* x86: merge smp_32.h and smp_64.h into smp.hGlauber Costa2008-04-17
| | | | | | | | Merge what's left from smp_32.h and smp_64.h into smp.h By now, they're basically extern definitions. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: merge SMP definitions of smp.hGlauber Costa2008-04-17
| | | | | | | | | we merge everything that is inside CONFIG_SMP to smp.h. They differ a little bit, so we use CONFIG_X86_32_SMP and CONFIG_X86_64_SMP as markers. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: merge includes in smp.hGlauber Costa2008-04-17
| | | | | | | move all include directives from smp_{32,64}.h to smp.h. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: merge hard/logical_smp_processor_idGlauber Costa2008-04-17
| | | | | | | | | | The code is now the same between i386 and x86_64. We already know what happens when it reaches this point: They go away from the arch-specific headers, and suddenly appears in the common header.

* x86: change boot_cpu_id to boot_cpu_physical_apicidGlauber de Oliveira Costa2008-04-17

* Revert "i386: export i386 smp_call_function_mask() to modules"Thomas Gleixner2007-10-27
| | | | | | | | | | | | | | | | This reverts commit 6442eea937ef797d4b66733f49c82e2fdc2aca6f. The patch breaks smp_ops and needs to be reverted. The solution to allow modular build of KVM is to export smp_ops instead.

| * x86: convert cpu_to_apicid to be a per cpu variableMike Travis2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts the x86_cpu_to_apicid array to be a per cpu variable. This saves sizeof(apicid) * NR unused cpus. Access is mostly from startup and CPU HOTPLUG functions. MP_processor_info() is one of the functions that require access to the x86_cpu_to_apicid array before the per_cpu data area is setup. For this case, a pointer to the __initdata array is initialized in setup_arch() and removed in smp_prepare_cpus() after the per_cpu data area is initialized. A second change is included to change the initial array value of ARCH i386 from 0xff to BAD_APICID to be consistent with ARCH x86_64.

* x86: Convert cpu_core_map to be a per cpu variableMike Travis2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | This is from an earlier message from 'Christoph Lameter': cpu_core_map is currently an array defined using NR_CPUS. This means that we overallocate since we will rarely really use maximum configured cpu. If we put the cpu_core_map into the per cpu area then it will be allocated for each processor as it comes online. This means that the core map cannot be accessed until the per cpu area has been allocated. Xen does a weird thing here looping over all processors and zeroing the masks that are not yet allocated and that will be zeroed when they are allocated. I commented the code out.
