[qemu-s390x] [PATCH v1 0/2] s390x/tcg: STFLE fixes

[David Hildenbrand]

While testing vector instructions, I ran into various issues with
user space binaries compiled with more recent compiler versions like

# gunzip /usr/share/man/man1/hexdump.1.gz
<dhildenb> *** stack smashing detected ***: <unknown> terminated

Turns out:
a) the STFLE instruction in semi-broken on the first invocation
b) the code expects a different STFLE behavior than documented in the PoP

Fix a) and make sure the code works by adjusting b).

David Hildenbrand (2):
  s390x/tcg: Fix max_byte detection for stfle
  s390x/tcg: Store only the necessary amount of doublewords for STFLE
