02cb0c6eaf Introduce a selector function to the vfs vnode iterator so that we don't 
need to vget() vnodes that we are not interested at, and optimize locking
a bit. Iterator changes reviewed by Hannken (thanks), the rest of the bugs
are mine.

23f76b6d00 An (un)privileged user can easily make the kernel dereference a NULL 
pointer.

The kernel allows 'data' to be NULL; it's the fs's responsibility to
ensure that it isn't NULL (if the fs actually needs data).

6713b766dd format is a pointer, so sizeof(format) is not a good length 
to pass to snprintf.  Try to calculate the correct length,
taking into account the amount of space already used.

1339b2cc13 Add MKCTF 
This variable separates CTF stuffs from MKDTRACE; we can build DTrace
solely without building and using them. This allows us to use DTrace
even if CTF stuffs have problems (actually they have now).

This variable would be merged into MKDTRACE eventually, once CTF stuffs
work correctly again.

4ae43925ec Exclude mvsoctmr_* functions from FBT targets 
Probing them doesn't work for DTrace/arm for some reason.

Anyway with this fix, DTrace/arm works on SHEEVAPLUG
as well as BEAGLEBONE.

609ba481a5 Implement DTrace FBT provider for ARM 
- Finding probable functions
- Replacing instructions
- Emulating instructions

It is tested only on ARMv7 CPUs yet, for example,
-m evbarm (-a earm) kernel=BEAGLEBONE.

48e9045322 Enable invop handler on module load 
It sets a fbt handler to dtrace_invop_jump_addr on module load,
which is used to call the dtrace probing function from the trap
handler.
