-     [PATCH] Avoid false-positive mem_section validation with vmlinux
-     
-     Currently get_mem_section() validates if SYMBOL(mem_section) is the address
-     of the mem_section array first.  But there was a report that the first
-     validation wrongly returned TRUE with -x vmlinux and SPARSEMEM_EXTREME
-     (4.15+) on s390x.  This leads to crash failing statup with the following
-     seek error:
-     
-       crash: seek error: kernel virtual address: 67fffc2800  type: "memory section root table"
-     
-     Skip the first validation when satisfying the conditions.

+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.
