Subject: [GIT PULL] AMD thresholding fixes for 3.6

Hi Ingo,

those didn't make it in time for the merge window so I'm sending them
now so at they can spend their quality time in linux-next.

Please pull, thanks.

The following changes since commit f8f5701bdaf9134b1f90e5044a82c66324d2073f:

  Linux 3.5-rc1 (2012-06-02 18:29:26 -0700)

AMD thresholding fixes for 3.6

Those are a bunch of patches which give the MCE thresholding code a
hard look and a scrubbing to remove a couple of annoyances like sysfs
warnings when running CPU off-/online tests and the threshold_bank4 node
under /sys/devices/system/machinecheck/ is a symlink.

It also gives proper names to the thresholding banks instead of simply
enumerating them, like this:

     /sys/devices/system/machinecheck/machinecheck0/
     |-- bank0
     |-- bank1
     |-- bank2
     |-- bank3
     |-- bank4
     |-- bank5
     |-- bank6
     |-- check_interval
     |-- cmci_disabled
     |-- combined_unit
     |   |-- combined_unit
     |       |-- error_count
     |       |-- threshold_limit
     |-- dont_log_ce
     |-- execution_unit
     |   |-- execution_unit
     |       |-- error_count
     |       |-- threshold_limit
     |-- ignore_ce
     |-- insn_fetch
     |   |-- insn_fetch
     |       |-- error_count
     |       |-- threshold_limit
     |-- load_store
     |   |-- load_store
     |       |-- error_count
     |       |-- threshold_limit
     |-- monarch_timeout
     |-- northbridge
     |   |-- dram
     |   |   |-- error_count
     |   |   |-- interrupt_enable
     |   |   |-- threshold_limit
     |   |-- ht_links
     |   |   |-- error_count
     |   |   |-- interrupt_enable
     |   |   |-- threshold_limit
     |   |-- l3_cache
     |       |-- error_count
     |       |-- interrupt_enable
     |       |-- threshold_limit
    ...

It is tested on all our families >= K8.
