move kernel virtual address space to upper addresses
* i386/i386/vm_param.h: adjust constants to the new kernel map
- the boothdr.S code already sets up a temporary map to higher
addresses, so we can use INIT_VM_MIN_KERNEL_ADDRESS as in xen
- increase the kernel map size to accomodate for bigger structures
and more memory
- adjust kernel max address and directmap limit
* i386/i386at/biosmem.c: enable directmap check also on x86_64
* i386/include/mach/i386/vm_param.h: increase user virtual memory
limit as it's not conflicting with the kernel's anymore
* i386/intel/pmap.h: adjust lin2pdenum_cont() and INTEL_PTE_PFN to the
new kernel map
* x86_64/Makefrag.am: change KERNEL_MAP_BASE to be above 4G, and
according to mcmodel=kernel. This will allow to use the full memory
address space.
