The only remaining mentions of these addresses are in COPYING files which I
haven't touched.

Some of the changed files are imports from elsewhere, however
filtering them out is tricky, I think it is tolerable to have these
files be modified here and then perhaps reverted on the next sync,
since it's only 1-2 lines and obvious what is going on.

Andrew Cooper 9f378f487a tools/libxc: Improve the *_FIELD() macros
The {GET,SET,MEMCPY,MEMSET_ARRAY}_FIELD() macros previously required
'dinfo->guest_width' to exist in scope, which is somewhat antisocial, and
makes them awkward to use in other contexts.

Update these macros to take guest width as a parameter, and in all cases pass
dinfo->guest_width.

David Vrabel 0a9daad380 libxc: add xc_hvm_param_get/set() to get/set 64-bit values
HVMOP_get_param and HVMOP_set_param take a uint32_t for the parameter
index and a uint64_t for the value.  So add xc_hvm_param_get() and
xc_hvm_param_set() that take the same types.

The existing xc_get_hvm_param() and xc_set_hvm_param() are retained
for compatibility but are deprecated.

Jason Andryuk 84acc84afb libxc: Protect xc_domain_resume from clobbering domain registers
xc_domain_resume() expects the guest to be in state SHUTDOWN_suspend.
However, nothing verifies the state before modify_returncode() modifies
the domain's registers.  This will crash guest processes or the kernel
itself.

This can be demonstrated with `LIBXL_SAVE_HELPER=/bin/false xl migrate`.

Dario Faggioli 0dd5b65410 libxc: introduce xc_domain_get_guest_width()
As a wrapper to XEN_DOMCTL_get_address_size, and use it
wherever the call was being issued directly via do_domctl(),
saving quite some line of code.

Actually, the function returns the guest width in bytes,
rather than directly what XEN_DOMCTL_get_address_size provides
(which is a number of bits), since that is what it is useful
almost everywhere.

tools/libxc, tools/libelf: Relicense under LGPL v2.1

Relicense these two libraries under LGPL v2.1 only except where
individual files already included the "or later" provision.

Copyright holders have been contacted by Stephen Spector and have all
agreed this change.

Removed tools/libxc/ia64/aclinux.h since it appeared to be
unused. There is a separate, more up to date, copy in
xen/include/acpi/platform/aclinux.h which does appear to be used.

Clarify the license of MiniOS privcmd.h under the same terms as other
tools/include/xen-sys headers.

Keir Fraser 5cc436c1d2 libxc: eliminate static variables, use xentoollog; API change
This patch eliminate the global variables in libxenctrl (used for
logging and error reporting).

Instead the information which was in the global variables is now in a
new xc_interface* opaque structure, which xc_interface open returns
instead of the raw file descriptor; furthermore, logging is done via
xentoollog.

There are three new parameters to xc_interface_open to control the
logging, but existing callers can just pass "0" for all three to get
the old behaviour.

All libxc callers have been adjusted accordingly.

Also update QEMU_TAG for corresponding qemu change.

Keir Fraser 9fececad98 libxc: use new (replacement) mmap-batch ioctl
Replace all calls to xc_map_foreign_batch() where the caller doesn't
look at the passed in array to check for errors by calls to
xc_map_foreign_pages(). Replace all remaining calls by such to the
newly introduced xc_map_foreign_bulk().

As a sideband modification (needed while writing the patch to ensure
they're unused) eliminate unused parameters to
uncanonicalize_pagetable() and xc_map_foreign_batch_single(). Also
unmap live_p2m_frame_list earlier in map_and_save_p2m_table(),
reducing the peak amount of virtual address space required.

All supported OSes other than Linux continue to use the old ioctl for
the time being.

Also change libxc's MAJOR to 4.0 to reflect the API change.

The idea is that this file is where we will have two implementations

faster) and the other which does more work to avoid requiring guest
modifications.
