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.

- 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: David S. Peterson

- 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: David S. Peterson

- 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.Signed-off-by: David S. Peterson

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?

them.Signed-off-by: David S. Peterson
