The patch titled
Subject: kexec: set KEXEC_TYPE_CRASH before sanity_check_segment_list()
has been removed from the -mm tree. Its filename was
kexec-set-kexec_type_crash-before-sanity_check_segment_list.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Xunlei Pang <xlpang@xxxxxxxxxx>
Subject: kexec: set KEXEC_TYPE_CRASH before sanity_check_segment_list()
sanity_check_segment_list() checks KEXEC_TYPE_CRASH flag to ensure all the
segments of the loaded crash kernel are within the kernel crash resource
limits, so set the flag beforehand.
