[PATCH 9/20] x86_64: 64bit PIC SMP trampoline

2006-11-17 Thread Vivek Goyal
This modifies the SMP trampoline and all of the associated code so it can jump to a 64bit kernel loaded at an arbitrary address. The dependencies on having an idenetity mapped page in the kernel page tables for SMP bootup have all been removed. In addition the trampoline has been modified to ve
