Grub is not able to map us at high addresses. We can however make it load us at
low addresses (through the linker script mapping), then use segmentation to move
ourselves to high addresses, and switch to C which uses high addresses
(through _START definition).
* i386/ldscript: Force mapping kernel at 0x100000, regardless of the value
of _START.

The former is the initial value set by the bootloader. It may not be the
same as what Mach will set up.

0xffffffff.

When _start is not close to 0, just using init_alloc_aligned() is not enough
to know how much should be duplicated between linear and virtual mappings.
Just mapping everything that can be is not very costly and should just work
when it can work.
* i386/i386at/model_dep.c (i386at_init) [VM_MIN_KERNEL_ADDRESS !=
LINEAR_MIN_KERNEL_ADDRESS]: Extend `nb_direct' to VM_MIN_KERNEL_ADDRESS -
LINEAR_MIN_KERNEL_ADDRESS.
|

* i386/i386/i386asm.sym (PFN_LIST): Enclose in #ifdef MACH_XEN. Thanks
to Samuel Thibault for the suggestion.
