ramdisk is at
RAMDISK: [mem 0x27608000-0x2fafbfff]
and current kernel default set 1G to kernel mapping. so it happens to
work with your patchset.
please find one sytem with 4G or more to test it.
and you may need to rebase your patches on top of my for-x86-boot
branch with working
#PF handler set page table patch.

for-x86-boot
Thanks
