Update to v1.3.0-rc1 plus an OOM workaround. Since SPICE v0.12.0 doesn't build on 11.4 due to a missing build dependency, enable SPICE only from 12.1 on. OBS-URL: https://build.opensuse.org/request/show/143323 OBS-URL: https://build.opensuse.org/package/show/Virtualization/qemu?expand=0&rev=119

Subject: [PATCH] linux-user: fix segmentation fault passing with g2h(x) != x

When forwarding a segmentation fault into the guest process, we were passing
|
|
the host's address directly into the guest process's signal descriptor.
|
|
|
|
That obviously confused the guest process, since it didn't know what to make
|
|
of the (usually 32-bit truncated) address. Passing in g2h(address) makes the
|
|
guest process a lot happier.
|
|
|
|
This fixes java running in arm-linux-user for me.
