CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Some initialization errors are reported with the existing OCTEON EDAC

Fix the errors and add multiple controllers if present.
Signed-off-by: NDavid Daney <david.daney@cavium.com>

Drivers for EDAC on Cavium.  Supported subsystems are:

 o CPU primary caches.  These are parity protected only, so only error
   reporting.
 o Second level cache - ECC protected, provides SECDED.
 o Memory: ECC / SECDEC if used with suitable DRAM modules.  The driver will
   will only initialize if ECC is enabled on a system so is safe to run on
   non-ECC memory.
 o PCI: Parity error reporting

Since it is very hard to test this sort of code the implementation is very
conservative and uses polling where possible for now.

Having the functional unit names in each bank decode is only misleading
as this code supports multiple families and there's no guarantee the

The driver is currently filling data in a wrong way, on drivers
for csrows-based memory controller, when the first layer is a
csrow.

This is not easily to notice, as, in general, memories are
filed in dual, interleaved, symetric mode, as very few memory
controllers support asymetric modes.

While digging into a bug for i82795_edac driver, the asymetric
mode there is now working, allowing us to fill the machine with
4x1GB ranks at channel 0, and 2x512GB at channel 1:

Channel 0 ranks:
EDAC DEBUG: i82975x_init_csrows: DIMM A0: from page 0x00000000 to 0x0003ffff (size: 0x00040000 pages)
EDAC DEBUG: i82975x_init_csrows: DIMM A1: from page 0x00040000 to 0x0007ffff (size: 0x00040000 pages)
EDAC DEBUG: i82975x_init_csrows: DIMM A2: from page 0x00080000 to 0x000bffff (size: 0x00040000 pages)
EDAC DEBUG: i82975x_init_csrows: DIMM A3: from page 0x000c0000 to 0x000fffff (size: 0x00040000 pages)

Channel 1 ranks:
EDAC DEBUG: i82975x_init_csrows: DIMM B0: from page 0x00100000 to 0x0011ffff (size: 0x00020000 pages)
EDAC DEBUG: i82975x_init_csrows: DIMM B1: from page 0x00120000 to 0x0013ffff (size: 0x00020000 pages)

Instead of properly showing the memories as such, before this patch, it
shows the memory layout as:

          +-----------------------------------+
          |                mc0                |
          |  csrow0   |  csrow1   |  csrow2   |
----------+-----------------------------------+
channel1: |  1024 MB  |  1024 MB  |   512 MB  |
channel0: |  1024 MB  |  1024 MB  |   512 MB  |
----------+-----------------------------------+

as if both channels were symetric, grouping the DIMMs on a wrong
layout.

After this patch, the memory is correctly represented.
So, for csrows at layers[0], it shows:

          +-----------------------------------------------+
          |                      mc0                      |
          |  csrow0   |  csrow1   |  csrow2   |  csrow3   |
----------+-----------------------------------------------+
channel1: |   512 MB  |   512 MB  |     0 MB  |     0 MB  |
channel0: |  1024 MB  |  1024 MB  |  1024 MB  |  1024 MB  |
----------+-----------------------------------------------+

For csrows at layers[1], it shows:

        +-----------------------+
        |          mc0          |
        | channel0  | channel1  |
--------+-----------------------+
csrow3: |  1024 MB  |     0 MB  |
csrow2: |  1024 MB  |     0 MB  |
--------+-----------------------+
csrow1: |  1024 MB  |   512 MB  |
csrow0: |  1024 MB  |   512 MB  |
--------+-----------------------+

So, no matter of what comes first, the information between
channel and csrow will be properly represented.

If none of the elements in scrubrates[] matches, this loop will cause
__amd64_set_scrub_rate() to incorrectly use the n+1th element.

As the function is designed to use the final scrubrates[] element in the
case of no match, we can fix this bug by simply terminating the array
search at the n-1th element.

Sandy bridge EDAC is calculating the memory size with overflow.
Basically, the size field and the integer calculation is using 32 bits.
More bits are needed, when the DIMM memories have high density.

