In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

A common pattern with skb_put() is to just want to memcpy()
some data into the new space, introduce skb_put_data() for
this.
An spatch similar to the one for skb_put_zero() converts many
of the places using it:

The ksz884x driver does receive processing in a custom tasklet, and
seems to be assuming that since it takes its private interface spinlock
with spin_lock_irq(), it won't be running concurrently with its own
interrupt handler, as it cannot be preempted by it, but since its
interrupt handler doesn't do any locking whatsoever, the receive
processing tasklet and interrupt handler can end up running concurrently
on different CPUs.
As a result of this, the ksz884x receive path ends up locking up fairly
easily, when the receive processing tasklet's reenabling of receive
interrupts (due to it being done with polling the receive ring) races
with the interrupt handler's disabling of receive interrupts (due to a
new receive interrupt coming in) resulting in the receive interrupt
being masked but the receive processing tasklet not being scheduled.
Fix this by making the ksz884x interrupt handler take its private
interface spinlock. This requires upgrading the spin_lock() in the
transmit cleanup tasklet to a spin_lock_irq(), as otherwise the IRQ
handler can preempt transmit cleanup and deadlock the system, but
with those two changes, no more receive lockups have been observed.

In commit 175c0dff, drivers uses tasklet_kill to avoid put disabled tasklet
on the tasklet vec. But some of the drivers uses tasklet_init & tasklet_disable
in the driver init code, then tasklet_enable when it is opened. This makes
tasklet_enable on a killed tasklet and make ksoftirqd crazy then. Normally,
drivers should use tasklet_init/tasklet_kill on device open/remove, and use
tasklet_disable/tasklet_enable on device suspend/resume.
