Dear,
I am trying to write embedded linux kernel module to get the value of BCSR
registers for ppc460ex .
I am a newbie. How I access the BCSR register.
Thanks,

Hi,
I have no comments about coding and architecture. It looks fine.
Only have a query about its use case..
Any application intended to use message interrupt requires to
know
reg_num because of struct mpic_msgr* mpic_msgr_get(unsigned int
reg_num) API
When we take an interrupt or exception from kernel mode and the stack
pointer is obviously not a kernel address (i.e. the top bit is 0), we
switch to an emergency stack, save register values and panic. However,
on 64-bit server machines, we don't actually save the values of r9 - r13
at the time
