Commit b7802c5c1ea ("Input: psmouse - use boolean type") caused the synaptics_hardware variable to be completely useless, as it is constantly set to 'true' throughout the whole psmouse_extensions(). This was caused by the following hunk in the commit in question - int synaptics_hardware = 0; + bool synaptics_hardware = true; which is wrong and causes driver to issue extra reset when falling back to bare PS/2 protocol.

2009-11-13md/raid5: Allow dirty-degraded arrays to be assembled when only party is ↵NeilBrown
degraded. Normally is it not safe to allow a raid5 that is both dirty and degraded to be assembled without explicit request from that admin, as it can cause hidden data corruption. This is because 'dirty' means that the parity cannot be trusted, and 'degraded' means that the parity needs to be used. However, if the device that is missing contains only parity, then there is no issue and assembly can continue. This particularly applies when a RAID5 is being converted to a RAID6 and there is an unclean shutdown while the conversion is happening. So check for whether the degraded space only contains parity, and in that case, allow the assembly. Signed-off-by: NeilBrown <neilb@suse.de>
2009-11-13Don't unconditionally set in_sync on newly added device in raid5_reshapeNeilBrown
When a reshape finds that it can add spare devices into the array, those devices might already be 'in_sync' if they are beyond the old size of the array, or they might not if they are within the array. The first case happens when we change an N-drive RAID5 to an N+1-drive RAID5. The second happens when we convert an N-drive RAID5 to an N+1-drive RAID6. So set the flag more carefully. Also, ->recovery_offset is only meaningful when the flag is clear, so only set it in that case. This change needs the preceding two to ensure that the non-in_sync device doesn't get evicted from the array when it is stopped, in the case where v0.90 metadata is used. Signed-off-by: NeilBrown <neilb@suse.de>
2009-11-13md: allow v0.91 metadata to record devices as being active but not in-sync.NeilBrown
This is a combination that didn't really make sense before. However when a reshape is converting e.g. raid5 -> raid6, the extra device is not fully in-sync, but is certainly active and contains important data. So allow that start to be meaningful and in particular get the 'recovery_offset' value (which is needed for any non-in-sync active device) from the reshape_position.

2009-11-12pps: events reporting fix upRodolfo Giometti
PPS events must be recorded according to PPS's mode settings. If a process asks for (i.e.) capture-assert events only, when the PPS client calls the pps_event() function to save the current PPS event, we should verify the event type and then discard unwanted ones. Also, without this patch userland processes waiting for a specific PPS event (assert or clear but not both) may be awakened at wrong time.

2009-11-12rtc: v3020: fix v3020_mmio_read_bit()Scott Valentine
v3020_mmio_read_bit() always returns 0 when left_shift > 7. v3020_mmio_read_bit()'s return type is (unsigned char). The code returns a value masked by (1 << left_shift) that is casted to the return type. If left_shift is larger than 7, the cast will always result in a 0 return value. The problem was discovered with left_shift = 16, and the included patch corrects the problem. The bug was introduced in the last (Apr 3 2009) commit of the file, kernel versions 2.6.30 and later.

Remove fb_save_state() and fb_restore_state operations from frame buffer layer. They are used only in two drivers: 1. savagefb - and cause bug #11248 2. uvesafb Usage of these operations is misunderstood in both drivers so kill these operations, fix the bug #11248 and avoid confusion in the future. Tested on Savage 3D/MV card and the patch fixes the bug #11248. The frame buffer layer uses these funtions during switch between graphics and text mode of the console, but these drivers saves state before switching of the frame buffer (in the fb_open) and after releasing it (in the fb_release). This defeats the purpose of these operations.

2009-11-12intel-iommu: Support PCIe hot-plugFenghua Yu
To support PCIe hot plug in IOMMU, we register a notifier to respond to device change action. When the notifier gets BUS_NOTIFY_UNBOUND_DRIVER, it removes the device from its DMAR domain. A hot added device will be added into an IOMMU domain when it first does IOMMU op. So there is no need to add more code for hot add. Without the patch, after a hot-remove, a hot-added device on the same slot will not work.
