Merge tag 'riscv-for-linus-6.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V fixes from Palmer Dabbelt:

 - A fix for an __{get,put}_kernel_nofault to avoid an uninitialized
   value causing spurious failures

 - compat_vdso.so.dbg is now installed to the standard install location

 - A fix to avoid initializing PERF_SAMPLE_BRANCH_*-related events, as
   they aren't supported and will just later fail

 - A fix to make AT_VECTOR_SIZE_ARCH correct now that we're providing
   AT_MINSIGSTKSZ

 - pgprot_nx() is now implemented, which fixes vmap W^X protection

 - A fix for the vector save/restore code, which at least manifests as
   corrupted vector state when a signal is taken

 - A fix for a race condition in instruction patching

 - A fix to avoid leaking the kernel-mode GP to userspace, which is a
   kernel pointer leak that can be used to defeat KASLR in various ways

 - A handful of smaller fixes to build warnings, an overzealous printk,
   and some missing tracing annotations
