2006-06-29[PATCH] genirq: rename desc->handler to desc->chipIngo Molnar
This patch-queue improves the generic IRQ layer to be truly generic, by adding various abstractions and features to it, without impacting existing functionality. While the queue can be best described as "fix and improve everything in the generic IRQ layer that we could think of", and thus it consists of many smaller features and lots of cleanups, the one feature that stands out most is the new 'irq chip' abstraction. The irq-chip abstraction is about describing and coding and IRQ controller driver by mapping its raw hardware capabilities [and quirks, if needed] in a straightforward way, without having to think about "IRQ flow" (level/edge/etc.) type of details. This stands in contrast with the current 'irq-type' model of genirq architectures, which 'mixes' raw hardware capabilities with 'flow' details. The patchset supports both types of irq controller designs at once, and converts i386 and x86_64 to the new irq-chip design. As a bonus side-effect of the irq-chip approach, chained interrupt controllers (master/slave PIC constructs, etc.) are now supported by design as well. The end result of this patchset intends to be simpler architecture-level code and more consolidation between architectures. We reused many bits of code and many concepts from Russell King's ARM IRQ layer, the merging of which was one of the motivations for this patchset. This patch: rename desc->handler to desc->chip. Originally i did not want to do this, because it's a big patch. But having both "desc->handler", "desc->handle_irq" and "action->handler" caused a large degree of confusion and made the code appear alot less clean than it truly is. I have also attempted a dual approach as well by introducing a desc->chip alias - but that just wasnt robust enough and broke frequently. So lets get over with this quickly. The conversion was done automatically via scripts and converts all the code in the kernel. This renaming patch is the first one amongst the patches, so that the remaining patches can stay flexible and can be merged and split up without having some big monolithic patch act as a merge barrier.

2006-06-29[S390] rework of channel measurement facility.Cornelia Huck
Fixes for several channel measurement facility bugs: * Blocks copied from the hardware might not be consistent. Solve this by moving the copying into idle state and repeating the copying. * avg_sample_interval changed with every read, even though no new block was available. Solve this by storing a timestamp when the last new block was received. * Several locking issues. * Measurements were not reenabled after a disconnected device became available again. * Remove #defines for ioctls that were never implemented.

2006-06-29[S390] cio chpid offline.Cornelia Huck
After setting a path to a dasd offline at the SE, I/O hangs on that dasd for 5 minutes, then continues. I/O for which an interrupt will not be reported after the channel path has been disabled was not terminated by the common I/O layer, causing the dasd MIH to hit after 5 minutes. Be more aggressive in terminating I/O after setting a channel path offline. Also make sure to generate a fake irb if the device driver issues an I/O request after being notified of the killed I/O and clear residual information from the irb before trying to start the delayed verification.

2006-06-29[S390] ccwgroup device unregister.Cornelia Huck

This works because driver_get_device() gets us out of the region of the elevated klist node refcount. driver_find_device() will always get the next device in the list after the found one has been unregistered.

2006-06-28[PATCH] SPI: infrastructure to initialize spi_device.mode earlyDavid Brownell
This patch adds earlier initialization of spi_device.mode, as needed on boards using nondefault chipselect polarity. An example would be ones using the RS5C348 RTC without an external signal inverter between the RTC chipselect and the SPI controller. Without this mechanism, the first setup() call for that chip would wrongly enable chips, corrupting transfers to/from other chips sharing that SPI bus.

2006-06-28[PATCH] remove active field from tty buffer structurePaul Fulghum
Remove 'active' field from tty buffer structure. This was added in 2.6.16 as part of a patch to make the new tty buffering SMP safe. This field is unnecessary with the more intelligently written flush_to_ldisc that adds receive_room handling. Removing this field reverts to simpler logic where the tail buffer is always the 'active' buffer, which should not be freed by flush_to_ldisc. (active == buffer being filled with new data) The result is simpler, smaller, and faster tty buffer code.

2006-06-28[PATCH] remove TTY_DONT_FLIPPaul Fulghum
Remove TTY_DONT_FLIP tty flag. This flag was introduced in 2.1.X kernels to prevent the N_TTY line discipline functions read_chan() and n_tty_receive_buf() from running at the same time. 2.2.15 introduced tty->read_lock to protect access to the N_TTY read buffer, which is the only state requiring protection between these two functions. The current TTY_DONT_FLIP implementation is broken for SMP, and is not universally honored by drivers that send data directly to the line discipline receive_buf function. Because TTY_DONT_FLIP is not necessary, is broken in implementation, and is not universally honored, it is removed.
