riscv: disable stack-protector for vDSO (2020-08-04 15:02:49 -0700)

----------------------------------------------------------------
RISC-V Patches for the 5.9 Merge Window, Part 1

We have a lot of new kernel features for this merge window:

* ARCH_SUPPORTS_ATOMIC_RMW, to allow OSQ locks to be enabled.
* The ability to enable NO_HZ_FULL
* Support for enabling kcov, kmemleak, stack protector, and VM debugging.
* JUMP_LABEL support.

There are also a handful of cleanups.

next points out a trivial Kconfig merge conflict. I don't see any way to have
done this better: the symbols are sorted, it just happens that
HAVE_COPY_THREAD_TLS was in the middle of two new symbols. In case it helps
any, here's a pretty current conflict resolution:
