2009-07-03parisc: ensure broadcast tlb purge runs single threadedHelge Deller3-19/+30
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. Signed-off-by: Helge Deller <deller@gmx.de> [edited to use spin_lock_irqsave on UP as well since we'd been locking there all this time anyway, --kyle] Signed-off-by: Kyle McMartin <kyle@mcmartin.ca>
2009-07-03parisc: fix "delay!" timer handlingGrant Grundler1-35/+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).

I think I have it right but recognize I might not. TODO: I wanted to use "do_div()" in order to get both remainder and value back with one division op. That should help with the latency alot but can be applied seperately from this patch. thanks, grant

2009-07-03parisc: fix ldcw inline assemblerHelge Deller1-2/+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.

2009-06-22Blackfin: unify memory map headersMike Frysinger16-350/+145
Many aspects of the Blackfin memory map is exactly the same across all variants. Rather than copy and paste all of these duplicated values in each header, unify all of these into the common Blackfin memory map header file.

2009-06-22Blackfin: stick the CPU name into boot image nameRobin Getz1-1/+1
Rather than use "Linux" in the boot image name (as this is redundant -- the image type is already set to "linux"), use the CPU name. This makes it fairly obvious when a wrong image is accidentally booted. Otherwise there is no kernel output and you waste time scratching your head wondering wtf just happened.

2009-06-22Blackfin: decouple unrelated cache settings to get exact behaviorJie Zhang11-81/+176
The current cache options don't really represent the hardware features. They end up setting different aspects of the hardware so that the end result is to turn on/off the cache. Unfortunately, when we hit cache problems with the hardware, it's difficult to test different settings to root cause the problem. The current settings also don't cleanly allow for different caching behaviors with different regions of memory. So split the configure options such that they properly reflect the settings that are applied to the hardware.

2009-06-22Blackfin: fix accidental reset in some boot modesSonic Zhang1-1/+2
We read the SWRST (Software Reset) register to get at the last reset state, and then we may configure the DOUBLE_FAULT bit to control behavior when a double fault occurs. But if the lower bits of the register is already set (like UART boot mode on a BF54x), we inadvertently make the system reset by writing to the SYSTEM_RESET field at the same time. So make sure the lower 4 bits are always cleared. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-06-22Blackfin: redo handling of bad irqsMike Frysinger1-42/+11
With the common IRQ code initializing much more of the irq_desc state, we can't blindly initialize it ourselves to the local bad_irq state. If we do, we end up wrongly clobbering many fields. So punt most of the bad irq code as the common layers will handle the default state, and simply call handle_bad_irq() directly when the IRQ we are processing is invalid.

pm_idle is used by infrastructure (eg, cpuidle) which expects architectures to call it in a certain way. Arrange for ARM to follow x86's lead on this and call pm_idle() with interrupts already disabled. However, we expect pm_idle() to enable interrupts before it returns.
