Commit 7113a45451a9f656deeff070e47672043ed83664 was clearly not tested.
kimage_alloc_crash_control_page() explicitly chooses a page inside the
crash region and clears it.
However, the sentiment of the commit is certainly desirable, to prevent
accidental playing in the crash region.
As the mappings are removed from Xen's directmap region,
map_domain_page() doesn't work (unless the debug highmem barrier is
sufficiently low that the crash regions ends up above it, and the
virtual address ends up coming from the mapcache).
This means that both here in clear_domain_page(), and later in
machine_kexec_load() where the code is copied in, is vulnerable to this
pagefault.
The solution to this problem which would leave the fewest mappings would
be to have kimage_alloc_crash_control_page() map the individual control
page to the main Xen pagetables, at which a call to point
map_domain_page() on it will work correctly. This would need an
equivalent call to destroy_xen_mappings() in kimage_free().
However, it is far from neat.
I defer to others as to which approach is better, but suggest that one
way or another, the problem gets fixed very quickly, even if that means
taking this complete reversion now and submitting a proper fix in due
course.

I tested this patch earlier and now with latest Xen and kexec-tools commits.
I am not able to reproduce this issue on my machines. Don, could you
provide more details about your system and how did you build your
Xen and kexec-tools (configure, make options, etc.)?
Andrew, David, Did you run kexec tests in your automated test environment
with commit 7113a45451a9f656deeff070e47672043ed83664 applied? Could you
tell something about results?

I am on holiday until 06th January 2014 and I am not able to investigate
this issue deeper right now. If you feel that it is better to revert
this patch and later do second attempt to remove this mapping I do
not object.

Since this commit introduced a regression, a revert is the best thing to
do here.

I guess Daniel tested a debug build without this crashkernel option.
This would place the crash region above the direct mapping region and
map_domain_page() would do the right thing.

This should be made conditional on the location of the crash region --
it is wrong to do this for portions of the crash region that are outside
the crash region.

Presume you mean "outside the direct-map region"?

The last is part of enabling xen crashdump analyser see:
http://lists.xen.org/archives/html/xen-devel/2013-02/msg01606.html
as are the patches:
* 588e9ba Adjust xen-crashdump-analyser info for 4.4.0
* f53550b Add new xen-crashdump-analyser info.
* a1f92d3 Introduce more offsets, and embed all offsets into the symbol file
Attached are these patches including the patch I use to enable rpmbuild
(dcs-xen-54:~/xen>rpmbuild -bb xen-4.4.spec). Not that I expect it to
matter. The "crashkernel=256M@256M" may be the key to reproducing it.
Also attached the complete console output from my test (kexec-broken.txt).

I have no idea on how to even check for "outside the direct-map region"
and how to test any additional changes. Testing with "crashkernel=256M"
((XEN) Kdump: 256MB (262144kB) at 0x82a1be000) does not work before or
after this patch. In both cases, I get an error out of kexec:

Could not find a free area of memory of 0xa000 bytes...
locate_hole failed
I am currently busy with other tasks and so do not expect to get to
learning about xen's direct-map region and/or finding out why kexec does
not work in this case before xen 4.4.0 release date.

I don't agree: Reverting this would imply restoring the issue with
mapping the kexec range even when outside the direct map area.
Furthermore I intend to backport this change, as from all I can
tell prior to your rework of the kexec code it was entirely unused
(and hence should never have been there).

Either that or the kexec code would become independent of the
specific behavioral aspects of the direct map and map_domain_page().
It's the latter that I'd prefer, not the least because I'm getting the
impression that restoring the code (even if conditional) would still not
help when the kexec area is not only outside the direct map area, but
beyond accessible RAM boundaries (i.e. on MFNs for which mfn_valid()
would return false).
