Make sure Dwarf_Ops don't have garbage
We synthesize a Dwarf_Op in a couple of places, but we were only setting
the fields we care about, ".atom" and ".number". The garbage in
".number2" would survive into "DWARF expression:" comment in loc2c,
which made it look unique and subverted caching.
Now we memset-0 the Dwarf_Op before proceeding.

sk_stream_wait_memory spelling fixes
commit b3e1fb913452cd1304ab9b0eae0008215fcd437e

Update bkl examples with newer syntax
* testsuite/systemtap.examples/locks/bkl.stp: Use '!' to alternate
kernel probepoints between lock_kernel and _lock_kernel (and unlock).
* testsuite/systemtap.examples/locks/bkl_stats.stp: Ditto, and use
@entry to get timestamps.

Use actual bytes read/written for iotop
Probe on .return, so we know how many bytes the vfs actually handled.
commit 9d3187ef9327b14cdcb975b4f8555fc2aa6410c6
Author: Josh Stone <jistone@redhat.com>
Date: Tue Jul 20 12:32:47 2010 -0700
Remove explicit entry probes from iotime example
For the use of syscall.open/read/write, use .return to do all the work.
This uses @entry to collect timestamps and implicit saving for other
$vars.
Note that $return is used for byte counts instead of the entry $count,
because we should care more about the actual work performed.

Add para-callgraph-verbose example
It's like para-callgraph, except using $$parms$$. The output can get
VERY big, so you probably want to dump it into a file for offline
browsing...
