85b07cd1aa [PATCH] m68k: compile fix - hardirq checks were in wrong place 
move the sanity check for NR_IRQS being no more than 1<<HARDIRQ_BITS from
asm-m68k/hardirq.h to asm-m68k/irq.h; needed since NR_IRQS is not necessary
know at the points of inclusion of asm/hardirq.h due to the rather ugly header
dependencies on m68k.  Fix is by far simpler than trying to massage those
dependencies...

ab03591db1 [PATCH] ia64: task_thread_info() 
on ia64 thread_info is at the constant offset from task_struct and stack
is embedded into the same beast.  Set __HAVE_THREAD_FUNCTIONS, made
task_thread_info() just add a constant.

9fc658763b [PATCH] missing helper - task_stack_page() 
Patchset annotates arch/* uses of ->thread_info.  Ones that really are about
access of thread_info of given process are simply switched to
task_thread_info(task); ones that deal with access to objects on stack are
switched to new helper - task_stack_page().  A _lot_ of the latter are
actually open-coded instances of "find where pt_regs are"; those are
consolidated into task_pt_regs(task) (many architectures actually have such
helper already).

Note that these annotations are not mandatory - any code not converted to
these helpers still works.  However, they clean up a lot of places and have
actually caught a number of bugs, so converting out of tree ports would be a
good idea...

As an example of breakage caught by that stuff, see i386 pt_regs mess - we
used to have it open-coded in a bunch of places and when back in April Stas
had fixed a bug in copy_thread(), the rest had been left out of sync.  That
required two followup patches (the latest - just before 2.6.15) _and_ still
had left /proc/*/stat eip field broken.  Try ps -eo eip on i386 and watch the
junk...

This patch:

new helper - task_stack_page(task).  Returns pointer to the memory object
containing task stack; usually thread_info of task sits in the beginning
of that object.
