With the Bluetooth 3.0 specification and the introduction of alternate
MAC/PHY (AMP) support, it is required to differentiate between primary
BR/EDR controllers and 802.11 AMP controllers. So introduce a special
type inside HCI device for differentiation.
For now all AMP controllers will be treated as raw devices until an
AMP manager has been implemented.

The GT-64111 PCI host bridge has no address translation mechanism, so
it can't generate legacy port accesses. This quirk fixes legacy device
port resources to contain the bus addresses actually generated by the
GT-64111.
I think this is the approach Ben Herrenschmidt suggested long ago:
http://marc.info/?l=linux-kernel&m=119733290624544&w=2
This allows us to remove the IORESOURCE_PCI_FIXED hack from
pcibios_fixup_device_resources(), which converts bus addresses to CPU
addresses. IORESOURCE_PCI_FIXED denotes resources that can't be moved;
it has nothing to do with converting bus to CPU addresses.

On Alchemy the PCMCIA area lies at the end of the chips 36bit system bus
area. Currently, addresses at the far end of the 32bit area are assumed
to belong to the PCMCIA area and fixed up to the real 36bit address before
being passed to ioremap().
A previous commit enabled 64 bit physical size for the resource datatype on
Alchemy and this allows to use the correct 36bit addresses when registering
the PCMCIA sockets.
This patch removes the 32-to-36bit address fixup and registers the Alchemy
demo board pcmcia socket with the correct 36bit physical addresses.
Tested on DB1200, with a CF card (ide-cs driver) and a 3c589 PCMCIA ethernet
card.

Because the VIA SuperIO chip only decodes 24 bits of address space but port
address space currently being configured as 32MB there is the theoretical
possibility of aliases within the I/O port address range.
The complicated solution is to reserve all address range that potencially
could cause such aliases. But with the PCI spec limiting port allocations
for devices to a maximum of 256 bytes 16MB of port address space already is
way more than one would ever expect to be used so we just reduce the port
space to 16MB.

This is just a test program for raw_spinlocks. The main reason I
wrote it is to validate my spinlock changes that I sent in a previous
patch.
To use it enable CONFIG_DEBUG_FS and CONFIG_SPINLOCK_TEST then at run
time do:
# mount -t debugfs none /sys/kernel/debug/
# cat /sys/kernel/debug/mips/spin_single
# cat /sys/kernel/debug/mips/spin_multi
On my 600MHz octeon cn5860 (16 CPUs) I get
spin_single spin_multi
base 106885 247941
spinlock_patch 75194 219465
This shows that for uncontended locks the spinlock patch gives 41%
improvement and for contended locks 12% improvement (1/time).

The current locking mechanism uses a ll/sc sequence to release a
spinlock. This is slower than a wmb() followed by a store to unlock.
The branching forward to .subsection 2 on sc failure slows down the
contended case. So we get rid of that part too.
Since we are now working on naturally aligned u16 values, we can get
rid of a masking operation as the LHU already does the right thing.
The ANDI are reversed for better scheduling on multi-issue CPUs
On a 12 CPU 750MHz Octeon cn5750 this patch improves ipv4 UDP packet
forwarding rates from 3.58*10^6 PPS to 3.99*10^6 PPS, or about 11%.

If we wait for the once-per-second cleanup to free transmit SKBs,
sockets with small transmit buffer sizes might spend most of their
time blocked waiting for the cleanup.
Normally we do a cleanup for each transmitted packet. We add a
watchdog type timer so that we also schedule a timeout for 150uS after
a packet is transmitted. The watchdog is reset for each transmitted
packet, so for high packet rates, it never expires. At these high
rates, the cleanups are done for each packet so the extra watchdog
initiated cleanups are neither needed nor triggered.
