* [S390] Poison init section before freeing it.Heiko Carstens2006-12-08
| | | | | | | | | The data patterns should allow us to easily tell if somebody accesses initdata/code after it was freed. Same code as on various other architectures. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

* [S390] Virtual memmap for s390.Heiko Carstens2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Virtual memmap support for s390. Inspired by the ia64 implementation. Unlike ia64 we need a mechanism which allows us to dynamically attach shared memory regions. These memory regions are accessed via the dcss device driver. dcss implements the 'direct_access' operation, which requires struct pages for every single shared page. Therefore this implementation provides an interface to attach/detach shared memory: int add_shared_memory(unsigned long start, unsigned long size); int remove_shared_memory(unsigned long start, unsigned long size); The purpose of the add_shared_memory function is to add the given memory range to the 1:1 mapping and to make sure that the corresponding range in the vmemmap is backed with physical pages. It also initialises the new struct pages. remove_shared_memory in turn only invalidates the page table entries in the 1:1 mapping. The page tables and the memory used for struct pages in the vmemmap are currently not freed. They will be reused when the next segment will be attached. Given that the maximum size of a shared memory region is 2GB and in addition all regions must reside below 2GB this is not too much of a restriction, but there is room for improvement.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates some bookkeeping for driver registering. It closely models what pci_register_driver() does. The main addition is that the owner of the driver is set, so we get a proper symlink for /sys/bus/ieee1394/driver/*/module. Also moves setting of name and bus type into nodemgr. Because of this, we can remove the EXPORT_SYMBOL for ieee1394_bus_type, since it's now only used in ieee1394.ko. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>

At the same time the knodemgrd slept uninterruptibly in bus_rescan_devices_helper. That's because driver_detach took the semaphore of the PCI device and bus_rescan_devices_helper wanted to take the semaphore of the FireWire host device's parent, which is the same semaphore. This was a regression since Linux 2.6.16, commit bf74ad5bc41727d5f2f1c6bedb2c1fac394de731, "Hold the device's parent's lock during probe and remove". The fix (or workaround) adds a dummy driver to the hpsb_host device. Now bus_rescan_devices_helper won't scan the host device anymore. This doesn't hurt since we have no drivers which will bind to these devices and it is unlikely that there will ever be such a driver. The dummy driver is befittingly presented as a representation of ieee1394 itself. Fixes: http://bugzilla.kernel.org/show_bug.cgi?id=6706 Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
