* sparc: Convert remaining sbus_ioremap() and sbus_iounmap() users.David S. Miller2008-08-291-1/+4
| | | | | | Use of_ioremap() and of_iounmap() instead. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Remove dinky old-style SBUS probing facilities.David S. Miller2008-08-292-26/+0
| | | | | | | No drivers or code uses this stuff any more, every driver has been converted over to OF device probing. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Remove SBUS layer resource and irq handling.David S. Miller2008-08-292-31/+0
| | | | | | | All the drivers use OF device objects now for this information. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Kill SBUS layer IRQ hooks.David S. Miller2008-08-292-20/+0
| | | | | | IRQs are obtained by drivers from the of_device struct. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Make mmu_map_dma_area and mmu_unmap_dma_area take a device pointer.David S. Miller2008-08-291-4/+4
| | | | | | | This lets us kill this "map it in every IOMMU" crazy code, and also some of the final references to sbus_root. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Kill mmu_translate_dvma and implementations.David S. Miller2008-08-291-2/+0
| | | | | | No longer used. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Convert SBUS floppy probing to use OF device objects.David S. Miller2008-08-291-18/+27
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Move SBUS DMA attribute interfaces out of asm/sbus.hDavid S. Miller2008-08-294-8/+22
| | | | | | | | | This is in preparation for the subsequent asm/sbus.h removal. Also, make these routines take a "struct device" or no arguments, as appropriate. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Convert all SBUS drivers to dma_*() interfaces.David S. Miller2008-08-292-80/+0
| | | | | | | | | And all the SBUS dma interfaces are deleted. A private implementation remains inside of the 32-bit sparc port which exists only for the sake of the implementation of dma_*(). Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Implement more generic dma_*() interfaces.David S. Miller2008-08-291-5/+54
| | | | | | | | | These dispatch to either PCI or SBUS routines based upon the device bus type. This will allow us to let SBUS drivers call these routines. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Make mmu_{get,release}_*() take a struct device pointer.David S. Miller2008-08-291-9/+13
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Make SBUS DMA interfaces take struct device.David S. Miller2008-08-292-45/+23
| | | | | | | This is the first step in converting all the SBUS drivers over to generic dma_*(). Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Make IOMMU and IO-UNIT init work with device nodes.David S. Miller2008-08-292-0/+4
| | | | | | | | | | | And stick the iommu archdata pointer into the generic OF device tree of_device struct as well. We still have to pass the sbus_bus object down into the routines so that the SBUS bus objects get the iommu cookies set properly. After drivers get converted to being pure OF drivers, that can go away. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Kill SBUS DVMA layer.David S. Miller2008-08-294-498/+147
| | | | | | | | | | | | | This thing was completely pointless. Just find the OF device in the parent of drivers that want to program this device, and map the DMA regs inside such drivers too. This also moves the dummy claim_dma_lock() and release_dma_lock() implementation to floppy_32.h, which makes it handle this issue just like floppy_64.h does. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Kill videopix SBUS driver.David S. Miller2008-08-292-59/+0
| | | | | | | This has been marked BROKEN for a long time and it's more likely to get rewritten from scratch than to be fixed up and made usable. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Delete bare sbus char bpp driver, obsoleted by parport_sunbppDavid S. Miller2008-08-292-74/+0
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix irq_of_parse_and_map() and irq_dispose_mapping().David S. Miller2008-08-261-2/+4
| | | | | | | | | | | | | | | Stephen Rothwell noticed that I committed an earlier version of the patch that didn't have two things fixed: 1) irq_of_parse_and_map() should return "unsigned int" not "int" and it should return zero for "no irq" 2) irq_dispose_mapping() should be an inline function, not a macro, for type checking With feedback and suggestions from Anton Vorontsov. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Add generic interface for registering a dimm printing handler.David S. Miller2008-08-251-0/+9
| | | | | | | | | | | | | The way to do this varies by platform type and the exact memory controller the cpu uses. For Spitfire cpus we currently just use prom_getunumber() and hope that works. For Cheetah cpus we have a memory controller driver that can compute this information. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Add GPIO layer support.David S. Miller2008-08-251-0/+36
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Implement irq_of_parse_and_map() and irq_dispose_mapping().David S. Miller2008-08-251-0/+8
| | | | | | | This allows more OF layer code to be shared between powerpc and sparc. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Add mutex for set property calls.David S. Miller2008-08-251-0/+2
| | | | | | | | | | | | | On some platforms, the I2C controller is shared between the OS and OBP. OBP uses this I2C controller to access the EEPROM, and thus is programmed when the kernel calls prom_setprop(). Wrap such calls with the new of_set_property_mutex. Relevant I2C bus drivers can grab this mutex around top-level I2C operations to provide the proper protection. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Implement IRQ stacks.David S. Miller2008-08-131-0/+4

