  riscv: Sparse-Memory/vmemmap out-of-bounds fix (2024-02-29 12:24:31 -0800)

----------------------------------------------------------------
RISC-V Fixes for 6.8-rc7

* A fix for detecting ".option arch" support on not-yet-released LLVM
  builds.
* A fix for a missing TLB flush when modifying non-leaf PTEs.
* A handufl of fixes for T-Head custom extensions.
* A fix for systems with the legacy PMU, that manifests as a crash on
  kernels built without SBI PMU support.
* A fix for systems that clear *envcfg on suspend, which manifests as
  cbo.zero trapping after resume.
* A pair of fixes for Svnapot systems, including removing Svnapot
  support for huge vmalloc/vmap regions.
