6e9ebcfa20 TTY: simserial, final cleanup
* remove pointless checks (tty cannot be NULL at that points)
* fix some printks (use __func__, print text directly w/o using global
  strings)
* remove some empty lines

This is the last patch for simserial. Overall, the driver is 400 lines
shorter. Being now at 560 lines.

It was tested using ski with a busybox userspace.

458cd31a4c TTY: simserial, use tty_port_hangup
Convert shutdown to be tty_port_operations->shutdown. Then we can use
tty_port_hangup. (And we have to use tty_port_close.)

This means we no longer touch ASYNC_INITIALIZED, TTY_IO_ERROR. Also we
do not need to do any peculiar TTY logic in the file now.

9aead90a7f TTY: simserial, use tty_port_open
So now we convert startup to be ->activate of tty_port. This means we
no longer care about INITIALIZED and TTY_IO_ERROR flags.

After we have ->activate much of the code may go as it duplicates what
tty_port_open does. In this case tty_port_open adds block_til_ready to
the path. But we do not define carrier hooks, so it is a noop.

fd2d7a6e60 TTY: simserial, remove static initialization
We do not use any of the preinitialized rs_state members for something
real. So there is no need to initialize them. At the places we used
them for printing, just print the values.

And since only one port is supported, get rid of the loop. This
simplifies simrs_init a heap. Thus we can handle fail paths in a
standard way without panicing.

964105b501 TTY: simserial, remove support of shared interrupts
It never worked there. The ISR was never written for that kind of
stuff. So remove all that crap with a hash of linked lists and pass
the pointer directly to the ISR.

BTW this answers the question there:
  * I don't know exactly why they don't use the dev_id opaque data
  * pointer instead of this extra lookup table

-> Because they thought they will support more devices bound to a
single interrupt w/o IRQF_SHARED. They would need exactly the hash
there.

What I don't understand is rebinding of the interrupt in the shutdown
path. They perhaps meant to do just synchronize_irq? In any case, this
is all gone and free_irq there properly.

By removing the hash we save some bits (exactly NR_IRQS * 8 bytes of
.bss and over a kilo of .text):
before:
   text    data     bss     dec     hex filename
  19600     320    8227   28147    6df3 ../a/ia64/arch/ia64/hp/sim/simserial.o
after:
   text    data     bss     dec     hex filename
  18568     320      28   18916    49e4 ../a/ia64/arch/ia64/hp/sim/simserial.o

Note that a shared interrupt could not work too. request_irq requires
data parameter to be non-NULL. So the whole IRQ_T exercise was
pointless.

Finally, this helps us remove another two members of async_struct :).

9e12dd5fce simserial, bail out when request_irq fails
Without this, the code succeeds when the port is opened by root and we
get unwanted interrupts storm on the first key stroke.

Instead of that, tell the user we failed and that we won't continue. I
suppose, the code was copied from the serial layer where we may want
to change the irq number, so we must allow open even of the failing
port. This is not the case for this driver at all.

6efb6b77ff hpsim, initialize chip for assigned irqs
Currently, when assign_irq_vector is called and the irq connected in
the simulator, the irq is not ready. request_irq will return ENOSYS
immediately. It is because the irq chip is unset.

Hence set the chip properly to irq_type_hp_sim. And make sure this is
done from both users of simulated interrupts.

Also we have to set handler here, otherwise we end up in
handle_bad_int resulting in spam in logs and no irqs handled. We use
handle_simple_irq as these are SW interrupts that need no ACK or
anything.

* which are unused or
* which are only initialized and never used for something real.

Everybody should avoid the structures with a looong distance.

Finally, remove the ALPHA kludge MCR quirks. They are 1:1 copy from

10e82f6ce7 tty: simserial: now phase out the ioctl file pointer for good
Alan missed the ia64 simulator serial driver (because it was hidden
in arch/... rather than located under drivers/... where one might
expect to find a driver).  Drop the "file *" argument from rs_ioctl()
in arch/ia64/hp/sim/simserial.c

f281233d3e SCSI host lock push-down
Move the mid-layer's ->queuecommand() invocation from being locked
with the host lock to being unlocked to facilitate speeding up the
critical path for drivers who don't need this lock taken anyway.

The patch below presents a simple SCSI host lock push-down as an
equivalent transformation.  No locking or other behavior should change
with this patch.  All existing bugs and locking orders are preserved.

Additionally, add one parameter to queuecommand,
	struct Scsi_Host *
and remove one parameter from queuecommand,
	void (*done)(struct scsi_cmnd *)

Scsi_Host* is a convenient pointer that most host drivers need anyway,
and 'done' is redundant to struct scsi_cmnd->scsi_done.

Minimal code disturbance was attempted with this change.  Most drivers
needed only two one-line modifications for their host lock push-down.

6ed106549d net: use NETDEV_TX_OK instead of 0 in ndo_start_xmit() functions
This patch is the result of an automatic spatch transformation to convert
all ndo_start_xmit() return values of 0 to NETDEV_TX_OK.

Some occurences are missed by the automatic conversion, those will be
handled in a seperate patch.

fb824f4838 [IA64] remove obsolete hw_interrupt_type
The defines and typedefs (hw_interrupt_type, no_irq_type, irq_desc_t) have
been kept around for migration reasons.  After more than two years it's
time to remove them finally.

This patch cleans up one of the remaining users.  When all such patches
hit mainline we can remove the defines and typedefs finally.

Impact: cleanup

Convert the last remaining users to struct irq_chip and remove the
define.

d5dedd4507 irq: change ->set_affinity() to return status
according to Ingo, change set_affinity() in irq_chip should return int,
because that way we can handle failure cases in a much cleaner way, in
the genirq layer.
