babcda74e9 drivers/net: Kill now superfluous ->last_rx stores.
The generic packet receive code takes care of setting
netdev->last_rx when necessary, for the sake of the
bonding ARP monitor.

Drivers need not do it any more.

Some cases had to be skipped over because the drivers
were making use of the ->last_rx value themselves.

eda105317f dev->priv to netdev_priv(dev), drivers/net/tokenring/
Replacing accesses to dev->priv to netdev_priv(dev). The replacment
is safe when netdev_priv is used to access a private structure that is
right next to the net_device structure in memory.
Cf http://groups.google.com/group/comp.os.linux.development.system/browse_thread/thread/de19321bcd94dbb8/0d74a4adcd6177bd
This is the case when the net_device structure was allocated with
a call to alloc_netdev or one of its derivative.

Here is an excerpt of the semantic patch that performs the transformation

@ rule1 @
type T;
struct net_device *dev;
@@

 dev =
(
        alloc_netdev
|
        alloc_etherdev
|
        alloc_trdev
)
   (sizeof(T), ...)

@ rule1bis @
struct net_device *dev;
expression E;
@@
 dev->priv = E

@ rule2 depends on rule1 && !rule1bis  @
struct net_device *dev;
type rule1.T;
@@

- (T*) dev->priv
+ netdev_priv(dev)

PS: I have performed the same transformation on the whole kernel
and it affects around 70 files, most of them in drivers/net/.
Should I split my patch for each subnet directories ? (wireless/, wan/, etc)

Thanks to Thomas Surrel for helping me refining my semantic patch.

Fix by making ibmtr_probe an __init function.

While at it, move move ibmtr_probe_card below ibmtr_probe so the protoype
for ibmtr_probe can be deleted.

ee28b0da10 [PATCH] remote memory corruptor in ibmtr.c
ip_summed changes last summer had missed that one.  As the result,
we have ip_summed interpreted as CHECKSUM_PARTIAL now.  IOW,
->csum is interpreted as offset of checksum in the packet.  net/core/*
will both read and modify the value as that offset, with obvious
reasons.  At the very least it's a remote memory corruptor.

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.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
