* cpumask: make irq_set_affinity() take a const struct cpumaskRusty Russell2008-12-131-2/+2
| | | | | | | | | | | | | | | | | | | | | | | Impact: change existing irq_chip API Not much point with gentle transition here: the struct irq_chip's setaffinity method signature needs to change. Fortunately, not widely used code, but hits a few architectures. Note: In irq_select_affinity() I save a temporary in by mangling irq_desc[irq].affinity directly. Ingo, does this break anything?

* cpumask: centralize cpu_online_map and cpu_possible_mapRusty Russell2008-12-131-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [CRIS] Remove links from CRIS buildJesper Nilsson2008-10-313-138/+31
| | | | | | | | | | | | | | | | | | | | | Remove the links to architecture and machine dependent directories (boot, lib, drivers, arch, mach) The links were created and used mostly from the arch/cris/Makefile, so why not dispense with them altogether? Changed $(ARCH) to "cris" in Makefile, it is easier to read this way. The CRISv32 head.S common files for the kernel and compressed images needed to be modified to use ifdefs instead of using the now removed mach link. Since there are only two versions, this is not a huge loss in readability. The link to vmlinux.lds.S is also replaced with a merged version which uses ifdefs to select the correct layout. System.map before and after are identical. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com> Acked-by: Sam Ravnborg <sam@ravnborg.org>

* | kernel/cpu.c: create a CPU_STARTING cpu_chain notifierManfred Spraul2008-09-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now, there is no notifier that is called on a new cpu, before the new cpu begins processing interrupts/softirqs. Various kernel function would need that notification, e.g. kvm works around by calling smp_call_function_single(), rcu polls cpu_online_map. The patch adds a CPU_STARTING notification. It also adds a helper function that sends the message to all cpu_chain handlers. Tested on x86-64. All other archs are untested. Especially on sparc, I'm not sure if I got it right.

The old inflate code used a mark/release strategy rather than implement free. This new version instead keeps a count on the number of outstanding allocations and when it hits zero, it resets the malloc arena. This allows removing all the mark and release implementations and unifying all the malloc/free implementations. The architecture-dependent code must define two addresses: - free_mem_ptr, the address of the beginning of the area in which allocations should be made - free_mem_end_ptr, the address of the end of the area in which allocations should be made. If set to 0, then no check is made on the number of allocations, it just grows as much as needed The architecture-dependent code can also provide an arch_decomp_wdog() function call. This function will be called several times during the decompression process, and allow to notify the watchdog that the system is still running. If an architecture provides such a call, then it must define ARCH_HAS_DECOMP_WDOG so that the generic inflate code calls arch_decomp_wdog(). Work initially done by Matt Mackall, updated to a recent version of the kernel and improved by me.

* CRIS v32: Rewrite ARTPEC-3 gpio driver to avoid volatiles and general cleanup.Jesper Nilsson2008-02-081-174/+174
| | | | | | | | | | | | | | | | | | | | Changes as suggested by Andrew Morton, plus general cleanup to ease later consolidation of driver into machine common driver. - Correct parameter type of gpio_write to const char __user * - Remove volatile from the arrays of machine dependent registers, use readl and writel to access them instead. - Remove useless casts of void. - Use spin_lock_irqsave for locking. - Break gpio_write into smaller sub-functions. - Remove useless breaks after returns. - Don't perform any change in IO_CFG_WRITE_MODE if values are invalid. (previously values were set and then set to zero) - Change cast for copy_to_user to (void __user *) - Make file_operations gpio_fops static and const. - Make setget_output static. (However, it's still inline since the CRIS architecture is still not SMP, which makes the function small enough to inline)

* CRIS v32: Clean up nandflash.c for ARTPEC-3 and ETRAX FS.Jesper Nilsson2008-02-082-20/+24
| | | | | | | | | | Clean up issues noticed by Andrew Morton: - Use a combined struct for allocating the mtd_info and nand_chip structs instead of using anonymous memory as the example in Documentation/DocBook/mtdnand.tmpl - Use kzalloc instead of using kmalloc/memset(0) - Make crisv32_device_ready static.

* CRIS v32: Fix startup oops and replace hardcoded pagesize in vmlinux.lds.SJesper Nilsson2008-02-081-37/+37
| | | | | | | | | - Move alignment of init data to page size outside define CONFIG_BLK_DEV_INITRD This avoids oops due to memory on the same page as init data being freed. - Change hardcoded page size to use macro from asm/page.h - Add reserved memory via CONFIG_ETRAX_VMEM_SIZE. - Use available defines for TEXT_TEXT and INITCALLS. - Cleanup whitespace.
