From: George Guo <[email protected]> luo_session.c calls virt_to_phys() and phys_to_virt(). On LoongArch with CONFIG_KFENCE=y, these macros (in arch/loongarch/include/asm/io.h) expand to offset_in_page() and page_address(), both declared in <linux/mm.h>.
Since luo_session.c only includes <linux/io.h>, the translation unit fails to build with CONFIG_KFENCE=y: asm/io.h: error: implicit declaration of function 'offset_in_page' asm/io.h: error: implicit declaration of function 'page_address' Add the missing include to fix these build errors.
