This contains what I hope are the last RISC-V changes to go into 4.15. I know it's a bit last minute, but I think they're all fairly small changes: * SR_* constants have been renamed to match the latest ISA specification. * Some CONFIG_MMU #ifdef cruft has been removed. We've never supported !CONFIG_MMU. * __NR_riscv_flush_icache is now visible to userspace. We were hoping to avoid making this public in order to force userspace to call the vDSO entry, but it looks like QEMU's user-mode emulation doesn't want to emulate a vDSO. In order to allow glibc to fall back to a system call when the vDSO entry doesn't exist we're just * Our defconfig is no long empty. This is another one that just slipped through the cracks. The defconfig isn't perfect, but it's at least close to what users will want for the first RISC-V development board. Getting closer is kind of splitting hairs here: none of the RISC-V specific drivers are in yet, so it's not like things will boot out of the box. The only one that's strictly necessary is the __NR_riscv_flush_icache change, as I want that to be part of the public API starting from our first kernel so nobody has to worry about it. The others are nice to haves, but they seem sane for 4.15 to me. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEAM520YNJYN/OiG3470yhUCzLq0EFAlpU/UcTHHBhbG1lckBk YWJiZWx0LmNvbQAKCRDvTKFQLMurQdy5D/9fcTwXTk98U2gSoR4Dv25tztqbNMhw +Lae5EeIqAaPI4xfyLGldJe0BWAJaouZWIY5xkB5JWzsdYPx/jYgC+SbwI/3aGVy VjcU0d4haZtz2kdm0Y0ZKIGg91vDlULoVvcxrM8Jff0gDmyKoT1OjwKpt3esyhmN Vc+iC0FxtJow/xIaFlnPa42qh/pFkcLDmmY/Im6N8IEcyHBT6vCDnD3CgCFY/hdu 9vcWJDvFBj4SFwL8y+ajspQ4tPzDt4Ko+3NLxtEv+19y3NEgLm+shbxv/J8AVO8O BvBr51QfggM2rAqGzCa4nEZZR7Roxgg9bJVQARXyzX1tUhtBEz9+eUArJ0tzMtbx GyXYY5NwyupDJ/MA9yn+GqYlLNnS2yL2y0zIBJehi/37+KpAFtH/cRnA58sXViqw IKGhKW7JCGU3/xyW+RtuY3N5urU18+qE4CZRLtI5QN0QRcTWLhqqQvQRud86HqqD g4KPo6g9Z6Ak9Xu81n/liIExp3Vp2kpQUts1lCF1D+4WYRwpb4Mqy4HiOCSf/OO2 wOuX5HY+tbS8yvupgYjszTXaYDn35RoGkcjK9o1Lkq9RgI5kzHDyaQrSK/c/oAzn A7cJ2z7dBaV0W4O7R+2SJ2k9DHw1db/WVf19pKVjSi5osSoUds5w1YxHK25cSBUz +47LVCgkQI/Scw== =PhUK -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-4.15-rc8_cleanups' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/linux Pull RISC-V updates from Palmer Dabbelt: "This contains what I hope are the last RISC-V changes to go into 4.15.
