Hi Linus,

Please pull powerpc updates for 5.4.

This is a bit late, partly due to me travelling, and partly due to a power
outage knocking out some of my test systems *while* I was travelling.

A few conflicts this time unfortunately. The key one is the silent conflict with
the dma-mapping tree. You need to delete our copy of atomic_pool_init() and the
postcore_initcall() that calls it in arch/powerpc/mm/dma-noncoherent.c

In arch/Kconfig, ARCH_HAS_MEM_ENCRYPT and RELR both went in via separate paths,
we just want to take both sides of the conflict.

In book3s_64_vio.c and book3s_64_vio_hv.c Paul and I both merged the same fix,
and then I merged another patch on top, leading to a conflict. The resolution is
to take the "goto invalidate_exit" cases.

I've pushed the result of my merge to the v5.4-merge branch if there's any
doubt.

There's also a few out of area changes. The extable changes are due to
49ec9177b8ec ("extable: Add function to search only kernel exception table").

The move of ARCH_HAS_MEM_ENCRYPT into arch/Kconfig & related cleanups are
responsible for all the changes under arch, as well as fs/proc/vmcore.c,
crash_dump.h, mem_encrypt.h, and kernel/dma/(mapping|swiotlb).c.

And the kernel/trace/fgraph.c change was acked by Steve.

cheers

powerpc/mm/mce: Keep irqs disabled during lockless page table walk (2019-09-19 21:24:59 +1000)

- ------------------------------------------------------------------
powerpc updates for 5.4

- Initial support for running on a system with an Ultravisor, which is software
that runs below the hypervisor and protects guests against some attacks by
the hypervisor.

- Support for building the kernel to run as a "Secure Virtual Machine", ie. as
a guest capable of running on a system with an Ultravisor.

- Some changes to our DMA code on bare metal, to allow devices with medium
sized DMA masks (> 32 && < 59 bits) to use more than 2GB of DMA space.

- Support for firmware assisted crash dumps on bare metal (powernv).

- Two series fixing bugs in and refactoring our PCI EEH code.

- A large series refactoring our exception entry code to use gas macros, both
to make it more readable and also enable some future optimisations.

As well as many cleanups and other minor features & fixups.
