Becker-derived drivers often have the 'io_size' member in their chip
info struct, indicating the minimum required size of the I/O resource
(usually a PCI BAR). For many situations, this number is either
constant or irrelevant (due to pci_iomap convenience behavior).
This change removes the io_size invariant member, and replaces it with a
compile-time constant.
Drivers updated: fealnx, gt96100eth, winbond-840, yellowfin
Additionally,
- gt96100eth: unused 'drv_flags' removed from gt96100eth
- winbond-840: unused struct match_info removed
- winbond-840: mark pci_id_tbl[] const, __devinitdata

When in-kernel net drivers branched from Donald Becker's vanilla driver
set, in the days before BitKeeper and git, a driver changelog was
maintained in the driver source code. These days, the kernel's
changelog is far superior and much more accurate, so the in-driver
changelogs are removed.
Another relic of the Becker/kernel split was version numbering, using
"foo-LKx.y.z" notation, resulting in weird version numbers like
"1.17b-LK1.1.9". These drivers are for older hardware, and see few
changes these days, so the version numbers were all bumped to something
more simple.
Finally, in xircom_tulip_cb specifically, an additional cleanup removes
the always-enabled CARDBUS cpp macro.

- Remove in-source changelog, it's in the global kernel history.
- convert silly and useless version to useful one
- replace invariant pci_id_tbl[]::io_size uses with EPIC_TOTAL_SIZE
- remove now-unused io_size member from pci_id_tbl[]
- current kernel style prefers dev_printk() for the rare ethernet driver
messages that cannot print an 'eth%d' prefix.

With the new interrupt rework, an interrupt "host" map() callback can be
called after the interrupt is already active.
It's called again for an already mapped interrupt to allow changing the
trigger setup, and currently this is not guarded with a test of wether
the interrupt is requested or not.
I plan to change some of this logic to be a bit less lenient against
random reconfiguring of live interrupts but just not yet.
The ported MPIC driver has a bug where when that happens, it will mask
the interrupt. This changes it to preserve the previous masking of the
interrupt instead.

* master.kernel.org:/pub/scm/linux/kernel/git/davej/cpufreq:
Move workqueue exports to where the functions are defined.
[CPUFREQ] Misc cleanups in ondemand.
[CPUFREQ] Make ondemand sampling per CPU and remove the mutex usage in sampling path.
[CPUFREQ] Add queue_delayed_work_on() interface for workqueues.
[CPUFREQ] Remove slowdown from ondemand sampling path.
There is a code sequence where the locking is substream->self_group.lock
-> ins->scbs[index].lock
substream->self_group.lock is interrupt safe, and taken from irq context
as well (trace is snipped for brevity)
so what can happen is
cpu 0 cpu 1
user context user context
take ins->scbs[index].lock without disabling interrupts
get substream->self_group.lock (irqsafe)
try to get ins->scbs[index].lock (spins)
interrupt happens
try to get substream->self_group.lock (spins)
which is an obvious AB-BA deadlock
fix is to just take the lock with _irqsafe

mthca: initialize send and receive queue locks separately
lockdep identifies a lock by the call site of its initialization. By
initializing the send and receive queue locks in mthca_wq_init() we confuse
lockdep. It warns that that the ordered acquiry of both locks in
mthca_modify_qp() is recursive acquiry of one lock:
=============================================
[ INFO: possible recursive locking detected ]
---------------------------------------------
modprobe/1192 is trying to acquire lock:
(&wq->lock){....}, at: [<f892b4db>] mthca_modify_qp+0x60/0xa7b [ib_mthca]
but task is already holding lock:
(&wq->lock){....}, at: [<f892b4ce>] mthca_modify_qp+0x53/0xa7b [ib_mthca]
Initializing the locks separately in mthca_alloc_qp_common() stops the
warning and will let lockdep enforce proper ordering on paths that acquire
both locks.

I found a bug in memory hot-add code for ia64.
IA64's code has copies of pgdat's array on each node to reduce memory
access over crossing node. This array is used by NODE_DATA() macro. When
new node is hot-added, this pgdat's array should be updated and copied on
new node too.
However, I used for_each_online_node() in scatter_node_data() to copy
it. This meant its array is not copied on new node.
Because initialization of structures for new node was halfway,
so online_node_map couldn't be set at this time.
To copy arrays on new node, I changed it to check value of pgdat_list[]
which is source array of copies. I tested this patch with my Memory Hotadd
emulation on Tiger4. This patch is for 2.6.17-git20.
