Stephen Rothwell points out that this file got deleted (on purpose) by commit 640c1bce ("USB: delete airprime driver"), but then almost immediately incorrectly resurrected by commit 95da310e ("usb_serial: API all change"). Delete it again. If it comes back, we'll need to drive a stake through its heart. Reported-by:

Add run time control for receive DMA buffer fill level to allow application to control receive latency when using stream oriented serial protocols that pass receive data to application only after a DMA buffer fills. This was previously a compile time option, but run time control is needed when application changes data rate (and latency requirements) or uses different data rates on different ports. Signed-off-by:

With SMP kernels _irqsave spinlock disables only local interrupts, while the shared serial interrupt could be assigned to the CPU that is not currently starting up the serial port. This might cause issues because serial8250_startup() routine issues IRQ-triggering operations before registering the port in the IRQ chain (though, this is fine to do and done explicitly because we don't want to process any interrupts on the port startup). With RT kernels and preemptable hardirqs, _irqsave spinlock does not disable local hardirqs, and the bug could be reproduced much easily: $ cat /dev/ttyS0 & $ cat /dev/ttyS1 irq 42: nobody cared (try booting with the "irqpoll" option) Call Trace: [C0475EB0] [C0008A98] show_stack+0x4c/0x1ac (unreliable) [C0475EF0] [C004BBD4] __report_bad_irq+0x34/0xb8 [C0475F10] [C004BD38] note_interrupt+0xe0/0x308 [C0475F50] [C004B09C] thread_simple_irq+0xdc/0x104 [C0475F70] [C004B3FC] do_irqd+0x338/0x3c8 [C0475FC0] [C00398E0] kthread+0xf8/0x100 [C0475FF0] [C0011FE0] original_kernel_thread+0x44/0x60 handlers: [<c02112c4>] (serial8250_interrupt+0x0/0x138) Disabling IRQ #42 After this, all serial ports on the given IRQ are non-functional. To fix the issue we should explicitly disable shared IRQ before issuing any IRQ-triggering operations. I also changed spin_lock_irqsave to the ordinary spin_lock, since it seems to be safe: chain does not contain new port (yet), thus nobody will interfere us from the ISRs. Signed-off-by:

Fix the epca driver to call epca_setup() if digiepca=xxx is included on the command line and the epca driver is built in. epca_setup() used to be called from init/main.c in 2.2 kernels, but somewhere along the way that call was removed but not replaced. Signed-off-by:

Fix the Stallion driver's putchar() and break_ctl() ops and iStallion's putchar() to return values. Is it actually possible for putchar() or break_ctl() to be called with tty == NULL or can the check be discarded? Should stl_write() be returning 0 if tty->driver_data is NULL or tx.buf is NULL? Is this even possible? I've made Stallion's functions return -EINVAL as stli_breakctl() if the checks fail. Signed-off-by:

Some hardware needs to do break handling itself and may have partial support only. Make break_ctl return an error code. Add a tty driver flag so you can indicate driver hardware side break support. Signed-off-by:
