2007-02-07PCI: cleanup MSI codeSatoru Takeuchi
Cleanup MSI code as follows: - fix some types - fix strange local variable definition - delete unnecessary blank line - add comment to #endif which is far from corresponding #ifdef Signed-off-by: Satoru Takeuchi <takeuchi_satoru@jp.fujitsu.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2007-02-07PCI: Speed up the Intel SMBus unhiding quirkJean Delvare
Speed up the Intel SMBus PCI quirk by avoiding tests which can only fail. This also makes the compiled code significantly smaller when using gcc 3.2/3.4. gcc 4.x appears to optimize the code by itself so this change doesn't make a difference there.

2007-02-07PCI Quirk: 1k I/O space IOBL_ADR fix on P64H2Daniel Yeisley
There's an existing quirk for the kernel to use 1k IO space granularity on the Intel P64H2. It turns out however that pci_setup_bridge() in drivers/pci/setup-bus.c reads in the IO base and limit address register masks it off to the nearest 4k, and writes it back. This causes the kernel to be on 1k boundaries and the hardware to be 4k aligned. The patch below fixes the problem.

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.
