Pul removal of obsolete architecture ports from Arnd Bergmann:
"This removes the entire architecture code for blackfin, cris, frv,
m32r, metag, mn10300, score, and tile, including the associated device
drivers.
I have been working with the (former) maintainers for each one to
ensure that my interpretation was right and the code is definitely
unused in mainline kernels. Many had fond memories of working on the
respective ports to start with and getting them included in upstream,
but also saw no point in keeping the port alive without any users.
In the end, it seems that while the eight architectures are extremely
different, they all suffered the same fate: There was one company in
charge of an SoC line, a CPU microarchitecture and a software
ecosystem, which was more costly than licensing newer off-the-shelf
CPU cores from a third party (typically ARM, MIPS, or RISC-V). It
seems that all the SoC product lines are still around, but have not
used the custom CPU architectures for several years at this point. In
contrast, CPU instruction sets that remain popular and have actively
maintained kernel ports tend to all be used across multiple licensees.
[ See the new nds32 port merged in the previous commit for the next
generation of "one company in charge of an SoC line, a CPU
microarchitecture and a software ecosystem" - Linus ]
The removal came out of a discussion that is now documented at
https://lwn.net/Articles/748074/. Unlike the original plans, I'm not
marking any ports as deprecated but remove them all at once after I
made sure that they are all unused. Some architectures (notably tile,
mn10300, and blackfin) are still being shipped in products with old
kernels, but those products will never be updated to newer kernel
releases.
After this series, we still have a few architectures without mainline
gcc support:
- unicore32 and hexagon both have very outdated gcc releases, but the
maintainers promised to work on providing something newer. At least
in case of hexagon, this will only be llvm, not gcc.
- openrisc, risc-v and nds32 are still in the process of finishing
their support or getting it added to mainline gcc in the first
place. They all have patched gcc-7.3 ports that work to some
degree, but complete upstream support won't happen before gcc-8.1.
Csky posted their first kernel patch set last week, their situation
will be similar
[ Palmer Dabbelt points out that RISC-V support is in mainline gcc
since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]"
This really says it all:

The Tile architecture is obsolete and getting removed from the kernel,
this driver appears to only be used there, and not on the ARM based
successors (Tile-Mx, BlueField), so we should remove it as well.

Somehow we ended up with two separate arrays of strings to describe the
"enum mem_type" values.
In edac_mc.c we have an exported list edac_mem_types[] that is used
by a couple of drivers in debug messaged.
In edac_mc_sysfs.c we have a private list that is used to display
values in:
/sys/devices/system/edac/mc/mc*/dimm*/dimm_mem_type
/sys/devices/system/edac/mc/mc*/csrow*/mem_type
This list was missing a value for MEM_LRDDR3.
The string values in the two lists were different :-(
Combining the lists, I kept the values so that the sysfs output
will be unchanged as some scripts may depend on that.

Commit
3286d3eb906c ("EDAC, sb_edac: Drop NUM_CHANNELS from 8 back to 4")
decreased NUM_CHANNELS from 8 to 4, but this is not enough for Knights
Landing which supports up to 6 channels.
This caused out-of-bounds writes to pvt->mirror_mode and pvt->tolm
variables which don't pay critical role on KNL code path, so the memory
corruption wasn't causing any visible driver failures.
The easiest way of fixing it is to change NUM_CHANNELS to 6. Do that.
An alternative solution would be to restructure the KNL part of the
driver to 2MC/3channel representation.

Currently, bank 4 is reserved on Fam17h, so we chose not to initialize
bank 4 in the smca_banks array. This means that when we check if a bank
is initialized, like during boot or resume, we will see that bank 4 is
not initialized and try to initialize it.
This will cause a call trace, when resuming from suspend, due to
rdmsr_*on_cpu() calls in the init path. The rdmsr_*on_cpu() calls issue
an IPI but we're running with interrupts disabled. This triggers:
WARNING: CPU: 0 PID: 11523 at kernel/smp.c:291 smp_call_function_single+0xdc/0xe0
...
Reserved banks will be read-as-zero, so their MCA_IPID register will be
zero. So, like the smca_banks array, the threshold_banks array will not
have an entry for a reserved bank since all its MCA_MISC* registers will
be zero.
Enumerate a "Reserved" bank type that matches on a HWID_MCATYPE of 0,0.
Use the "Reserved" type when checking if a bank is reserved. It's
possible that other bank numbers may be reserved on future systems.
Don't try to find the block address on reserved banks.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

For several reasons, it is desirable to use {READ,WRITE}_ONCE() in
preference to ACCESS_ONCE(), and new code is expected to use one of the
former. So far, there's been no reason to change most existing uses of
ACCESS_ONCE(), as these aren't currently harmful.
However, for some features it is necessary to instrument reads and
writes separately, which is not possible with ACCESS_ONCE(). This
distinction is critical to correct operation.
It's possible to transform the bulk of kernel code using the Coccinelle
script below. However, this doesn't handle comments, leaving references
to ACCESS_ONCE() instances which have been removed. As a preparatory
step, this patch converts the Altera EDAC code and comments to use
{READ,WRITE}_ONCE() consistently.

