This can fix ARM_MODULE_PLTS with KASAN and provide first step to support CONFIG_VMAP_STACK in ARM. Patch base on v5.16 Test on 1. Qemu with memory 2G and vmalloc=500M for 3G/1G mapping. 2. Qemu with memory 2G and vmalloc=500M for 3G/1G mapping + LPAE. 3. Qemu with memory 2G and vmalloc=500M for 2G/2G mapping. v2: rebase on 5.17-rc3 Lecopzer Chen (2): arm: kasan: support CONFIG_KASAN_VMALLOC arm: kconfig: fix MODULE_PLTS for KASAN with KASAN_VMALLOC arch/arm/Kconfig | 2 ++ arch/arm/mm/kasan_init.c | 6 +++++- 2 files changed, 7 insertions(+), 1 deletion(-) -- 2.25.1
