* sparc32: Use PROM device probing for sun4m timer registers.David S. Miller2008-09-14
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Fix user_regset 'n' field values.David S. Miller2008-09-12
| | | | | | | | | | As noticed by Russell King, we were not setting this properly to the number of entries, but rather the total size. This results in the core dumping code allocating waayyyy too much memory. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix sparse warnings in chmc.cDavid S. Miller2008-09-12
| | | | | | Several constants are larger than 32-bit and need "UL" markers. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Kill sparse warnings in mm/init.hDavid S. Miller2008-09-12
| | | | | | | | | | | 1) Several exported symbols need extern decls, they are exported not for C code but for assembler routines. 2) PAGE_EXEC isn't used, delete 3) Several larger than 32-bit constants need "UL" markers Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix sparse warnings in fault.cDavid S. Miller2008-09-12
| | | | | | | | | 1) set_brkpt() is referenced by nothing and hasn't been used by anyone to my knowledge for many many years. So just delete it. 2) add extern decl for do_sparc64_fault() in asm/pgtable_64.h Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Remove explicit initialization of mmu_gathersDavid S. Miller2008-09-12
| | | | | | | | | | | This was just needed to work around an ancient gcc bug that we don't care about any more. It was also causing a sparse warnings: arch/sparc64/mm/tlb.c:22:52: warning: Using plain integer as NULL pointer Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix sparse warnings in vio.cDavid S. Miller2008-09-12
| | | | | | Several variables should be marked static. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix sparse warnings in pci_sun4v.cDavid S. Miller2008-09-12
| | | | | | 'err' variable shadowing in pci_sun4v_probe() Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix sparse warnings in pci.cDavid S. Miller2008-09-12
| | | | | | | | | | 1) Declare pci_poke_* in pci_impl.h 2) of_create_pci_dev() should be static 3) ->setup_msi_irq() wants an unsigned int pointer not a plain int one 4) void value expression return in arch_teardown_msi_irq() Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix sparse warnings in of_device.cDavid S. Miller2008-09-12
| | | | | | | Passing unsigned int pointer where plain int pointer is expected. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix sparse warnings in prom.cDavid S. Miller2008-09-12
| | | | | | | 1) Testing null with '0' 2) returning void-valued expression Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix sparse warnings in visemul.cDavid S. Miller2008-09-12
| | | | | | | 1) edge8 tables should be static 2) add vis_emul() extern decl. to asm/visasm.h Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix sparse warnings in kernel/time.cDavid S. Miller2008-09-12
| | | | | | | | | 1) Using "clock" as a local variable shadows a global variable of the same name declared in linux/clocksource.h 2) rtc_cmos_resource should be static Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Define WANT_PAGE_VIRTUALDavid S. Miller2008-09-12
| | | | | | | | | | | | As sparse warns, without this struct page pointer subtraction is extremely expensive, and this is a pretty common operation in fast paths. With this define struct page becomes 64 bytes which makes for a simple subtract and shift, instead of a costly divide or reciprocol multiply. Signed-off-by: David S. Miller <davem@davemloft.net>
* sysctl: Use header file for sysctl knob declarations on sparc.David S. Miller2008-09-12
| | | | | | | This also takes care of a sparse warning as scons_pwroff's definition point. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix sparse warnings in global reg snapshotting.David S. Miller2008-09-12
| | | | | | | Lots of shadowed local variables and global_reg_snapshot[] needs an extern declaration in asm/ptrace_64.h. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Add __arch64__ to CHECKFLAGSDavid S. Miller2008-09-12
| | | | | | | | | | | Otherwise sparse doesn't work. The 32 vs. 64 header ifdef used under arch/sparc/include/asm/ is: #if defined(__sparc__) && defined(__arch64__) And that doesn't work for sparse unless we give it __arch64__ Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Call parse_early_param() in setup_arch().David S. Miller2008-09-11
| | | | | | | Mirror sparc64. This will allow us to use early_param() on sparc32 too. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Kill hand-crafted I/O accessors in PCI controller drivers.David S. Miller2008-09-11
| | | | | | Use existing upa_{read,write}q() interfaces instead. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Commonize large portions of PSYCHO error handling.David S. Miller2008-09-11
| | | | | | | The IOMMU and streaming cache error interrogation is moved here as well as the PCI error interrupt handler. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Create and use psycho_pbm_init_common().David S. Miller2008-09-11
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Start commonizing code common between SABRE and PSYCHO.David S. Miller2008-09-11
| | | | | | | | | | These are very similar chips, in fact they are identical in some macro blocks. So start commonizing code which they can share. We begin with the IOMMU initialization sequence. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Record OF device instead of device node pointer in pci_pbm_info.David S. Miller2008-09-11
| | | | Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Get rid of pci_controller_info.David S. Miller2008-09-11
| | | | | | | | | | It is just used as a parent to encapsulate two PBM objects. But that layout is only really relevant and necessary for psycho PCI controllers, which unlike all the others share a single IOMMU instance between sibling PCI busses. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc32: Need to close openned RTC device just like sparc64.David S. Miller2008-09-10
| | | | | | Otherwise we get refcount problems. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc64: Fix return value in update_persistent_clock().David S. Miller2008-09-10
| | | | | | Noticed by Stephen Rothwell. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: remove unused includesBjoern B. Brandenburg2008-09-09
| | | | | | | | The spinlock code does not use NR_CPUS. Compile tested using allyesconfig and allnoconfig. Signed-off-by: Bjoern B. Brandenburg <bbb@cs.unc.edu> Signed-off-by: David S. Miller <davem@davemloft.net>

