The problem comes when ks0108/cfag12864b are built-in and no parallel port is present. ks0108_init() is called first, as it should be, but fails to load (as there is no parallel port to use). After that, cfag12864b_init() gets called, without knowing anything about ks0108 failed, and calls ks0108_writecontrol(), which dereferences an uninitialized pointer. Init order is OK, I think. The problem is how to stop cfag12864b_init() being called if ks0108 failed to load. modprobe does it for us, but, how when built-in? Signed-off-by:

There is no prompt for CONFIG_STACKTRACE, so FAULT_INJECTION cannot be selected without LOCKDEP enabled. (found by Paolo 'Blaisorblade' Giarrusso) In order to fix such broken Kconfig dependency, this patch splits up the stacktrace filter support for fault injection by new Kconfig option, which enables to use fault injection on the architecture which doesn't have general stacktrace support.

This patch lists all active probes in the system by scanning through kprobe_table[]. It takes care of aggregate handlers and prints the type of the probe. Letter "k" for kprobes, "j" for jprobes, "r" for kretprobes. It also lists address of the instruction,its symbolic name(function name + offset) and the module name. One can access this file through /sys/kernel/debug/kprobes/list. Output looks like this ===================== llm40:~/a # cat /sys/kernel/debug/kprobes/list c0169ae3 r sys_read+0x0 c0169ae3 k sys_read+0x0 c01694c8 k vfs_write+0x0 c0167d20 r sys_open+0x0 f8e658a6 k reiserfs_delete_inode+0x0 reiserfs c0120f4a k do_fork+0x0 c0120f4a j do_fork+0x0 c0169b4a r sys_write+0x0 c0169b4a k sys_write+0x0 c0169622 r vfs_read+0x0 ================================= [akpm@linux-foundation.org: cleanup] [ananth@in.ibm.com: sparc build fix] Signed-off-by:

Andrew noticed that unlocking the page before submitting all buffers for writeout could cause problems if the IO completes before we've finished messing around with the page buffers, and they subsequently get freed. Even if there were no bug, it is a good idea to bring the error case into line with the common case here. Signed-off-by:

The current ipc shared memory code runs into several problems because it does not quite use files like the rest of the kernel. With the option of backing ipc shared memory with either hugetlbfs or ordinary shared memory the problems got worse. With the added support for ipc namespaces things behaved so unexpected that we now have several bad namespace reference counting bugs when using what appears at first glance to be a reasonable idiom. So to attack these problems and hopefully make the code more maintainable this patch simply uses the files provided by other parts of the kernel and builds it's own files out of them. The shm files are allocated in do_shmat and freed when their reference count drops to zero with their last unmap. The file and vm operations that we don't want to implement or we don't implement completely we just delegate to the operations of our backing file. This means that we now get an accurate shm_nattch count for we have a hugetlbfs inode for backing store, and the shm accounting of last attach and last detach time work as well. This means that getting a reference to the ipc namespace when we create the file and dropping the referenece in the release method is now safe and correct. This means we no longer need a special case for clearing VM_MAYWRITE as our file descriptor now only has write permissions when we have requested write access when calling shmat. Although VM_SHARED is now cleared as well which I believe is harmless and is mostly likely a minor bug fix. By using the same set of operations for both the hugetlb case and regular shared memory case shmdt is not simplified and made slightly more correct as now the test "vma->vm_ops == &shm_vm_ops" is 100% accurate in spotting all shared memory regions generated from sysvipc shared memory.

The alien cache is a per cpu per node array allocated for every slab on the system. Currently we size this array for all nodes that the kernel does support. For IA64 this is 1024 nodes. So we allocate an array with 1024 objects even if we only boot a system with 4 nodes. This patch uses "nr_node_ids" to determine the number of possible nodes supported by a hardware configuration and only allocates an alien cache sized for possible nodes. The initialization of nr_node_ids occurred too late relative to the bootstrap of the slab allocator and so I moved the setup_nr_node_ids() into free_area_init_nodes(). Signed-off-by:

We frequently need the maximum number of possible processors in order to allocate arrays for all processors. So far this was done using highest_possible_processor_id(). However, we do need the number of processors not the highest id. Moreover the number was so far dynamically calculated on each invokation. The number of possible processors does not change when the system is running. We can therefore calculate that number once. Signed-off-by:

highest_possible_node_id() is currently used to calculate the last possible node idso that the network subsystem can figure out how to size per node arrays. I think having the ability to determine the maximum amount of nodes in a system at runtime is useful but then we should name this entry correspondingly, it should return the number of node_ids, and the the value needs to be setup only once on bootup. The node_possible_map does not change after bootup. This patch introduces nr_node_ids and replaces the use of highest_possible_node_id(). nr_node_ids is calculated on bootup when the page allocators pagesets are initialized.

Mark Brown authored
This patch provides code paths which allow the natsemi driver to use the external MII port on the chip but ignore any PHYs that may be attached to it. The link state will be left as it was when the driver started and can be configured via ethtool. Any PHYs that are present can be accessed via the MII ioctl()s. This is useful for systems where the device is connected without a PHY or where either information or actions outside the scope of the driver are required in order to use the PHYs. Signed-Off-By:
