Hi Maintainers,
May I get a final update on this patchset?
There is only a few days remaining before my layoff at Oracle. I can't
login the mail address after that.
No matter if you prefer to reject it, please let me know. I'd like to
get an end to this patchset.
Thanks
Zhenzhong

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.
