The patch titled
Subject: kexec: allow kdump with crash_kexec_post_notifiers
has been removed from the -mm tree. Its filename was
allow-kdump-with-crash_kexec_post_notifiers.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Petr Tesarik <ptesarik@xxxxxxxx>
Subject: kexec: allow kdump with crash_kexec_post_notifiers
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.
[akpm@xxxxxxxxxxxxxxxxxxxx: build fix: unconditionally include kexec.h]
