Ard Biesheuvel 67d762e716 target/arm: Avoid target_ulong for physical address lookups 
target_ulong is typedef'ed as a 32-bit integer when building the
qemu-system-arm target, and this is smaller than the size of an
intermediate physical address when LPAE is being used.

Given that Linux may place leaf level user page tables in high memory
when built for LPAE, the kernel will crash with an external abort as
soon as it enters user space when running with more than ~3 GiB of
system RAM.

So replace target_ulong with vaddr in places where it may carry an
address value that is not representable in 32 bits.
