This series applies on top of Aaron's series "module: core code clean up" v6, plus the 4 fixups I just sent: - Fixup for 54f2273e5fef ("module: Move kallsyms support into a separate file") - Fixup for e5973a14d187 ("module: Move strict rwx support to a separate file") - Fixup for 1df95c1b9fb2 ("module: Move latched RB-tree support to a separate file") - Fixup for 87b31159f78a ("module: Move all into module/") This series 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. Without this change module data remains executable regardless of CONFIG_STRICT_MODULES_RWX. 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. Changes in v4: - Rebased on top of Aaron's series "module: core code clean up" v6 Changes in v3: - Fixed the tree for data_layout at one place (Thanks Miroslav) - Moved removal of module_addr_min/module_addr_max macro out of patch 1 in a new patch at the end of the series to reduce churn. Changes in v2: - Dropped first two patches which are not necessary. They may be added back later as a follow-up series. - Fixed the printks in GDB Christophe Leroy (6): module: Always have struct mod_tree_root module: Prepare for handling several RB trees module: Introduce data_layout module: Add CONFIG_ARCH_WANTS_MODULES_DATA_IN_VMALLOC module: Remove module_addr_min and module_addr_max powerpc: Select ARCH_WANTS_MODULES_DATA_IN_VMALLOC on book3s/32 and 8xx arch/Kconfig | 6 +++ arch/powerpc/Kconfig | 1 + include/linux/module.h | 8 +++ kernel/debug/kdb/kdb_main.c | 10 +++- kernel/module/internal.h | 13 +++-- kernel/module/kallsyms.c | 18 +++---- kernel/module/main.c | 103 +++++++++++++++++++++++++++--------- kernel/module/procfs.c | 8 ++- kernel/module/strict_rwx.c | 10 ++-- kernel/module/tree_lookup.c | 28 ++++++---- 10 files changed, 149 insertions(+), 56 deletions(-) -- 2.34.1
