Linus Torvalds 6c3ac11343 powerpc updates for 5.1
Notable changes:
 
  - Enable THREAD_INFO_IN_TASK to move thread_info off the stack.
 
  - A big series from Christoph reworking our DMA code to use more of the generic
    infrastructure, as he said:
    "This series switches the powerpc port to use the generic swiotlb and
     noncoherent dma ops, and to use more generic code for the coherent direct
     mapping, as well as removing a lot of dead code."
 
  - Increase our vmalloc space to 512T with the Hash MMU on modern CPUs, allowing
    us to support machines with larger amounts of total RAM or distance between
    nodes.
 
  - Two series from Christophe, one to optimise TLB miss handlers on 6xx, and
    another to optimise the way STRICT_KERNEL_RWX is implemented on some 32-bit
    CPUs.
 
  - Support for KCOV coverage instrumentation which means we can run syzkaller
    and discover even more bugs in our code.
 
 And as always many clean-ups, reworks and minor fixes etc.
