2010-10-18irq_work: Add generic hardirq context callbacksPeter Zijlstra2-7/+1
Provide a mechanism that allows running code in IRQ context. It is most useful for NMI code that needs to interact with the rest of the system -- like wakeup a task to drain buffers. Perf currently has such a mechanism, so extract that and provide it as a generic feature, independent of perf so that others may also benefit. The IRQ context callback is generated through self-IPIs where possible, or on architectures like powerpc the decrementer (the built-in timer facility) is set to generate an interrupt immediately. Architectures that don't have anything like this get to do with a callback from the timer tick. These architectures can call irq_work_run() at the tail of any IRQ handlers that might enqueue such work (like the perf IRQ handler) to avoid undue latencies in processing the work.

2010-10-15llseek: automatically add .llseek fopArnd Bergmann1-0/+1
All file_operations should get a .llseek operation so we can make nonseekable_open the default for future file operations without a .llseek pointer. The three cases that we can automatically detect are no_llseek, seq_lseek and default_llseek. For cases where we can we can automatically prove that the file offset is always ignored, we use noop_llseek, which maintains the current behavior of not returning an error from a seek. New drivers should normally not use noop_llseek but instead use no_llseek and call nonseekable_open at open time. Existing drivers can be converted to do the same when the maintainer knows for certain that no user code relies on calling seek on the device file. The generated code is often incorrectly indented and right now contains comments that clarify for each added line why a specific variant was chosen. In the version that gets submitted upstream, the comments will be gone and I will manually fix the indentation, because there does not seem to be a way to do that using coccinelle. Some amount of new code is currently sitting in linux-next that should get the same modifications, which I will do at the end of the merge window. Many thanks to Julia Lawall for helping me learn to write a semantic patch that does all this. ===== begin semantic patch ===== // This adds an llseek= method to all file operations, // as a preparation for making no_llseek the default. // // The rules are // - use no_llseek explicitly if we do nonseekable_open // - use seq_lseek for sequential files // - use default_llseek if we know we access f_pos // - use noop_llseek if we know we don't access f_pos, // but we still want to allow users to call lseek // @ open1 exists @ identifier nested_open; @@ nested_open(...) { <+... nonseekable_open(...) ...+> } @ open exists@ identifier open_f; identifier i, f; identifier open1.nested_open; @@ int open_f(struct inode *i, struct file *f) { <+...

This sets up a generic SRAM pool for CPUs and platform code to insert their otherwise unused memories into. A simple alloc/free interface is provided (lifed from avr32) for generic code.

2010-10-14sh: pci: Support secondary FPGA-driven PCIe clocks on SDK7786.Paul Mundt4-5/+75
The SDK7786 FPGA has secondary control over the PCIe clocks, specifically relating to the slots and oscillator. This ties the FPGA clocks in to the clock framework and balances the refcounting similar to how the primary on-chip clocks are managed. While the on-chip clocks are per-port, the FPGA clock enable/disable is global for the entire block. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

SDK7786 supports connecting either slot3 or 4 to the same PCIe port by way of FPGA muxing. By default the vertical slot 3 on the baseboard is enabled, so this adds in a command line option for forcibly enabling the slot 4 edge connector. If nothing has been specified on the command line, we fall back to reading the resistor values for card presence to figure out where to route the port to.

2010-10-12memblock, bootmem: Round pfn properly for memory and reserved regionsYinghai Lu1-2/+2
We need to round memory regions correctly -- specifically, we need to round reserved region in the more expansive direction (lower limit down, upper limit up) whereas usable memory regions need to be rounded in the more restrictive direction (lower limit up, upper limit down). This introduces two set of inlines: memblock_region_memory_base_pfn() memblock_region_memory_end_pfn() memblock_region_reserved_base_pfn() memblock_region_reserved_end_pfn() Although they are antisymmetric (and therefore are technically duplicates) the use of the different inlines explicitly documents the programmer's intention. The lack of proper rounding caused a bug on ARM, which was then found to also affect other architectures.

Now that we've got a generic perf-events based oprofile backend we might as well make use of it seeing as SH doesn't do anything special with its oprofile backend. Also introduce a new CONFIG_HW_PERF_EVENTS symbol so that we can fallback to using the timer interrupt for oprofile if the CPU doesn't support perf events. Also, to avoid a section mismatch warning we need to annotate oprofile_arch_exit() with an __exit marker.

