2007-02-07shpchp: remove CONFIG_HOTPLUG_PCI_SHPC_POLL_EVENT_MODEKenji Kaneshige
The CONFIG_HOTPLUG_PCI_SHPC_POLL_EVENT_MODE config option is not needed because polling mechanism for shpc hotplug events can be enabled through module option 'shpchp_poll_mode'.

This patch adds the following changes into generic PCI code especially for PCI legacy I/O port free drivers. - Added new pci_request_selected_regions() and pci_release_selected_regions() for PCI legacy I/O port free drivers in order to request/release only the selected regions. - Added helper routine pci_select_bars() which makes proper mask of BARs from the specified resource type.

2007-02-07PCI: check szhi when sz is 0 when 64 bit iomem bigger than 4GYinghai Lu
For pci mem resource that size is bigger than 4G, the sz returned by pc_size will be 0. So that resource is skipped, and register contained hi address will be treated as another 32bit resource. We need to use sz64 and pci_sz64 for 64 bit resource for clear logical. Typical usages for this: Opteron system with co-processor and the co-processor could take more than 4G RAM as pre-fetchable mem resource.

2007-02-05[S390] Convert memory detection into C code.Heiko Carstens
Hopefully this will make it more maintainable and less error prone. Code makes use of search_exception_tables(). Since it calls this function before the kernel exeception table is sorted, there is an early call to sort_main_extable(). This way it's easy to use the already present infrastructure of fixup sections. Also this would allows to easily convert the rest of head[31|64].S into C code.

2007-02-05[S390] Support for s390 Pseudo Random Number GeneratorJan Glauber
Starting with the z9 the CPU Cryptographic Assist Facility comes with an integrated Pseudo Random Number Generator. The generator creates random numbers by an algorithm similar to the ANSI X9.17 standard. The pseudo-random numbers can be accessed via a character device driver node called /dev/prandom. Similar to /dev/urandom any amount of bytes can be read from the device without blocking.

2007-02-05[S390] ETR support.Martin Schwidefsky
This patch adds support for clock synchronization to an external time reference (ETR). The external time reference sends an oscillator signal and a synchronization signal every 2^20 microseconds to keep the TOD clocks of all connected servers in sync. For availability two ETR units can be connected to a machine. If the clock deviates for more than the sync-check tolerance all cpus get a machine check that indicates that the clock is out of sync. For the lovely details how to get the clock back in sync see the code below. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2007-02-05[S390] dasd: fix bug in dasd initialization cleanupStefan Weinhuber
The initialization of the dasd_eer code is one of the last steps of the dasd driver initialization. When initialization fails in one of the earlier steps, the dasd_exit function is called to clean up what has been done so far. So the dasd_eer_exit function may be called, although the dasd_eer_init function wasn't called before and dasd_eer_exit tries to unregister a misc device that wasn't registered, which results in a BUG. Make sure that dasd_eer_exit can be called without initialization. Use a dynamically allocated struct miscdevice instead of a static one, so we only try to unregister the device if it exists and was actually registered.

Some HID devices by Apple have both keyboard and mouse interfaces; the keyboard interface is handled by usbhid, but the mouse (really touchpad) interface must be handled by the separate 'appletouch' driver.
