Hi Ohad,
the architecture I'm working on, Infineon's Tricore microcontroller, has 16
general purpose data registers and 16 general purpose address registers (pc,
psw and so on are kept in special core registers). So I guess I have enough
registers to sacrifice one for holding the "current" value.

Then there must be a function (or an instruction in a function), which
stores the pointer to the current task_struct in the register r2, right? Do
you know, where that function/instruction can be found in kernel code, so I
can modify it for my register set?
Thanks for your help,
Paul
