2008-04-17x86: get boot_cpu_id as early for k8_scan_nodesYinghai Lu
When acpi=off or there is no SRAT defined, apicid_to_node is got from K8 Northbridge PCI configuration space in k8_scan_nodes() in arch/x86_64/mm/k8toplogy.c. The problem is that it assumes bsp apic id is 0 at that point. For four socket system with Quad core cpus installed, all cpus apic id is offset by 4, and bsp apic id is 4. For eight socket system with dual core cpus installed, all cpus apic id is offset by 2, and bsp apic id is 2. We need get boot_cpu_id --- bsp apic id, before k8_scan_nodes by called. So create early_acpi_boot_init and early_get_smp_config for get boot_cpu_id. Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-04-17x86: correct/clarify comment in nops.hMikael Pettersson
<asm-x86/nops.h> describes certain multibyte instructions as "generic" nops when in fact they aren't nops at all in 64-bit mode (missing REX.W causing truncation of a register). Update the comment to state that K8 or P6 style nops should be used in 64-bit mode. This matches what the alternatives code does.

2008-04-17x86: prevent unconditional writes to DebugCtl MSRJan Beulich
Otherwise, enabling (or better, subsequent disabling) of single stepping would cause a kernel oops on CPUs not having this MSR. The patch could have been added a conditional to the MSR write in user_disable_single_step(), but centralizing the updates seems safer and (looking forward) better manageable.

2008-04-17x86: enhance DEBUG_RODATA support - alternativesMathieu Desnoyers
Fix a memcpy that should be a text_poke (in apply_alternatives). Use kernel_wp_save/kernel_wp_restore in text_poke to support DEBUG_RODATA correctly and so the CPU HOTPLUG special case can be removed. Add text_poke_early, for alternatives and paravirt boot-time and module load time patching. Changelog: - Fix text_set and text_poke alignment check (mixed up bitwise and and or) - Remove text_set - Export add_nops, so it can be used by others. - Document text_poke_early. - Remove clflush, since it breaks some VIA architectures and is not strictly necessary. - Add kerneldoc to text_poke and text_poke_early. - Create a second vmap instead of using the WP bit to support Xen and VMI. - Move local_irq disable within text_poke and text_poke_early to be able to be sleepable in these functions.

2008-04-17x86: unify setup_trampolineGlauber Costa
setup_trampoline() looks very similar between architectures, and this patch unifies them. The i386 version allocates bootmem memory, while the x86_64 version uses a fixed address. In this patch, we initialize the global trampoline_base to the x86_64 version, and i386 allocation can later override it.
