that causes us to hang in the ksem code if we use more than one.

99f05559ed Don't return success when the target CPU is offline 
dt_status originally expected the behavior.

This fixes a segfault happens in dt_aggregate_go (a user of dt_status)
that depends on the behavior.

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).

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

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