Hi Linus,
Please pull powerpc updates for 5.1.
Stephen reported a couple of conflicts with the dma & swiotlb trees due to
Christoph's DMA series, but you haven't merged those trees yet so I'm not seeing
them when I test merge. They were both fairly trivial though so I don't think
they should cause any trouble.
cheers
The following changes since commit 1c7fc5cbc33980acd13d668f1c8f0313d6ae9fd8:

powerpc/32: Clear on-stack exception marker upon exception return (2019-03-04 00:37:23 +1100)
- ------------------------------------------------------------------
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.
