Hi All
Im running Linux 2.6.32.14 on an embedded MPC4858.
One of the Application (CLI) must reciece a UDP broadcast packet.
The problem is that I only receive packets broadcast from within the
same subnet (192.168.0.x) even though the broadcast app sends the
broadcast to 255.255.255.255.

The 64-bit Book-E parts (to date) dont utilize the 'server' class
perfmon. So building or depending on it makes no sense (and does break
FSL Book-E 64-bit support). Move the selection of PPC_HAVE_PMU_SUPPORT
to be based on PPC_BOOK3S_64.
Based on a patch from Scott Wood.

The problem was that "reverse-path filtering" was enabled. after
disabling reverse-path filtering I could receive broadcasts as
expected.
As a side note - interface does not need to be in promiscuous mode

Hi Peter,
Surely this isn't the first multi-node P7 to boot a kernel with this
patch? If my git foo is any good it hit -next on 23rd of May.
I guess I'm asking is, do smaller P7 machines boot? And if so, is
there any difference except size?
How many nodes does the thing have anyway, 28?
Old code didn't check the proper registers for the 460sx and so the link check
would always fail. This changes the link check to use the config space reg and
adds the definition for the register. Also changes the vc0 to a pll check.
