Hi ben
Now that many things are becoming clear let me sum up my understanding until
this point. Do correct it if there are mistakes.
1. Linux page table structure (PGD, PUD, PMD and PTE) is directly used in
case of architecture that lend themselves to such a tree structure for
maintaining virtua

External/Decrement exceptions have lower priority than the Debug Exception.
So, we don't have to disable the External interrupts before a single step.
However, on BookE, Critical Input Exception(CE) has higher priority tha

gcc (rightfully) complains that we are accessing beyond the
end of the fpr array (we do, to access the fpscr).
The only sane thing to do (whether anything in that code can be
called remotely sane is debatable) is to special case fpscr and
handle it as a separate stat

Hi Grant and others,
I have a question regarding number of cells in ranges property

Linux pci/pcie powerpc DTSes contain 7 cells (xpedite5370.dts, sequoia.dts, etc)
but also 6 cells format too (mpc832x_mds.dts)
Here is shown 6 cells ranges format and describe
