2008-10-07sparc32: sun4m interrupt mask cleanupRobert Reif
Here is an updated version of a patch I wrote 6 years ago http://marc.info/?l=linux-sparc&m=103939103607617&w=2 that simplifies interrupt mask lookup. It's main purpose is to add VME bus support but it's really a cleanup of the mask code. Signed-off-by: Robert Reif <reif@earthlink.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-09-21sparc: arch/sparc/kernel/pmc.c -- extra #include?David Brownell
I have no SPARC compiler handy to verify, but it looks like this is another file that doesn't need <linux/miscdevices.h> ... Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-19sparc32: Stop calling claim_ticker14() from sun4c_irq.cDavid S. Miller
Since the first argument is always NULL, the only side effect is to disable the PROFILE_IRQ, so just do that directly. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-19sparc32: Call sun4m_clear_profile_irq() directly from sun4m_smp.cDavid S. Miller
This is the only use of the clear_profile_irq() btfixup entry, which just eats up lots of dead space on other platform types. A subsequent commit will delete the other implementations and the btfixup entry as well. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-09-12sparc: Fix user_regset 'n' field values.David S. Miller
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>

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>
2008-09-11sparc64: 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: 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>
2008-09-10sparc32: 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>
2008-09-10sparc32: Fix function signature of of_bus_sbus_get_flags().David S. Miller
This doesn't match the function pointer type it gets assigned to. Luckily, this was harmless. 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>

2008-09-08kernel/cpu.c: create a CPU_STARTING cpu_chain notifierManfred Spraul
Right now, there is no notifier that is called on a new cpu, before the new cpu begins processing interrupts/softirqs. Various kernel function would need that notification, e.g. kvm works around by calling smp_call_function_single(), rcu polls cpu_online_map. The patch adds a CPU_STARTING notification. It also adds a helper function that sends the message to all cpu_chain handlers. Tested on x86-64. All other archs are untested. Especially on sparc, I'm not sure if I got it right.

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.

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>

2008-08-31sparc64: 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>
