From: Jeremy Fitzhardinge <jeremy.fitzhardinge at citrix.com> This series replaces the existing paravirtualized spinlock mechanism with a paravirtualized ticketlock mechanism. (targeted for 3.5 window) Changes in V7: - Reabsed patches to 3.4-rc3 - Added jumplabel split patch (originally from Andrew Jones rebased to 3.4-rc3 - jumplabel changes from Ingo and Jason taken and now using

This series replaces the existing paravirtualized spinlock mechanism with a paravirtualized ticketlock mechanism. The series provides implementation for both Xen and KVM. The current set of patches are for Xen/x86 spinlock/KVM guest side, to be included against -tip. I 'll be sending a separate patchset for KVM host based on kvm tree. Please note I have added the below performance result

This series replaces the existing paravirtualized spinlock mechanism with a paravirtualized ticketlock mechanism. The series provides implementation for both Xen and KVM. Changes in V10: Addressed Konrad's review comments: - Added break in patch 5 since now we know exact cpu to wakeup - Dropped patch 12 and Konrad needs to revert two patches to enable xen on hvm 70dd4998, f10cd522c -

This series replaces the existing paravirtualized spinlock mechanism with a paravirtualized ticketlock mechanism. The series provides implementation for both Xen and KVM. Changes in V11: - use safe_halt in lock_spinning path to avoid potential problem in case of irq_handlers taking lock in slowpath (Gleb) - add a0 flag for the kick hypercall for future extension (Gleb) - add stubs for
