2007-12-07[IA64] Fix iosapic interrupt delivery mode for CPEKenji Kaneshige
If "CPEI Processor Override" bit is not set in "Platform Interrupt Source Flags" in "Platform Interrupt Sources Structure" in ACPI MADT, the target processor of CPEI is restricted to a specific CPU. Because of this, the delivery mode for CPEI should be IOSAPIC_FIXED. Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Tony Luck <tony.luck@intel.com>

Currently, XPC's heartbeat timer function runs on whatever CPU modprobe/insmod ran on when XPC was started.

2007-11-06[IA64] Disable/re-enable CPE interrupts on AltixRuss Anderson

2007-11-06[IA64] Fix section mismatch in contig.c version of per_cpu_init()Tony Luck
There is a section mismatch when building CONFIG_FLATMEM=y kernels that also have CONFIG_HOTPLUG_CPU=y WARNING: vmlinux.o(.text+0x5a902): Section mismatch: reference to \ .init.text:__alloc_bootmem (between 'per_cpu_init' and 'count_pages') The issue occurs because per_cpu_init() in mm/contig.c is marked __cpuinit (which is #define'd to nothing on a hot plug cpu configuration) call __alloc_bootmem() (which is an __init function). The usage is actually safe because the __alloc_bootmem() is inside an "if (first_time)" test so that the call is only made while it is still legal to do so. But the warning is irritating.

2007-10-29[IA64] /proc/cpuinfo "physical id" field cleanupsAlex Chiang
Clean up the process for presenting the "physical id" field in /proc/cpuinfo. - remove global smp_num_cpucores, as it is mostly useless - remove check_for_logical_procs(), since we do the same functionality in identify_siblings() - reflow logic in identify_siblings(). If an older CPU does not implement PAL_LOGICAL_TO_PHYSICAL, we may still be able to get useful information from SAL_PHYSICAL_ID_INFO - in identify_siblings(), threads/cores are a property of the CPU, not the platform - remove useless printk's about multi-core / thread capability in identify_siblings(), as that information is readily available in /proc/cpuinfo, and printing for the BSP only adds little value - smp_num_siblings is now meaningful if any CPU in the system supports threads, not just the BSP - expose "physical id" field, even on CPUs that are not multi-core / multi-threaded (as long as we have a valid value).

2007-10-22kexec: add BSS to resource treeBernhard Walle
Add the BSS to the resource tree just as kernel text and kernel data are in the resource tree. The main reason behind this is to avoid crashkernel reservation in that area. While it's not strictly necessary to have the BSS in the resource tree (the actual collision detection is done in the reserve_bootmem() function before), the usage of the BSS resource should be presented to the user in /proc/iomem just as Kernel data and Kernel code. Note: The patch currently is only implemented for x86 and ia64 (because efi_initialize_iomem_resources() has the same signature on i386 and ia64).

2007-10-19Use extended crashkernel command line on ia64Bernhard Walle
This patch adapts IA64 to use the generic parse_crashkernel() function instead of its own parsing for the crashkernel command line. Because the total amount of System RAM must be known when calling this function, efi_memmap_init() is modified to return its accumulated total_memory variable. Also, the crashkernel handling is moved in an own function in arch/ia64/kernel/setup.c to make the code more readable.

2007-10-19pid namespaces: changes to show virtual ids to userPavel Emelyanov
This is the largest patch in the set. Make all (I hope) the places where the pid is shown to or get from user operate on the virtual pids. The idea is: - all in-kernel data structures must store either struct pid itself or the pid's global nr, obtained with pid_nr() call; - when seeking the task from kernel code with the stored id one should use find_task_by_pid() call that works with global pids; - when showing pid's numerical value to the user the virtual one should be used, but however when one shows task's pid outside this task's namespace the global one is to be used; - when getting the pid from userspace one need to consider this as the virtual one and use appropriate task/pid-searching functions.

2007-10-19pid namespaces: define is_global_init() and is_container_init()Serge E. Hallyn
is_init() is an ambiguous name for the pid==1 check. Split it into is_global_init() and is_container_init(). A cgroup init has it's tsk->pid == 1. A global init also has it's tsk->pid == 1 and it's active pid namespace is the init_pid_ns. But rather than check the active pid namespace, compare the task structure with 'init_pid_ns.child_reaper', which is initialized during boot to the /sbin/init process and never changes. Changelog: 2.6.22-rc4-mm2-pidns1: - Use 'init_pid_ns.child_reaper' to determine if a given task is the global init (/sbin/init) process. This would improve performance and remove dependence on the task_pid(). 2.6.21-mm2-pidns2: - [Sukadev Bhattiprolu] Changed is_container_init() calls in {powerpc, ppc,avr32}/traps.c for the _exception() call to is_global_init(). This way, we kill only the cgroup if the cgroup's init has a bug rather than force a kernel panic.

2007-10-17add-vmcore: add a prefix "VMCOREINFO_" to the vmcoreinfo macrosKen'ichi Ohmichi

So these names should be changed.
