Hi Paolo and/or Thomas,

so, here's the second try of the first pull request from me :)

v2:
---
* pick up a new version of Nina's spec_ex series to fix clang compiler issue and
  missing barrier.

Changes in this pull request:

* Marc contributed a series with a few fixes. Most importantly, it generates
  linker scripts for s390x with the assembler, permitting the use of defines in
  linker scripts.
  It is worth noting that it also touches lib/linux/const.h to check for
  __ASSEMBLY__ and __ASSEMBLER__.
* Nina contributed quite a few tests for misalignments in various instructions.
  As well as tests for execute-type instructions. Note that a few of her tests
  will require recent QEMUs under TCG. Upstream fixes are available [1, 2].
* Thomas contributed a test for vSIE on s390x, where the g3 clock might
  sometimes we wrong after reboot. A kernel patch is required[3].
* And, finally, the patch where I get the honor to work as maintainer.
