Add two new sysfs entries per cpu: idle_count and idle_time.
idle_count contains the number of times a cpu went into idle state.
idle_time contains the time a cpu spent in idle state in microseconds.
This can be used e.g. by powertop to tell how often idle state is
entered and left.
# cat /sys/devices/system/cpu/cpu0/idle_count
504
# cat /sys/devices/system/cpu/cpu0/idle_time

A few trivial Makefile cleanups
- dependencipes in head.o was all wrong - deleted
- CMODEL_CFLAG was not used anywhere
- NEW_GCC was then not used outside sparc64/Makefe - do not export it
- FIXME seems not appropriate - all other put oprofile in drivers-y too
- No reason to do -I. (and it still builds)

This will allow us to decrease the cost of the MSI queue dispatch.

I get the following warning from a powerpc allyesconfig of current
mainline:
drivers/net/niu.c: In function 'niu_size_rbr':
drivers/net/niu.c:3113: warning: large integer implicitly truncated to unsigned type
PAGE_SIZE in this case is 64KB, so I don't quite get why gcc can't
tell that the line in question will never be reached.
I suggest the following instead, but I can unfortunately not do
anything but build test it.
Also, the driver does some other checks to make sure that PAGE_SIZE is
a power of two (BUILD_BUG_ON() in niu_init()), doesn't seem like that
could ever be untrue? Or are there really archs with non-power-of-two
PAGE_SIZE?

The calculation in SKB_WITH_OVERHEAD is incorrect in that it can cause
an overflow across a page boundary which is what it's meant to prevent.
In particular, the header length (X) should not be lumped together with
skb_shared_info. The latter needs to be aligned properly while the header
has no choice but to sit in front of wherever the payload is.
Therefore the correct calculation is to take away the aligned size of
skb_shared_info, and then subtract the header length. The resulting
quantity L satisfies the following inequality:
SKB_DATA_ALIGN(L + X) + sizeof(struct skb_shared_info) <= PAGE_SIZE
This is the quantity used by alloc_skb to do the actual allocation.

The Bluetooth HCI commands are divided into logical OGF groups for
easier identification of their purposes. While this still makes sense
for the written specification, its makes the code only more complex
and harder to read. So instead of using separate OGF and OCF values
to identify the commands, use a common 16-bit opcode that combines
both values. As a side effect this also reduces the complexity of
OGF and OCF calculations during command header parsing.
