There are cases folks want to disable spinlock optimization for debug/test purpose. Xen and hyperv already have parameters "xen_nopvspin" and "hv_nopvspin" to support that, but kvm doesn't.
The first patch adds that feature to KVM guest with "nopvspin".
For compatibility reason original parameters "xen_nopvspin" and "hv_nopvspin" are retained and marked obsolete.
v2: PATCH1: pick the print code change into seperate PATCH2, updated patch description [Vitaly Kuznetsov] PATCH2: new patch with print code change [Vitaly Kuznetsov] PATCH3: add Reviewed-by [Juergen Gross]
Thanks Zhenzhong
