Import patches-unapplied version 4.7.0-0ubuntu1 to ubuntu/yakkety-proposed
Imported using git-ubuntu import.
Changelog parent: 38cdaf6a6157895d96dc9845570fa78d74b5207c
New changelog entries:
* Rebasing to upstream Xen release 4.7 (LP: #1621618)
- Renamed all *-4.6* files into *-4.7*. Also moved references within
various files from 4.6 to 4.7.
- Follow previous abiname patches to create individual run-time libs
for the versioned libxen package for libxencall, libxenevtchn,
libxenforeignmemory, libxengnttab, and libxentoollog.
- Modified debian/libxen-dev.install to pick up the additional headers
and drop one which is no longer present. And also add the new libs.
- Refreshed Debian patchesS
- Dropped transitional packages <4.6, added a set for 4.6.
- Dropped tools-allow-configure-time-choice-of-libexec-subdire.patch
(upstream)
- Dropped ubuntu-config-prefix-fix.patch (unnecessary)
- Dropped all security patches since those were all included in
the new upstream release.
- Added fix for FTBS on Arm due to unused static variables and
hardening flags turned on.
- Switched dependencies of sysvinit scripts from libvirt-bin to
libvirtd.
- Added modprobe for xen-acpi-processor (no auto-load alias) to
xenstrore init script. Otherwise there is no frequency scaling
if the driver is compiled as a module.
- Added proposed upstream fix for regression to save PV guests
with more than 1G of memory.
