2012-03-09TTY: simserial, use tty_port_hangupJiri Slaby1-57/+7
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.

2012-03-09TTY: simserial, use tty_port_openJiri Slaby1-59/+5
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.

2012-03-09TTY: simserial, remove static initializationJiri Slaby1-67/+27
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.

2012-03-09TTY: simserial, remove support of shared interruptsJiri Slaby1-57/+7
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 :).

2012-03-09simserial, bail out when request_irq failsJiri Slaby1-8/+1
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.

2012-03-09hpsim, initialize chip for assigned irqsJiri Slaby5-31/+35
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.

2012-03-08TTY: remove unneeded tty->index checksJiri Slaby2-12/+5
Checking if tty->index is in bounds is not needed. The tty has the index set in the initial open. This is done in get_tty_driver. And it can be only in interval <0,driver->num).

2012-02-09tty: serial: OMAP: block idle while the UART is transferring data in PIO modePaul Walmsley1-4/+4
Prevent OMAP UARTs from going idle while they are still transferring data in PIO mode. This works around an oversight in the OMAP UART hardware present in OMAP34xx and earlier: an idle UART won't send a wakeup when the TX FIFO threshold is reached. This causes long delays during data transmission when the MPU powerdomain enters a low-power mode. The MPU interrupt controller is not able to respond to interrupts when it's in a low-power state, so the TX buffer is not refilled until another wakeup event occurs. This fix changes the erratum i291 DMA idle workaround. Rather than toggling between force-idle and no-idle, it will toggle between smart-idle and no-idle. The important part of the workaround is the no-idle part, so this shouldn't result in any change in behavior. This fix should work on all OMAP UARTs. Future patches intended for the 3.4 merge window will make this workaround conditional on a "feature" flag, and will use the OMAP36xx+ TX event wakeup support. Thanks to Kevin Hilman <khilman@ti.com> for mentioning the erratum i291 workaround, which led to the development of this approach.

2012-02-04avr32: select generic atomic64_t supportFabio Baltieri1-0/+1
Enable use of the generic atomic64 implementation on AVR32 platforms. Without this the kernel fails to build as the architecture does not provide its version.

2012-02-04xtensa: fix memscan()Akinobu Mita1-3/+0
Defining memscan() as memchr() is wrong, because the return values of memscan() and memchr() are different when the character is not found. So use the generic memscan() implementation to fix this.

2012-02-03ARM: 7314/1: kuser: consistently use usr_ret for returning from helpersWill Deacon1-1/+1
__kuser_cmpxchg64 has a return path using bx lr to get back to the caller. This is actually ok since the code in question is predicated on CONFIG_CPU_32v6K, but for the sake of consistency using the usr_ret macro is probably better.
