* .rodata is no longer linkd into PT_DYNAMIC, it was not supposed to be there in the first place and resultst in invalid (but unused) entries. This manifests as at least warnings in llvm-readelf. * A fix for runtime constants with all-0 upper 32-bits. This should only manifest on MMU=n kernels. * A fix for context save/restore on systems using the T-Head vector extensions. * A fix for a conflicting "+r"/"r" register constraint in the VDSO getrandom syscall wrapper, which is undefined behavior in clang. * A fix for a missing register clobber in the RVV raid6 implementation. This manifests as a NULL pointer reference on some compilers, but could trigger in other ways. * Misaligned accesses from userspace at faulting addresses are now handled correctly. * A fix for an incorrect optimization that allowed access_ok() to mark invalid addresses as accessible, which can result in userspace triggering BUG()s. * A few fixes for build warnings, and an update to Drew's email address. -----BEGIN PGP SIGNATURE----- iQJNBAABCAA3FiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAmhe80kZHHBhbG1lcmRh YmJlbHRAZ29vZ2xlLmNvbQAKCRAuExnzX7sYicV6EACT/5384tdpYSQ6WQ4K2mT2 XxPbrYTJ4jrhZMugnfe1LHBokeBGoGPRK11Dr/PyNJ71oeeDF7opv0kxAfqsiOO3 QrwUE/4zhGgEzs7Z6D8UgYiqVDfb4aMU+oZ0qIfy+r+cB4F9M65TIejdVj99V6Hu V9cjJ4ABM9KfaZhD5BvoqflblYtwuSg/VYsUmZH6aolDyadzTy4rWcPk1jdFJDQt tIEsXjc92KNAKGSFe8DDZjjhM216Th/nUsZcxI2DLRQjjHPNEthkAgLNltQGocU9 gJ8U3IqfazgnqcZAlrr7BXlWYlBFH/wGXVsxuBL5LPov19RcTkjl2PWH7T08yyuv lCGXrfkz3hSu+Sa9A40w4LptrKNWUEFJztaPkQ68gn1ZQP7KB/rsWp+82dCqhT35 RNxmSznLyTsHFRXR2n9fZrWX/F/LwxY7vaH7cTZUDkMHI8F7WP/3tlihxPCQaUHD dIb+osch8puxG3YjO7H99WrpJamNNw3+L1l2lXtXTRmXdxE+x7fyatmHX98mY8IC 7NXGOdNNIEvv4i9vzSphYQHBOT3tBVfz40z878qfSL3xYHG3ZLMIsWuynaWDMI73 QprwAPmdFxdmJrHyIY6gIiyrscNHz5WLMjkG4K+jXlsBBmDxJMAY5zzNdFoeUVDz tjnDY4DYc4fCnteKSA/hpw== =42TO -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-5.16-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V Fixes for 5.16-rc4 - .rodata is no longer linkd into PT_DYNAMIC.

Linux kernel
There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first.
In order to build the documentation, use make htmldocs or
make pdfdocs. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
