2009-09-24cpumask: arch_send_call_function_ipi_mask: mipsRusty Russell1-2/+2
We're weaning the core code off handing cpumask's around on-stack. This introduces arch_send_call_function_ipi_mask(), and by defining it, the old arch_send_call_function_ipi is defined by the core code. We also take the chance to wean the implementations off the obsolescent for_each_cpu_mask(): making send_ipi_mask take the pointer seemed the most natural way to ensure all implementations used for_each_cpu.

2009-08-15timekeeping: Increase granularity of read_persistent_clock()Martin Schwidefsky1-2/+3
The persistent clock of some architectures (e.g. s390) have a better granularity than seconds. To reduce the delta between the host clock and the guest clock in a virtualized system change the read_persistent_clock function to return a struct timespec.

2009-08-03MIPS: Simplify and correct interrupt handling for MSP4200Shane McDonald1-9/+1
The current interrupt handling code for the MSP4200 always masks an interrupt before acknowledging it. This is not required, as that will be handled by the level interrupt handler. This change simplifies the MSP4200 code to remove the masking in the ack routine, and makes sure that the minimum required operation is performed for masking and acking, rather than always both masking and acking the interrupt.

2009-08-03MIPS: MSP71xx: fix build failures on msp_irq_slp.cFlorian Fainelli1-2/+2
Trying to build MSP4200 VoIP defconfig also fails on msp_irq_slp.c with a non-existing reference to mask_slp_irq, which is in turn mask_msp_slp_irq. Passed that, we will also miss a comma when calling set_irq_chip_and_handler. This patch fixes both issues.

2008-12-13cpumask: centralize cpu_online_map and cpu_possible_mapRusty Russell1-3/+3
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.

2008-06-27PCI: remove unused arch pcibios_update_resource() functionsAdrian Bunk1-36/+0
Russell King did the following back in 2003: <-- snip --> [PCI] pci-9: Kill per-architecture pcibios_update_resource() Kill pcibios_update_resource(), replacing it with pci_update_resource(). pci_update_resource() uses pcibios_resource_to_bus() to convert a resource to a device BAR - the transformation should be exactly the same as the transformation used for the PCI bridges. pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to set the high 32-bits to anything non-zero - currently no architecture attempts to do something different. If anyone cares, please fix; I'm going to reflect current behaviour for the time being. Ivan pointed out the following architectures need to examine their pcibios_update_resource() implementation - they should make sure that this new implementation does the right thing. #warning's have been added where appropriate. ia64 mips mips64 This cset also includes a fix for the problem reported by AKPM where 64-bit arch compilers complain about the resource mask being placed in a u32. <-- snip --> This patch removes the unused pcibios_update_resource() functions the kernel gained since, from FRV, m68k, mips & sh architectures.

2007-05-07serial driver PMC MSP71xxMarc St-Jean1-0/+165
Serial driver patch for the PMC-Sierra MSP71xx devices. There are three different fixes: 1 Fix for DesignWare APB THRE errata: In brief, this is a non-standard 16550 in that the THRE interrupt will not re-assert itself simply by disabling and re-enabling the THRI bit in the IER, it is only re-enabled if a character is actually sent out. It appears that the "8250-uart-backup-timer.patch" in the "mm" tree also fixes it so we have dropped our initial workaround. This patch now needs to be applied on top of that "mm" patch. 2 Fix for Busy Detect on LCR write: The DesignWare APB UART has a feature which causes a new Busy Detect interrupt to be generated if it's busy when the LCR is written. This fix saves the value of the LCR and rewrites it after clearing the interrupt. 3 Workaround for interrupt/data concurrency issue: The SoC needs to ensure that writes that can cause interrupts to be cleared reach the UART before returning from the ISR. This fix reads a non-destructive register on the UART so the read transaction completion ensures the previously queued write transaction has also completed.
