The series improves the kexec hypercall by making Xen responsible for
loading and relocating the image. This allows kexec to be usable by
pv-ops kernels and should allow kexec to be usable from a HVM or PVH
privileged domain.
The first patch is a simple clean-up.
The second patch allows hypercall structures to be ABI compatible
between 32- and 64-bit guests (by reusing stuff present for domctls
and sysctls). This seems better than having to keep adding compat
handling for new hypercalls etc.
Patch 3 introduces the new ABI.
Patch 4 and 5 nearly completely reimplement the kexec load, unload and
exec sub-ops. The old load_v1 sub-op is then implemented on top of
the new code.
Patch 6 calls the kexec image when dom0 crashes. This avoids having
to alter dom0 kernels to do a exec sub-op call on crash -- an existing
SHUTDOWN_crash.
Patches 7 and 8 add the libxc API for the kexec calls.
The required patch series for kexec-tools will be posted shortly.
