Linus,
Please pull the following RISC-V updates for v7.2-rc6. Nothing too
notable here, I think. Most likely we'll send one more fixes PR
before the v7.3 merge window opens.

riscv: vdso: Only try to install vDSO when present (2026-07-29 17:55:17 -0600)
----------------------------------------------------------------
RISC-V updates for v7.2-rc6
- Fix swiotlb initialization on systems where DRAM is located above
4GiB (such as the Tenstorrent Blackhole cards)
- Fix an out-of-bounds access in the memory hot-remove code that can
occur on Sv39 and Sv48 systems
- Avoid oopsing during boot if the SBI component of the unaligned
access performance checking code loses a race against __init
function freeing
- Avoid attempting to install the debug-enabled vDSO when it shouldn't
be built due to !CONFIG_MMU
- Avoid some sparse warnings by adding missing __iomem notations
in get_cycles{,_hi}()
- Drop an unnecessary runtime warning in the SiFive errata handler
