Linus Torvalds 410feb75de arm64 updates for 4.18: ... - Spectre v4 mitigation (Speculative Store Bypass Disable) support for arm64 using SMC firmware call to set a hardware chicken bit - ACPI PPTT (Processor Properties Topology Table) parsing support and enable the feature for arm64 - Report signal frame size to user via auxv (AT_MINSIGSTKSZ). The primary motivation is Scalable Vector Extensions which requires more space on the signal frame than the currently defined MINSIGSTKSZ - ARM perf patches: allow building arm-cci as module, demote dev_warn() to dev_dbg() in arm-ccn event_init(), miscellaneous cleanups - cmpwait() WFE optimisation to avoid some spurious wakeups - L1_CACHE_BYTES reverted back to 64 (for performance reasons that have to do with some network allocations) while keeping ARCH_DMA_MINALIGN to 128. cache_line_size() returns the actual hardware Cache Writeback Granule - Turn LSE atomics on by default in Kconfig - Kernel fault reporting tidying - Some #include and miscellaneous cleanups -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAlsaoqsACgkQa9axLQDI XvH+8RAAqRCrEtkNPS7zxHyMK/D2cxSy9EVtlJ1sxhmsONEe5t5MDTWX9byobQ5A PAKMSQBQgUvecqHLOtD7SJWef1il30zgWmc/yPcgNv3OsA1Au7j2g3ht/Drw+N5I Vy0aOUEtw+Jzs7y/CJyl6lufSkkOzszOujt2Nybiz6omztOrwkW9isKnURzQBNj5 gquZI35h604YJ9F0TqS6ZqU7tNcuB9q02FxvVBpLmb83jP4jSEjYACUJwVVxvEAB UXjdD4N130rRXDS5OMRWo5+4SAj+kPYhdVYEvaDx7xTOIRHhXK05GlJbsUAc5E6l xy810fH5Dm0diYpVvYWTA5J+BU1jNOvCys5zKWl7gs2P8YB59PdqY4M2YBPNGb5H PaVgq73TZAsww6ZInbZlK+wZOIxZZIOf//Z+QKn6EPtu3RmzIFWwyttTj01w1E3i LhjcUoGnvxJFcMoCr59ihDwfP9nkCVrNc4REOGaWDk6L/t/bOfaZfDz+OCGbwQdL akCFKZI6q5O/no+YfhtdtNFpCQb/Bo1J88KuotICRXq8z4vO41zIG53bi97W8QeG rCBiX0NxUxYJ3ybus7kZHTmMGieMyEHP28n12QffwvJj4vJBsUXQBrV8hclx0djZ HMt7iPi/0BW6nVV7ngIgN3cdCpaDCEGRsfO4Ch0rFZrC9UbYQnE= =uums -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Catalin Marinas: "Apart from the core arm64 and perf changes, the Spectre v4 mitigation touches the arm KVM code and the ACPI PPTT support touches drivers/ (acpi and cacheinfo).
