The current Macro

["Paul Duplys" <kernel_newbie@xxxxxx>]

Hi all!

As I already mentioned in my earlier emails, I am working on a linux port
for a new architecture. 

I'm now trying to define the "current" macro. I read that most architectures
keep a pointer to the thread_info instance in some processor register, so I
thought it will be perhaps ok if I'll do it too. 

Well, that's actually not a problem, since I can get the content of any
register using inline assembly instructions. But which register should I
use? 

I mean, where in the kernel is a macro or a function which stores the
pointer to thread_info in some register? In other words, how do I find out
which register is actually used by the kernel for storing that pointer?

I also want to thank you all for your answers to my earlier emails. You have
really helped me a lot and I'm glad, that I joined this mailing list!

Regards, Paul
