By default pciback only allows PV guests to write "known safe" values into
PCI config space. But many devices require writes to other areas of config
space in order to operate properly. One way to do that is with the "quirks"
interface, which specifies areas known safe to a particular device; the
other way is to mark a device as "permissive", which tells pciback to allow
all config space writes for that domain and device.
This adds a "permissive" flag to the libxl_pci struct and teaches libxl how
to write the appropriate value into sysfs to enable the permissive feature for
devices being passed through. It also adds the permissive config options either
on a per-device basis, or as a global option in the xl command-line.
Because of the potential stability and security implications of enabling
permissive, the flag is left off by default.

Config parsing functions do not properly belong in libxl. Move them into

Upstream the "xen/acpi-processor: C and P-state driver that
uploads said data to hypervisor." takes care of uploading power information
information that normally a cpu frequency scaling driver would using
in the initial domain. We want the hypervisor to take that data and
make good usage of it.
Fortunatly for us we do not have to worry about the native cpu frequency
scaling drivers being loaded first, as the upstream commit:
"xen/cpufreq: Disable the cpu frequency scaling drivers from loading."
takes care of that. Meaning we can load the xen-acpi-processor at any time.
By default that driver is built as a module - and since we are
the only user of it - we should load it.

One of the bottlenecks with foreign page-in request is the poor retry
handling in linux_privcmd_map_foreign_bulk(). It sends one request per
paged gfn at a time and it waits until the gfn is accessible. This
causes long delays in mmap requests from qemu-dm and xc_save.
Instead of sending one request at a time, walk the entire gfn list and
send batches of mmap requests. They will eventually end up in the pager's
request ring (if it has room again), and will fill up this ring so that
in turn the pager can also process page-in in batches.