| * sparc64: Prevent sparc64 from invoking irq handlers on offline CPUsPaul E. McKenney2008-09-03
| | | | | | | | | | | | | | | | | | | | Make sparc64 refrain from clearing a given to-be-offlined CPU's bit in the cpu_online_mask until it has processed pending irqs. This change prevents other CPUs from being blindsided by an apparently offline CPU nevertheless changing globally visible state. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * sparc64: Fix IPI call locking.David S. Miller2008-09-03
| | | | | | | | | | | | | | | | | | | | When I switched sparc64 over to the generic helpers for smp_call_function(), I didn't convert the dinky call_lock we had. Use ipi_call_lock() and ipi_call_unlock(). Signed-off-by: David S. Miller <davem@davemloft.net>

| * sparc: Fix resource flags for PCI children in OF device tree.David S. Miller2008-08-29
| | | | | | | | | | | | | | | | | | | | | | | | When a device is under an EBUS or ISA bus, the resource flags don't get set properly. Fix this by re-evaluating the resource flags at each level of bus as we apply ranges on the way to the root. And let PCI override any existing flags setting, but don't let the default flags calculator make such overrides. Signed-off-by: David S. Miller <davem@davemloft.net>
| * sparc32: Implement smp_call_function_single().David S. Miller2008-08-27
| | | | | | | | | | | | | | | | Reported by Stephen Rothwell. Needed to fix the build when CONFIG_RELAY is enabled. Signed-off-by: David S. Miller <davem@davemloft.net>

* | sparc32: add init memory poisoningRobert Reif2008-09-03
| | | | | | | | | | | | | | | | | | This patch adds init memory poisoning. It looks like totalram_pages was not updated properly in free_initrd_mem so I fixed that as well. Signed-off-by: Robert Reif <reif@earthlink.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* | sparc32: use RTC subsystemDavid S. Miller2008-09-03
| | | | | | | | | | | | | | | | | | | | | | | | Use rtc subsystem for sparc32 architecture. Actually, only one driver is needed: m48t59 as it supports the most common clocks on sparc32 machines: m48t08 and m48t02.

* | sparc: Fix handling of LANCE and ESP parent nodes in of_device.cDavid S. Miller2008-09-03
| | | | | | | | | | | | | | | | | | | | The device nodes that sit above 'esp' and 'le' on SBUS lack a 'ranges' property, but we should pass the translation up to the parent node so that the SBUS level ranges get applied.
