Subject: [PATCH] ppc64: remove rma_top limit
Restricting kexec tool to allocate hole for kexec segments below 768MB
may not be relavent now since first memory block size can be 1024MB and
more.
Removing rma_top restriction will give more space to find holes for
kexec segments and existing in-place checks make sure that kexec segment
allocation doesn't cross the first memory block because every kexec segment
has to be within first memory block for kdump kernel to boot properly.

From: Sourabh Jain <sourabhjain@linux.ibm.com>

Subject: [PATCH 1/6] ppc64: add --reuse-cmdline parameter support
An option to copy the command line arguments from running kernel
to kexec'd kernel. This option works for both kexec and kdump.
In case --append=<args> or --command-line=<args> is provided along
with --reuse-cmdline parameter then args listed against append and
command-line parameter will be combined with command line argument
from running kernel.

kernel does not understand the supplied image fall back to the old KEXEC_LOAD
interface.
-There is no one single interface that always works.
+There is no one single interface that always works, so this is the default.
KEXEC_FILE_LOAD is required on systems that use locked-down secure boot to
verify the kernel signature. KEXEC_LOAD may be also disabled in the kernel
