Subject: [PATCH] kdump: fix an error that can not parse the e820 reserved
 region

When kexec-tools load the kernel and initramfs for kdump, kexec-tools will
read /proc/iomem and recreate the e820 ranges for kdump kernel. But it fails
to parse the e820 reserved region, because the memcmp() is case sensitive
when comparing the string. In fact, it may be "Reserved" or "reserved" in
the /proc/iomem, so we have to fix these cases.
