2008-09-12sparc64: Kill sparse warnings in mm/init.hDavid S. Miller
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>
2008-09-12sparc64: Fix sparse warnings in fault.cDavid S. Miller
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>
2008-09-12sparc64: Remove explicit initialization of mmu_gathersDavid S. Miller
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>
2008-09-12sparc64: Fix sparse warnings in vio.cDavid S. Miller
Several variables should be marked static. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-12sparc64: Fix sparse warnings in pci_sun4v.cDavid S. Miller
'err' variable shadowing in pci_sun4v_probe() Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-11sparc64: Fix sparse warnings in pci.cDavid S. Miller
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>
2008-09-11sparc64: Fix sparse warnings in of_device.cDavid S. Miller
Passing unsigned int pointer where plain int pointer is expected. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-11sparc64: Fix sparse warnings in prom.cDavid S. Miller
1) Testing null with '0' 2) returning void-valued expression Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-11sparc64: Fix sparse warnings in visemul.cDavid S. Miller
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>
2008-09-11sparc64: Fix sparse warnings in kernel/time.cDavid S. Miller
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>
2008-09-11sparc64: Define WANT_PAGE_VIRTUALDavid S. Miller
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>
2008-09-11sysctl: Use header file for sysctl knob declarations on sparc.David S. Miller
This also takes care of a sparse warning as scons_pwroff's definition point. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-11sysctl: Use CONFIG_SPARC instead of __sparc__ for ifdef tests.David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-11sparc64: Fix sparse warnings in global reg snapshotting.David S. Miller
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>
2008-09-11sparc64: Add __arch64__ to CHECKFLAGSDavid S. Miller
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>
2008-09-10sparc32: Call parse_early_param() in setup_arch().David S. Miller
Mirror sparc64. This will allow us to use early_param() on sparc32 too. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-10sparc64: Kill hand-crafted I/O accessors in PCI controller drivers.David S. Miller
Use existing upa_{read,write}q() interfaces instead. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-10sparc64: Commonize large portions of PSYCHO error handling.David S. Miller
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>
2008-09-10sparc64: Create and use psycho_pbm_init_common().David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-10sparc64: Start commonizing code common between SABRE and PSYCHO.David S. Miller
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>
2008-09-10sparc64: Record OF device instead of device node pointer in pci_pbm_info.David S. Miller
Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-10sparc64: Get rid of pci_controller_info.David S. Miller
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>
2008-09-10sparc32: Need to close openned RTC device just like sparc64.David S. Miller
Otherwise we get refcount problems. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-07rtc-m48t59: fix setting of a year on m48t08 and m48t02 rtcsKrzysztof Helt
Fix setting of a year in m48t08 and m48t02 clocks. They do not have century bits and setting them causes the year to overflow (bit 0x80 set). Problem found by Robert Reif on Sun Sparcstation 20. Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-03sparc32: add init memory poisoningRobert Reif
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>

2008-09-03sparc32: use RTC subsystemDavid S. Miller
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. [ Add proper RTC layer calls to set_rtc_mmss() -DaveM ] Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-03rtc-m48t59: allow externally mapped ioaddrKrzysztof Helt
Add support for externally mapped ioaddr. This is required on sparc32 as the ioaddr must be mapped with of_ioremap(). Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-03rtc-m48t59: add support for M48T02 and M48T59 chipsKrzysztof Helt
Add support for two compatible RTC: - M48T08 which does not have alarm part, - M48T08 which does not have alarm part and has only 2KB of NVRAM These types covers all Mostek's RTC used in Sun UltraSparc workstations. Tested on Sun Ultra60 with M48T59 RTC.

2008-09-03sparc64: Prevent sparc64 from invoking irq handlers on offline CPUsPaul E. McKenney
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>
2008-09-03sparc64: Fix IPI call locking.David S. Miller
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>
2008-09-03sparc: Fix handling of LANCE and ESP parent nodes in of_device.cDavid S. Miller
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. Based upon a bug report from Robert Reif. Signed-off-by: David S. Miller <davem@davemloft.net>
