* platform_allocate_elf_region() is removed, it is implemented in platform- independent code now (ELF*Class::AllocateRegion). For ELF64 it is now assumed that 64-bit addresses are mapped in the loader's 32-bit address space as (address - KERNEL_BASE_64BIT + KERNEL_BASE). * mapped_delta field from preloaded_*_image removed, now handled compile-time using the ELF*Class::Map method. * Also link the kernel with -z max-page-size=0x1000, removes the need for 2MB alignment on the data segment (not going to map the kernel with large pages for the time being).
