  RISC-V: Don't check text_mutex during stop_machine (2023-03-09 14:58:51 -0800)

----------------------------------------------------------------
RISC-V Fixes for 6.3-rc2

* RISC-V architecture-specific ELF attributes have been disabled in the
  kernel builds.
* A fix for a locking failure while during errata patching that
  manifests on SiFive-based systems.
* A fix for a KASAN failure during stack unwinding.
* A fix for some lockdep failures during text patching.

----------------------------------------------------------------
There's a handful of failures with this alone, but they're all merge window
regressions from other trees and have been fixed in master already.  I figured
it would be saner to just keep this on rc1 rather than try and pull anything
else in.
