Subject: [PATCH v5 0/2] x86/boot: Use efi_setup_data for searching RSDP on kexec-ed kernel

In this series, patch 2/2 has dependency on patch 1/1, otherwise
it may cause system to reset to firmware on some machines.

The patch 2/2 is the version Boris organized:

http://lkml.kernel.org/r/20190422092804.15534-1-kasong@redhat.com

Dave Young confirmed this patchset passed test on his t420 laptop, where
the system resetting issue caused by patch 2/2 was found.
