Drivers have no business looking at the task list and thus using this
lock. The only possibly modular users left are:
arch/ia64/kernel/mca.c
drivers/edac/edac_mc.c
fs/binfmt_elf.c
which I'll send out fixes for soon.

+What: remove EXPORT_SYMBOL(tasklist_lock)
+When: August 2006
+Files: kernel/fork.c
+Why: tasklist_lock protects the kernel internal task list. Modules have
+ no business looking at it, and all instances in drivers have been due
+ to use of too-lowlevel APIs. Having this symbol exported prevents
+ moving to more scalable locking schemes for the task list.
