Merge tag 'riscv-for-linus-6.16-mw1' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V updates from Palmer Dabbelt:

 - Support for the FWFT SBI extension, which is part of SBI 3.0 and a
   dependency for many new SBI and ISA extensions

 - Support for getrandom() in the VDSO

 - Support for mseal

 - Optimized routines for raid6 syndrome and recovery calculations

 - kexec_file() supports loading Image-formatted kernel binaries

 - Improvements to the instruction patching framework to allow for
   atomic instruction patching, along with rules as to how systems need
   to behave in order to function correctly

 - Support for a handful of new ISA extensions: Svinval, Zicbop, Zabha,
   some SiFive vendor extensions

 - Various fixes and cleanups, including: misaligned access handling,
   perf symbol mangling, module loading, PUD THPs, and improved uaccess
   routines
