Somewhere in the rewrite of the work queues my cleanup of SAK handling got broken. Maybe I didn't retest it properly or possibly the API was changing so fast I missed something. Regardless currently triggering a SAK now generates an ugly BUG_ON and kills the kernel. Thanks to Alexey Dobriyan <adobriyan@openvz.org> for spotting this. This modifies the use of SAK_work to initialize it when the data structure it resides in is initialized, and to simply call schedule_work when we need to generate a SAK. I update both data structures that have a SAK_work member for consistency. All of the old PREPARE_WORK calls that are now gone. If we call schedule_work again before it has processed it has generated the first SAK it will simply ignore the duplicate schedule_work request. Signed-off-by:

This reverts commit eb3dfb0c. It causes some strange Gnome problem with dbus-daemon getting stuck, so we'll revert it until that problem is understood. Reported by both walt and Greg KH, who both independently git-bisected the problem to this commit. Andreas is looking at it. Reported-by:

This reverts some bogosity from the dynamic command-line changes made on sparc32 and sparc64. Drivers such as drivers/sbus/char/openprom.c reference saved_command_line, and can be modular. The boot_command_line is __initdata, yet the dynamic command-line changes add modular exports of that symbol, obviously wrong. Signed-off-by:David S. Miller <davem@davemloft.net>

NF_CT_STAT_INC assumes rcu_read_lock in nf_hook_slow disables preemption as well, making it legal to use __get_cpu_var without disabling preemption manually. The assumption is not correct anymore with preemptable RCU, additionally we need to protect against softirqs when not holding nf_conntrack_lock. Add NF_CT_STAT_INC_ATOMIC macro, which disables local softirqs, and use where necessary. Signed-off-by:

Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by:
