- Add support for control flow integrity for userspace processes. This is based on the standard RISC-V ISA extensions Zicfiss and Zicfilp - Improve ptrace behavior regarding vector registers, and add some selftests - Optimize our strlen() assembly - Enable the ISO-8859-1 code page as built-in, similar to ARM64, for EFI volume mounting - Clean up some code slightly, including defining copy_user_page() as copy_page() rather than memcpy(), aligning us with other architectures; and using max3() to slightly simplify an expression in riscv_iommu_init_check() -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEElRDoIDdEz9/svf2Kx4+xDQu9KksFAmmOYpYACgkQx4+xDQu9 KkvzOQ/9Fq8ZxWgYofhTPtw9/vps3avheOHlEoRrBWYfn1VkTRPAcbUULL4PGXwg dnVFEl3AcrpOFikIthbukklLeLoOnUshZJBU25zY5h0My1jb63V1//gEwJR6I0dg +V+GJmfzc4+YVaHK6UFdn7j3GgKUbTC7xXRMuGEriAzKPnm3AXAjh94wMNx6depv Li3IXRoZT/HvqIAyfeAoM9STwOzJtE3Sc6fXABkzsIbNTjjdgIqoRSsQsKY10178 z6ox/sVStnLmVaMbOd/ZVN0J70JRDsvK0TC0/13K1ESUbnVia9a3bPIxLRmSapKC wXnwAuSeevtFshGGyd5LZO0QQGxzG1H63Gky2GRoh8bTQbd2tQcfQzANdnPkBAQS j2aOiSsiUQeNZqfZAfEBwRd27GXRYlKb/MpgCZKUH+ZO9VG6QaD3VGvg17/Caghy nVdbBQ81ZV9tkz9EMN0vt2VJHmEqARh88w619laHjg+ioPTG4/UIDPzskt1I+Fgm Y6NQLeFyfaO3RKKDYWGPcY7fmWQI9V8MECHOvyVI4xJcgqAbqnfsgytjuiFbrfRo fTvpuB7kvltBZ180QSB79xj0sWGFTWR02MeWy3uOaLZz2eIm2ZTZbMUSgNYR0ldG L3y7CEkTkoVF1ijYgAfuMgptk3Yf0dpa66D9HUo947wWkNrW5ds= =4fTk -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-7.0-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V updates from Paul Walmsley: - Add support for control flow integrity for userspace processes.
