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>
2008-09-11sparc64: 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>
2008-09-10sparc64: Fix return value in update_persistent_clock().David S. Miller
Noticed by Stephen Rothwell. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-09sparc: remove unused includesBjoern B. Brandenburg
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>
2008-09-08sparc64: Add missing rtc_close() in update_persistent_clock()David S. Miller
Noticed by David Brownell. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-08sparc32: Move sun4d show_leds() out of asm/obio.hDavid S. Miller
Put it, as well as cpu_leds[] array, into sun4d_irq.c Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-07sparc64: fix wrong m48t59 RTC yearKrzysztof Helt
Correctly calculate offset to the year register for Mostek RTC. 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>
2008-09-03sparc: Remove asm/rtc.hDavid S. Miller

No longer needed. 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>
2008-09-03sparc64: 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>
2008-09-02sparc32: Fix sun4c build warnings.David S. Miller

2008-09-02sparc64: Move reboot handling into seperate file and kill power reg programming.David S. Miller
We should always use prom_power_off(). Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-01sparc64: Apply const or __initdata to vio_device_id[]David S. Miller
This mirrors the of_device_id[] changes done in fd098316ef533e8441576f020ead4beab93154ce ("sparc: Annotate of_device_id arrays with const or __initdata.") Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-31sparc64: Clean up CPU chip type probing code.David S. Miller
Three main things: 1) Make prober an arch initcall instead of using hard-coded invocation from paging_init() 2) Shrink table size, the fpu ident stuff was never used. 3) Use named struct initialized in table. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-31sparc: remove CONFIG_SUN4Adrian Bunk
While doing some easy cleanups on the sparc code I noticed that the CONFIG_SUN4 code seems to be worse than the rest - there were some "I don't know how it should work, but the current code definitely cannot work." places. And while I have seen people running Linux on machines like a SPARCstation 5 a few years ago I don't recall having seen sun4 machines, even less ones running Linux.

2008-08-31sparc64: Rewrite central driver.David S. Miller
This driver is now limited to just doing the basic clock board and FHC chip initialization and registering the platform devices for the per-board LEDs, which are driven by the new LEDS_STARFIRE driver. The IRQ register handling is already confined purely to the device tree code. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-31sparc64: Delete starfire_cpu_setup().David S. Miller
It does nothing. Signed-off-by: David S. Miller <davem@davemloft.net>

As suggested by Stephen Rothwell. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-30sparc: Stop setting NO_DMA.David S. Miller
This fixes the build with PCI disabled, we do want the generic DMA facilities and interfaces even when just SBUS is enabled. Based upon a build failure report by Robert Reif. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-30sparc64: Convert FIRE PCI controller driver into a real driver.David S. Miller
