This series proposes support for pvclock vdso under Xen: Patch 1 adds setting cpu 0 pvti page; Patch 2 registers the pvti page with Xen and sets it accordingly in pvclock and Patch 3 adds a Kconfig option since Xen doesn't yet support the PVCLOCK_TSC_STABLE_BIT flag. Though its support will probably be discussed in another RFC I sent[0]. Any comments or suggestions are welcome!
