Now platform_device is being widely used on SoC processors where the peripherals are attached to the system bus, which is simple enough. However, silicon IPs for these SoCs are usually shared heavily across a family of processors, even products from different companies. This makes the original simple driver name based matching insufficient, or simply not straight-forward. Introduce a module id table for platform devices, and makes it clear that a platform driver is able to support some shared IP and handle slight differences across different platforms (by 'driver_data'). Module alias is handled automatically when a MODULE_DEVICE_TABLE() is defined. To not disturb the current platform drivers too much, the matched id entry is recorded and can be retrieved by platform_get_device_id(). Signed-off-by:

This patch moves bus->match out from driver_probe_device and does not hold device lock to check the match between a device and a driver. The idea has been verified by the commit 6cd49586, which leads to a faster boot. But the commit 6cd49586 has the following drawbacks: 1),only does the quick check in the path of __driver_attach->driver_probe_device, not in other paths; 2),for a matched device and driver, check the same match twice. It is a waste of cpu ,especially for some drivers with long device id table (eg. usb-storage driver). This patch adds a helper of driver_match_device to check the match in all paths, and testes the match only once. Signed-off-by:

sysfs_get_inode ultimately calls sysfs_count_nlink when the a directory inode is fectched. sysfs_count_nlink needs to be called under the sysfs_mutex to guard against the unlikely but possible scenario that the root directory is changing as we are counting the number entries in it, and just in general to be consistent.

These simple debug statments should be using dev_dbg() instead of accessing bus_id directly (or they should use device_name). As bus_id is going away, this patch is necessary. Acked-by:

With a sufficiently new compiler and binutils, code which wasn't previously generating .eh_frame sections has begun to. Certain architectures (powerpc, in this case) may generate unexpected relocation formats in response to this, preventing modules from loading. While the new relocation types should probably be handled, revert to the previous behaviour with regards to generation of .eh_frame sections. (This was reported against Fedora, which appears to be the only distro doing any building against gcc-4.4 at present: RH bz#486545.) Signed-off-by:

This patch fixes bug #12208: Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12208 Subject : uml is very slow on 2.6.28 host This turned out to be not a scheduler regression, but an already existing problem in ptrace being triggered by subtle scheduler changes. The problem is this: - task A is ptracing task B - task B stops on a trace event - task A is woken up and preempts task B - task A calls ptrace on task B, which does ptrace_check_attach() - this calls wait_task_inactive(), which sees that task B is still on the runq - task A goes to sleep for a jiffy - ... Since UML does lots of the above sequences, those jiffies quickly add up to make it slow as hell. This patch solves this by not rescheduling in read_unlock() after ptrace_stop() has woken up the tracer. Thanks to Oleg Nesterov and Ingo Molnar for the feedback. Signed-off-by:
