[Cbe-oss-dev] [PATCH] Fix for syscall names in libspe-1.2.0

Here goes a patch that fixes an inconsistency between the syscall  
"names" defined
in libspe (include/sys/spe.h) and those defined by the kernel.  More  
details in
the patch header below.

Subject: Fix syscall names

The unistd.h header exposes symbolic names for syscall numbers.   
Those used
by the SPE's syscalls are prefixed with '__NR_spu', not '__NR_spe',  
but the
code here was using the latter to refer to them.  Therefore, it never  
a chance of using the values provided by the system and it felt back  
to the
ones hardcoded here.
