[Qemu-devel] [PATCH v2 00/16] fixes and improvements

[Aurelien Jarno <aurelien@aurel32.net>]

The two first patches fixes bugs in the target-s390x TCG emulation.

The 3 following patches fix some instruction definition. Given we don't
emulate a given CPU model and check the instruction availability, they
don't provide any functional change.

The 7 following patches emulate some missing instructions, either
from the zArchitecture or from some additional facilities.

The 2 following patches are new in this series, but have been posted as
RFC before. They prepare the work for the following patch (which hasn't
been posted before), providing a huge speed improvements when copying
data between the kernel and userland.

The last patch fixes an issue with the MVC instruction when both memory
areas overlap.

With all these patches applied, the GCC testsuite run in a guest fully
passes.


changes v1 -> v2:
 - dropped patch 3 "rename BRXHLE instruction into BRXLG"
 - fixed FIXBR argument in patch 6
 - add specification exception for odd r1 in patch 8
 - pass more values as arguments in patch 8
 - add the 4 last patches
