[Xen-devel] [PATCH v7 00/10] toolstack-based approach to pvhvm guest kexec

[Vitaly Kuznetsov <vkuznets@xxxxxxxxxx>]

This patch series provides x86 PVHVM domains with an ability to perform
kexec/kdump-style operations.

The main change in v7 is the XENMEM_soft_reset->XEN_DOMCTL_soft_reset change of
the newly introduced hypercall.

Changes are mentioned in individual patches. Here is the list of them grouped
by the reviewer's name:

Jan Beulich:
- XENMEM_soft_reset->XEN_DOMCTL_soft_reset change
- print a warning on !mfn_valid case
- check PGC_allocated for pages
- don't re-read page->count_info
- minor structuring change
- pause both source and destination domain while processing the hypercall
- remove nr_transferred from public interface
- other minor fixes in PATCH 04/10
- add a comment on why we don't do two XSM_TARGET checks in dummy.h

Tim Deegan:
- use get_gfn_type_access() in PoD case

Wei Liu:
- replace LIBXL_HAVE_SHUTDWON_REASON_SOFT_RESET with LIBXL_HAVE_SOFT_RESET

Daniel De Graaf:
- add reset_transfer vector to FLASK (I dropped Acked-by: on the patch because
  of the XENMEM_soft_reset->XEN_DOMCTL_soft_reset change.)

Julien Grall:
- check that xc_domain_getinfo() return the domain we asked for
