2008-02-19libata: update ATAPI overflow drainingTejun Heo
For misc ATAPI commands which transfer variable length data to the host, overflow can occur due to application or hardware bug. Such overflows can be ignored safely as long as overflow data is properly drained. libata HSM implementation has this implemented in __atapi_pio_bytes() and recently updated for 2.6.24-rc but it requires further improvements. Improve drain logic such that... * Report overflow errors using ehi desc mechanism instead of printing directly. * Properly calculate the number of bytes to be drained considering actual number of consumed bytes for partial draining.

2008-02-19genirq: do not leave interupts enabled on free_irqThomas Gleixner
The default_disable() function was changed in commit: 76d2160147f43f982dfe881404cfde9fd0a9da21 genirq: do not mask interrupts by default It removed the mask function in favour of the default delayed interrupt disabling. Unfortunately this also broke the shutdown in free_irq() when the last handler is removed from the interrupt for those architectures which rely on the default implementations. Now we can end up with a enabled interrupt line after the last handler was removed, which can result in spurious interrupts. Fix this by adding a default_shutdown function, which is only installed, when the irqchip implementation does provide neither a shutdown nor a disable function.

The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values.

2008-02-19elevator: make elevator_get() attempt to load the appropriate moduleJens Axboe
Currently we fail if someone requests a valid io scheduler, but it's modular and not currently loaded. That can happen from a driver init asking for a different scheduler, or online switching through sysfs as requested by a user. This patch makes elevator_get() request_module() to attempt to load the appropriate module, instead of requiring that done manually. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2008-02-19cfq-iosched: add hlist for browsing parallel to the radix treeJens Axboe

Commit b2e895dbd80c420bfc0937c3729b4afe073b3848 #if 0'ed this code stating: <-- snip --> [PATCH] revert blockdev direct io back to 2.6.19 version Andrew Vasquez is reporting as-iosched oopses and a 65% throughput slowdown due to the recent special-casing of direct-io against blockdevs. We don't know why either of these things are occurring. The patch minimally reverts us back to the 2.6.19 code for a 2.6.20 release. <-- snip --> It has since been dead code, and unless someone wants to revive it now it's time to remove it.

2008-02-19fix historic ioremap() abuse in AGPArjan van dev Ven
Several AGP drivers right now use ioremap_nocache() on kernel ram in order to turn a page of regular memory uncached. There are two problems with this: 1) This is a total nightmare for the ioremap() implementation to keep various mappings of the same page coherent. 2) It's a total nightmare for the AGP code since it adds a ton of complexity in terms of keeping track of 2 different pointers to the same thing, in terms of error handling etc etc. This patch fixes this by making the AGP drivers use the new set_memory_XX APIs instead. Note: amd-k7-agp.c is built on Alpha too, and generic.c is built on ia64 as well, which do not yet have the set_memory_*() APIs, so for them some we have a few ugly #ifdefs - hopefully they'll be fixed soon.

2008-02-19ide-cd: fix missing residual count setting in DMA modeKiyoshi Ueda
This patch fixes the missing residual count setting in DMA mode, which was introduced during the conversion to blk-end-request. The residual count could be used by the request submitter. So if it isn't set correctly, some upper layers does not work. (e.g. wodim for CD burning.) The bug is in only DMA mode. In PIO mode, we are setting the residual count correctly, so no need to fix.
