Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas: - ZONE_DMA32 initialisation fix when memblocks fall entirely within the first GB (used by ZONE_DMA in 5.5 for Raspberry Pi 4). - Couple of ftrace fixes following the FTRACE_WITH_REGS patchset. - access_ok() fix for the Tagged Address ABI when called from from a kernel thread (asynchronous I/O): the kthread does not have the TIF flags of the mm owner, so untag the user address unconditionally. - KVM compute_layout() called before the alternatives code patching. - Minor clean-ups. * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: entry: refine comment of stack overflow check arm64: ftrace: fix ifdeffery arm64: KVM: Invoke compute_layout() before alternatives are applied arm64: Validate tagged addresses in access_ok() called from kernel threads arm64: mm: Fix column alignment for UXN in kernel_page_tables arm64: insn: consistently handle exit text arm64: mm: Fix initialisation of DMA zones on non-NUMA systems
