Subject: EDAC/wq: Remove unneeded flush_workqueue()

destroy_workqueue() already takes care of flushing the workqueue so
there is no need to flush it explicitly.

Subject: EDAC/mc: Drop duplicated dimm->nr_pages debug printout

The duplicated edac_dbg()-based dimm->nr_pages print was introduced in

  6e84d359b2be ("edac_mc: Cleanup per-dimm_info debug messages").

The duplicated line can be found even in the commit message text:

  [ 1011.380101] EDAC DEBUG: edac_mc_dump_dimm:   dimm->nr_pages = 0x40000
  [ 1011.380103] EDAC DEBUG: edac_mc_dump_dimm:   dimm->grain = 8
  [ 1011.380104] EDAC DEBUG: edac_mc_dump_dimm:   dimm->nr_pages = 0x40000

Drop the second edac_dbg() call.

Subject: EDAC/skx_common: Use driver decoder first

The performance of driver decoder[1] is better than the performance
of firmware decoder[2], especially on frequent correctable errors.

So use the driver decoder first, fall back to firmware decoder if
the driver decoder is unavailable. Also rename the function pointer
skx_decode to driver_decode (better name to contrast with adxl_decode).

[1] Decode errors by extracting error information from registers of
    memory controllers and/or MCA bank registers.

[2] Decode errors by calling ACPI DSM methods.

Subject: EDAC/i10nm: Add driver decoder for Ice Lake and Tremont CPUs

Current i10nm_edac only supports firmware decoder (ACPI DSM methods).
MCA bank registers of Ice Lake or Tremont CPUs contain the information
to decode DDR memory errors. To get better decoding performance, add
the driver decoder (decoding DDR memory errors via extracting error
information from MCA bank registers) for Ice Lake and Tremont CPUs.

Commit

  4de78c6877ec ("drivers/edac: mod PCI poll names"),

renamed the respective variables and accessors but left the old accessor
declarations edac_get_log_ce(), edac_get_log_ue(), edac_get_poll_msec()
and edac_get_panic_on_ue() in place. Remove them.

Subject: EDAC/ppc_4xx: Reorder symbols to get rid of a few forward
 declarations
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When moving the definition of ppc4xx_edac_driver further down, the
forward declarations can just be dropped.

Do this to reduce needless line repetition.

Subject: EDAC/skx_common: Add ChipSelect ADXL component

Each pseudo channel of HBM has its own retry_rd_err_log registers.
The bit 0 of ChipSelect ADXL component encodes the pseudo channel
number of HBM memory. So add ChipSelect ADXL component to get HBM
pseudo channel number.

Subject: x86/sb_edac: Add row column translation for Broadwell

The sb_edac driver lacks translation for DIMM internal address.

Add memory address translation for row/column/bank/bank_group
on Broadwell.