2010-10-07Fix IRQ flag handling namingDavid Howells2-8/+8
Fix the IRQ flag handling naming. In linux/irqflags.h under one configuration, it maps: local_irq_enable() -> raw_local_irq_enable() local_irq_disable() -> raw_local_irq_disable() local_irq_save() -> raw_local_irq_save() ... and under the other configuration, it maps: raw_local_irq_enable() -> local_irq_enable() raw_local_irq_disable() -> local_irq_disable() raw_local_irq_save() -> local_irq_save() ... This is quite confusing. There should be one set of names expected of the arch, and this should be wrapped to give another set of names that are expected by users of this facility. Change this to have the arch provide: flags = arch_local_save_flags() flags = arch_local_irq_save() arch_local_irq_restore(flags) arch_local_irq_disable() arch_local_irq_enable() arch_irqs_disabled_flags(flags) arch_irqs_disabled() arch_safe_halt() Then linux/irqflags.h wraps these to provide: raw_local_save_flags(flags) raw_local_irq_save(flags) raw_local_irq_restore(flags) raw_local_irq_disable() raw_local_irq_enable() raw_irqs_disabled_flags(flags) raw_irqs_disabled() raw_safe_halt() with type checking on the flags 'arguments', and then wraps those to provide: local_save_flags(flags) local_irq_save(flags) local_irq_restore(flags) local_irq_disable() local_irq_enable() irqs_disabled_flags(flags) irqs_disabled() safe_halt() with tracing included if enabled. The arch functions can now all be inline functions rather than some of them having to be macros.

2010-10-07sh: Fix up the SH-3 build.Paul Mundt1-0/+1
SH-3 lacks an MMUCR_TI definition for global TLB flushes. As SH-3 parts lack a split TLB, the same global flush behaviour is accomplished through the flush bit, which just happens to be the same as on SH-4. This fixes up the build for all SH-3 MMU parts.

2010-10-05modules: Fix module_bug_list list corruption raceLinus Torvalds1-2/+0
With all the recent module loading cleanups, we've minimized the code that sits under module_mutex, fixing various deadlocks and making it possible to do most of the module loading in parallel. However, that whole conversion totally missed the rather obscure code that adds a new module to the list for BUG() handling. That code was doubly obscure because (a) the code itself lives in lib/bugs.c (for dubious reasons) and (b) it gets called from the architecture-specific "module_finalize()" rather than from generic code. Calling it from arch-specific code makes no sense what-so-ever to begin with, and is now actively wrong since that code isn't protected by the module loading lock any more. So this commit moves the "module_bug_{finalize,cleanup}()" calls away from the arch-specific code, and into the generic code - and in the process protects it with the module_mutex so that the list operations are now safe. Future fixups: - move the module list handling code into kernel/module.c where it belongs. - get rid of 'module_bug_list' and just use the regular list of modules (called 'modules' - imagine that) that we already create and maintain for other reasons.

2010-10-05sh: Wire up INTC subgroup splitting for SH7786 SCIF1.Paul Mundt1-38/+72
SH7786 is the big user for subgroup splitting, mostly for the PCIe block, but those will follow later. For now we simply split up SCIF1, as used by the serial console on SDK7786 and others. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-05sh: intc: Support virtual mappings for IRQ subgroups.Paul Mundt1-0/+2
Many interrupts that share a single mask source but are on different hardware vectors will have an associated register tied to an INTEVT that denotes the precise cause for the interrupt exception being triggered. This introduces the concept of IRQ subgroups in the intc core, where a virtual IRQ map is constructed for each of the pre-defined cause bits, and a higher level chained handler takes control of the parent INTEVT. This enables CPUs with heavily muxed IRQ vectors (especially across disjoint blocks) to break things out in to a series of managed chained handlers while being able to dynamically lookup and adopt the IRQs created for them. This is largely an opt-in interface, requiring CPUs to manually submit IRQs for subgroup splitting, in addition to providing identifiers in their enum maps that can be used for lazy lookup via the radix tree.

2010-10-04sh: mach-x3proto: Improve ILSEL debugging.Paul Mundt1-4/+12
At the moment ILSEL blows up with a BUG when aliased sets are handed in, but as the enable call is able to hand back errors we opt for that path instead. None of the ILSEL peripherals are vital to the board's operation, so trapping a BUG is a bit excessive. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-10-02sh: Support early IRQ vector map reservation for delayed controllers.Paul Mundt2-9/+17
Some controllers will need to be initialized lazily due to pinmux constraints, while others may simply have no need to be brought online if there are no backing devices for them attached. In this case it's still necessary to be able to reserve their hardware vector map before dynamic IRQs get a hold of them. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
