2010-05-03Input: elantech - fix firmware version checkFlorian Ragwitz
The check determining whether device should use 4- or 6-byte packets was trying to compare firmware with 2.48, but was failing on majors greater than 2. The new check ensures that versions like 4.1 are checked properly. Signed-off-by: Florian Ragwitz <rafl@debian.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-05-03Input: ati_remote - add some missing devices from lirc_atiusbJarod Wilson
The (out-of-tree) lirc_atiusb driver has a much longer list of devices it supports. Some of them look like they may just be guesses at possible device IDs, but a few are definitely confirmed devices. This adds the nVidia-branded RF receiver and the X10 Lola Wireless Video Sender device (which contains an RF receiver) to the list of devices in ati_remote.

2010-05-04powerpc/swiotlb: Fix off by one in determining boundary of which ops to useKumar Gala
When we compare the devices DMA mask to the amount of memory we need to make sure we treat the DMA mask as an address boundary. For example if the DMA_MASK(32) and we have 4G of memory we'd incorrectly set the dma ops to swiotlb. We need to add one to the dma mask when we convert it.

2010-05-03net: ep93xx_eth stops receiving packetsDavid S. Miller
Receiving small packet(s) in a fast pace leads to not receiving any packets at all after some time. After ethernet packet(s) arrived the receive descriptor is incremented by the number of frames processed. If another packet arrives while processing, this is processed in another call of ep93xx_rx. This second call leads that too many receive descriptors getting released. This fix increments, even in these case, the right number of processed receive descriptors.

2010-05-03dm9601: fix phy/eeprom write routinePeter Korsgaard
Use correct bit positions in DM_SHARED_CTRL register for writes. Michael Planes recently encountered a 'KY-RS9600 USB-LAN converter', which came with a driver CD containing a Linux driver. This driver turns out to be a copy of dm9601.c with symbols renamed and my copyright stripped. That aside, it did contain 1 functional change in dm_write_shared_word(), and after checking the datasheet the original value was indeed wrong (read versus write bits). On Michaels HW, this change bumps receive speed from ~30KB/s to ~900KB/s. On other devices the difference is less spectacular, but still significant (~30%).

2010-05-03ppp_generic: handle non-linear skbs when passing them to pppdSimon Arlott
Frequently when using PPPoE with an interface MTU greater than 1500, the skb is likely to be non-linear. If the skb needs to be passed to pppd then the skb data must be read correctly. The previous commit fixes an issue with accidentally sending skbs to pppd based on an invalid read of the protocol type. When that error occurred pppd was reading invalid skb data too.

2010-05-03ppp_generic: pull 2 bytes so that PPP_PROTO(skb) is validSimon Arlott
In ppp_input(), PPP_PROTO(skb) may refer to invalid data in the skb. If this happens and (proto >= 0xc000 || proto == PPP_CCPFRAG) then the packet is passed directly to pppd. This occurs frequently when using PPPoE with an interface MTU greater than 1500 because the skb is more likely to be non-linear. The next 2 bytes need to be pulled in ppp_input(). The pull of 2 bytes in ppp_receive_frame() has been removed as it is no longer required. Signed-off-by: Simon Arlott <simon@fire.lp0.eu> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-05-03ceph: clear dir complete, invalidate dentry on replayed renameSage Weil
If a rename operation is resent to the MDS following an MDS restart, the client does not get a full reply (containing the resulting metadata) back. In that case, a ceph_rename() needs to compensate by doing anything useful that fill_inode() would have, like d_move(). It also needs to invalidate the dentry (to workaround the vfs_rename_dir() bug) and clear the dir complete flag, just like fill_trace(). Signed-off-by: Sage Weil <sage@newdream.net>

2010-05-03perf: record TRACE_INFO only if using tracepoints and SAMPLE_RAWTom Zanussi
The current perf code implicitly assumes SAMPLE_RAW means tracepoints are being used, but doesn't check for that. It happily records the TRACE_INFO even if SAMPLE_RAW is used without tracepoints, but when the perf data is read it won't go any further when it finds TRACE_INFO but no tracepoints, and displays misleading errors. This adds a check for both in perf-record, and won't record TRACE_INFO unless both are true. This at least allows perf report -D to dump raw events, and avoids triggering a misleading error condition in perf trace. It doesn't actually enable the non-tracepoint raw events to be displayed in perf trace, since perf trace currently only deals with tracepoint events.
