Hi all,
Today's linux-next merge of the memblock tree got a conflict in:
kernel/Kconfig.kexec
between commit:
48a1b2321d76 ("liveupdate: kho: move to kernel/liveupdate")
from the mm-nonmm-stable tree and commit:
ab65699f9add ("memblock: remove CONFIG_MEMBLOCK_KHO_SCRATCH option")
from the memblock tree.
I fixed it up (I used the former version of the above file and then
added the following merge resolution patch) and can carry the fix as
necessary. This is now fixed as far as linux-next is concerned, but any
non trivial conflicts should be mentioned to your upstream maintainer
when your tree is submitted for merging. You may also want to consider
cooperating with the maintainer of the conflicting tree to minimise any
particularly complex conflicts.

It appears that the above memblock tree commit has been removed from
the memblock tree, so this resolution is not longer needed.
