The patch titled
x86_64-mm-remove-un-set_nmi_callback-and-reserve-release_lapic_nmi-functions-x86-fix
has been removed from the -mm tree. Its filename is
x86_64-mm-remove-un-set_nmi_callback-and-reserve-release_lapic_nmi-functions-x86-fix.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.

Subject: x86_64-mm-remove-un-set_nmi_callback-and-reserve-release_lapic_nmi-functions-x86-fix
From: Andrew Morton <akpm@xxxxxxxx>
Andi, will you please stop committing patches which break the x86 build? It's
a fairly popular architecture..
Vivek, I never know who maintains the kdump stuff. Some MAINTAINERS entries
would be nice.
Don, your patch consistently does
struct die_args *args = (struct die_args *)data;
which is consistently wrong. `data' is void* and does not need a cast - in
fact it's harmful.
And this patch may simply be wrong - crash_nmi_callback() wants the `cpu'
argument, but we've lost that, so I resorted to raw_smp_processor_id().
Calling that on the crashed CPU sounds like a bad idea.
