Linus Torvalds 71c3a888cb powerpc updates for 5.6
- 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.

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.
