Linus Torvalds 261b8e89b6 RISC-V Fixes for 6.9-rc3

* 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.
