Pull modules updates from Luis Chamberlain: "Finally something fun. Mike Rapoport does some cleanup to allow us to take out module_alloc() out of modules into a new paint shedded execmem_alloc() and execmem_free() so to make emphasis these helpers are actually used outside of modules. It starts with a non-functional changes API rename / placeholders to then allow architectures to define their requirements into a new shiny struct execmem_info with ranges, and requirements for those ranges. Archs now can intitialize this execmem_info as the last part of mm_core_init() if they have to diverge from the norm. Each range is a known type clearly articulated and spelled out in enum execmem_type. Although a lot of this is major cleanup and prep work for future enhancements an immediate clear gain is we get to enable KPROBES without MODULES now. That is ultimately what motiviated to pick this work up again, now with smaller goal as concrete stepping stone" * tag 'modules-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: bpf: remove CONFIG_BPF_JIT dependency on CONFIG_MODULES of kprobes: remove dependency on CONFIG_MODULES powerpc: use CONFIG_EXECMEM instead of CONFIG_MODULES where appropriate x86/ftrace: enable dynamic ftrace without CONFIG_MODULES arch: make execmem setup available regardless of CONFIG_MODULES powerpc: extend execmem_params for kprobes allocations arm64: extend execmem_info for generated code allocations riscv: extend execmem_params for generated code allocations mm/execmem, arch: convert remaining overrides of module_alloc to execmem mm/execmem, arch: convert simple overrides of module_alloc to execmem mm: introduce execmem_alloc() and execmem_free() module: make module_memory_{alloc,free} more self-contained sparc: simplify module_alloc() nios2: define virtual address space for modules mips: module: rename MODULE_START to MODULES_VADDR arm64: module: remove unneeded call to kasan_alloc_module_shadow() kallsyms: replace deprecated strncpy with strscpy module: allow UNUSED_KSYMS_WHITELIST to be relative against objtree.
