Introduce ARM_VM_SECTION_CACHED and ARM_VM_PTE_CACHED to ensure we
are using the correct caching flags everywhere.

3ef93645b9 Use ARM_VM_SECTION_MASK to determine kernel base address 
To map kernel we use 1M sections therefore we should use
ARM_VM_SECTION_MASK to determine base address.

b9cb8251bc arm:make no assumptions about TRE and AFE 
The bootloader can leave the system control register
in at state that doesn't match our setup. make no assumptions
and configure TRE and AFE.

e6bac75a8b ARM:Rename ARM_BIG_PAGE to ARM_SECTION. 
The natural term to use when talking about MINIX big pages on ARM
is SECTION. A section is a level 1 page table entry pointing to
a 1MB area.

First round, some more optimizations are possible and should be
activated.

3bc6d7df06 impove memory accounting 
. the total amount of memory in the system didn't include the memory
	  used by the boot-time modules and some dynamic allocation by the
	  kernel at boot time (to map in VM). especially apparent on our
	  ARM board with 'only' 512MB of memory and a huge ramdisk.
	. also: *add* the VM loaded module to the freelist after it has
	  been allocated for & mapped in instead of cutting it *out* of the
	  freelist! so we get a few more MB free..

b1c4ba4ab6 ARM updates 
Due to the ABI we are using we have to use the earm architecture
moniker for the build system to behave correctly. This involves
then some headers to move around.

There is also a few related Makefile updates as well as minor
source code corrections.
