xen: make -fstack-protector work under Xen -fstack-protector uses a special per-cpu "stack canary" value. gcc generates special code in each function to test the canary to make sure that the function's stack hasn't been overrun. On x86-64, this is simply an offset of %gs, which is the usual per-cpu base segment register, so setting it up simply requires loading %gs's base as normal. On i386, the stack protector segment is %gs (rather than the usual kernel percpu %fs segment register). This requires setting up the full kernel GDT and then loading %gs accordingly. We also need to make sure %gs is initialized when bringing up secondary cpus too. To keep things consistent, we do the full GDT/segment register setup on both architectures. Because we need to avoid -fstack-protected code before setting up the GDT and because there's no way to disable it on a per-function basis, several files need to have stack-protector inhibited.

x86, trace: Add page fault tracepoints This patch introduces page fault tracepoints to x86 architecture by switching IDT. Two events, for user and kernel spaces, are introduced at the beginning of page fault handler for tracing. - User space event There is a request of page fault event for user space as below. https://lkml.kernel.org/r/1368079520-11015-2-git-send-email-fdeslaur+()+gmail+!+com https://lkml.kernel.org/r/1368079520-11015-1-git-send-email-fdeslaur+()+gmail+!+com - Kernel space event: When we measure an overhead in kernel space for investigating performance issues, we can check if it comes from the page fault events.

x86, pat: Migrate to rbtree only backend for pat memtype management Move pat backend to fully rbtree based implementation from the existing rbtree and linked list hybrid. New rbtree based solution uses interval trees (augmented rbtrees) in order to store the PAT ranges. The new code seprates out the pat backend to pat_rbtree.c file, making is cleaner. The change also makes the PAT lookup, reserve and free operations more optimal, as we don't have to traverse linear linked list of few tens of entries in normal case.

x86: replace CONFIG_X86_SMP with CONFIG_SMP The x86/Voyager subarch used to have this distinction between 'x86 SMP support' and 'Voyager SMP support': config X86_SMP bool depends on SMP && ((X86_32 && !X86_VOYAGER) || X86_64) This is a pointless distinction - Voyager can (and already does) use smp_ops to implement various SMP quirks it has - and it can be extended more to cover all the specialities of Voyager.

kmemcheck: add the kmemcheck core General description: kmemcheck is a patch to the linux kernel that detects use of uninitialized memory. It does this by trapping every read and write to memory that was allocated dynamically (e.g. using kmalloc()). If a memory address is read that has not previously been written to, a message is printed to the kernel log. Thanks to Andi Kleen for the set_memory_4k() solution. Andrew Morton suggested documenting the shadow member of struct page.

obj-$(CONFIG_AMD_NUMA) += amdtopology.o
x86-32, NUMA: Replace srat_32.c with srat.c SRAT support implementation in srat_32.c and srat.c are generally similar; however, there are some differences. First of all, 64bit implementation supports more types of SRAT entries. 64bit supports x2apic, affinity, memory and SLIT. 32bit only supports processor and memory. Most other differences stem from different initialization protocols employed by 64bit and 32bit NUMA init paths. On 64bit, * Mappings among PXM, node and apicid are directly done in each SRAT entry callback. * Memory affinity information is passed to numa_add_memblk() which takes care of all interfacing with NUMA init. * Doesn't directly initialize NUMA configurations. All the information is recorded in numa_nodes_parsed and memblks. On 32bit, * Checks numa_off. * Things go through one more level of indirection via private tables but eventually end up initializing the same mappings. * node_start/end_pfn[] are initialized and memblock_x86_register_active_regions() is called for each memory chunk. * node_set_online() is called for each online node. * sort_node_map() is called. There are also other minor differences in sanity checking and messages but taking 64bit version should be good enough. This patch drops the 32bit specific implementation and makes the 64bit implementation common for both 32 and 64bit. The init protocol differences are dealt with in two places - the numa_add_memblk() shim added in the previous patch and new temporary numa_32.c:get_memcfg_from_srat() which wraps invocation of x86_acpi_numa_init(). The shim numa_add_memblk() handles the folowings. * node_start/end_pfn[] initialization. * node_set_online() for memory nodes. * Invocation of memblock_x86_register_active_regions(). The shim get_memcfg_from_srat() handles the followings. * numa_off check. * node_set_online() for CPU nodes. * sort_node_map() invocation. * Clearing of numa_nodes_parsed and active_ranges on failure. The shims are temporary and will be removed as the generic NUMA init path in 32bit is replaced with 64bit one.
