* sparc64: Fix lost interrupts on sun4u.David S. Miller2009-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based upon a report by Meelis Roos. Sparc64 SBUS and PCI controllers use a combination of IMAP and ICLR registers to manage device interrupts. The IMAP register contains the "valid" enable bit as well as CPU targetting information. Whereas the ICLR register is written with zero at the end of handling an interrupt to reset the state machine for that interrupt to IDLE so it can be sent again. For PCI slot and SBUS slot devices we can have multiple interrupts sharing the same IMAP register. There are individual ICLR registers but only one IMAP register for managing those. We represent each shared case with individual virtual IRQs so the generic IRQ layer thinks there is only one user of the IRQ instance. In such shared IMAP cases this is wrong, so if there are multiple active users then a free_irq() call will prematurely turn off the interrupt by clearing the Valid bit in the IMAP register even though there are other active users. Fix this by simply doing nothing in sun4u_disable_irq() and checking IRQF_DISABLED during IRQ dispatch. This situation doesn't exist in the hypervisor sun4v cases, so I left those alone.

* sparc64: On non-Niagara, need to touch NMI watchdog in NOHZ mode.David S. Miller2009-02-03
| | | | | | | | | | | | | | | | | | | | | When we're idling in NOHZ mode, timer interrupts are not running. Evidence of processing timer interrupts is what the NMI watchdog uses to determine if the CPU is stuck. On Niagara, we'll yield the cpu. This will make the cpu, at worst, hang out in the hypervisor until an interrupt arrives. This will prevent the NMI watchdog timer from firing. However on non-Niagara we just loop executing instructions which will cause the NMI watchdog to keep firing. It won't see timer interrupts happening so it will think the cpu is stuck. Fix this by touching the NMI watchdog in the cpu idle loop on non-Niagara machines. Signed-off-by: David S. Miller <davem@davemloft.net>

The fix is to force a few constants to ULL. The following stands out from the rest: +#define PSYCHO_IOMMU_TAG_VPAGE 0x7ffffULL +#define PSYCHO_IOMMU_DATA_PPAGE 0xfffffffULL They were needed otherwise the expression: (data_val & PSYCHO_IOMMU_DATA_PPAGE) << IOMMU_PAGE_SHIFT) were promoted to a unsigned long and not a unsigned long long as expected. I tried the alternative solution and made IOMMU_PAGE_SHIFT an ULL but that did not help. The only way gcc would make this expression an unsigned long long was to define PSYCHO_IOMMU_DATA_PPAGE as ULL. The alternative to add a cast was not considered a valid solution. We had this issue in two places and this were the only places the above two constants are used. A small coding style diff sneaked in too.

Update types.h so we use unsigned long long for u64 and fix all warnings in sparc64 code. Tested with an allnoconfig, defconfig and allmodconfig builds.

| * | cpumask: centralize cpu_online_map and cpu_possible_mapRusty Russell2008-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup Each SMP arch defines these themselves. Move them to a central location. Twists: 1) Some archs (m32, parisc, s390) set possible_map to all 1, so we add a CONFIG_INIT_ALL_POSSIBLE for this rather than break them. 2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'. Those archs simply have phys_cpu_present_map replaced everywhere. 3) Alpha defined cpu_possible_map to cpu_present_map; this is tricky so I just manipulate them both in sync. 4) IA64, cris and m32r have gratuitous 'extern cpumask_t cpu_possible_map' declarations.

* | sparc: unify sections.hSam Ravnborg2008-12-27
| | | | | | | | | | | | | | | | | | | | | | | | While doing this use standard names for start/end so we could use definitions straight from asm-generic for all the typical symbols. This also allowed us to drop the use of PROVIDE in the linker script so sprc is less non-standard on this area. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

* | sparc: use .data.init_task section for init_thread_unionSam Ravnborg2008-12-27
| | | | | | | | | | | | | | | | | | | | | | Use a dedicated aligned section for the init_thread_union variable and declare this section in vmlinux.lds. This align sparc with most other architectures. Eventually this allow the init_task bits to be unified across all architectures. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
