Greg Kroah-Hartman 38a382ae5d Kobject: convert arch/* from kobject_unregister() to kobject_put()
There is no need for kobject_unregister() anymore, thanks to Kay's
kobject cleanup changes, so replace all instances of it with
kobject_put().

Greg Kroah-Hartman 5b3f355d8f Kobject: change arch/x86/kernel/cpu/intel_cacheinfo.c to use kobject_init_and_add
Stop using kobject_register, as this way we can control the sending of
the uevent properly, after everything is properly initialized.

Adrian Bunk f22d9bc1e8 x86: free_cache_attributes() section fix
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')

Mike Travis 92cb7612ae x86: convert cpuinfo_x86 array to a per_cpu array
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.

Mike Travis b6278470b7 x86: convert cpu_llc_id to be a per cpu variable
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.

Akinobu Mita ef1d7151d2 cpu hotplug: intel_cacheinfo: fix cpu hotplug error handling
- Fix resource leakage in error case within detect_cache_attributes()

- Don't register hotcpu notifier when cache_add_dev() returns error

- Introduce cache_dev_map cpumask to track whether cache interface for
  CPU is successfully added by cache_add_dev() or not.

  cache_add_dev() may fail with out of memory error. In order to
  avoid cache_remove_dev() with that uninitialized cache interface when
  CPU_DEAD event is delivered we need to have the cache_dev_map cpumask.

  (We cannot change cache_add_dev() from CPU_ONLINE event handler
  to CPU_UP_PREPARE event handler. Because cache_add_dev() needs
  to do cpuid and store the results with its CPU online.)

Satyam Sharma c789c037e9 x86: call cache_add_dev() from cache_sysfs_init() explicitly
Call cache_add_dev() from cache_sysfs_init() explicitly, instead of
referencing the CPU notifier callback directly from generic startup
code. Looks cleaner (to me at least) this way, and also makes it
possible to use other tricks to replace __cpuinit{data} annotations, as
recently discussed on this list.

Satyam Sharma 7b38493501 x86: intel_cacheinfo misc section annotation fixes
cache_shared_cpu_map_setup() and cache_remove_shared_cpu_map()
are functions called from another function that is __cpuinit.  But the
!CONFIG_SMP empty-body stubs of these functions are unconditionally
marked __init, which is actively wrong, and will lead to oops.  But we
never saw this oops, because they always managed to get inlined in their
callsites, by virtue of being empty-body stubs!  They should still be
__cpuinit, of course.

assocs[], levels[] and types[] are only referenced from function that is
__cpuinit.  So these are candidates for being marked __cpuinitdata.
