Merge tag 'powerpc-6.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman: - Extend KCSAN support to 32-bit and BookE. Add some KCSAN annotations - Make ELFv2 ABI the default for 64-bit big-endian kernel builds, and use the -mprofile-kernel option (kernel specific ftrace ABI) for big endian ELFv2 kernels - Add initial Dynamic Execution Control Register (DEXCR) support, and allow the ROP protection instructions to be used on Power 10 - Various other small features and fixes Thanks to Aditya Gupta, Aneesh Kumar K.V, Benjamin Gray, Brian King, Christophe Leroy, Colin Ian King, Dmitry Torokhov, Gaurav Batra, Jean Delvare, Joel Stanley, Marco Elver, Masahiro Yamada, Nageswara R Sastry, Nathan Chancellor, Naveen N Rao, Nayna Jain, Nicholas Piggin, Paul Gortmaker, Randy Dunlap, Rob Herring, Rohan McLure, Russell Currey, Sachin Sant, Timothy Pearson, Tom Rix, and Uwe Kleine-König. * tag 'powerpc-6.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: (76 commits) powerpc: remove checks for binutils older than 2.25 powerpc: Fail build if using recordmcount with binutils v2.37 powerpc/iommu: TCEs are incorrectly manipulated with DLPAR add/remove of memory powerpc/iommu: Only build sPAPR access functions on pSeries powerpc: powernv: Annotate data races in opal events powerpc: Mark writes registering ipi to host cpu through kvm and polling powerpc: Annotate accesses to ipi message flags powerpc: powernv: Fix KCSAN datarace warnings on idle_state contention powerpc: Mark [h]ssr_valid accesses in check_return_regs_valid powerpc: qspinlock: Enforce qnode writes prior to publishing to queue powerpc: qspinlock: Mark accesses to qnode lock checks powerpc/powernv/pci: Remove last IODA1 defines powerpc/powernv/pci: Remove MVE code powerpc/powernv/pci: Remove ioda1 support powerpc: 52xx: Make immr_id DT match tables static powerpc: mpc512x: Remove open coded "ranges" parsing powerpc: fsl_soc: Use of_range_to_resource() for "ranges" parsing powerpc: fsl: Use of_property_read_reg() to parse "reg" powerpc: fsl_rio: Use of_range_to_resource() for "ranges" parsing macintosh: Use of_property_read_reg() to parse "reg" ...
