* sparc: Mark prom_early_alloc non-static.David S. Miller2008-12-063-2/+4

* sparc: Create common area for OF device layer code.David S. Miller2008-12-064-188/+122
| | | | | | | This is where common code implementations will go as we unify 32-bit and 64-bit OF device tree code. Signed-off-by: David S. Miller <davem@davemloft.net>
* sparc: Create common header file for prom_{32,64}.cDavid S. Miller2008-12-063-6/+12
| | | | | | | This is where common declarations will go as we unify these files as much as possible into common code. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | A closer inspection revealed that these two files had identical functionality - but the implementation of it differed slightly. Base it on the sparc version as it was the best. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of_node_put is needed before discarding a value received from of_find_node_by_name, eg in error handling code or when the device node is no longer used.

* sparc,sparc64: unify kernel/Sam Ravnborg2008-12-0490-0/+43306
| | | | | | | | | | | | | | | | 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.

* sparc: prepare kernel/ for unificationSam Ravnborg2008-12-0426-22/+54
| | | | | | | | | | | | | | | o sparc32 files with identical names to sparc64 renamed to <name>_32.S o introduced a few Kconfig helpers to simplify Makefile logic o refactored Makefile to prepare for unification - use obj-$(CONFIG_SPARC32) for sparc32 specific files - use <name>_$(BITS) for files where sparc64 has a _64 variant - sparc64 directly include a few files where sparc32 builds them, refer to these files directly (no BITS) - sneaked in -Werror as used by sparc64 o modified sparc/Makefile to use the new names for head/init_task Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

| | | | | | | | | | | | | This patch makes the two vmlinux.lds.S files identical and serve as documentation for the changes in each file. This mainly add stuffs to sparc32 that is otherwise only used by sparc64 and thus it should have no effect. Build tested only. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

* sparc32 cpuinit flase positivesAl Viro2008-11-305-8/+8
| | | | | | | | | | | 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). That one is left alone for now; just the trivial misannotation fixes. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* Revert "sparc: correct section of current_pc()"David S. Miller2008-11-101-1/+0
| | | | | | | | | 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 Weisbecker2008-10-231-0/+1
| | | | | | | | | | | | | | | 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 Weisbecker2008-10-231-1/+1
| | | | | | | | | | | | | | | | 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 Spraul2008-09-082-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
