2011-12-22sparc64: Fix MSIQ HV call ordering in pci_sun4v_msiq_build_irq().David S. Miller
This silently was working for many years and stopped working on Niagara-T3 machines. We need to set the MSIQ to VALID before we can set it's state to IDLE. On Niagara-T3, setting the state to IDLE first was causing HV_EINVAL errors. The hypervisor documentation says, rather ambiguously, that the MSIQ must be "initialized" before one can set the state. I previously understood this to mean merely that a successful setconf() operation has been performed on the MSIQ, which we have done at this point. But it seems to also mean that it has been set VALID too. Signed-off-by: David S. Miller <davem@davemloft.net>
2011-10-31sparc: add export.h to arch/sparc files as requiredPaul Gortmaker
These files are only exporting symbols, so they don't need the full module.h header file. Previously they were getting access to EXPORT_SYMBOL implicitly via overuse of module.h from within other .h files, but that is being cleaned up. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2011-03-30sparc64: Fix section mis-match errors.David S. Miller
Fix all of the problems spotted by CONFIG_DEBUG_SECTION_MISMATCH under arch/sparc during a 64-bit defconfig build. They fall into two categorites: 1) of_device_id is marked as __initdata, and we can never do this since these objects sit in the device core data structures way past boot. So even if a driver will never be reloaded, we have to keep the device ID table around. Mark such cases const instead. 2) The bootmem alloc/free handling code in mdesc.c was not fully marked __init as it should be, thus generating a reference to free_bootmem_late() (which is __init) from non-__init code.

2011-03-16sparc64: Fix build errors with gcc-4.6.0David S. Miller
Most of the warnings emitted (we fail arch/sparc file builds with -Werror) were legitimate but harmless, however one case (n2_pcr_write) was a genuine bug. Based almost entirely upon a patch by Sam Ravnborg. Reported-by: Dennis Gilmore <dennis@ausil.us> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-16sparc64: rename virt_irq => irq - IISam Ravnborg
The generic irq support uses the term 'irq' for the allocated irq number. Fix it so sparc64 use the same term for an irq as the generic irq support does. For a naive reader this is less confusing. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-02-28dt/sparc: Eliminate users of of_platform_{,un}register_driverGrant Likely
Get rid of old users of of_platform_driver in arch/sparc. Most of_platform_driver users can be converted to use the platform_bus directly. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2010-07-24sparc: remove references to of_device and to_of_deviceGrant Likely
of_device is just a #define alias to platform_device. This patch replaces all references to it with platform_device. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S. Miller <davem@davemloft.net>
2010-07-24of/platform: remove all of_bus_type and of_platform_bus_type referencesGrant Likely
Both of_bus_type and of_platform_bus_type are just #define aliases for the platform bus. This patch removes all references to them and switches to the of_register_platform_driver()/of_unregister_platform_driver() API for registering. Subsequent patches will convert each user of of_register_platform_driver() into plain platform_drivers without the of_platform_driver shim. At which point the of_register_platform_driver()/of_unregister_platform_driver() functions can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S. Miller <davem@davemloft.net>
2010-05-22of: Remove duplicate fields from of_platform_driverGrant Likely
.name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.

2010-05-18of: Always use 'struct device.of_node' to get device node pointer.Grant Likely
The following structure elements duplicate the information in 'struct device.of_node' and so are being eliminated. This patch makes all readers of these elements use device.of_node instead. (struct of_device *)->node (struct dev_archdata *)->prom_node (sparc) (struct dev_archdata *)->of_node (powerpc & microblaze) Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2009-08-10sparc: Remove no-op dma_4v_sync_single_for_cpu and dma_4v_sync_sg_for_cpuFUJITA Tomonori
Now sparc uses include/asm-generic/dma-mapping-common.h. pci_sun4v.c doesn't need to have no-op dma_4v_sync_single_for_cpu and dma_4v_sync_sg_for_cpu (dma-mapping-common.h does nothing if sync_{single|sg}_for_cpu hook is not defined). So we can remove them safely. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Tested-by: Robert Reif <reif@earthlink.net> Acked-by: David S.

2009-06-16sparc: use dma_map_page instead of dma_map_singleFUJITA Tomonori
This patch converts dma_map_single and dma_unmap_single to use map_page and unmap_page respectively and removes unnecessary map_single and unmap_single. map_page can be used to implement map_single but the opposite is impossible. Having only dma_map_page in struct dma_ops is enough. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Tested-by: Robert Reif <reif@earthlink.net> Signed-off-by: David S.

2009-01-06sparc64: Use unsigned long long for u64.Sam Ravnborg
Andrew Morton wrote: People keep on doing printk("%llu", some_u64); testing it only on x86_64 and this generates a warning storm on powerpc, sparc64, etc. Because they use `long', not `long long'. Quite a few 64-bit architectures are using `long' for their s64/u64 types. We should convert them all to `long long'. 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. This patch introduces additional warnings in several drivers. These will be dealt with in separate patches.

2008-12-04sparc,sparc64: unify kernel/Sam Ravnborg
o Move all files from sparc64/kernel/ to sparc/kernel - rename as appropriate o Update sparc/Makefile to the changes o Update sparc/kernel/Makefile to include the sparc64 files NOTE: This commit changes link order on sparc64! Link order had to change for either of sparc32 and sparc64. And assuming sparc64 see more testing than sparc32 change link order on sparc64 where issues will be caught faster.
