2022-07-14module: Modify module_flags() to accept show_state argumentAaron Tomlin1-1/+1
No functional change. With this patch a given module's state information (i.e. 'mod->state') can be omitted from the specified buffer. Please note that this is in preparation to include the last unloaded module's taint flag(s), if available.

2022-04-05module: Add CONFIG_ARCH_WANTS_MODULES_DATA_IN_VMALLOCChristophe Leroy1-2/+6
Add CONFIG_ARCH_WANTS_MODULES_DATA_IN_VMALLOC to allow architectures to request having modules data in vmalloc area instead of module area. This is required on powerpc book3s/32 in order to set data non executable, because it is not possible to set executability on page basis, this is done per 256 Mbytes segments. The module area has exec right, vmalloc area has noexec. This can also be useful on other powerpc/32 in order to maximize the chance of code being close enough to kernel core to avoid branch trampolines.

2022-04-05module: Move procfs support into a separate fileAaron Tomlin1-0/+142
No functional change. This patch migrates code that allows one to generate a list of loaded/or linked modules via /proc when procfs support is enabled into kernel/module/procfs.c.
