🥳It would be nice to get this in. Recently I learned that Brandon Bergren at FreeBSD used a local patch to fix the powerpc64 size regression caused by lld:

    // We need 64K pages (at least under glibc/Linux, the loader won't
    // set different permissions on a finer granularity than that).
  -  defaultMaxPageSize = 65536;
  + defaultMaxPageSize = 4096;

(It works for them because they use 4k pagesize, but a general fix (this patch) will be preferable.) D64906 <https://reviews.llvm.org/D64906> is also a prerequisite for aarch64 support, which many more people may want.
