2012-03-24Relocate kernel at bootupSamuel Thibault
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. * i386/i386at/boothdr.S (boot_entry): Set up initial segments to project the bootstrap linear space to high addresses.

2012-03-24Separate INIT_VM_MIN_KERNEL_ADDRESS from VM_MIN_KERNEL_ADDRESSSamuel Thibault

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.

2012-03-14Simplify i386at_initSamuel Thibault
* i386/i386at/model_dep.c (i386at_init): Do not copy linear into virtual kernel mapping when they are equal, and do not drop the former either. Use the function `i' variable.
