...in paravirt-ops no longer functions in the correct manner after the integration of the hrtimers code. The problem is that now the call path for time initialization is: time_init : late_time_init = hpet_time_init; late_time_init -> hpet_time_init: setup_pit_timer (BAD) do_time_init --> (via paravirt.h) time_init_hook --> (via arch_hooks.h) time_init_hook (in SUBARCH/setup.c) If this isn't confusing enough, the paravirt case goes through an indirect function pointer in the paravirt-ops table.

The following patches introduce the core infrastructure needed to paravirtualize the 32-bit x86 Linux kernel. This is done by moving virtualization sensitive insn's or code paths to a function table, paravirt_ops. This structure can be populated with hypervisor specific calls or native stubs and currently support running on bare metal, VMI, Xen, or Lhype. These patches apply to

This patch series implements the Linux Xen guest in terms of the paravirt-ops interface. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual block
