Robin Randhawa 1e10cac3e1 aarch64: Increase storage for FP context to consider AArch64's needs
Brute-forcing this at present. Would be better to wrap this
conditionally for the architecture.

Robin Randhawa 65448c2d48 aarch64: context: memory: Grant::map_inactive: Bugfix
When mapping one (from) virtual address range to another (to) virtual
address range, be mindful of which mapper type to use for each range.

Before this, the same mapper type was used for both ranges. This meant
that if from and to were different (as in not both kernel virtual
addresses or user virtual addresses) then it would appear that either
from or to was not mapped previously and the kernel would panic.

At present these are done 'wholesale' without any regard for x86_64.
That needs to change eventually.

Robin Randhawa 67d72532a9 aarch64: usermode: Remove tpidr_el0 manipulation
Was using the incorrect USER_TLS_OFFSET instead of USER_TCB_OFFSET. In
any case, this is better done in process::clone.
