ba685fb2ab fix realtek phy id in forcedeth
As noticed by Chuck Ebbert, commit c5e3ae8823
introduced a copy-paste typo, as realtek phy is 0x732 and not 0x1c1. Obvious
fix below suggested by Ayaz Abdulla.

1a2b73302a fix random hang in forcedeth driver when using netconsole
If the forcedeth driver receives too much work in an interrupt, it
assumes it has a broken hardware with stuck IRQ.  It works around the
problem by disabling interrupts on the nic but makes a printk while
holding device spinlog - which isn't smart thing to do if you have
netconsole on the same nic.

This patch moves the printk's out of the spinlock protected area.

Without this patch the machine hangs hard.  With this patch everything
still works even when there is significant increase on CPU usage while
using the nic.

44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

2cc49a5ca1 forcedeth: use unicast receive mode for WoL
I happened to notice that a system with an NVidia NIC using the
forcedeth driver won't wake-on-LAN if the interface was in promiscuous
mode when you power off.  By experiment, it looks like
the hardware needs to have NvRegPacketFilterFlags set to
NVREG_PFF_ALWAYS|NVREG_PFF_MYADDR (i.e., receive unicast packets to my
address) in order for WoL to work.

Tobias Diedrich <ranma@tdiedrich.de> sayeth:

Vanilla forcedeth doesn't seem to support suspend and an ifdown/up-cycle is
needed to get it working again after suspend.  Francois Romieu's "Awfully
experimental" patch is working just fine for me (with message signalled
interrupts disabled) and has survived quite a few suspend/resume cycles.

So I'd very much like to see (at least partial, with msi disabled)
suspend support for forcedeth in mainline.

7d12e780e0 IRQ: Maintain regs pointer globally rather than passing to IRQ handlers
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around.  On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable.  On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions.  Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller.  A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs.  Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

	struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

	set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

	-	update_process_times(user_mode(regs));
	-	profile_tick(CPU_PROFILING, regs);
	+	update_process_times(user_mode(get_irq_regs()));
	+	profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

 (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
     the input_dev struct.

 (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
     something different depending on whether it's been supplied with a regs
     pointer or not.

 (*) Various IRQ handler function pointers have been moved to type
     irq_handler_t.

46798c897e [PATCH] fix possible NULL ptr deref in forcedeth
There seems to be a possible NULL pointer deref bug in
drivers/net/forcedeth.c::nv_loopback_test().  If dev_alloc_skb() fails, the
next line will call skb_put() with a NULL first argument which it'll then
try to deref - kaboom: a NULL pointer deref.  Found by coverity (#1337).

Manually resolved conflicts in drivers/net/ixgb/ixgb_main.c and
drivers/net/sky2.c related to CHECKSUM_HW/CHECKSUM_PARTIAL changes by
commit 84fa7933a3 that just happened to be
next to unrelated changes in this update.

84fa7933a3 [NET]: Replace CHECKSUM_HW by CHECKSUM_PARTIAL/CHECKSUM_COMPLETE
Replace CHECKSUM_HW by CHECKSUM_PARTIAL (for outgoing packets, whose
checksum still needs to be completed) and CHECKSUM_COMPLETE (for
incoming packets, device supplied full checksum).

Patch originally from Herbert Xu, updated by myself for 2.6.18-rc3.

2a2fc64481 [PATCH] cleanup unnecessary forcedeth printk
This removes unnecessary messages that show up every time I put my
ethernet card in promiscuous mode.  I'm already getting notification
from the networking layer, I don't need notification from the driver as
well.

There are probably other drivers that do this as well -- I'll look
around and see what I can find.
