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 pa= ths, 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 f= ix, and then I merged another patch on top, leading to a conflict. The resoluti= on 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 The following changes since commit 609488bc979f99f805f34e9a32c1e3b71179d10b: Linux 5.3-rc2 (2019-07-28 12:47:02 -0700) are available in the git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux.git tags/po= werpc-5.4-1 for you to fetch changes up to d9101bfa6adc831bda8836c4d774820553c14942: 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 sof= tware 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, b= oth to make it more readable and also enable some future optimisations. As well as many cleanups and other minor features & fixups.
