New Revision: 338201
URL: https://svnweb.freebsd.org/changeset/base/338201

Log:
  Increase the size of the heap size available on sparc64 during
  operation of "loader".  The dramatic increase in size of
  SPA_MAXBLOCKSIZE in r304321 causes the heap space to be exhausted,
  so malloc() fails, ultimately leading to a memcpy() with a
  destination of 0x0.
