Merge tag 'powerpc-4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc fixes from Michael Ellerman: "Some things that I missed due to travel, or that came in late. Two fixes also going to stable: - A revert of a buggy change to the 8xx TLB miss handlers. - Our flushing of SPE (Signal Processing Engine) registers on fork was broken. Other changes: - A change to the KVM decrementer emulation to use proper APIs. - Some cleanups to the way we do code patching in the 8xx code. - Expose the maximum possible memory for the system in /proc/powerpc/lparcfg. - Merge some updates from Scott: "a couple device tree updates, and a fix for a missing prototype warning" A few other minor fixes and a handful of fixes for our selftests. Thanks to: Aravinda Prasad, Breno Leitao, Camelia Groza, Christophe Leroy, Felipe Rechia, Joel Stanley, Naveen N. Rao, Paul Mackerras, Scott Wood, Tyrel Datwyler" * tag 'powerpc-4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux: (21 commits) selftests/powerpc: Fix compilation issue due to asm label selftests/powerpc/cache_shape: Fix out-of-tree build selftests/powerpc/switch_endian: Fix out-of-tree build selftests/powerpc/pmu: Link ebb tests with -no-pie selftests/powerpc/signal: Fix out-of-tree build selftests/powerpc/ptrace: Fix out-of-tree build powerpc/xmon: Relax frame size for clang selftests: powerpc: Fix warning for security subdir selftests/powerpc: Relax L1d miss targets for rfi_flush test powerpc/process: Fix flush_all_to_thread for SPE powerpc/pseries: add missing cpumask.h include file selftests/powerpc: Fix ptrace tm failure KVM: PPC: Use exported tb_to_ns() function in decrementer emulation powerpc/pseries: Export maximum memory value powerpc/8xx: Use patch_site for perf counters setup powerpc/8xx: Use patch_site for memory setup patching powerpc/code-patching: Add a helper to get the address of a patch_site Revert "powerpc/8xx: Use L1 entry APG to handle _PAGE_ACCESSED for CONFIG_SWAP" powerpc/8xx: add missing header in 8xx_mmu.c powerpc/8xx: Add DT node for using the SEC engine of the MPC885 ...
