thus introducing undefined behavior.  Stop it from doing so.

    • runtime: If no split stacks, allocate stacks using mmap on 64-bit systems. · 2b193803 
          
    When not using split stacks, libgo allocate large stacks for each
    goroutine.  On a 64-bit system, libgo allocates a maximum of 128G for
    the Go heap, and allocates 4M for each stack.  When the stacks are
    allocated from the Go heap, the result is that a program can only create
    32K goroutines, which is not enough for an active Go server.  This patch
    changes libgo to allocate the stacks using mmap directly, rather than
    allocating them out of the Go heap.  This change is only done for 64-bit
    systems when not using split stacks.  When using split stacks, the
    stacks are allocated using mmap directly anyhow.  On a 32-bit system,
    there is no maximum size for the Go heap, or, rather, the maximum size
    is the available address space anyhow.

    • rs6000: Another PIC LRA fix · f44c1eb7 
      This one for TARGET_TOC && TARGET_MINIMAL_TOC.  Without it, r30 is not
saved in the prologue for functions that do not use r30, but the register
is set later in the prologue anyhow.  This made all java tests fail.
