perf_event wants a separate event for alignment and emulation faults,
so create another emulation event. This will make it easy to hook in

In continuous sampling mode we want the SDAR to update. While we can
select between dcache misses and erat misses, a decent default is to

I know this is probably a really dumb question, but a wise man once said that
the only stupid question is the one that is not asked.
So, I have written a flash driver in VxWorks that simply addresses the flash
directly and handles all the hardware accesses just fine. I am porting that to

Hello, I am using the mpt2sas driver on the canyonlands / 460EX board.
I've already found and fixed one problem, but can't get past the
unhandled IRQ.
The first problem I noticed is that the physical address is read into a
32 bit variable, but the 460ex has a 36 bit bus so the ioremap would

Romen,
A driver for micrel phy exists in /drivers/net/phy/micrel.c. in 2.6.30.
You just need to add the structure with your phy information .
If you are using older kernel you may want to copy it.

Hmmm, so if the issue I see is related to what you see then setting mtu
to 4KB may clear it otherwise I have a either a potential race condition
freeing skb's or ultimately the protocol stack is not freeing the
correct buffer...
Thanks Jonathan.
