Update to qemu 3.1.0-rc5. Is almost certainly the last rc, so should be same as 3.1.0 final. Putting into devel project 'early' because of SLE and Leap needs, not to get into Factory early. Look for the final 3.1 within a week. OBS-URL: https://build.opensuse.org/request/show/655897 OBS-URL: https://build.opensuse.org/package/show/Virtualization/qemu?expand=0&rev=433

Subject: [PATCH] linux-user: Fake /proc/cpuinfo

Fedora 17 for ARM reads /proc/cpuinfo and fails if it doesn't contain
|
|
ARM related contents. This patch implements a quick hack to expose real
|
|
/proc/cpuinfo data taken from a real world machine.
|
|
|
|
The real fix would be to generate at least the flags automatically based
|
|
on the selected CPU. Please do not submit this patch upstream until this
|
|
has happened.
