[PATCH 00/10] x86/paravirt: several cleanups
This series removes some no longer needed stuff from paravirt infrastructure and puts large quantities of paravirt ops under a new config option PARAVIRT_XXL which is selected by XEN_PV only. A pvops kernel without XEN_PV being configured is about 2.5% smaller with this series applied. tip commit 5800dc5c19f34e6e03b5adab1282535cb102fafd ("x86/paravirt: Fix spectre-v2 mitigations for

[PATCH 00 of 38] xen: add more Xen dom0 support
Hi Ingo, Here''s the chunk of patches to add Xen Dom0 support (it''s probably worth creating a new xen/dom0 topic branch for it). A dom0 Xen domain is basically the same as a normal domU domain, but it has extra privileges to directly access hardware. There are two issues to deal with: - translating to and from the domain''s pseudo-physical addresses and real machine

[PATCH 00/10] paravirt: make amount of paravirtualization configurable
Today paravirtualization is a all-or-nothing game: either a kernel is compiled with no paravirtualization support at all, or it is supporting paravirtualized environments like Xen pv-guests or lguest additionally to some paravirtualized tuning for KVM, Hyperv, VMWare or Xen HVM-guests. As support of pv-guests requires quite intrusive pv-hooks (e.g. all access functions to page table entries,
