module: Move all into module/ No functional changes. This patch moves all module related code into a separate directory, modifies each file name and creates a new Makefile. Note: this effort is in preparation to refactor core module code.

module: Move module_enable_x() and frob_text() in strict_rwx.c Move module_enable_x() together with module_enable_nx() and module_enable_ro(). Those three functions are going together, they are all used to set up the correct page flags on the different sections. As module_enable_x() is used independently of CONFIG_STRICT_MODULE_RWX, build strict_rwx.c all the time and use IS_ENABLED(CONFIG_STRICT_MODULE_RWX) when relevant.

module: Move livepatch support to a separate file No functional change. This patch migrates livepatch support (i.e. used during module add/or load and remove/or deletion) from core module code into kernel/module/livepatch.c. At the moment it contains code to persist Elf information about a given livepatch module, only. The new file was added to MAINTAINERS.

module: Move kdb module related code out of main kdb code No functional change. This patch migrates the kdb 'lsmod' command support out of main kdb code into its own file under kernel/module. In addition to the above, a minor style warning i.e. missing a blank line after declarations, was resolved too. The new file was added to MAINTAINERS. Finally we remove linux/module.h as it is entirely redundant.

module: Introduce module unload taint tracking Currently, only the initial module that tainted the kernel is recorded e.g. when an out-of-tree module is loaded. The purpose of this patch is to allow the kernel to maintain a record of each unloaded module that taints the kernel. So, in addition to displaying a list of linked modules (see print_modules()) e.g. in the event of a detected bad page, unloaded modules that carried a taint/or taints are displayed too. A tainted module unload count is maintained. The number of tracked modules is not fixed. This feature is disabled by default.
