2009-05-02ibft: fix the display of a few fields in the NIC attribute structure in sysfsAshutosh Naik
Fix the display of a few fields in the iBFT NIC attribute structure in sysfs. Ensure that, if the DHCP IP address and the subnet mask for the interface is present in the iBFT NIC structure, the corresponding entries are created in sysfs tree for the device. This would hence create the additional entries in the tree based on the iBFT table and would not delete any existing entries.

2009-05-02vgacon: return the upper half of 512 character fontsStefan Bader
Uwe Geuder noted that he gets random bitmaps on a text console if he tried to type extended characters (like the e acute). For him everything above unicode 0xa0 was corrupted. After some digging there seems to be a little culprit in vgacon since the beginning of ages (well git). The function vgacon_font_get will store the number of characters correctly in font->charcount but then calls to vgacon_do_font_op(..., 0, 0). Which means only the lower 256 characters are actually stored to the fontdata. The rest is left untouched. So the next time that saved data is used, the garbled font appears. This happens on every switch between text consoles.

2009-05-02acpica: validate package element more carefully in ↵Robert Moore
acpi_rs_get_pci_routing_table_length acpi_rs_get_pci_routing_table_length is not performing sufficient validation on the package returned from _PRT. It assumes a package of packages and fails/faults if this is not the case. We should validate each subpackage when extracted from the parent package, and not accept objects of the wrong type, since that will just cause the scanning to fail (likely with a kernel oops). This can only happen with a serious BIOS bug, and is accompanied by a warning something like this: ACPI Warning (nspredef-0949): \_SB_.PCI0.PEG4._PRT: Return Package type mismatch at index 0 - found Integer, expected Package [20090320] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

A regression was introduced in hg changeset 33810c734a0d, which resulted in a kernel panic whenever the device was disconnected from USB. The call to 4l2_device_register() was overwriting the pointer for usb_set_intfdata(), so when au0828_usb_disconnect() was called, the usb_get_intfdata() returned a pointer to the v4l2_device instead of the au0828_dev structure.

2009-04-29V4L/DVB (11561a): move media after i2cGuennadi Liakhovetski
Currently drivers/media drivers are linked very early - directly after base, block, misc, and mfd and before ata, scsi, ide, input, firewire, usb, and i2c. This breaks static build of video4linux drivers, that use generic CPU i2c adapter drivers and the v4l2-subdev subsystem, because during video4linux probing the v4l2-subdev core requires a struct i2c_adapter context, which cannot be satisfied before the i2c subsystem is initialised. Moving drivers/media after drivers/i2c fixes this problem. The best way to trigger action is by submitting a patch:-) So, let's see what comes out of it - on the one hand I don't see any reason why media has to be linked this early, and nobody was able to give me one yesterday as this problem has been discussed on linux-media, OTOH, maybe indeed it would be better to move i2c the whole way up above media, but that'd be much bigger of a change, I think. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-04-28e100: do not go D3 in shutdown unless system is powering offThadeu Lima de Souza Cascardo
After experimenting with kexec with the last merges after 2.6.29, I've had some problems when probing e100. It would not read the eeprom. After some bisects, I realized this has been like that since forever (at least 2.6.18). The problem is that shutdown is doing the same thing that suspend does and puts the device in D3 state. I couldn't find a way to get the device back to a sane state in the probe function. So, based on some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe, I wrote this one for e100.

2009-04-28hd: fix lockingTejun Heo
hd dance around local irq and HD_IRQ enable without achieving much. It ends up transferring data from irq handler with both local irq and HD_IRQ disabled. The only place it actually does something is while transferring the first block of a request which it does with HD_IRQ disabled but local irq enabled. Unfortunately, the dancing is horribly broken from locking POV. IRQ and timeout handlers access block queue without grabbing the queue lock and running the driver in SMP configuration crashes the whole machine pretty quickly. Remove meaningless irq enable/disable dancing and add proper locking in issue, irq and timeout paths. Signed-off-by: Tejun Heo <tj@kernel.org>

2009-04-28Input: add detailed multi-touch finger data report protocolHenrik Rydberg
In order to utilize the full power of the new multi-touch devices, a way to report detailed finger data to user space is needed. This patch adds a multi-touch (MT) protocol which allows drivers to report details for an arbitrary number of fingers. The driver sends a SYN_MT_REPORT event via the input_mt_sync() function when a complete finger has been reported. In order to stay compatible with existing applications, the data reported in a finger packet must not be recognized as single-touch events. In addition, all finger data must bypass input filtering, since subsequent events of the same type refer to different fingers. A set of ABS_MT events with the desired properties are defined. The events are divided into categories, to allow for partial implementation. The minimum set consists of ABS_MT_TOUCH_MAJOR, ABS_MT_POSITION_X and ABS_MT_POSITION_Y, which allows for multiple fingers to be tracked. If the device supports it, the ABS_MT_WIDTH_MAJOR may be used to provide the size of the approaching finger. Anisotropy and direction may be specified with ABS_MT_TOUCH_MINOR, ABS_MT_WIDTH_MINOR and ABS_MT_ORIENTATION. Devices with more granular information may specify general shapes as blobs, i.e., as a sequence of rectangular shapes grouped together by a ABS_MT_BLOB_ID.

2009-04-28Input: bcm5974 - Add support for the Macbook 5 (Unibody)Henrik Rydberg
This patch adds support for the new unibody Macbook, with physically integrated button and trackpad. Since the integrated button changes the logic for touch-and-click, a device capability bit mask is now reported in input_id.version, which can be picked up by user space via a EVIOCGID call.

2009-04-28Input: bcm5974 - add quad-finger tappingHenrik Rydberg
The integrated button on the new unibody Macbooks presents a need to report explicit four-finger actions. Evidently, the finger pressing the button is also touching the trackpad, so in order to fully support three-finger actions, the driver must be able to report four-finger actions. This patch adds a new button, BTN_TOOL_QUADTAP, which achieves this. Signed-off-by: Henrik Rydberg <rydberg@euromail.se> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2009-04-28Input: bcm5974 - prepare for a new trackpad header typeHenrik Rydberg

2009-04-27RDMA/nes: Fix hang issues for large cluster dynamic connectionsFaisal Latif
Running large cluster setup, we are hanging after many hours of testing. Fixing this required going over the code and making sure the rexmit entry was properly removed based on the cm_node's state and packet received. Also when receiving a FIN packet, check seq# and make sure there were no errors before calling handle_fin(). Following are the changes done in nes_cm.c: * handle_ack_pkt() needs to return error value, so in case of error, handle_fin() is not called. Some cleanup done while going over the code. * handle_rst_pkt(), handling of cm_node's NES_CM_STATE_LAST_ACK is missing. * process_packet(), in case of FIN only packet is received, call check_seq() before processing. * in handle_fin_pkt(), we are calling cleanup_retrans_entry() for all conditions, even if the packets need to be dropped.
