Bitmap functions for the minix filesystem and the ext2 filesystem except ext2_set_bit_atomic() and ext2_clear_bit_atomic() do not require the atomic guarantees. But these are defined by using atomic bit operations on several architectures. (cris, frv, h8300, ia64, m32r, m68k, m68knommu, mips, s390, sh, sh64, sparc, sparc64, v850, and xtensa) This patch switches to non atomic bit operation. Signed-off-by:

- Add entries to MAINTAINERS list for EDAC-E752X, EDAC-E7XXX, and EDAC-R82600 chipset drivers - Fix MAINTAINERS entry for EDAC-CORE so it uses tabs rather than spaces to indent. This is consistent with how the other entries are formatted. Signed-off-by:

- Fix code so we always hold mem_ctls_mutex while we are stepping through the list of mem_ctl_info structures. Otherwise bad things may happen if one task is stepping through the list while another task is modifying it. We may eventually want to use reference counting to manage the mem_ctl_info structures. In the meantime we may as well fix this bug. - Don't disable interrupts while we are walking the list of mem_ctl_info structures in check_mc_devices(). This is unnecessary. Signed-off-by:

- After we unregister a kobject, wait for our kobject release method to call complete(). This causes us to wait until the kobject reference count reaches 0. Otherwise, a task accessing the EDAC sysfs interface can hold the reference count above 0 until after the EDAC module has been unloaded. When the reference count finally drops to 0, this will result in an attempt to call our release method inside the EDAC module after the module has already been unloaded. This isn't the best fix, since a process can get stuck sleeping forever uninterruptibly if the user does the following: rmmod my_module < /sys/my_sysfs/file I'll go back and implement a better fix later. However this should be ok for now. - Call edac_remove_sysfs_mci_device() from edac_mc_del_mc() rather than from edac_mc_free(). Since edac_mc_add_mc() calls edac_create_sysfs_mci_device(), edac_mc_del_mc() should call edac_remove_sysfs_mci_device(). Signed-off-by: -

- Remove calls to kobject_init(). These are unnecessary because kobject_register() calls kobject_init(). - Remove extra calls to kobject_put(). When we call kobject_unregister(), this releases our reference to the kobject. The extra calls to kobject_put() may cause the reference count to drop to 0 while a kobject is still in use.

This is part 1 of a 2-part patch set. The code changes are split into two parts to make the patches more readable. Move complete_mc_list_del() and del_mc_from_global_list() so we can call del_mc_from_global_list() from edac_mc_add_mc() without forward declarations. Perhaps using forward declarations would be better? I'm doing things this way because the rest of the code is missing them. Signed-off-by:

- Add ctl_dev field to "struct e752x_dev_info". Then we can eliminate ugly switch statement from e752x_probe1(). - Remove code from e752x_probe1() that clears initial PCI bus parity errors. The core EDAC module already does this. Signed-off-by:

And: Tilman Schmidt <tilman@imap.cc> This patch adds the procfs interface to the gigaset module. The procfs interface provides access to status information and statistics about the Gigaset devices. If the drivers are built with the debugging option it also allows to change the amount of debugging output on the fly. Signed-off-by:
