That's funny. parisc is the only one that was (sortof) wrong.

I just added an alias to parisc-linux so ECANCELLED is an alias
for ECANCELED:
	http://lists.parisc-linux.org/pipermail/parisc-linux-cvs/2005-April/035557.html

IIRC, parisc-linux defined ECANCELLED because that's what HPUX used.
And according to SuSv3, is an acceptable definition of the same error.
But Linux uses ECANCELED (with one "el").

In my spare time, I've been trying to build openib.org code on
parisc-linux. Last time I tried, I was running into the same
issue that Tom Duffy already pointed out about one of the 
new vm interfaces not being supported. I have to fix that
bit in parisc-linux port as well before I can move forward.

Please do not. Just fix the code to use ECANCELED since that's
what SuSv3 specifies and linux prefers:
include/asm-generic/errno.h:#define     ECANCELED       125     /* Operation Canceled */
