* introduces central memory map for core/kernel * on 32-bit platforms the kernel/core starts at 0x80000000 * on 64-bit platforms the kernel/core starts at 0xffffffc000000000 * mark kernel/core mappings as global ones (tagged TLB) * move the exception vector to begin of core's binary, thereby bootstrap knows from where to map it appropriately * do not map boot modules into core anymore * constrain core's virtual heap memory area * differentiate in between user's and core's main thread's UTCB, which now resides inside the kernel segment Ref #2091
