* UBIFS: set write-buffer timout to 3-5 secondsArtem Bityutskiy2009-07-052-15/+7
| | | | | | | This patch cleans up write-buffer timeout initialization and sets it to 3-5 interval. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
* UBIFS: slightly optimize write-buffer timer usageArtem Bityutskiy2009-07-053-12/+9
| | | | | | | | | | | | | | | | | | | This patch adds the following minor optimization: 1. If write-buffer does not use the timer, indicate it with the wbuf->no_timer variable, instead of using the wbuf->softlimit variable. This is better because wbuf->softlimit is of ktime_t type, and the ktime_to_ns function contains 64-bit multiplication. 2. Do not call the 'hrtimer_cancel()' function for write-buffers which do not use timers. 3. Do not cancel the timer in 'ubifs_put_super()' because the synchronization function does this. This patch also removes a confusing comment. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

* video: sm501fb: Early initialization of mm_lock mutex.Paul Mundt2009-07-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Commit 537a1bf059fa312355696fa6db80726e655e7f17 (fbdev: add mutex for fb_mmap locking) introduces a ->mm_lock mutex for protecting smem assignments. Unfortunately in the case of sm501fb these happen quite early in the initialization code, well before the mutex_init() that takes place in register_framebuffer(), leading to: Badness at kernel/mutex.c:207 Pid : 1, Comm: swapper CPU : 0 Not tainted (2.6.31-rc1-00284-g529ba0d-dirty #2273) PC is at __mutex_lock_slowpath+0x72/0x1bc PR is at __mutex_lock_slowpath+0x66/0x1bc ... matroxfb appears to have the same issue and has solved it with an early mutex_init(), so we do the same for sm501fb.

| | | | | | | | | | | | | | | | | | | | | | | | The TLB flushing functions on hppa, which causes PxTLB broadcasts on the system bus, needs to be protected by irq-safe spinlocks to avoid irq handlers to deadlock the kernel. The deadlocks only happened during I/O intensive loads and triggered pretty seldom, which is why this bug went so long unnoticed.

| * parisc: fix "delay!" timer handlingGrant Grundler2009-07-031-35/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rewrote timer_interrupt() to properly handle the "delayed!" case. If we used floating point math to compute the number of ticks that had elapsed since the last timer interrupt, it could take up to 12K cycles (emperical!) to handle the interrupt. Existing code assumed it would never take more than 8k cycles. We end up programming Interval Timer to a value less than "current" cycle counter. Thus have to wait until Interval Timer "wrapped" and would then get the "delayed!" printk that I moved below. Since we don't really know what the upper limit is, I prefer to read CR16 again after we've programmed it to make sure we won't have to wait for CR16 to wrap. Further, the printk was between reading CR16 (cycle couner) and writing CR16 (the interval timer). This would cause us to continue to set the interval timer to a value that was "behind" the cycle counter. Rinse and repeat. So no printk's between reading CR16 and setting next interval timer. Tested on A500 (550 Mhz PA8600).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alex Chiang asked me why PARISC was calling pci_bus_add_devices() and pci_bus_assign_resources() in the opposite order from everyone else. No reason and I couldn't see any data dependency. Patch below applies cleanly to 2.6.30-rc2. Later, I suspected the code worked only because no drivers would be loaded/ready until much later in the system initialization sequence. Tested "LBA" code on J6000 (32-bit) and A500 (64-bit SMP) with 2.6.30-rc2. Not tested with any Dino controllers. Not tested with PCI-PCI Bridge (TBD).

| * parisc: fix ldcw inline assemblerHelge Deller2009-07-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two reasons to expose the memory *a in the asm: 1) To prevent the compiler from discarding a preceeding write to *a, and 2) to prevent it from caching *a in a register over the asm. The change has had a few days testing with a SMP build of 2.6.22.19 running on a rp3440. This patch is about the correctness of the __ldcw() macro itself. The use of the macro should be confined to small inline functions to try to limit the effect of clobbering memory on GCC's optimization of loads and stores.

Instead, the value from current_cred() should be passed directly to dentry_open() as one of its arguments, rather than being cached in a variable. Possibly fh_verify() should return the creds to use.

So we'll switch to use the right register defines in this situation by checking for WANT_COMPAT_REG_H and use the right defines of ELF_CORE_COPY_REGS and ELF_CORE_COPY_TASK_REGS.

For example in my case PCI host is on irq 0 and IPSEC on irq 3. The current code: - store in dev->irq that IPSEC irq is 3 + 2 - do a set_irq 0->3 on PCI host But now IPSEC irq is not routed anymore to the mips code and dev->irq is wrong. This causes a problem described in [1]. This patch tries to solve the problem by making set_irq configure the device we want to take the irq on the shared irq0. The previous example becomes: - store in dev->irq that IPSEC irq is 3 + 2 - do a set_irq 0->3 on PCI host: - irq 3 is already taken by IPSEC. do a set_irq 3->0 on IPSEC I also added some code to print the irq configuration after irq setup to allow easier debugging. And I add extra checking in ssb_mips_irq to report device without irq or device with not routed irq.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is to move the gcmp_probe call to before the use of and selection of the smp_ops functions. This allows malta with 1004K to work. Signed-off-by: Tim Anderson <tanderson@mvista.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the CMP support was added before, this mostly correct compile problems but adds a platform specific translation for the interrupt number based on cpu number.
