This dies with quilt 0.44, thusly:

Applying patch procfs-provide-stack-information-for-threads-v08.patch
can't find file to patch at input line 20
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|From: Stefani Seibold <stefani@seibold.net>
|
|A patch to give a better overview of the userland application stack usage,
|especially for embedded linux.
|
|Currently you are only able to dump the main process/thread stack usage
|which is showed in /proc/pid/status by the "VmStk" Value.  But you get no
|information about the consumed stack memory of the the threads.
|
|There is an enhancement in the /proc/<pid>/{task/*,}/*maps and which marks
|the vm mapping where the thread stack pointer reside with "[thread stack
|xxxxxxxx]".  xxxxxxxx is the maximum size of stack.  This is a value
|information, because libpthread doesn't set the start of the stack to the
|top of the mapped area, depending of the pthread usage.
|
|A sample output of /proc/<pid>/task/<tid>/maps looks like:
|
|08048000-08049000 r-xp 00000000 03:00 8312       /opt/z
|08049000-0804a000 rw-p 00001000 03:00 8312       /opt/z
--------------------------
No file to patch.  Skipping patch.
patch: **** /tmp/poPjWncl : No such file or directory
Patch procfs-provide-stack-information-for-threads-v08.patch does not apply (enforce with -f)

Yowza.  Not sure what makes it think there's an issue at line 20, looks to
*me* like the actual patch starts on line 77.
