2012-03-23Fix boot with big values of _startSamuel Thibault
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.
