    powerpc/tm: Avoid SLB faults in treclaim/trecheckpoint when RI=0
    
    Currently we have 2 segments that are bolted for the kernel linear
    mapping (ie 0xc000... addresses). This is 0 to 1TB and also the kernel
    stacks. Anything accessed outside of these regions may need to be
    faulted in. (In practice machines with TM always have 1T segments)
    
    If a machine has < 2TB of memory we never fault on the kernel linear
    mapping as these two segments cover all physical memory. If a machine
    has > 2TB of memory, there may be structures outside of these two
    segments that need to be faulted in. This faulting can occur when
    running as a guest as the hypervisor may remove any SLB that's not
    bolted.
    
    When we treclaim and trecheckpoint we have a window where we need to
    run with the userspace GPRs. This means that we no longer have a valid
    stack pointer in r1. For this window we therefore clear MSR RI to
    indicate that any exceptions taken at this point won't be able to be
    handled. This means that we can't take segment misses in this RI=0
    window.
    
    In this RI=0 region, we currently access the thread_struct for the
    process being context switched to or from. This thread_struct access
    may cause a segment fault since it's not guaranteed to be covered by
    the two bolted segment entries described above.
    
    We've seen this with a crash when running as a guest with > 2TB of
    memory on PowerVM:

    This fixes this by copying the required data from the thread_struct to
    the stack before we clear MSR RI. Then once we clear RI, we only access
    the stack, guaranteeing there's no segment miss.
    
    We also tighten the region over which we set RI=0 on the treclaim()
    path. This may have a slight performance impact since we're adding an
    mtmsr instruction.
