Oh ... I forgot to add: This only applies to running Linux under X
dules separately to enable the use of PV
drivers with unmodified bare-metal kernels.

or not: If you load a crash kernel with kexec, it will be used, otherwise
the hypervisor facility is used (using a hypercall).

Petr Tesarik (2):
Add a kexec_crash_loaded() function
Allow kdump with crash_kexec_post_notifiers
arch/x86/xen/e
If a crash kernel is loaded, do not crash the running domain. This is
needed if the kernel is loaded with crash_kexec_post_notifiers, because
panic notifiers are run before __crash_kexec() in that case, and this
Xen hook prevents its being called later.

Let's start a discussion on the kexec mailing list (in Cc) to clarify
what should be done by the old kernel and what should be done by the
purgatory code.
