2008-01-26[S390] Change vmalloc defintionsChristian Borntraeger
Currently the vmalloc area starts at a dynamic address depending on the memory size. There was also an 8MB security hole after the physical memory to catch out-of-bounds accesses. We can simplify the code by putting the vmalloc area explicitely at the top of the kernel mapping and setting the vmalloc size to a fixed value of 128MB/128GB for 31bit/64bit systems. Part of the vmalloc area will be used for the vmem_map. This leaves an area of 96MB/1GB for normal vmalloc allocations.

2008-01-26[S390] Fix tlb flushing with idte.Martin Schwidefsky
The clear-by-asce operation of the idte instruction gets an asce (address-space-control-element) as argument to specify which TLBs need to get flushed. The current code passes a plain pointer to the start of the pgd without the additional bits which would make the pointer an asce. The current machines don't mind the difference but a future model might want to use the designation type control bits in the asce as a filter for the TLBs to flush.

2008-01-26[S390] Standby cpu activation/deactivation.Heiko Carstens
Add a new interface so that cpus can be put into standby state and configured state. Only offline cpus can be put into standby state or configured state. For that the new percpu sysfs attribute "configure" must be used. To put a cpu in standby state a "0" must be written to the attribute. In order to switch it into configured state a "1" must be written to the attribute. Only cpus in configured state can be brought online. In addition this patch introduces a static mapping of physical to logical cpus. As a result only the sysfs directories of present cpus will be created. To scan for new cpus the new sysfs attribute "rescan" must be used. Writing to /sys/devices/system/cpu/rescan will trigger a rescan of cpus and will create directories for new cpus. On IPL only configured cpus will be used. And on reboot/shutdown all cpus will remain in their current state (configured/standby).

2008-01-25IPoIB: improve IPv4/IPv6 to IB mcast mapping functionsRolf Manderscheid
An IPoIB subnet on an IB fabric that spans multiple IB subnets can't use link-local scope in multicast GIDs. The existing routines that map IP/IPv6 multicast addresses into IB link-level addresses hard-code the scope to link-local, and they also leave the partition key field uninitialised. This patch adds a parameter (the link-level broadcast address) to the mapping routines, allowing them to initialise both the scope and the P_Key appropriately, and fixes up the call sites. The next step will be to add a way to configure the scope for an IPoIB interface. Signed-off-by: Rolf Manderscheid <rvm@obsidianresearch.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2008-01-25RDMA/cma: add support for rdma_migrate_id() Sean Hefty
This is based on user feedback from Doug Ledford at RedHat: Events that occur on an rdma_cm_id are reported to userspace through an event channel. Connection request events are reported on the event channel associated with the listen. When the connection is accepted, a new rdma_cm_id is created and automatically uses the listen event channel. This is suboptimal where the user only wants listen events on that channel. Additionally, it may be desirable to have events related to connection establishment use a different event channel than those related to already established connections. Allow the user to migrate an rdma_cm_id between event channels. All pending events associated with the rdma_cm_id are moved to the new event channel.

2008-01-25ide: use do_rw_taskfile() in flagged_taskfile()Bartlomiej Zolnierkiewicz
Based on the earlier work by Tejun Heo. * Move setting IDE_TFLAG_LBA48 taskfile flag from do_rw_taskfile() function to the callers. * Add IDE_TFLAG_FLAGGED taskfile flag for flagged taskfiles coming from ide_taskfile_ioctl(). Check it instead of ->tf_out_flags.all. * Add IDE_TFLAG_OUT_DATA taskfile flag to indicate the need to load IDE data register in ide_tf_load(). * Add IDE_TFLAG_OUT_* taskfile flags to indicate the need to load particular IDE taskfile registers in ide_tf_load(). * Update do_rw_taskfile() and ide_tf_load() users to set respective IDE_TFLAG_OUT_* taksfile flags. * Add task_dma_ok() helper. * Use IDE_TFLAG_FLAGGED taskfile flag to select HIHI mask in ide_tf_load(). * Use do_rw_taskfile() in flagged_taskfile(). * Remove no longer needed 'tf_out_flags' field from ide_task_t. There should be no functionality changes caused by this patch. Cc: Tejun Heo <htejun@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-01-25ide: add ide_no_data_taskfile() helperBartlomiej Zolnierkiewicz
* Add ide_no_data_taskfile() helper and convert ide_raw_taskfile() w/ NO DATA protocol users to use it instead. * Set ->data_phase explicitly in ide_no_data_taskfile() (TASKFILE_NO_DATA is defined as 0x0000). * Unexport task_no_data_intr().

2008-01-25ide: add ide_tf_load() helperBartlomiej Zolnierkiewicz
Based on the earlier work by Tejun Heo. * Add 'tf_flags' field (for taskfile flags) to ide_task_t. * Add IDE_TFLAG_LBA48 taskfile flag for LBA48 taskfiles. * Add IDE_TFLAG_NO_SELECT_MASK taskfile flag for __ide_do_rw_disk() which doesn't use SELECT_MASK() (looks like a bug but it requires some more investigation). * Split off ide_tf_load() helper from do_rw_taskfile(). * Convert __ide_do_rw_disk() to use ide_tf_load(). There should be no functionality changes caused by this patch.

2008-01-25ide: add struct ide_taskfile (take 2)Bartlomiej Zolnierkiewicz
* Don't set write-only ide_task_t.hobRegister[6] and ide_task_t.hobRegister[7] in idedisk_set_max_address_ext(). * Add struct ide_taskfile and use it in ide_task_t instead of tfRegister[] and hobRegister[]. * Remove no longer needed IDE_CONTROL_OFFSET_HOB define. * Add #ifndef/#endif __KERNEL__ around definitions of {task,hob}_struct_t. While at it: * Use ATA_LBA define for LBA bit (0x40) as suggested by Tejun Heo. v2: * Add missing newlines. (Noticed by Sergei) * Use ~ATA_LBA instead of 0xBF. (Noticed by Sergei) * Use unnamed unions for error/feature and status/command. (Suggested by Sergei). There should be no functionality changes caused by this patch.

2008-01-25V4L/DVB (7002): cx25840: Add basic CX23885 AVCore supportSteven Toth
The cx23885/7/8 PCIe bridge has an internal AVCore modelled on the cx2584x family. Many of the registers positions are identical but some moved. The register values are also different because the different bridges run at different clock rates.

2008-01-25V4L/DVB (6997): Replace a very dirty hack on videobuf for a clean wait_eventMauro Carvalho Chehab
In order to videobuf_iolock to work, mmap_mapper should be called first. Otherwise, an OOPS is generated. On some cases, .mmap file handler used to took some time to be called. On those situations, mmap_mmapper() were called after iolock. This patch properly waits for mmap_mapper to be called, otherwise generating an error.
