[linux-audio-user] problems patching 2.6.12 with latest rt_preempt

[Shayne O'Connor]

i'm having problems patching vanilla 2.6.12 with ingo molnar's latest 
rt_preempt ...

[mrmachine at localhost linux-2.6.12]$ patch -p1 < 
../realtime-preempt-2.6.12-final-V0.7.50-12
missing header for unified diff at line 5 of patch
can't find file to patch at input line 5
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|Index: Makefile
|===================================================================
|--- Makefile.orig
|+++ Makefile
--------------------------
File to patch:

i've successfully patched all the Release Candidates leading up to 
2.6.12, so i don't know what the stumbling block is here ... any ideas?
