After doing a bisect between "good 3.13" and "bad 3.14", I ended up
with this commit:
6145cfe394a7f138f6b64491c5663f97dba12450 is the first bad commit
commit 6145cfe394a7f138f6b64491c5663f97dba12450

x86, kaslr: Raise the maximum virtual address to -1 GiB on x86_64
On 64-bit, this raises the maximum location to -1 GiB (from -1.5 GiB),
the upper limit currently, since the kernel fixmap page mappings need
to be moved to use the other 1 GiB (which would be the theoretical
limit when building with -mcmodel=kernel).

and, indeed, reverting this commit on plain 3.14.1 makes my Xenserver
boot just fine. When reverting the patch, I took the liberty of
ignoring the REJECT in arch/x86/Kconfig.
I am, however, a bit confused that this patch dates back to october
while the breakage only occurred when 3.14 was released.
Greetings
Marc
