Subject[PATCH RFC 0/3] x86/xen: pvclock vdso support
Date
Hey!

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!

Thanks,
Joao
