Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: NRafael J.

set_irq_msi() currently connects an irq_desc to an msi_desc. The archs call it at some point in their setup routine, and then the generic code sets up the reverse mapping from the msi_desc back to the irq. set_irq_msi() should do both connections, making it the one and only call required to connect an irq with it's MSI desc and vice versa. The arch code MUST call set_irq_msi(), and it must do so only once it's sure it's not going to fail the irq allocation. Given that there's no need for the arch to return the irq anymore, the return value from the arch setup routine just becomes 0 for success and anything else for failure.

When removing set_native_irq I missed the fact that it was called in a couple of places that were compiled even when SMP support is disabled. And since the irq_desc[].affinity field only exists in SMP things broke. Thanks to Simon Arlott <simon@arlott.org> for spotting this. There are a couple of ways to fix this but the simplest one is to just remove the assignments. The affinity field is only used to display a value to the user, and nothing on either i386 or x86_64 reads it or depends on it being any particlua value, so skipping the assignment is safe. The assignment that is being removed is just for the initial affinity value before the user explicitly sets it. The irq_desc array initializes this field to CPU_MASK_ALL so the field is initialized to a reasonable value in the SMP case without being set. Signed-off-by: NEric W.

When the world was a simple and static place setting up irqs was easy. It sufficed to allocate a linux irq number and a find a free cpu vector we could receive that linux irq on. In those days it was a safe assumption that any allocated vector was actually in use so after one global pass through all of the vectors we would have none left. These days things are much more dynamic with interrupt controllers (in the form of MSI or MSI-X) appearing on plug in cards and linux irqs appearing and disappearing. As these irqs come and go vectors are allocated and freed, invalidating the ancient assumption that all allocated vectors stayed in use forever. So this patch modifies the vector allocator to walk through every possible vector before giving up, and to check to see if a vector is in use before assigning it. With these changes we stop leaking freed vectors and it becomes possible to allocate and free irq vectors all day long. This changed was modeled after the vector allocator on x86_64 where this limitation has already been removed. In essence we don't update the static variables that hold the position of the last vector we allocated until have successfully allocated another vector. This allows us to detect if we have completed one complete scan through all of the possible vectors. Acked-by: NAuke Kok <auke-jan.h.kok@intel.com> Signed-off-by: NEric W.

Add a way to disable the timer IRQ routing check via a boot option. The VMI timer code uses this to avoid triggering the pester Mingo code, which probes for some very unusual and broken motherboard routings. It fires 100% of the time when using a paravirtual delay mechanism instead of using a realtime delay, since there is no elapsed real time, and the 4 timer IRQs have not yet been delivered. In addition, it is entirely possible, though improbable, that this bug could surface on real hardware which picks a particularly bad time to enter SMM mode, causing a long latency during one of the timer IRQs. While here, make check_timer be __init.

Komuro reports that ISA interrupts do not work after a disable_irq(), causing some PCMCIA drivers to not work, with messages like eth0: Asix AX88190: io 0x300, irq 3, hw_addr xx:xx:xx:xx:xx:xx eth0: found link beat eth0: autonegotiation complete: 100baseT-FD selected eth0: interrupt(s) dropped! eth0: interrupt(s) dropped! eth0: interrupt(s) dropped! ... Linus Torvalds <torvalds@osdl.org> said: "Now, edge-triggered interrupts are a _lot_ harder to mask, because the Intel APIC is an unbelievable piece of sh*t, and has the edge-detect logic _before_ the mask logic, so if a edge happens _while_ the device is masked, you'll never ever see the edge ever again (unmasking will not cause a new edge, so you simply lost the interrupt). So when you "mask" an edge-triggered IRQ, you can't really mask it at all, because if you did that, you'd lose it forever if the IRQ comes in while you masked it. Instead, we're supposed to leave it active, and set a flag, and IF the IRQ comes in, we just remember it, and mask it at that point instead, and then on unmasking, we have to replay it by sending a self-IPI." This trivial patch solves the problem. Signed-off-by: NEric W.

It turns out msi_ops was simply not enough to abstract the architecture specific details of msi. So I have moved the resposibility of constructing the struct irq_chip to the architectures, and have two architecture specific functions arch_setup_msi_irq, and arch_teardown_msi_irq. For simple architectures those functions can do all of the work. For architectures with platform dependencies they can call into the appropriate platform code.

This patch implements two functions ht_create_irq and ht_destroy_irq for use by drivers. Several other functions are implemented as helpers for arch specific irq_chip handlers. The driver for the card I tested this on isn't yet ready to be merged. However this code is and hypertransport irqs are in use in a few other places in the kernel. Not that any of this will get merged before 2.6.19 Because the ipath-ht400 is slightly out of spec this code will need to be generalized to work there. I think all of the powerpc uses are for a plain interrupt controller in a chipset so support for native hypertransport devices is a little less interesting. However I think this is a half way decent model on how to separate arch specific and generic helper code, and I think this is a functional model of how to get the architecture dependencies out of the msi code.
