* Patch by Yuli Barcohen, 4 Mar 2004:
Fix problems with GCC 3.3.x which changed handling of global variables explicitly initialized to zero (now in .bss instead of .data as before). * Patch by Leon Kukovec, 02 Mar 2004: add strswab() to fix IDE LBA capacity, firmware and model numbers on little endian machines * Patch by Masami Komiya, 02 Mar 2004: - Remove get_ticks() from NFS code - Add verification of RPC transaction ID * Patch by Pierre Aubert, 02 Mar 2004: cleanup for IDE and USB drivers for MPC5200
