It started with this commit:

  2020. jdolecek src/sys/conf/ 1.274

  enable gcc stack usage limit for kernel functions, set to 3.5 KiB for now
  as that seems to be enough to accomodate the current biggest stack usages

  there are about six functions which use over 3KiB local stack, and
  about a dozen between 2-3 KiB, so pushing this further needs more work
  if desired

  compile tested on amd64, i386, sparc64, sparc, powerpc (evbppc - BookE),
  m68k (mac68k)
