      x86: use new set_cpus_allowed_ptr function · fc0e4748
      由 Mike Travis 提交于 
        * Use new set_cpus_allowed_ptr() function added by previous patch,
    which instead of passing the "newly allowed cpus" cpumask_t arg
    by value,  pass it by pointer:

    -int set_cpus_allowed(struct task_struct *p, cpumask_t new_mask)
    +int set_cpus_allowed_ptr(struct task_struct *p, const cpumask_t *new_mask)

  * Cleanup uses of CPU_MASK_ALL.

  * Collapse other NR_CPUS changes to arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.c
    Use pointers to cpumask_t arguments whenever possible.

Depends on:
	[sched-devel]: sched: add new set_cpus_allowed_ptr function

      [CPUFREQ] powernow-k8 print pstate instead of fid/did for family 10h · 4ae5c49f
      由 Yinghai Lu 提交于 
      powernow-k8: Found 1 Quad-Core AMD Opteron(tm) Processor 8354 processors (4 cpu cores) (version 2.20.00)

powernow-k8:    3 : fid 0x0 did 0x0 (1400 MHz)
powernow-k8:    4 : fid 0x0 did 0x0 (1100 MHz)

actually index for CPU_HW_PSTATE is pstate instead of fid/vid
So print it out as pstate.

      x86: Convert cpu_core_map to be a per cpu variable · 08357611
      由 Mike Travis 提交于 
      This is from an earlier message from 'Christoph Lameter':

    cpu_core_map is currently an array defined using NR_CPUS. This means that
    we overallocate since we will rarely really use maximum configured cpu.

    If we put the cpu_core_map into the per cpu area then it will be allocated
    for each processor as it comes online.

    This means that the core map cannot be accessed until the per cpu area
    has been allocated. Xen does a weird thing here looping over all processors
    and zeroing the masks that are not yet allocated and that will be zeroed
    when they are allocated. I commented the code out.

      [PATCH] more for_each_cpu() conversions · 394e3902
      由 Andrew Morton 提交于 
      When we stop allocating percpu memory for not-possible CPUs we must not touch
the percpu data for not-possible CPUs at all.  The correct way of doing this
is to test cpu_possible() or to use for_each_cpu().

This patch is a kernel-wide sweep of all instances of NR_CPUS.  I found very
few instances of this bug, if any.  But the patch converts lots of open-coded
test to use the preferred helper macros.
