Side note: in general I don't mind making compat.h a bit more 
generic (at all), but is_ia32_task() is really a generic x86 
specific check that we can move to processor.h cleanly.

Some other effort should make compat.h bitness agnostic - 
uprobes doesn't actually make use of the compat types and 
facilities there, and it resulted in a nonsensical change like 
making the alloc function generic ...

Thanks,
