* [PATCH] declare smp_call_function_single in generic codeRandy Dunlap2006-12-071-0/+7
| | | | | | | | | | | | smp_call_function_single() needs to be visible in non-SMP builds, to fix: arch/x86_64/kernel/vsyscall.c:283: warning: implicit declaration of function 'smp_call_function_single' Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] smp_call_function_single() cleanupAndrew Morton2006-09-261-0/+3
| | | | | | | | | | | | If we're going to implement smp_call_function_single() on three architecture with the same prototype then it should have a declaration in a non-arch-specific header file. Move it into <linux/smp.h>. Cc: Stephane Eranian <eranian@hpl.hp.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] add smp_setup_processor_id()Andrew Morton2006-06-301-0/+2
| | | | | | | | | | | | | Presently, smp_processor_id() isn't necessarily set up until setup_arch(). But it's used in boot_cpu_init() and printk() and perhaps in other places, prior to setup_arch() being called. So provide a new smp_setup_processor_id() which is called before anything else, wire it up for Voyager (which boots on a CPU other than #0, and broke).

* [PATCH] on_each_cpu(): disable local interruptsAndrew Morton2006-03-221-14/+9
| | | | | | | | | | | | | | | | | | | When on_each_cpu() runs the callback on other CPUs, it runs with local interrupts disabled. So we should run the function with local interrupts disabled on this CPU, too. And do the same for UP, so the callback is run in the same environment on both UP and SMP. (strictly it should do preempt_disable() too, but I think local_irq_disable is sufficiently equivalent). Also uninlines on_each_cpu(). softirq.c was the most appropriate file I could find, but it doesn't seem to justify creating a new file. Oh, and fix up that comment over (under?) x86's smp_call_function(). It drives me nuts. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] remove bogus asm/bug.h includes.Al Viro2006-02-071-1/+0
| | | | | | | A bunch of asm/bug.h includes are both not needed (since it will get pulled anyway) and bogus (since they are done too early). Removed. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | This reverts commit af2b4079ab154bd12e8c12b02db5f31b31babe63 Changing the #define to an inline function breaks on non-SMP builds, since wuite a few places in the kernel do not implement the ipi handler when compiling for UP. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [NET]: Shut up warnings in net/core/flow.cRussell King2005-11-221-1/+7
| | | | | | | | | | | | | | Not really a network problem, more a !SMP issue. net/core/flow.c:295: warning: statement with no effect flow.c:295: smp_call_function(flow_cache_flush_per_cpu, &info, 1, 0); Fix this by converting the macro to an inline function, which also increases the typechecking for !SMP builds.

* Revert broken "statement with no effect" warning fixLinus Torvalds2005-07-281-16/+4
| | | | | | | | | | It may shut up gcc, but it also incorrectly changes the semantics of the smp_call_function() helpers. You can fix the warning other ways if you are interested (create another inline function that takes no arguments and returns zero), but preferably gcc just shouldn't complain about unused return values from statement expressions in the first place.
* [PATCH] alpha: fix "statement with no effect" warningsRichard Henderson2005-07-281-4/+16
| | | | | | | | | | | | | Apparently gcc 4.0 complains about "({ 0; });", which leads to -Werror breakage in one of the alpha oprofile modules. One might could argue that this is a gcc bug, in that statement-expressions should be considered to be function-like rather than statement-like for the purposes of this warning. But it's just as easy to use an inline function in the first place, side-stepping the issue. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] smp_processor_id() cleanupIngo Molnar2005-06-211-24/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements a number of smp_processor_id() cleanup ideas that Arjan van de Ven and I came up with. The previous __smp_processor_id/_smp_processor_id/smp_processor_id API spaghetti was hard to follow both on the implementational and on the usage side. Some of the complexity arose from picking wrong names, some of the complexity comes from the fact that not all architectures defined __smp_processor_id. In the new code, there are two externally visible symbols: - smp_processor_id(): debug variant. - raw_smp_processor_id(): nondebug variant. Replaces all existing uses of _smp_processor_id() and __smp_processor_id(). Defined by every SMP architecture in include/asm-*/smp.h. There is one new internal symbol, dependent on DEBUG_PREEMPT: - debug_smp_processor_id(): internal debug variant, mapped to smp_processor_id(). Also, i moved debug_smp_processor_id() from lib/kernel_lock.c into a new lib/smp_processor_id.c file. All related comments got updated and/or clarified. I have build/boot tested the following 8 .config combinations on x86: {SMP,UP} x {PREEMPT,!PREEMPT} x {DEBUG_PREEMPT,!DEBUG_PREEMPT} I have also build/boot tested x64 on UP/PREEMPT/DEBUG_PREEMPT. (Other architectures are untested, but should work just fine.)

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+139
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
