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this series, we still have a few architectures without mainline gcc support: - unicore32 and hexagon both have very outdated gcc releases, but the maintainers promised to work on providing something newer.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: 2498 files changed, 95 insertions(+), 467668 deletions(-) * tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: (74 commits) MAINTAINERS: UNICORE32: Change email account staging: iio: remove iio-trig-bfin-timer driver tty: hvc: remove tile driver tty: remove bfin_jtag_comm and hvc_bfin_jtag drivers serial: remove tile uart driver serial: remove m32r_sio driver serial: remove blackfin drivers serial: remove cris/etrax uart drivers usb: Remove Blackfin references in USB support usb: isp1362: remove blackfin arch glue usb: musb: remove blackfin port usb: host: remove tilegx platform glue pwm: remove pwm-bfin driver i2c: remove bfin-twi driver spi: remove blackfin related host drivers watchdog: remove bfin_wdt driver can: remove bfin_can driver mmc: remove bfin_sdh driver input: misc: remove blackfin rotary driver input: keyboard: remove bf54x driver ...

edac: remove tile driver

2018-03-26T13:56:17Z

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. Acked-by: Borislav Petkov Acked-by: Mauro Carvalho Chehab Signed-off-by: Arnd Bergmann

EDAC, sb_edac: Remove variable length array usage

2018-03-17T04:24:55Z

In preparation for enabling -Wvla, remove VLA and replace it with a fixed-length array instead. Also, remove max_interleave as it is no longer needed.

EDAC, skx_edac: Detect non-volatile DIMMs

2018-03-14T23:33:55Z

This just covers the topology function of the EDAC driver. We locate which DIMM slots are populated with NVDIMMs and query the NFIT and SMBIOS tables to get the size.

EDAC: Drop duplicated array of strings for memory type names

2018-03-14T11:20:16Z

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.

EDAC, layerscape: Allow building for LS1021A

2018-02-27T13:57:47Z

The LS1021A has a memory controller supported by this driver. It builds just fine, and I've done some rudimentary testing using the error injection facility, which suggests that it is indeed working.

EDAC, sb_edac: Fix out of bound writes during DIMM configuration on KNL

2018-02-23T11:05:37Z

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.
