     "Many great new features, fixes and optimizations, including:
       - Convert page table updates to use per-pagetable spinlocks which
         overall improves performance on SMP machines a lot, by Mikulas
       - Kernel debugger (KGDB) support, by Sven Schnelle
       - KPROBES support, by Sven Schnelle
       - Lots of TLB lock/flush improvements, by Dave Anglin
       - Drop DISCONTIGMEM and switch to SPARSEMEM
       - Added JUMP_LABEL, branch runtime-patching support
       - Lots of other small speedups and cleanups, e.g. for QEMU, stack
