After 84c91b7ae merged to v3.17 kernel, hibernate code checks the e280 regions
should not be changed when doing hibernate resume. Without your patch 8,
the hibernate resume checking will randomly fail on the machines that reserved
setup_data in e820 regions.

Could you please consider to put "[PATCH v2 08/15] x86: Kill E820_RESERVED_KERN"
to v4.0 kernel?


Thanks a lot!
Joey Lee
