This patch was never applied after GSoC 2012. Rebase the parts that
still apply so we can close the ticket.

Fixes #9490.

Style fix.

Check if gARMPagingMethod is null

in arch_vm_translation_map_is_kernel_page_accessible. Fix borrowed from x86
(commit 428b9e758c30a95154f5ad0d974894ef9ae133d6).

Fixes #11107.

Remove phys_addr_range, just use addr_range for both virtual and physical address ranges (as requested by Ingo).

Changed addr_range to use uint64.

I've tested this change on x86, causing no issues. I've checked over the code
for all other platforms and made the necessary changes and to the best of my
knowledge they should also still work, but I haven't actually built and
tested them. Once I've completed the kernel_args changes the other platforms
will need testing.

kernel arm: Quick style cleanup; No functional change

* Quiet down VM debug output, so we can easily find errors ;)

* ARM: Major VM work
- This is mostly a copy of the x86 32bit paging method and infrastructure, this was copied for two reasons:
1) It is the most complete VM arch
2) The first ARM PAE patches have landed on alkml, so we will have to deal with it in the future as well,
and this infrastructure has proven to be ready ;)
- No protection features, or dirty/accessed tracking yet
- Lots of #if 0

but....

It boots all the way up to init_modules() now, and then dies because of a lack of (ARM) ELF relocation implementation!

Since at this point the VM can be fully initialised, I'm going to focus on CPU exceptions next, so we can get KDL to trigger
when it happens, and I can actually debug from there ;)

* First run through the kernel's private parts to use phys_{addr,size}_t
where appropriate.
* Typedef'ed page_num_t to phys_addr_t and used it in more places in
vm_page.{h,cpp}.

* Renamed vm_cache.h/vm_address_space.h to VMCache.h/VMAddressSpace.

- stubbed out many arch kernel functions (borrowed from other archs),
- partially implement ELF relocations code, enough to load the kernel,
- move uart.c to kernel sources and use the same one for the loader,
- default implementation for gensyscalls,
- assembler code functions for interrupt masking (enable/disable/restore/query).
