This patch get rid of smp_boot_cpus(), since it does not boot any cpu anymore. Its code is split in a way to make it closer to x86_64 Signed-off-by:

if smp configuration is not found at all, hook into 0. This is done to match x86_64 Signed-off-by:

They look similar enough, and are merged. Only difference (zap_low_mapping for i386) is inside ifdef Signed-off-by:
-
Glauber de Oliveira Costa authored
it is practically the same between arches now, so it is moved to smpboot.c. Minor differences (gdt initialization) live inside an ifdef Signed-off-by:

This is a very large patch, because it depends on a lot of auxiliary static functions. But they all have been modified to the point that they're sufficiently close now. So they're just merged in smpboot.c Signed-off-by:

This is to match i386. The former name was cuter, but the current is more meaningful and more general, since cpu_id can be a logical id. Signed-off-by:
-

voyager would conflict with it, but the types are ultimately compatible. So remove the extern definition from voyager_smp.c in favour of the common one Signed-off-by:

Move map_cpu_to_logical_apicid() and unmap_cpu_to_logical_apicid() to smpboot.c. They take together all the bunch of static functions they rely upon Signed-off-by:

Now that we boot cpus here, callin_map has this meaning (same as x86_64) Signed-off-by:

wakeup_secondary_via_INIT => wakeup_secondary_cpu. This is to match i386, where init is not always used. Signed-off-by:
-

After the inclusion, a lot of files needs fixing for conflicts, some of them in the headers themselves, to accomodate for both i386 and x86_64 versions. [ mingo@elte.hu: build fix ] Signed-off-by:

We don't need __smp_prepare_cpu anymore. Signed-off-by:

This patch provides minor adjustments for do_boot_cpus in both architectures to allow for integration Signed-off-by:
-

We do it to make it close to x86_64. The later needs it, otherwise the nmi watchdog can get into the scene and kill us with a hammer. Enabling irqs here used to trigger a bug in i386. This is because time irq handling relies upon structures that are only initialized after smp initcalls (More precisely, it will find per_cpu(hrtimer_bases, cpu)->cb_pending list not initialized and crash) Signed-off-by:
-

It splits setup_local_APIC in two, providing a function corresponding to the ending part of it. As a side effect, smp_callin looks the same between i386 and x86_64. Signed-off-by:
-
Glauber de Oliveira Costa authored
it is a little bit more complicated than x86_64 due to erratas and other stuff, but its existance will ease integration Signed-off-by:

Glauber de Oliveira Costa authored
We introduce empty macros just to make them look like the same Signed-off-by:
-
Glauber de Oliveira Costa authored
We can do it now that do_boot_cpu has its own worker. Signed-off-by:
-
Glauber de Oliveira Costa authored
Use a new worker, with help of the create_idle struct to fork the idle thread. We now have two workers, the first of them triggered by __smp_prepare_cpu. But the later is going away soon. Signed-off-by:

As we now boot cpus from cpu_up, we don't need it. Signed-off-by:
-
Glauber de Oliveira Costa authored
After all the infrastructure work, we're now prepared to boot the cpus from cpu_up, and not from prepare_cpus. So the difference between cold boot and hotplug is effectively over, and the functions are used to the purposes they're meant to. Signed-off-by:
-

It was okay when cpus were cold booted before this point. But with the new state machine, they will not have arrived to the trampoline yet. zapping low mappings will have the bad effect of breaking it completely after paging enablement Signed-off-by:

Only call schedule_work if keventd is already running. This is already the way x86_64 does Signed-off-by:
-
Glauber de Oliveira Costa authored
it is redundant, since it is already done by set_cpu_sibling_map() Signed-off-by:
-
Glauber de Oliveira Costa authored
this does not exist, so it will be an empty macro Signed-off-by:

With this, remove its late_initcall marker from nmi_32.c Signed-off-by:
-
Glauber de Oliveira Costa authored
Two more files goes away. nmi_64.h and nmi_32.h gives birth to nmi.h Signed-off-by:

use mach_traps when it is supposed to be used. Signed-off-by:

Glauber de Oliveira Costa authored
By this time, they are already set in init routines Signed-off-by:
-
Glauber de Oliveira Costa authored
We move it to apic_32.c, since it's irq related anyway, and only called from that file. Signed-off-by:
-

We do it and also fix conflicts, which makes x86_64 automatically closer to i386 Signed-off-by:

this patch allows x86_64 to use subarch mach_ headers in practice, since x86_64 does not have any subarch, it will use mach_default. But it will allow for substantially less code duplication Signed-off-by:
-

the cpu count is changed accordingly: now, what matters is online cpus. Also, we add those functions for x86_64 Signed-off-by:

It will ease integration for x86_64 Signed-off-by:

Impressing friends is a very important thing. Do it in a separate function to make it even more explicit, and ease integration. Signed-off-by:
