these bugs are harder to find than they seem, a stackdump helps. make it dependent on CONFIG_DEBUG_SHIRQ so that people can turn it off if it annoys them. Signed-off-by:

Ingo Molnar authored
An older binutils bug caused us to not fix up alternatives. This problem involved mutex.c but we dont do lockdep section tricks there anymore, so this workaround is moot. Keep the printk nevertheless, just in case ... We can remove that later on. Signed-off-by:

Change static bios_cpu_apicid array to a per_cpu data variable. This includes using a static array used during initialization similar to the way x86_cpu_to_apicid[] is handled. There is one early use of bios_cpu_apicid in apic_is_clustered_box(). The other reference in cpu_present_to_apicid() is called after smp_set_apicids() has setup the percpu version of bios_cpu_apicid.

Change the following static arrays sized by NR_CPUS to per_cpu data variables: char cpu_to_node_map[NR_CPUS]; fixup: - Split cpu_to_node function into "early" and "late" versions so that x86_cpu_to_node_map_early_ptr is not EXPORT'ed and the cpu_to_node inline function is more streamlined. - This also involves setting up the percpu maps as early as possible. - Fix X86_32 NUMA build errors that previous version of this patch caused. V2->V3: - add early_cpu_to_node function to keep cpu_to_node efficient - move and rename smp_set_apicids() to setup_percpu_maps() - call setup_percpu_maps() as early as possible V1->V2: - Removed extraneous casts - Fix !NUMA builds with '#ifdef CONFIG_NUMA" Signed-off-by: -

Add a generic option to clear any cpuid bit. I added it because it was very easy to add with the new generic cpuid disable bitmap and perhaps it will be useful in the future. Signed-off-by:

Modern 32bit userland doesn't even boot when the TSC is disabled because ld.so tends to contain RDTSCs. So make notsc only effective for the kernel, similar to 64bit. Signed-off-by:

This convers nofxsr, mem=nopentium and nosep to use the new generic cpuid disable bitmap instead of using own variables. Signed-off-by:
-
Andi Kleen authored
There are already various options to disable specific cpuid bits on the command line. They all use their own variable. Add a generic mask to make this easier in the future. Signed-off-by:

paravirt_pagetable_setup_{start,done}() are not used (yet) under x86_64, and native_pagetable_setup_{start,done}() don't exist on x86_64. So they don't need to be set. Signed-off-by: -

Add .set_pgd field to pv_mmu_ops. Implement pud_val(), __pud(), set_pgd(), pud_clear(), pgd_clear(). pud_clear() and pgd_clear() are implemented simply using set_pud() and set_pmd(). They don't have a field at pv_mmu_ops. Signed-off-by:

__pmd, pmd_val and set_pud are used before they are defined (as static) We move them a little up in the file, so it doesn't happen. Signed-off-by:

This patch fills in the read and write cr8 fields with their native version. Signed-off-by:
-
Glauber de Oliveira Costa authored
Since the cr8 manipulation functions ended up staying in the tree, they can't be defined just when PARAVIRT is off: In this patch, those functions are defined for the PARAVIRT case too. [ mingo@elte.hu: fixes ] Signed-off-by:

We use a __stringify construction at paravirt_patch_64.c. It's better practice to include the stringify header directly Signed-off-by:

currently when gart iommu is enabled by BIOS or previous we got " Checking aperture... CPU 0: aperture @4000000 size 64MB CPU 1: aperture @4000000 size 64MB " we should use use Node instead. we will get " Checking aperture...

Move the select_idle_routine() call to after the detect_ht() call at identify_cpu() on 64-bit. This change is for printing the polling idle and HT enabled warning message properly. Signed-off-by:

Hiroshi Shimamoto authored
The warning message at idle_setup() is never shown because smp_num_sibling hasn't been updated at this point yet. Move this polling idle and HT enabled warning to select_idle_routine(). I also implement this warning on 64-bit kernel. Signed-off-by:
