Merge tag 'powerpc-5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
"A pretty small batch for us, and apologies for it being a bit late, I
wanted to sneak Christophe's user_access_begin() series in.
Summary:
- Implement user_access_begin() and friends for our platforms that
support controlling kernel access to userspace.
- Enable CONFIG_VMAP_STACK on 32-bit Book3S and 8xx.
- Some tweaks to our pseries IOMMU code to allow SVMs ("secure"
virtual machines) to use the IOMMU.
- Add support for CLOCK_{REALTIME/MONOTONIC}_COARSE to the 32-bit
VDSO, and some other improvements.
- A series to use the PCI hotplug framework to control opencapi
card's so that they can be reset and re-read after flashing a new
FPGA image.
As well as other minor fixes and improvements as usual.
