Hi!


Is it possible to call a function that is somewere in the physical-address
space? So I'd like to jump to a certain physical address, execute the code
there and then return to my kernel module. 
I already tried to ioremap that address and cast the new address to a
funtion pointer and then call the function, but there where some page
faults.


Regards
