* proc: add /proc/*/stackKen Chen2009-01-05
| | | | | | | | | | | | | | | | | | | | | /proc/*/stack adds the ability to query a task's stack trace. It is more useful than /proc/*/wchan as it provides full stack trace instead of single depth. Example output: $ cat /proc/self/stack [<c010a271>] save_stack_trace_tsk+0x17/0x35 [<c01827b4>] proc_pid_stack+0x4a/0x76 [<c018312d>] proc_single_show+0x4a/0x5e [<c016bdec>] seq_read+0xf3/0x29f [<c015a004>] vfs_read+0x6d/0x91 [<c015a0c1>] sys_read+0x3b/0x60 [<c0102eda>] syscall_call+0x7/0xb [<ffffffff>] 0xffffffff [add save_stack_trace_tsk() on mips, ACK Ralf --adobriyan] Signed-off-by: Ken Chen <kenchen@google.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

| * x86: setup_per_cpu_areas() cleanupCyrill Gorcunov2009-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | Impact: cleanup __alloc_bootmem and __alloc_bootmem_node do panic for us in case of fail so no need for additional checks here. Also lets use pr_*() macros for printing. Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| * cpumask: use alloc_cpumask_var_node where appropriateMike Travis2009-01-03
| | | | | | | | | | | | | | | | | | | | | | Impact: Reduce inter-node memory traffic. Reduces inter-node memory traffic (offloading the global system bus) by allocating referenced struct cpumasks on the same node as the referring struct.

| * cpumask: convert shared_cpu_map in acpi_processor* structs to cpumask_var_tRusty Russell2009-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: Reduce memory usage, use new API. This is part of an effort to reduce structure sizes for machines configured with large NR_CPUS. cpumask_t gets replaced by cpumask_var_t, which is either struct cpumask[1] (small NR_CPUS) or struct cpumask * (large NR_CPUS).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: Reduce future system panics due to cpumask operations using NR_CPUS Insure that code does not look at bits >= nr_cpu_ids as when cpumasks are allocated based on nr_cpu_ids, these extra bits will not be defined. Also some other minor updates: * change in to use cpu accessor function set_cpu_present() instead of directly accessing cpu_present_map w/cpu_clear() [arch/x86/kernel/reboot.c] * use cpumask_of() instead of &cpumask_of_cpu() [arch/x86/kernel/reboot.c] * optimize some cpu_mask_to_apicid_and functions.
