plip: replace spin_lock_irq with spin_lock_irqsave in irq context

2008-04-01T18:16:04+00:00

Plip uses spin_lock_irq/spin_unlock_irq in its IRQ handler (called from
parport IRQ handler), the latter enables interrupts without parport
subsystem IRQ handler expecting it.

The bug can be seen if you compile kernel with lock dependency checking
and use plip --- it produces a warning.

This patch changes it to spin_lock_irqsave/spin_lock_irqrestore, so that
it doesn't enable interrupts when already disabled.

plip: fix parport_register_device name parameter

2007-11-27T03:39:01+00:00

Plip passes a string "name" that is allocated on stack to
parport_register_device.  parport_register_device holds the pointer to
"name" and when the registering function exits, it points nowhere.

On some machine, this bug causes bad names to appear in /proc, such as
/proc/sys/dev/parport/parport0/devices/T^/�X^/�, on others, the plip
proc node is completely missing.

The patch also fixes documentation to note this requirement.

plip: use netif_rx_ni() for packet receive

2007-11-27T03:37:31+00:00

netif_rx is meant to be called from interrupts because it doesn't wake
up ksoftirqd.  For calling from outside interrupts, netif_rx_ni exists.

This fixes plip to use netif_rx_ni.  It fixes the infamous error "NOHZ:
local_softirq_panding 08" that happens on some machines with NOHZ and
plip --- it is caused by the fact that softirq is pending and ksoftirqd
is sleeping.

[PARPORT] Remove unused 'irq' argument from parport irq functions

2007-10-23T23:53:16+00:00

None of the drivers with a struct pardevice's ->irq_func() hook ever
used the 'irq' argument passed to it, so remove it.

[NET]: Move hardware header operations out of netdevice.

2007-10-10T23:52:52+00:00

Since hardware header operations are part of the protocol class
not the device instance, make them into a separate object and
save memory.

[NET] drivers/net: statistics cleanup #1 -- save memory and shrink code

2007-10-10T23:51:16+00:00

We now have struct net_device_stats embedded in struct net_device,
and the default ->get_stats() hook does the obvious thing for us.

Run through drivers/net/* and remove the driver-local storage of
statistics, and driver-local ->get_stats() hook where applicable.

This was just the low-hanging fruit in drivers/net; plenty more drivers
remain to be updated.

[NET]: Nuke SET_MODULE_OWNER macro.

2007-10-10T23:51:13+00:00

It's been a useless no-op for long enough in 2.6 so I figured it's time to
remove it.  The number of people that could object because they're
maintaining unified 2.4 and 2.6 drivers is probably rather small.

[SK_BUFF]: Introduce skb_mac_header()

2007-04-26T05:24:41+00:00

For the places where we need a pointer to the mac header, it is still legal to
touch skb->mac.raw directly if just adding to, subtracting from or setting it
to another layer header.

This one also converts some more cases to skb_reset_mac_header() that my
regex missed as it had no spaces before nor after '=', ugh.
