Merge tag 'powerpc-5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
"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.
