We must clear down all currently pending IRQs before servicing any IRQ on the chip. This prevents immediate recursion into the interrupt handling paths when we service the first IRQ.

This didn't follow the LDM model correctly. The SA1111 is always a device on the root bus.

This cset updates the SA1111 core, PCMCIA, OHCI and keyboard drivers, allowing them to take advantage of the Linux device manager code; this implements initial suspend/resume support for the SA1111 in the core. Many existing drivers currently rely on the old PM-based interface for suspend/resume support.

Two bugs here: 1) The return value of strchr("foo",0) should be the start address of "foo" + 3, not NULL. 2) Since the second argument for strchr() is defined as an int, some characters such as 'é' might validly end up to be the value -23 due to signedness issues. Corectly handle those.

The return value from ptrace_set_bit() is never used. This cset makes it a void function.

This removes some minor differences between Linus' tree and the main ARM tree; comment clarification and some weird formatting.

This keeps ARM in line with the continued transition to the input layer.

Hi, I believe the comment in the nwfpe fpopcodes is slightly wrong - although a 2nd pair of eyes on this would be a good idea.

Hi, For reasons of great complexity I found out the hard way that the kernel must (and does) zero the pad sections in the stat structures. Here is a comment that states this for the next person who needs to know.

This is the smptimers patch plus the removal of old BHs and a rewrite of task-queue handling. Basically with the removal of TIMER_BH i think the time is right to get rid of old BHs forever, and to do a massive cleanup of all related fields. The following five basic 'execution context' abstractions are supported by the kernel: - hardirq - softirq - tasklet - keventd-driven task-queues - process contexts I've done the following cleanups/simplifications to task-queues: - removed the ability to define your own task-queue, what can be done is to schedule_task() a given task to keventd, and to flush all pending tasks. This is actually a quite easy transition, since 90% of all task-queue users in the kernel used BH_IMMEDIATE - which is very similar in functionality to keventd. I believe task-queues should not be removed from the kernel altogether. It's true that they were written as a candidate replacement for BHs originally, but they do make sense in a different way: it's perhaps the easiest interface to do deferred processing from IRQ context, in performance-uncritical code areas. They are easier to use than tasklets. code that cares about performance should convert to tasklets - as the timer code and the serial subsystem has done already. For extreme performance softirqs should be used - the net subsystem does this. and we can do this for 2.6 - there are only a couple of areas left after fixing all the BH_IMMEDIATE places. i have moved all the taskqueue handling code into kernel/context.c, and only kept the basic 'queue a task' definitions in include/linux/tqueue.h. I've converted three of the most commonly used BH_IMMEDIATE users: tty_io.c, floppy.c and random.c. [random.c might need more thought though.] i've also cleaned up kernel/timer.c over that of the stock smptimers patch: privatized the timer-vec definitions (nothing needs it, init_timer() used it mistakenly) and cleaned up the code. Plus i've moved some code around that does not belong into timer.c, and within timer.c i've organized data and functions along functionality and further separated the base timer code from the NTP bits. net_bh_lock: i have removed it, since it would synchronize to nothing. The old protocol handlers should still run on UP, and on SMP the kernel prints a warning upon use. Alexey, is this approach fine with you? scalable timers: i've further improved the patch ported to 2.5 by wli and Dipankar. There is only one pending issue i can see, the question of whether to migrate timers in mod_timer() or not. I'm quite convinced that they should be migrated, but i might be wrong. It's a 10 lines change to switch between migrating and non-migrating timers, we can do performance tests later on. The current, more complex migration code is pretty fast and has been stable under extremely high networking loads in the past 2 years, so we can immediately switch to the simpler variant if someone proves it improves performance. (I'd say if non-migrating timers improve Apache performance on one of the bigger NUMA boxes then the point is proven, no further though will be needed.)

Avoid racing on signal delivery with thread signal blocking in thread groups. The method to do this is to eliminate the per-thread sigmask_lock, and use the per-group (per 'process') siglock for all signal related activities. This immensely simplified some of the locking interactions within signal.c, and enabled the fixing of the above category of signal delivery races. This became possible due to the former thread-signal patch, which made siglock an irq-safe thing. (it used to be a process-context-only spinlock.) And this is even a speedup for non-threaded applications: only one lock is used. I fixed all places within the kernel except the non-x86 arch sections. Even for them the transition is very straightforward, in almost every case the following is sufficient in arch/*/kernel/signal.c: :1,$s/->sigmask_lock/->sig->siglock/g

This fixes the bug reported by David Mosberger, force_sig_info() dropped the siginfo structure, which broke things like SIGFPU or alignment-error exceptions. This bug was introduced by the threading signal changes. (The patch also fixes signal declaration whitespaces in sched.h.)
