| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | TTY: simserial, use tty_port_openJiri Slaby2012-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | TTY: simserial, remove support of shared interruptsJiri Slaby2012-03-08

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 :).

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* SCSI host lock push-downJeff Garzik2010-11-16
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* net: use NETDEV_TX_OK instead of 0 in ndo_start_xmit() functionsPatrick McHardy2009-07-05
| | | | | | | | | | | 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. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

* [IA64] remove obsolete hw_interrupt_typeThomas Gleixner2009-06-15
| | | | | | | | | | | | | | | | | | 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.
