Instead of each library having an own include directory move the
official headers to tools/include instead. This will drop the need to
link those headers to tools/include and there is no need any longer
to have library-specific include paths when building Xen.

Making the population of xen/ depend on the time stamps of a subset of
the headers put there is error prone. The creation of a few dozen
symlinks doesn't take a meaningful amount of time (compared to the
overall building of tools/), and hence - to be on the safe side - should
simply be done always. Convert the goal to a phony one and drop its

The issues are:
* dict.has_key() was completely removed in Py3
* dict.keys() is an iterable rather than list in Py3, so .sort() doesn't work.
* list.sort(cmp=) was deprecated in Py2.4 and removed in Py3.
The has_key() issue is trivially fixed by switching to using the in keyword.
The sorting issue could be trivially fixed, but take the opportunity to
improve the code.
The reason for the sorting is to ensure that "unsigned long" gets replaced
before "long", and the only reason sorting is necessary is because
inttypes[arch] is needlessly a dictionary. Update inttypes[arch] to be a list
of tuples rather than a dictionary, and process them in list order.

Versions of linux privcmd prior to commit dc9eab6fd94d ("return -ENOTTY

-ENOTTY for unimplemented codes. This breaks the error path in
libxenforeignmemory resource mapping, which only translates ENOTTY into
EOPNOTSUPP to inform callers of the need to use an alternative (legacy)
mechanism.
This patch adds a new 'unimplemented' [1] ioctl code into the local
privcmd header which is then used to probe for the appropriate errno to
translate in the resource mapping error path
[1] this is a code that has, so far, never been used in any version of
privcmd and will be added to future versions of the header in the
linux source, to make sure it stays unimplemented.

Current interface to the gntdev in FreeBSD is wrong, and mostly worked
out of luck before the PTI FreeBSD fixes, when kernel and user-space
where sharing the same page tables.
On FreeBSD ioctls have the size of the passed struct encoded in the ioctl
number, because the generic ioctl handler in the OS takes care of
copying the data from user-space to kernel space, and then calls the
device specific ioctl handler. Thus using ioctl structs with variable
sizes is not possible.
The fix is to turn the array of structs at the end of
ioctl_gntdev_alloc_gref and ioctl_gntdev_map_grant_ref into pointers,
that can be properly accessed from the kernel gntdev driver using the
copyin/copyout functions. Note that this is exactly how it's done for
the privcmd driver.

Running "make uninstall" does not remove all installed files, a
situation which might cause link related issues if xen is re-installed
in a different location.
In order to make uninstall correctly remove the files it is best
the process should be done recursively by mirroring each "install"
target with an "uninstall" who removes the installed files.
An exception to this rule is uninstalling the files produced by
"qemu-xen-dir-remote" and "qemu-xen-traditional-dir", which are external
to the project. These projects do not implement an "uninstall" target so
the files have to be removed manually.

Build can fail if stubdom build is run before tools build because:
1. tools/include build uses relative path and depends on XEN_OS
2. stubdom needs tools/include to be built, at which time XEN_OS is
mini-os and corresponding symlinks are created
3. libraries inside tools needs tools/include to be built, at which
time XEN_OS is the host os name, but symlinks won't be created
because they are already there
4. libraries get the wrong headers and fail to build
Since both tools and stubdom build need the public headers, we build
tools/include before stubdom and tools. Remove runes in stubdom and
tools to avoid building tools/include more than once.
Provide a new dist target for tools/include. Hook up the install,
clean, dist and distclean targets for tools/include.
The new arrangement ensures tools build gets the correct headers
because XEN_OS is set to host os when building tools/include. As for
stubdom, it explicitly links to the mini-os directory without relying
on XEN_OS so it should be fine.

Due to the fact that on ARM headers types are substituted to uint64_t and
then uint64_t is also substituted to contain the aligment, this would lead
to some types containing two __align8__ directives. Fix this by first
expanding Xen specific types to uint64_t only, and then replacing all the
uint64_t types to __align8__ uint64_t. This relies on the fact that all
Xen-specific types will have longer names, so they will always be replaced
first.

The foreign header generation blindly replaces 'uint64_t' with '__align8__

most circumstances, but Clang objects to two specific uses.
* Inside a sizeof() expression
* As part of a typecast
An example error looks like:
/local/xen.git/tools/libxc/../../tools/include/xen/foreign/x86_64.h:204:44:
error: 'aligned' attribute ignored when parsing type [-Werror,-Wignored-attributes]
__align8__ uint64_t evtchn_mask[sizeof(__align8__ uint64_t) * 8];

/local/xen.git/tools/libxc/../../tools/include/xen/foreign/x86_64.h:13:36:
note: expanded from macro '__align8__'

This sedary is sufficient to fix all the bad examples without touching any of

Linux is in the process of converting their seconds representation to
64 bits, so in order to support it consistently we should follow suit
(which at some point in quite a few years we'd have to do anyway). To
represent this in struct shared_info we leverage a 32-bit hole in
x86-64's and arm's variant of the structure; for x86-32 guests the only
(reasonable) choice we have is to put the extension in struct
arch_shared_info.
A note on the conditional suppressing the xen_wc_sec_hi helper macro
definition in the ix86 case for hypervisor and tools: Neither of the
two actually need this, and its presence causes the tools to fail to
build (due to the inclusion of both the x86-64 and x86-32 variants of
the header).
As a secondary change, x86's do_platform_op() gets a pointless

The x86 struct arch_shared_info field pfn_to_mfn_frame_list_list
currently contains the mfn of the top level page frame of the 3 level
p2m tree, which is used by the Xen tools during saving and restoring
(and live migration) of pv domains and for crash dump analysis. With
three levels of the p2m tree it is possible to support up to 512 GB of
RAM for a 64 bit pv domain.
A 32 bit pv domain can support more, as each memory page can hold 1024
instead of 512 entries, leading to a limit of 4 TB.
To be able to support more RAM on x86-64 switch to an additional
virtual mapped p2m list.
This patch expands struct arch_shared_info with a new p2m list virtual
address, the root of the page table root and a p2m generation count.
The new information is indicated by the domain to be valid by storing
a non-zero value into the page table root member.
To avoid build failures in the tools directory the checked structure
sizes must be adapted, too.
