From: Minfei Huang <mnfhuang@xxxxxxxxx>
Subject: kexec: Remove obsolete flag 'in_crash_kexec'
Previously, UV NMI used 'in_crash_kexec' flag to be sure that we are in
kdump kernel or not in commit 5edd19af18a36a4e ("x86, UV: Make kdump avoid
stack dumps"). But this flags is removed in commit 9c48f1c629ecfa114850c0
("x86, nmi: Wire up NMI handlers to new routines").
Since it isn't used any more, remove it.
