Hi Pratyush,
Yes it does, I fixed it upstream a few weeks ago:
commit a16324a2f05c0947a83e26a5de7c756de4603da9
Author: Dave Anderson <anderson at redhat.com>
Date: Thu Jul 6 16:19:41 2017 -0400
Fix for Linux 4.13-rc0 commit 7fd8329ba502ef76dd91db561c7aed696b2c7720
"x86/boot/64: Rename init_level4_pgt and early_level4_pgt". Without
the patch, the crash session fails during initialization with the
error message "crash: cannot resolve "init_level4_pgt".

As well as a fix for the SECTION_MAP_MASK change:
commit c24011916c6f70b3828ab522e3e6b0edb3c82677
Author: Dave Anderson <anderson at redhat.com>
Date: Wed Jul 19 10:06:49 2017 -0400
Fix for Linux 4.13-rc1 commit 2d070eab2e8270c8a84d480bb91e4f739315f03d
"mm: consider zone which is not fully populated to have holes".
Without the patch, SPARSEMEM page struct addresses are incorrectly
calculated because a new section state, and an associated flag bit,
has been added to the low bits of the mem_section.section_mem_map
address; the extra bit is erroneously passed back as part of the
section_mem_map and resultant page struct address, leading to
errors in commands such as "kmem -p", "kmem -s", "kmem -n", and any
other command that translates a physical address to its page struct
address.

I don't have support for 5-level paging as of yet.
Thanks,
Dave
