This is a follow-up to patch 2 of the series called "S390: Fixes for
gdbserver on targets with TDB". The last version of that patch was
here:
https://sourceware.org/ml/gdb-patches/2014-12/msg00021.html
This new version is split up in three patches and contains the following
changes:
* Invalidate the register cache whenever we are about to fetch the
register values from the inferior.
* Instead of passing NULL to the regset store function upon ENODATA from
ptrace, just suppress its invocation, since the registers are now
"unavailable" by default. Consequently no longer handle NULL in
s390_store_tdb or arm_store_wmmxregset.
* Suppress calling the register store function upon other errors from
ptrace as well.
* Rephrase the while()-loops as for()-loops in regsets_fetch_- and
-_store_inferior_registers, for improved readability.
Tested on S390 and i386.