* sparc: remove include of linux/of_device.h from asm/of_device.hStephen Rothwell2008-08-131-2/+1
| | | | | | | | Now that all the direct includes of asm/of_device.h are gone, this is safe to do. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: don't use asm/of_device.hStephen Rothwell2008-08-085-5/+7
| | | | | | | Use linux/of_device.h instead. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* of/sparc: remove include of linux/of_platform.h from asm/of_platform.hStephen Rothwell2008-08-071-3/+0
| | | | | | | | Now that we have removed all inclusions of asm/of_platform.h, this compatability include can be removed. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Add __KERNEL__ ifdef protection to pt_regs helpers.David S. Miller2008-08-012-26/+25
| | | | | | | | | Some of them use 'bool' and whatnot and therefore are not kosher for userspace, so don't export them there. Reported by Roland McGrath. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Hook up trigger_all_cpu_backtrace().David S. Miller2008-07-311-0/+3
| | | | | | | We already have code that does this, but it is only currently attached to sysrq-'y'. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Make global reg dumping even more useful.David S. Miller2008-07-311-4/+4
| | | | | | | | | | Record one more level of stack frame program counter. Particularly when lockdep and all sorts of spinlock debugging is enabled, figuring out the caller of spin_lock() is difficult when the cpu is stuck on the lock. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: FUTEX_OP_ANDN fixMikael Pettersson2008-07-311-1/+1
| | | | | | | | | | | | | | | | Correct sparc64's implementation of FUTEX_OP_ANDN to do a bitwise negate of the oparg parameter before applying the AND operation. All other archs that support FUTEX_OP_ANDN either negate oparg explicitly (frv, ia64, mips, sh, x86), or do so indirectly by using an and-not instruction (powerpc). Since sparc64 has and-not, I chose to use that solution. I've not found any use of FUTEX_OP_ANDN in glibc so the impact of this bug is probably minor. But other user-space components may try to use it so it should still get fixed. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: David S. Miller <davem@davemloft.net>

* sparc64: Kill isa_bus_type.David S. Miller2008-07-301-1/+0
| | | | | | | I forgot to delete this when I removed the ISA bus layer from the sparc ports. Signed-off-by: David S. Miller <davem@davemloft.net>

* sparc64: tracehook: TIF_NOTIFY_RESUMERoland McGrath2008-07-281-3/+5
| | | | | | | This adds TIF_NOTIFY_RESUME support for sparc64. When set, we call tracehook_notify_resume() on the way to user mode. Signed-off-by: Roland McGrath <roland@redhat.com>

* sparc: enable headers_export againSam Ravnborg2008-07-271-1/+45
| | | | | | | Update include/asm/Kbuild so we export all relvant headers for sparc. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
* sparc, sparc64: use arch/sparc/includeSam Ravnborg2008-07-27327-0/+32037
The majority of this patch was created by the following script: *** ASM=arch/sparc/include/asm mkdir -p $ASM git mv include/asm-sparc64/ftrace.h $ASM git rm include/asm-sparc64/* git mv include/asm-sparc/* $ASM sed -ie 's/asm-sparc64/asm/g' $ASM/* sed -ie 's/asm-sparc/asm/g' $ASM/* *** The rest was an update of the top-level Makefile to use sparc for header files when sparc64 is being build. And a small fixlet to pick up the correct unistd.h from sparc64 code. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
