Subject: Oops in 2.6.27.39 vanilla with latest DTrace linux port - 
	dtrace-20091010.tar.bz2

Hi,

10/10/2009 09:50PM        814,999 dtrace-20091010.tar.bz2  ( I used
this tarrball )

I was able to use the DTrace perfectly well with 2.6.18 (x86_64). But
I had problems with the latest DTrace  port on 2.6.27.39.(x86_64).

I did the following changes inside the routine mem_set_writable() (
driver/dtrace_linux.c) and I could make it work with 2.6.27.39.

if (pmd_large(*pmd)) {
                pte = (pte_t *)pmd;
}
else {
                pte = pte_offset_kernel(pmd, addr);
 }

thanks
