| | | | | | | | | | | | | | | | | | | | If we cannot determine the CPU or FPU report "Unknown CPU" or "Unknown FPU" like sparc64 does. And report with KERN_ERR that we cannot determine the CPU. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | Sparc64 uses a non-recursive sibling traversal algorithm that never got propagated into the sparc32 copy of this code. Sync them up. Signed-off-by: David S. Miller <davem@davemloft.net>

* | sparc: Commonize get_one_property() implementations.David S. Miller2008-12-05
| | | | | | | | | | | | | | | | Add final len assignment in sparc64's get_one_property() (it's necessary to avoid unchecked return value warnings on the sparc32 side), and mark name argument const on sparc32's copy. Signed-off-by: David S. Miller <davem@davemloft.net>
* | sparc: Move property building code into prom_common.cDavid S. Miller2008-12-05
| | | | | | | | | | | | | | | | | | | | Unfortunately there is some sparc32/sparc64 ifdef'ery in here due to the difference in how the prom_firstprop() and prom_nextprop() routines work. This will be eliminated eventually. Signed-off-by: David S. Miller <davem@davemloft.net>

* | sparc,sparc64: unify kernel/Sam Ravnborg2008-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Move all files from sparc64/kernel/ to sparc/kernel - rename as appropriate o Update sparc/Makefile to the changes o Update sparc/kernel/Makefile to include the sparc64 files NOTE: This commit changes link order on sparc64! Link order had to change for either of sparc32 and sparc64. And assuming sparc64 see more testing than sparc32 change link order on sparc64 where issues will be caught faster.

| | | | | | | | | | | All noise since we don't have CPU hotplug there. However, they did expose something very odd-looking in there - poke_viking() does a bunch of identical btfixup each time it's called (i.e. for each CPU).

| | | | | | | | | This reverts commit 8dd9453737822469837d48d5da3785ce70fb2118. This fixes a boot failure reported by Robert Reif. The code above the section change expects to fallthrough, so we can't make such a section change here.

* sparc: correct section of current_pc()Frederic Weisbecker2008-10-23
| | | | | | | | | | | | | | | Latest mainline gives this section mismatch on sparc: The function current_pc() references the variable __init no_sun4u_here. This is often because current_pc lacks a __init annotation or the annotation of no_sun4u_here is wrong. Since current_pc() is used only in early time, it is correct to put it in .init section.

* sparc: correct section of apc_no_idleFrederic Weisbecker2008-10-23
| | | | | | | | | | | | | | | | The latest mainline gives this section mismatch on sparc: The function __devinit apc_probe() references a variable __initdata apc_no_idle. If apc_no_idle is only used by apc_probe then annotate apc_no_idle with a matching annotation. Since the commit 7e7e2f035663c5ceb029bfb9d91e75099b0a5625, apc_probe() is on __devinit so we have to correct apc_no_idle which is referenced by this function.

| | * kernel/cpu.c: create a CPU_STARTING cpu_chain notifierManfred Spraul2008-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
