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. 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this series, we still have a few architectures without mainline gcc support: - unicore32 and hexagon both have very outdated gcc releases, but the maintainers promised to work on providing something newer.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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJawdL2AAoJEGCrR//JCVInuH0P/RJAZh1nTD+TR34ZhJq2TBoo PgygwDU7Z2+tQVU+EZ453Gywz9/NMRFk1RWAZqrLix4ZtyIMvC6A1qfT2yH1Y7Fb Qh6tccQeLe4ezq5u4S/46R/fQXu3Txr92yVwzJJUuPyU0arF9rv5MmI8e6p7L1en yb74kSEaCe+/eMlsEj1Cc1dgthDNXGKIURHkRsILoweysCpesjiTg4qDcL+yTibV FP2wjVbniKESMKS6qL71tiT5sexvLsLwMNcGiHPj94qCIQuI7DLhLdBVsL5Su6gI sbtgv0dsq4auRYAbQdMaH1hFvu6WptsuttIbOMnz2Yegi2z28H8uVXkbk2WVLbqG ZESUwutGh8MzOL2RJ4jyyQq5sfo++CRGlfKjr6ImZRv03dv0pe/W85062cK5cKNs cgDDJjGRorOXW7dyU6jG2gRqODOQBObIv3w5efdq5OgzOWlbI4EC+Y5u1Z0JF/76 pSwtGXA6YhwC+9LLAlnVTHG+yOwuLmAICgoKcTbzTVDKA2YQZG/cYuQfI5S1wD8e X6urPx3Md2GCwLXQ9mzKBzKZUpu/Tuhx0NvwF4qVxy6x1PELjn68zuP7abDHr46r 57/09ooVN+iXXnEGMtQVS/OPvYHSa2NgTSZz6Y86lCRbZmUOOlK31RDNlMvYNA+s 3iIVHovno/JuJnTOE8LY =fQ8z -----END PGP SIGNATURE----- Merge tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic 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.
