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]
Sorry, please ignore this mail thread, just found the indentation in PATCH2 is wrong. I'll send a v3 later.
Thanks Zhenzhong
