Merge tag 'powerpc-4.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux
Pull powerpc updates from Michael Ellerman: - disable the 32-bit vdso when building LE, so we can build with a 64-bit only toolchain. - EEH fixes from Gavin & Richard. - enable the sys_kcmp syscall from Laurent. - sysfs control for fastsleep workaround from Shreyas. - expose OPAL events as an irq chip by Alistair. - MSI ops moved to pci_controller_ops by Daniel. - fix for kernel to userspace backtraces for perf from Anton. - merge pseries and pseries_le defconfigs from Cyril. - CXL in-kernel API from Mikey. - OPAL prd driver from Jeremy. - fix for DSCR handling & tests from Anshuman. - Powernv flash mtd driver from Cyril. - dynamic DMA Window support on powernv from Alexey. - LLVM clang fixes & workarounds from Anton. - reworked version of the patch to abort syscalls when transactional. - fix the swap encoding to support 4TB, from Aneesh. - various fixes as usual. - Freescale updates from Scott: Highlights include more 8xx optimizations, an e6500 hugetlb optimization, QMan device tree nodes, t1024/t1023 support, and various fixes and cleanup. * tag 'powerpc-4.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux: (180 commits) cxl: Fix typo in debug print cxl: Add CXL_KERNEL_API config option powerpc/powernv: Fix wrong IOMMU table in pnv_ioda_setup_bus_dma() powerpc/mm: Change the swap encoding in pte. powerpc/mm: PTE_RPN_MAX is not used, remove the same powerpc/tm: Abort syscalls in active transactions powerpc/iommu/ioda2: Enable compile with IOV=on and IOMMU_API=off powerpc/include: Add opal-prd to installed uapi headers powerpc/powernv: fix construction of opal PRD messages powerpc/powernv: Increase opal-irqchip initcall priority powerpc: Make doorbell check preemption safe powerpc/powernv: pnv_init_idle_states() should only run on powernv macintosh/nvram: Remove as unused powerpc: Don't use gcc specific options on clang powerpc: Don't use -mno-strict-align on clang powerpc: Only use -mtraceback=no, -mno-string and -msoft-float if toolchain supports it powerpc: Only use -mabi=altivec if toolchain supports it powerpc: Fix duplicate const clang warning in user access code vfio: powerpc/spapr: Support Dynamic DMA windows vfio: powerpc/spapr: Register memory and define IOMMU v2 ...
