* MIPS: Don't unmap the memory for dma_sync*.David Daney2008-10-27
| | | | | | | | | We were getting away with this for so long only because the only platform with a non-empty plat_unmap_dma_mem() doesn't call dma_sync_sg_for_cpu() and dma_sync_sg_for_device() from its commonly used drivers.

| * md: allow extended partitions on md devices.NeilBrown2008-10-20
| | | | | | | | | | | | | | | | | | | | The new extended partition support provides a much nicer was to have partitions on md devices that the 'mdp' alternate major. We cannot really get rid of 'mdp' at this time, but we can enable extended partitions as that will probably make life easier for sysadmins. Signed-off-by: NeilBrown <neilb@suse.de>
| * md: use sysfs_notify_dirent to notify changes to md/dev-xxx/stateNeilBrown2008-10-20
| | | | | | | | | | | | | | | | | | | | The 'state' file for a device reports, for example, when the device has failed. Changes should be reported to userspace ASAP without the possibility of blocking on low-memory. sysfs_notify does have that possibility (as it takes a mutex which can be held across a kmalloc) so use sysfs_notify_dirent instead.

| * md: use sysfs_notify_dirent to notify changes to md/array_stateNeilBrown2008-10-20
| | | | | | | | | | | | | | | | | | Now that we have sysfs_notify_dirent, use it to notify changes to md/array_state. As sysfs_notify_dirent can be called in atomic context, we can remove the delayed notify and the MD_NOTIFY_ARRAY_STATE flag. Signed-off-by: NeilBrown <neilb@suse.de>

It turned out to be correct in the first place: a positive value should be sent when the wheel is moved to the right, and a negative value when moved to the left. This is the behavior expected by the Xorg evdev driver. I must have had a remapping somewhere else in my system when originally testing this. Testing on another system shows that the unpatched kernel is correct.

The callback never inserts into ->rdllink while the send loop is performed, and also does the ~EP_PRIVATE_BITS test. Given we're holding the mutex during this time, the conditions tested inside the loop are always true. HOWEVER. The test "!ep_is_linked(&epi->rdllink)" wasn't there because we insert into ->rdllink, but because the send-events loop might terminate before the whole list is scanned (-EFAULT). In such cases, when the loop terminates early, and when a (leftover) file received an event while we're performing the lockless loop, we need such test to avoid to double insert the epoll items. The list_splice() done a few steps below, will correctly re-insert the ones that were left on "txlist". This should fix the kenrel.org bugzilla entry 11831.

* | | | | | | select: deal with math overflow from borderline valid userland dataArjan van de Ven2008-10-26

The old kernels accepted this just fine, so the new kernels must too. However, due to the upscaling of the microseconds to nanoseconds we had some cases where we got math overflow, and depending on the GCC version (due to inlining decisions) that actually resulted in an -EINVAL return. This patch fixes this by adding the excess microseconds to the seconds field. Also with thanks to Marcin Slusarz for spotting some implementation bugs in the diagnostics patches.

* | | | | | | wireless: fix regression caused by regulatory config optionArjan van de Ven2008-10-26

I don't think even the October 2008 releases of the various distros has the new userland so clearly the default is wrong, and also we can't just go about deleting this in 2.6.29... Change the default to "y" and also adjust the config text a little to reflect this.

Though this is not a huge problem, it is inconsistent with other sensor names, and with other similar hwmon drivers. Additionally, the DMI nag message added in 2.6.27 was missing a space between two sentence fragments -- might as well clean that up too. Doesn't alter any kernel text, just data.
