[PATCH v2 0/2] Make it possible to reserve memory on 64bit platform

[Wesley Zhao]

I was trying to reserve some memory to save logs incase that Android panic or hang and then
I can read the logs from QNX side from the memory reserved before on the Qualcomm 8155 hypervisor platform,
and I find the "reserve=" parameter only support 32bit,so I made some change and send these patches.

testcase:
	I test on the qemu with some cmdline like[qemu-system-x86_64 -kernel linux-next/arch/x86_64/boot/bzImage
	-hda ubuntu-system.ext4 -append "root=/dev/sda init=/bin/bash console=ttyS0 reserve=0x180000000,0x123456"
	-nographic]	and check the /proc/iomem with 180000000-180123455 : reserved.
	And some other tests with the get_option with the parameter(-12345678) and so on
