x86: use new set_cpus_allowed_ptr function

2008-04-19T17:44:58+00:00

  * 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

x86: reduce memory and stack usage in intel_cacheinfo

2008-04-19T17:44:58+00:00

* Change the following static arrays sized by NR_CPUS to
  per_cpu data variables:

	_cpuid4_info *cpuid4_info[NR_CPUS];
	_index_kobject *index_kobject[NR_CPUS];
	kobject * cache_kobject[NR_CPUS];

* Remove the local NR_CPUS array with a kmalloc'd region in
  show_shared_cpu_map().

Also some minor complaints from checkpatch.pl fixed.

Kobject: convert arch/* from kobject_unregister() to kobject_put()

2008-01-25T04:40:39+00:00

There is no need for kobject_unregister() anymore, thanks to Kay's
kobject cleanup changes, so replace all instances of it with
kobject_put().

Kobject: change arch/x86/kernel/cpu/intel_cacheinfo.c to use kobject_init_and_add

2008-01-25T04:40:28+00:00

Stop using kobject_register, as this way we can control the sending of
the uevent properly, after everything is properly initialized.

x86: free_cache_attributes() section fix

2007-12-04T16:19:07+00:00

free_cache_attributes() must be __cpuinit since it calls the
__cpuinit cache_remove_shared_cpu_map().

This patch fixes the following section mismatch reported by
Chris Clayton:

 ...
 WARNING: vmlinux.o(.text+0x90b6): Section mismatch: reference to .init.text:cache_remove_shared_cpu_map (between 'free_cache_attributes' and 'show_level')

x86: convert cpuinfo_x86 array to a per_cpu array

2007-10-19T18:35:04+00:00

cpu_data is currently an array defined using NR_CPUS.  This means that
we overallocate since we will rarely really use maximum configured cpus.
When NR_CPU count is raised to 4096 the size of cpu_data becomes
3,145,728 bytes.

These changes were adopted from the sparc64 (and ia64) code.  An
additional field was added to cpuinfo_x86 to be a non-ambiguous cpu
index.  This corresponds to the index into a cpumask_t as well as the
per_cpu index.  It's used in various places like show_cpuinfo().

cpu_data is defined to be the boot_cpu_data structure for the NON-SMP
case.

x86: convert cpu_llc_id to be a per cpu variable

2007-10-19T18:35:03+00:00

Convert cpu_llc_id from a static array sized by NR_CPUS to a per_cpu
variable. This saves sizeof(cpu_llc_id) * NR unused cpus.  Access is
mostly from startup and CPU HOTPLUG functions.

Note there's an additional change of the type of cpu_llc_id from int to
u8 for ARCH i386 to correspond with the same type in ARCH x86_64.
