How update happen for pt_regs

Jan. 21, 2014

      Dear All,

I want to dump ARM registers, show_regs(regs) in spin_dump() function.

But show_regs get called only from traps or fault code. Any idea how
we can do in normal scenario ?

Also I check code pt_regs got updated in  entry-armv.S, If any body
have more idea how it is done.

Thanks
