Hi Andi, Here's a repost of the paravirt_ops update series I posted the other day. Since then, I found a few potential bugs with patching clobbering, cleaned up and documented paravirt.h and the patching machinery. Overview: add-MAINTAINERS.patch obvious remove-CONFIG_DEBUG_PARAVIRT.patch No longer meaningful or needed. paravirt-nop.patch Clean up nop paravirt_ops functions, mainly to allow the patching machinery to easily identify them. paravirt-pte-accessors.patch Accessors to allow pv_ops to control the content of pagetable entries. paravirt-memory-init.patch Hook into initial pagetable creation. paravirt-fixmap.patch Create a fixmap for early paravirt_ops mappings. shared-kernel-pmd.patch Make the choice of whether the kernel pmd is shared between processes or not a runtime selectable flag. mm-lifetime-hooks.patch Hooks to allow the creation, use and destruction of an mm_struct to be followed. paravirt-patch-rename-paravirt_patch.patch Rename a structure to make its use a bit more clear. paravirt-use-offset-site-ids.patch Use the offsetof each function pointer in paravirt_ops as the basis of its patching identifier. paravirt-fix-clobbers.patch Fix up various register/use clobber problems. This may be 2.6.21 material, but I don't think it will materially affect VMI. paravirt-patchable-call-wrappers.patch Wrap each paravirt_ops call to allow the callsites to be runtime patched. paravirt-document-paravirt_ops.patch Document the paravirt_ops structure itself, the patching mechanism, and other cleanups. paravirt-patch-machinery.patch General patch machinery for use by pv_ops backends to implment patching. paravirt-flush_tlb_others.patch Add a hook for cross-cpu tlb flushing. revert-map_pt_hook.patch Back out the map_pt_hook change. paravirt-kmap_atomic_pte.patch Replace map_pt_hook with kmap_atomic_pte. cleanup-tsc-sched-clock.patch Clean up the tsc-based sched_clock. (I think you already have this.) paravirt-sched-clock.patch Add a hook for sched_clock, so that paravirt_ops backends can report unstolen time for use as the scheduler clock. apply-to-page-range.patch Apply a function to a range of pagetable entries.
