This patchset tries to improve the s390x emulation by fixing and
improving some instructions. It implement some more instructions, from
the zArchitecture base and from the Extended-Translation Facility 2. The
last patch updates the maximum TCG CPU to z800, as the ETF2 and
Long-Displacement Facility are now both fully implemented.
This patch series is based on the s390x unwind and execute patches
from Richard Henderson and the qemu cpu_models patch from Thomas Huth.
It includes feedback from both.
v1 -> v2:
- add a patch to improve IPTE
- implement local-TLB-clearing in IPTE
- use tcg_gen_atomic_xchg_i32 in TEST AND SET
- use gen_op_movi_cc in TEST ADDRESSING MODE
- use helper_atomic_ldo_be_mmu in LOAD PAIR FROM QUADWORD
- use helper_atomic_sto_be_mmu in STORE PAIR TO QUADWORD
- add a patch to implement COMPARE AND SIGNAL
- rename dest and src into src1 and src3 and check that r1 & r3 are even
in COMPARE LOGICAL LONG EXTENDED
- check that r1 & r2 are even in COMPARE LOGICAL LONG
- check that r1 & r3 are even in COMPARE LOGICAL LONG UNICODE
- move the adj_len_to_page patch before MVCL/MVCLE changes and simplify
the expression a bit
- fix indentation in MOVE LONG UNICODE
- rebase the cpu model upgrade to z800 onto the qemu cpu_models patch
from Thomas Huth and use s390_find_cpu_def to get the z800 model.
