Use the new typedef for interrupt handler function pointers rather than actually spelling out the full thing each time.

2006-10-08[PATCH] sparc32 rwlock fixAl Viro2-1/+23
read_trylock() is broken on sparc32 (doesn't build and didn't work right, actually). Proposed fix: - make "writer holds lock" distinguishable from "reader tries to grab lock" - have __raw_read_trylock() try to acquire the mutex (in LSB of lock), terminating spin if we see that there's writer holding it. Then do the rest as we do in read_lock(). Thanks to Ingo for discussion... Signed-off-by: Al Viro <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2006-10-08[PATCH] x86_64 irq: Allocate a vector across all cpus for genapic_flat.Eric W. Biederman3-48/+115
The problem we can't take advantage of lowest priority delivery mode if the vectors are allocated for only one cpu at a time. Nor can we work around hardware that assumes lowest priority delivery mode is always used with several cpus. So this patch introduces the concept of a vector_allocation_domain. A set of cpus that will receive an irq on the same vector. Currently the code for implementing this is placed in the genapic structure so we can vary this depending on how we are using the io_apics. This allows us to restore the previous behaviour of genapic_flat without removing the benefits of having separate vector allocation for large machines. This should also fix the problem report where a hyperthreaded cpu was receving the irq on the wrong hyperthread when in logical delivery mode because the previous behaviour is restored. This patch properly records our allocation of the first 16 irqs to the first 16 available vectors on all cpus. This should be fine but it may run into problems with multiple interrupts at the same interrupt level. Except for some badly maintained comments in the code and the behaviour of the interrupt allocator I have no real understanding of that problem. Signed-off-by: Eric W.

2006-10-08[PATCH] i386/x86_64: Remove global IO_APIC_VECTOREric W. Biederman2-10/+10
Which vector an irq is assigned to now varies dynamically and is not needed outside of io_apic.c. So remove the possibility of accessing the information outside of io_apic.c and remove the silly macro that makes looking for users of irq_vector difficult. The fact this compiles ensures there aren't any more pieces of the old CONFIG_PCI_MSI weirdness that I failed to remove. Signed-off-by: Eric W. Biederman <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2006-10-08[PATCH] i386/x86_64: FIX pci_enable_irq to set dev->irq to the irq numberEric W. Biederman1-4/+0
In commit ace80ab796ae30d2c9ee8a84ab6f608a61f8b87b I removed the weird logic that used the vector number as the irq number when MSI was defined. However pci_enable_irq was using a different test in the io_apic_assign_irqs path and I missed it :( This patch removes the wrong code so no one hits this problem. This code is only active when a specific set of boot command line parameters is specified which likely explains why no one has notices this earlier. Signed-off-by: Eric W.
