svn commit: r360635 - in head/contrib/jemalloc: . include/jemalloc

New Revision: 360635
URL: https://svnweb.freebsd.org/changeset/base/360635

Log:
  Set LG_VADDR to 48 on RISC-V.
  
  The Sv48 PTE format is the largest currently defined address space for
  RISC-V. It makes no sense to define a larger size and doing so (at
  least for 64-bits) forces rtrees down a slow path.
