grsec - Denied RWX mmap of /usr/lib32/mesa/libGL.so.1.2.0

Team Fortress is crashing on linux-grsec. In the past, the only flag I had enabled for hl2_linux was "m" (disabled mprotect), but now I have to do "em" otherwise TF2 will crash the entire system.

[amarildo@amarildo ~]$ journalctl | grep /usr/lib32/mesa/libGL.so.1.2.0
Mar 25 14:36:30 amarildo kernel: grsec: denied RWX mmap of /usr/lib32/mesa/libGL.so.1.2.0 by /home/amarildo/.local/share/Steam/steamapps/common/Team Fortress 2/hl2_linux[hl2_linux:1902] uid/euid:1000/1000 gid/egid:100/100, parent /home/amarildo/.local/share/Steam/steamapps/common/Team Fortress 2/hl2.sh[hl2.sh:1899] uid/euid:1000/1000 gid/egid:100/100

Please fix this.

Shall the workaround for llvm.12833 be removed?

I notice a workaround for llvm.12833:
https://github.com/ValveSoftware/steamos_mesa/blob/4d8013e2b0914bfb0472778ebf15e27faa0d39fb/src/gallium/auxiliary/gallivm/lp_bld_misc.cpp

  /*
  * Workaround http://llvm.org/bugs/show_bug.cgi?id=12833
  */
 StringRef MArch = "";
 StringRef MCPU = "";
 Triple TT(unwrap(M)->getTargetTriple());
 JIT = builder.create(builder.selectTarget(TT, MArch, MCPU, MAttrs));

This compiler bug is already fixed: https://bugs.llvm.org/show_bug.cgi?id=12833
Shall this workaround be removed?
