Jeremy's brk patches may break:
1. kexec load 64bit vmlinux on some ram that near the memory hole etc.
blindly to use ram after _end may have some problem
2. coreboot aka linux is using elf (by mkelfImage : vmlinux + initrd), initrd became one section after _end...
could cause initrd get overwrite... by extend _brk

But its no different from what i386 does now to allocate its initial pagetables. How does this not break now?
