2005-11-17[PARISC] Make superio.c initialize before any driver needs itKyle McMartin
Convert superio_init to use PCI_FIXUP_FINAL as ohci_pci being called before superio_probe really makes a mess. superio_init will then fail to register irq 20 (the "SuperIO" irq) and BUG() because ohci_pci has stolen it before superio_fixup_irq can be moved USB to irq 1.

2005-11-17[PARISC] Always spinlock tlb flush operations to ensure preempt safetyMatthew Wilcox
Since taking a spinlock disables preempt, and we need to spinlock tlb flush on SMP for N class, we might as well just spinlock on uniprocessor machines too. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

2005-11-17[PARISC] Define port->timeout to fix a long msleep in mux.cRyan Bradetich
This commit is in response to a bug reported by Vesa on the irc channel a couple of weeks ago. The bug was that the console would apparently hang (not return) while using the mux console. The root cause of this bug is that bash (with readline support) makes a call to the tcsetattr() glibc function with the argument TCSADRAIN. This causes the serial core in the kernel use the uart_wait_until_sent() to be called. This function verifies the mux transmit queue is empty or calls the msleep_interruptable() with a calculated timeout value that is dependant upon the port->timeout variable. The real problem here is that the port->timeout was not defined so it was defaulted to 0 and the timeout calculation performs the following calculation: char_time = (port->timeout - HZ/50) / port->fifosize; where char_time is an unsigned long. Since the serial Mux does not use interrupts, the msleep_interruptable() function waits until the timeout has been reached ... and when the port->timeout < HZ/50 this timeout will be a long time. (I have validated that the console will eventually return ... but it takes quite a while for this to happen). This patch simply sets the port->timeout on the Mux to HZ/50 to avoid this long timeout period.

2005-11-17[PARISC] Fix our spinlock implementationJames Bottomley
We actually have two separate bad bugs 1. The read_lock implementation spins with disabled interrupts. This is completely wrong 2. Our spin_lock_irqsave should check to see if interrupts were enabled before the call and re-enable interrupts around the inner spin loop. The problem is that if we spin with interrupts off, we can't receive IPIs. This has resulted in a bug where SMP machines suddenly spit smp_call_function timeout messages and hang. The scenario I've caught is CPU0 does a flush_tlb_all holding the vmlist_lock for write. CPU1 tries a cat of /proc/meminfo which tries to acquire vmlist_lock for read CPU1 is now spinning with interrupts disabled CPU0 tries to execute a smp_call_function to flush the local tlb caches This is now a deadlock because CPU1 is spinning with interrupts disabled and can never receive the IPI Signed-off-by: James Bottomley <jejb@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

2005-11-17[PARISC] Add IRQ affinitiesJames Bottomley
This really only adds them for the machines I can check SMP on, which is CPU interrupts and IOSAPIC (so not any of the GSC based machines). With this patch, irqbalanced can be used to maintain irq balancing. Unfortunately, irqbalanced is a bit x86 centric, so it doesn't do an incredibly good job, but it does work.

2005-11-17[PARISC] Fix uniprocessor build by dummying smp_send_all_nop()Kyle McMartin

2005-11-17[PARISC] Fix our interrupts not to use smp_call_functionJames Bottomley
Fix our interrupts not to use smp_call_function On K and D class smp, the generic code calls this under an irq spinlock, which causes the WARN_ON() message in smp_call_function() (and is also illegal because it could deadlock).

2005-11-17[PARISC] Disable nesting of interruptsGrant Grundler
Disable nesting of interrupts - still has holes The offending sequence starts out like this: 1) take external interrupt 2) set_eiem() to only allow TIMER_IRQ; local interrupts still disabled 3) read the EIRR to get a "list" of pending interrupts 4) clear EIRR of pending interrupts we intend to handle 5) call __do_IRQ() to handle IRQ. 6) handle_IRQ_event() enables local interrupts (I-Bit) 7) take a timer interrupt 8) read EIRR to get a new list of pending interrupts 9) clear EIRR of pending interrupts we just read 10) handle pending interrupts found in (8) 11) set_eiem(cpu_eiem) and return [ TROUBLE! all enabled CPU IRQs are unmasked. } 12) handle remaining interrupts pending from (3) e.g. call __do_IRQ() -> handle_IRQ_event()..etc [ TROUBLE! call to handle_IRQ_event() can now enable *any* IRQ. } 13) set_eiem(cpu_eiem) and return The problem is we now get into ugly race conditions with Timer and IPI interrupts at this point. I'm not exactly sure what happens when things go wrong (perhaps nest calls to IPI or timer interrupt?). But I'm certain it's not good. This sequence will break sooner if (10) would accidentally leave interrupts enabled. I'm pretty sure the right answer is now to make cpu_eiem a per CPU variable since all external interrupts on parisc are per CPU. This means we will NOT need to send an IPI to every CPU in the system when enabling or disabling an IRQ since only one CPU needs to change it's EIEM.

2005-11-17[PARISC] Make sure timer and IPI execute with interrupts disabledJames Bottomley
Fix a longstanding smp bug The problem is that both the timer and ipi interrupts are being called with interrupts enabled, which isn't what anyone is expecting. The IPI issue has just started to show up by causing a BUG_ON in the slab debugging code. The timer issue never shows up because there's an eiem work around in our irq.c The fix is to label both these as SA_INTERRUPT which causes the generic irq code not to enable interrupts. I also suspect the smp_call_function timeouts we're seeing might be connected with the fact that we disable IPIs when handling any other type of interrupt. I've put a WARN_ON in the code for executing smp_call_function() with IPIs disabled. Signed-off-by: James Bottomley <jejb@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>

2005-11-17[PATCH] x86: fix sigaddset() inline asm memory constraintConstantine Gavrilov
Due to incomplete memory constraints, gcc would miscompile code with sigaddset on i386 if sig arg was const. A quote form Jakub to make the issue clear: "You need either __asm__("btsl %1,%0" : "+m"(*set) : "Ir"(_sig-1) : "cc"); or __asm__("btsl %1,%0" : "=m"(*set) : "Ir"(_sig-1), "m"(*set) : "cc"); because the btsl instruction doesn't just set the memory to some value, but needs to read its previous content as well. If you don't tell that fact to GCC, GCC is of course free to optimize as if the asm was just setting the value and not depended on the previous value."
