Hi Linus !
Here's another batch for before -rc2. The main highlight is the u64 conversion
to unsigned long long along with a bunch of patches fixing warnings due to this
conversion. There will be a few more, for example the PS3 code is still pretty
bad in this area, but that's about it.
The rest
This adds an init_dummy_netdev() function that gets a network device
structure (allocation and lifetime entirely under caller's control) and
initialize the minimum amount of fields so it can be used to schedule
NAPI polls without registering a full blown interface. This is to be
used by drivers
We just fix up the reference parameters as the others are dealt with by
arithmetic promotion rules and don't cause warnings.
This removes warnings like this:
arch/powerpc/platforms/ps3/interrupt.c:327: warning: passing argument 1 of
'lv1_construct_event_receive_port' from incompatible pointer
This fixes these compiler warning:
