Current SHPCHP driver shows device number of slots in info messages,
but it is useless and should be replaced with slot name.
This patch replaces the device number shown in the info messages with
the slot name.

Current SHPCHP driver doesn't take care of RsvdP/RsvdZ[*] bits in

[*] RsvdP and RsvdZ are defined in SHPC spec as follows:
RsvdP - Reserved and Preserved. Register bits of this type are
reserved for future use as R/W bits. The value read is
undefined. Writes are ignored. Software must follow These rules
when accessing RsvdP bits:
- Software must ignore RsvdP bits when testing values read
from these registers.
- Software must not depend on RsvdP bit's ability to retain
information when written
- Software must always write back the value read in the RsvdP
bits when writing one of these registers.
RsvdZ - Reserved and Zero. Register bits of this type are reserved
for future use as R/WC bits. The value read is undefined. Writes
are ignored. Software must follow these rules when accessing RsvdZ
bits:
- Software must ignore RsvdZ bits when testing values read
from these registers.
- Software must not depends on a RsvdZ bit's ability to retain
information when written.
- Software must always write 0 to RsvdZ bits when writing one
of these register.

o hotplug slots add
When the hot-added PCI device is p2p bridge, acpiphp calls
find_p2p_bridge() to add hotplug slots.
o hotplug slots remove
When the hot-removing PCI device is p2p bridge, acpiphp
calls cleanup_p2p_bridge() to remove hotplug slots.
o notify handler exchange
When the p2p bridge is added, acpiphp changes the notify
hanlder.
If no bridge device is inserted into the hotpluggable PCI
slot, acpiphp installs the notify handler for function.
After the p2p bridge hot-add, acpiphp has to install the
notify handler for bridge. Because, the role of the
handlers are not same. The hot-remove case is ditto.

Patch from Andrew Victor
This patch includes a number of updates to the AT91RM9200 serial driver.
Changes include:
1. Conversion to a platform_driver. [Ivan Kokshaysky]
2. Replaced all references to AT91RM9200 with AT91. This driver can now
also be used for the AT91SAM9216.
3. Allow TIOCM_LOOP to configure local loopback mode.
4. Cleaned up the 'read_status_mask' usage and interrupt handler code.
[Chip Coldwell]
5. Suspend/resume support. [David Brownell]
There are a few 'unused variable' warning when compiling this - I
removed the new DMA support to keep this first patch simpler.

The current stack treats NETIF_F_HW_CSUM and NETIF_F_NO_CSUM
identically so we test for them in quite a few places. For the sake
of brevity, I'm adding the macro NETIF_F_GEN_CSUM for these two. We
also test the disjunct of NETIF_F_IP_CSUM and the other two in various
places, for that purpose I've added NETIF_F_ALL_CSUM.

Herbert Xu pointed out that it is unsafe to call netif_tx_disable()
from LLTX drivers because it uses dev->xmit_lock to synchronize
whereas LLTX drivers use private locks.
Convert tg3 to non-LLTX to fix this issue. tg3 is a lockless driver
where hard_start_xmit and tx completion handling can run concurrently
under normal conditions. A tx_lock is only needed to prevent
netif_stop_queue and netif_wake_queue race condtions when the queue
is full.
So whether we use LLTX or non-LLTX, it makes practically no
difference.

Remove tx_lock where it is unnecessary. tg3 runs lockless and so it
requires interrupts to be disabled and sync'ed, netif_queue and NAPI
poll to be stopped before the device can be reconfigured. After
stopping everything, it is no longer necessary to get the tx_lock.
