Merge tag 'riscv-for-linus-6.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux
Pull RISC-V fixes from Palmer Dabbelt: - A fix for a build warning in the jump_label code - One of the git://github -> https://github cleanups, for the SiFive drivers - A fix for the kasan initialization code, this still likely warrants some cleanups but that's a bigger problem and at least this fixes the crashes in the short term - A pair of fixes for extension support detection on mixed LLVM/GNU toolchains - A fix for a runtime warning in the /proc/cpuinfo code * tag 'riscv-for-linus-6.1-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: RISC-V: Fix /proc/cpuinfo cpumask warning riscv: fix detection of toolchain Zihintpause support riscv: fix detection of toolchain Zicbom support riscv: mm: add missing memcpy in kasan_init MAINTAINERS: git://github.com -> https://github.com for sifive riscv: jump_label: mark arguments as const to satisfy asm constraints
