[PATCH] deprecate the tasklist_lock export

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.

What: mount/umount uevents
When: February 2007
Why: These events are not correct, and do not properly let userspace know
