* [SPARC64]: Fix register usage in xor_raid_4().David S. Miller2007-10-131-6/+6
| | | | | | | | | Some typos led to using %i6/%i7 instead of %l6/%l7 in loads which is really really bad because those are the frame pointer and return PC. Based upon a raid5 crash report by Bertrand Joel. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Kill pci_memspace_mask.David S. Miller2007-10-136-52/+30
| | | | | | | It is totally unnecessary as the needed information is properly encoded in the resources. Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Consolidate MSI support code.David S. Miller2007-10-136-775/+700
| | | | | | | | | | | | | | | | This also makes us use the MSI queues correctly. Each MSI queue is serviced by a normal sun4u/sun4v INO interrupt handler. This handler runs the MSI queue and dispatches the virtual interrupts indicated by arriving MSIs in that MSI queue. All of the common logic is placed in pci_msi.c, with callbacks to handle the PCI controller specific aspects of the operations. This common infrastructure will make it much easier to add MSG support.

* [SPARC/64]: Move of_platform_driver initialisations: arch/sparc{,64}.Stephen Rothwell2007-10-134-4/+12
| | | | | | | | We no longer initialise the name field of the of_platform_driver, but use the name field of the embedded device_driver's name field instead. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC64]: Fix bugs in SYSV IPC handling in 64-bit processes.David S. Miller2007-10-131-11/+4
| | | | | | | | | | | | | | | | | Thanks to Tom Callaway for the excellent bug report and test case. sys_ipc() has several problems, most to due with semaphore call handling: 1) 'err' return should be a 'long' 2) "union semun" is passed in a register on 64-bit compared to 32-bit which provides it on the stack and therefore by reference 3) Second and third arguments to SEMCTL are swapped compared to 32-bit.

* [SPARC/64]: Prepare to remove of_platform_driver name.Stephen Rothwell2007-10-132-2/+8
| | | | | | | | | | | | | The name field of of_platform_driver is just copied into the included device_driver. By not overriding an already initialised device_driver name, we can convert the drivers over time to stop using the of_platform_driver name. Also we were not copying the owner field from of_platform_driver, so do the same with it. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
* [SPARC32]: Add irqflags.h to sparc32 and use it from generic code.Robert Reif2007-10-132-6/+10
| | | | | | | | | | | | | | | | | | | Added asm-sparc/irqflags.h and moved irq related code from system.h to it. Renamed local_irq functions to raw_local_irq in irq.c. Modified system.h to include linux/irqflags.h which includes asm/irqflags.h. Added TRACE_IRQFLAGS_SUPPORT to Kconfig.debug. This is the first step in adding IRQ-flags state tracing as outlined in Documentation/irqflags-tracing.txt. These changes should be harmless because they just move things around and rename them. The next step is making the lowlevel entry code modifications which to be honest are beyond my capabilities at this point. Boot tested on an ss20 running an SMP kernel.

* [SPARC64]: beautify vmlinux.ldsSam Ravnborg2007-10-131-89/+122
| | | | | | | | | | | | | Apply a consistent format to vmlinux.lds. The file is now to some degree readable. In addition move several labels inside the braces such that they reflect the actual start address of a section. Without this the label would not reflect if ld added alignment.

* [SPARC]: beautify vmlinux.ldsSam Ravnborg2007-10-131-72/+93
| | | | | | | | | | | Make vmlinux.lds almost readable. When going through the file fixed the following: - Use PAGE_SIZE as replacement for hardcoded 4096 - Moves label definitions inside {} to avoid ld alignment that may be added between label and section Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

* [SPARC64]: Enable MSI on sun4u Fire PCI-E controllers.David S. Miller2007-10-132-1/+516
| | | | | | | | The support code is identical to the hypervisor sun4v stuff, just replacing the hypervisor calls with register reads and writes in the Fire controller. Signed-off-by: David S. Miller <davem@davemloft.net>
* i2c/tps65010: New-style driver updates, part 2David Brownell2007-10-133-5/+143
| | | | | | | | | | | | | Switch the tps65010 driver into a "new-style" I2C driver, and convert all of its in-tree users (board support for OSK, H2, H3) accordingly. That accounts for most of the board-specific code in this driver; the rest of that code is now moved into board-specific initcalls. Also remove some of the many now-superfluous #includes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the x86 merge, lots of files that referenced their own filenames are no longer correct. Rather than keep them up to date, just delete them, as they add no real value. Additionally: - fix up comment formatting in scx200_32.c - Remove a credit from myself in setup_64.c from a time when we had no SCM - remove longwinded history from tsc_32.c which can be figured out from git.

* | minimal build fixes for uml (fallout from x86 merge)Al Viro2007-10-136-11/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a) include/asm-um/arch can't just point to include/asm-$(SUBARCH) now b) arch/{i386,x86_64}/crypto are merged now c) subarch-obj needed changes d) cpufeature_64.h should pull "cpufeature_32.h", not <asm/cpufeature_32.h> since it can be included from asm-um/cpufeature.h e) in case of uml-i386 we need CONFIG_X86_32 for make and gcc, but not for Kconfig f) sysctl.c shouldn't do vdso_enabled for uml-i386 (actually, that one should be registered from corresponding arch/*/kernel/*, with ifdef going away; that's a separate patch, though). With that and with Stephen's patch ("[PATCH net-2.6] uml: hard_header fix") we have uml allmodconfig building both on i386 and amd64.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The consistent DMA stuff was evolved from the old PCI DMA mapping functions. As this has been overhauled, it's something that is used by the generic DMA mapping code, and thus, has no intrinsic PCI dependence.