The net result is that memories are improperly reported there, when
high-density DIMMs are used:

EDAC DEBUG: in drivers/edac/sb_edac.c, line at 591: mc#0: channel 0, dimm 0, -16384 Mb (-4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800
EDAC DEBUG: in drivers/edac/sb_edac.c, line at 591: mc#0: channel 1, dimm 0, -16384 Mb (-4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800

As the number of pages value is handled at the EDAC core as unsigned
ints, the driver shows the 16 GB memories at sysfs interface as 16760832
MB! The fix is simple: calculate the number of pages as unsigned 64-bits
integer.

After the patch, the memory size (16 GB) is properly detected:

EDAC DEBUG: in drivers/edac/sb_edac.c, line at 592: mc#0: channel 0, dimm 0, 16384 Mb (4194304 pages) bank: 8, rank: 2, row: 0x10000, col: 0x800

Fix potential NULL pointer dereference in edac_unregister_sysfs() on
system boot introduced in 3.6-rc1.

Since commit 7a623c03 ("edac: rewrite the sysfs code to use struct
device") edac_mc_alloc() no longer initializes embedded kobjects in
struct mem_ctl_info.  Therefore edac_mc_free() can no longer simply
decrement a kobject reference count to free the allocated memory unless
the memory controller driver module had also called edac_mc_add_mc().

Now edac_mc_free() will check if the newly embedded struct device has
been registered with sysfs before using either the standard device
release functions or freeing the data structures itself with logic
pulled out of the error path of edac_mc_alloc().

The BUG this patch resolves for me:

and that code block seem to mess things up in several ways (double free, memory
leak, out-of-bound reads etc.):

L422: The iterator "chn" and bound "tot_channels" are totally wrong. Should be
      "row" and "tot_csrows" respectively. Which means either memory leak, or
      out-of-bound reads (which if does not trigger an immediate page fault
      error, will further lead to kfree() on random addresses).

L425: The inner loop is reusing the same iterator "chn" as the outer loop,
      which could lead to premature end of the outer loop, and hence memory leak.

L429: The array index 'i' in mci->csrows[i] is a temporary value used in
      previous loops, and won't change at all in the current loop. Which
      means either out-of-bound read and possibly kfree(random number), or the
      same mci->csrows[i] get freed once and again, and possibly double free
      for the kfree(csr) in L427.

L426/L427: a kfree(csr->channels) is needed in between to avoid leaking the memory.

The buggy code was introduced by commit de3910eb ("edac: change the mem
allocation scheme to make Documentation/kobject.txt happy") in the 3.6-rc1
merge window. Fix it by freeing up resources in this order:

  free csrows[i]->channels[j]
  free csrows[i]->channels
  free csrows[i]
  free csrows

We unified the Freescale pci/pcie initialization by changing the fsl_pci
to a platform driver. In previous PCI code architecture the initialization
routine is called at board_setup_arch stage. Now the initialization is done
in probe function which is architectural better. Also It's convenient for
adding PM support for PCI controller in later patch.

Now we registered pci controllers as platform devices. So we combine two
initialization code as one platform driver.

Convert delayed_work users doing cancel_delayed_work() followed by
queue_delayed_work() to mod_delayed_work().

Most conversions are straight-forward.  Ones worth mentioning are,

* drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always
  use mod_delayed_work() and cancel loop in
  edac_mc_reset_delay_period() is dropped.

* drivers/platform/x86/thinkpad_acpi.c: No need to remember whether
  watchdog is active or not.  @fan_watchdog_active and related code
  dropped.

* drivers/power/charger-manager.c: Seemingly a lot of
  delayed_work_pending() abuse going on here.
  [delayed_]work_pending() are unsynchronized and racy when used like
  this.  I converted one instance in fullbatt_handler().  Please
  conver the rest so that it invokes workqueue APIs for the intended
  target state rather than trying to game work item pending state
  transitions.  e.g. if timer should be modified - call
  mod_delayed_work(), canceled - call cancel_delayed_work[_sync]().

* drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling()
  simplified.  Note that round_jiffies() calls in this function are
  meaningless.  round_jiffies() work on absolute jiffies not delta
  delay used by delayed_work.

v2: Tomi pointed out that __cancel_delayed_work() users can't be
    safely converted to mod_delayed_work().  They could be calling it
    from irq context and if that happens while delayed_work_timer_fn()
    is running, it could deadlock.  __cancel_delayed_work() users are
    dropped.
