[PATCH v3 01/13] nios2: define virtual address space for modules

From: "Mike Rapoport (IBM)" nios2 uses kmalloc() to implement module_alloc() because CALL26/PCREL26 cannot reach all of vmalloc address space. Define module space as 32MiB below the kernel base and switch nios2 to use vmalloc for module allocations. Suggested-by: Thomas Gleixner

[PATCH v3 00/13] mm: jit/text allocator

[PATCH v2 12/12] kprobes: remove dependcy on CONFIG_MODULES

From: "Mike Rapoport (IBM)" kprobes depended on CONFIG_MODULES because it has to allocate memory for code. Since code allocations are now implemented with execmem, kprobes can be enabled in non-modular kernels. Add #ifdef CONFIG_MODULE guards for the code dealing with kprobes insi

[PATCH v2 11/12] x86/ftrace: enable dynamic ftrace without CONFIG_MODULES

From: "Mike Rapoport (IBM)" Dynamic ftrace must allocate memory for code and this was impossible without CONFIG_MODULES. With execmem separated from the modules code, execmem_text_alloc() is available regardless of CONFIG_MODULES. Remove dependency of dynamic ftrace on CONFIG_MODULE

[PATCH v2 10/12] arch: make execmem setup available regardless of CONFIG_MODULES

From: "Mike Rapoport (IBM)" execmem does not depend on modules, on the contrary modules use execmem. To make execmem available when CONFIG_MODULES=n, for instance for kprobes, split execmem_params initialization out from arch/kernel/module.c and compile it when CONFIG_EXECMEM=y Sig

[PATCH v2 09/12] powerpc: extend execmem_params for kprobes allocations

From: "Mike Rapoport (IBM)" powerpc overrides kprobes::alloc_insn_page() to remove writable permissions when STRICT_MODULE_RWX is on. Add definition of jit area to execmem_params to allow using the generic kprobes::alloc_insn_page() with the desired permissions. As powerpc uses

[PATCH v2 08/12] riscv: extend execmem_params for kprobes allocations

From: "Mike Rapoport (IBM)" RISC-V overrides kprobes::alloc_insn_range() to use the entire vmalloc area rather than limit the allocations to the modules area. Slightly reorder execmem_params initialization to support both 32 and 64 bit variantsi and add definition of jit area to exec

[PATCH v2 07/12] arm64, execmem: extend execmem_params for generated code definitions

From: "Mike Rapoport (IBM)" The memory allocations for kprobes on arm64 can be placed anywhere in vmalloc address space and currently this is implemented with an override of alloc_insn_page() in arm64. Extend execmem_params with a range for generated code allocations and make kprobe

[PATCH v2 06/12] mm/execmem: introduce execmem_data_alloc()

From: "Mike Rapoport (IBM)" Data related to code allocations, such as module data section, need to comply with architecture constraints for its placement and its allocation right now was done using execmem_text_alloc(). Create a dedicated API for allocating data related to code alloc

[PATCH v2 05/12] modules, execmem: drop module_alloc
