  riscv: process: Fix kernel gp leakage (2024-04-04 12:35:05 -0700)

----------------------------------------------------------------
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.