When figuring out the size of the DIMMs and the cluster mode is SNC2 or SNC4 the
current algorithm ignores the contribution of some of the channels resulting in
EDAC never knowing of the existence of some DIMMs attached to such channels (thus
sysfs is not populated).
Instead of selectively iterating from 0 to interlv_ways when looking for all the
participants in the interleave, do an exhaustive search and iterate from 0 to
KNL_MAX_CHANNELS. The algorithm is already smart enough to consider participants
only one time.
This works fine in all KNL cluster modes and even when there are missing DIMMs
as the contribution of those channels is 0.

Yi Zhang reported the following failure on a 2-socket Haswell (E5-2603v3)
server (DELL PowerEdge 730xd):
EDAC sbridge: Some needed devices are missing
EDAC MC: Removed device 0 for sb_edac.c Haswell SrcID#0_Ha#0: DEV 0000:7f:12.0
EDAC MC: Removed device 1 for sb_edac.c Haswell SrcID#1_Ha#0: DEV 0000:ff:12.0
EDAC sbridge: Couldn't find mci handler
EDAC sbridge: Couldn't find mci handler
EDAC sbridge: Failed to register device with error -19.
The refactored sb_edac driver creates the IMC1 (the 2nd memory
controller) if any IMC1 device is present. In this case only
HA1_TA of IMC1 was present, but the driver expected to find
HA1/HA1_TM/HA1_TAD[0-3] devices too, leading to the above failure.
The document [1] says the 'E5-2603 v3' CPU has 4 memory channels max. Yi
Zhang inserted one DIMM per channel for each CPU, and did random error
address injection test with this patch:
4024 addresses fell in TOLM hole area
12715 addresses fell in CPU_SrcID#0_Ha#0_Chan#0_DIMM#0
12774 addresses fell in CPU_SrcID#0_Ha#0_Chan#1_DIMM#0
12798 addresses fell in CPU_SrcID#0_Ha#0_Chan#2_DIMM#0
12913 addresses fell in CPU_SrcID#0_Ha#0_Chan#3_DIMM#0
12674 addresses fell in CPU_SrcID#1_Ha#0_Chan#0_DIMM#0
12686 addresses fell in CPU_SrcID#1_Ha#0_Chan#1_DIMM#0
12882 addresses fell in CPU_SrcID#1_Ha#0_Chan#2_DIMM#0
12934 addresses fell in CPU_SrcID#1_Ha#0_Chan#3_DIMM#0
106400 addresses were injected totally.
The test result shows that all the 4 channels belong to IMC0 per CPU, so
the server really only has one IMC per CPU.
In the 1st page of chapter 2 in datasheet [2], it also says 'E5-2600 v3'
implements either one or two IMCs. For CPUs with one IMC, IMC1 is not
used and should be ignored.
Thus, do not create a second memory controller if the key HA1 is absent.

The ghes_edac driver was introduced in 2013 [1], but it has not been
enabled by any distro yet. This driver obtains error info from firmware
interfaces (APEI), which are not properly implemented on many platforms,
as the driver says on load:
This EDAC driver relies on BIOS to enumerate memory and get error
reports. Unfortunately, not all BIOSes reflect the memory layout
correctly. So, the end result of using this driver varies from vendor
to vendor. If you find incorrect reports, please contact your hardware
vendor to correct its BIOS.
To get out from this situation, add a platform check to selectively
enable the driver on platforms that are known to have proper APEI
firmware implementation.
"ghes_edac.force_load=1" skips this platform check.

We're enumerating the DIMMs through a DMI walk and since we can't get
any more detailed topological information about which DIMMs belong to
which memory controller, convert it to a single, logical controller
which contains all the DIMMs.
The error reporting path from GHES ghes_edac_report_mem_error() doesn't
get called in NMI context but add a warning about it to catch any
changes in the future as if so, our locking scheme will be insufficient
then.

On Deverton server, the P2SB PCI device (DEV:1F, FUN:1) is used by multiple

the commit
9424693035a5 ("i2c: i801: Create iTCO device on newer Intel PCHs")
unconditionally hid the P2SB PCI device wrongly) it will make the
pnd2_edac driver read out an invalid BAR value of 0xffffffff and then
fail on ioremap().
Therefore, store the presence state of P2SB PCI device before unhiding
it for reading BAR and restore the presence state after reading BAR.

Basically, there are full memory mirroring and address range partial
memory mirroring (supported by Haswell EX and Broadwell EX) modes.
a) In full memory mirroring, the memory behind each memory controller
is mirrored, i.e. the memory is split into two identical mirrors
(primary and secondary), half of the memory is reserved for redundancy.
b) In address range partial memory mirroring, the memory size (range)
of primary and secondary behind each memory controller can be user
defined by the TAD0 register. The rest of memory ranges defined by
TAD1/TAD2/... in that memory controller are non-mirrored.
For more detail on memory mirroring, see the following link written by Tony Luck:
https://01.org/lkp/blogs/tonyluck/2016/address-range-partial-memory-mirroring-linux
Currently the sb_edac driver only supports address decoding in full
memory mirroring and non-mirroring modes. In address range partial
memory mirroring mode, it may fail to decode an address that falls in a
non-mirroring area (the following was one of this kind of failed logs).
