 0004-x86-64-Convert-exception-stacks-to-per-cpu.patch
 0005-x86-64-Move-cpu-number-from-PDA-to-per-cpu-and-cons.patch
 0006-x86-64-Move-current-task-from-PDA-to-per-cpu-and-co.patch
 0007-x86-64-Move-kernelstack-from-PDA-to-per-cpu.patch
 0008-x86-64-Move-oldrsp-from-PDA-to-per-cpu.patch
 0009-x86-64-Move-irqcount-from-PDA-to-per-cpu.patch
 0010-x86-64-Move-nodenumber-from-PDA-to-per-cpu.patch
 0011-x86-64-Move-isidle-from-PDA-to-per-cpu.patch
 0012-x86-64-Use-absolute-displacements-for-per-cpu-acces.patch

with the following changes

* Add underbars between words in variable names (e.g. irqstack ->
  irq_stack)

* Drop irq_stack_ptr early initialization on SMP from 0003.

* Change DECLARE/DEFINE_PER_CPU(char, irq_stack[IRQ_STACK_SIZE]) to
  DECLARE/DEFINE_PER_CPU(char[IRQ_STACK_SIZE], irq_stack) in 0003.
         
* Move cpu_number definition out of CONFIG_HAVE_SETUP_PER_CPU_AREA
  in 0005.

* Remove now unused stack_thread_info() in 0007.
