to various to_* methods for this
purpose.

This updates a number of ports which I am unable to test.  Please give
them a look-over.  Any possible problem here is trivial, though, as
all that is required is adding an argument to a function.

Andreas Arnez 6682d9595e S390: Fix TDB regset recognition 
When checking for the presence of the TDB regset, the current code
interprets ENODATA from PTRACE_GETREGSET as an indication that the TDB
regset *could* occur on this system, but the inferior stopped outside
a transaction.  However, the Linux kernel actually reports ENODATA
even on systems without the transactional execution facility.  Thus
the logic is now changed to check the TE field in the HWCAP as well.

This version also checks the existence of the TDB regset -- just to be
on the safe side when running on TE-enabled hardware with a kernel
that does not offer the TDB regset for some reason.

gdb/
	* s390-linux-nat.c (s390_read_description): Consider the TE field
	in the HWCAP for determining 'have_regset_tdb'.

gdbserver/
	* linux-s390-low.c (HWCAP_S390_TE): New define.
	(s390_arch_setup): Consider the TE field in the HWCAP for
	determining 'have_regset_tdb'.

Ulrich Weigand 0e5fae36f1 S/390: Rename source files to *-linux-* 
As suggested before, rename the S/390-related source files (tdep and nat)
such that "-linux-" occurs in the file name, like with other GNU/Linux
targets.  Since no other operating system is currently supported by GDB
on this architecture, this isn't strictly necessary.  But the old names
sometimes caused GDB contributors to miss these files when performing a
change that affects all GNU/Linux targets.  The latest such incident was
observed here:
