vm: optimise page array size and initialisation.
...
* the page array now only extends up to the last non-reserved memory frame.
* rather than memset'ing the whole array to zero, we only initialise p_flags
for each page in vm_page_array_init, and then leave it to group_pages_into_block
to initialise the other parts of vm_page_t.

memblock: mark bytes preceding an aligned allocation as reserved.
...
this prevents tiny holes of free memory appearing between
blocks of aligned allocations.

vm: explicitly initialise kmalloc in vm_bootstrap
...
if kmalloc is called with count=N before vm_bootstrap is finished,
the request will be fulfilled using memblock_alloc.
if N is a power of 2, the returned pointer will be aligned to
an N-byte boundary.

vm: add alignment parameter to cache allocator
...
caches with object size N, where N is a power of two, will naturally
align their objects on N-byte boundaries.
all other caches will align to an 8-byte boundary by default.
