Ingo,
Here's a little clean up patch.
Randy Dunlap should be happy that I changed my script to combine the
header and patch in one email if I only have a single patch.

ftrace: use init_struct_pid as swapper pid
Impact: clean up
Using (struct pid *)-1 as the pointer for ftrace_swapper_pid is
a little confusing for others. This patch uses the address of the
actual init pid structure instead. This change is only for
clarity. It does not affect the code itself. Hopefully soon the
swapper tasks will all have their own pid structure and then
we can clean up the code a bit more.
