Extend machine addresses to 64bit for PAE
* i386/i386/pcb.c (switch_ktss): Use uint64_t for descriptor
type instead of unsigned long long.
* i386/i386/seg.h (fill_descriptor): Use uint64_t for descriptor
type instead of unsigned long long. Cast result of kv_to_ma()
into vm_offset_t before printing.
* i386/i386/xen.h (hyp_mmu_update_pte): Use pt_entry_t type
instead of unsigned long long, make pte parameter a pt_entry_t
too.
(hyp_mmu_update_pte): Compute pte address just using pt_entry_t
integers.
(hyp_high): New macro to fix 32bit right shifting.
(hyp_do_update_descriptor): Use pt_entry_t type for machine
address instead of unsigned long. Split it in 32bit parts. Use uint64_t
for descriptor type instead of unsigned long long.
(update_va_mapping): Use pt_entry_t type instead of unsigned
long long. Use hyp_high macro.
(hyp_invlpg): Use uint64_t for time type instead of unsigned
long long.
* i386/intel/pmap.c (pmap_bootstrap): Use ptetokv instead of
pte_to_pa + phystokv. Cast machine addresses into vm_offset_t
before printing.
(pmap_set_page_readwrite): Likewise.
(pmap_set_page_readonly): Likewise
(pmap_set_page_readonly_init): Likewise
(pmap_clear_bootstrap_pagetable): Likewise
(pmap_destroy): Likewise
(pmap_map_mfn): Use pt_entry_t type for machine addresses. Cast
machine addresses into vm_offset_t before printing.
* i386/intel/pmap.h [PAE] (INTEL_PTE_PFN): Set macro to
0xfffffffffffff000ULL.
* include/mach/xen.h [PAE] (pa_to_ma, ma_to_pa): Use pt_entry_t
type for machine addresses.
[!PAE] (pa_to_ma): Remove cast to vm_offset_t.
(mfn_to_kv): Use mfn_to_pfn + ptoa instead of ptoa + ma_to_pa.
* xen/xen.c (hyp_invalidate_pte): Cast machine addresses into
vm_offset_t before printing.
