Adds missing #include <linux/mm.h> drivers/tee/optee/smc_abi.c to fix compile errors like: drivers/tee/optee/smc_abi.c:405:15: error: implicit declaration of function 'page_to_section' [-Werror,-Wimplicit-function-declaration] optee_page = page_to_phys(*pages) + ^ arch/arm/include/asm/memory.h:148:43: note: expanded from macro 'page_to_phys' ^ include/asm-generic/memory_model.h:52:21: note: expanded from macro 'page_to_pfn' ^ include/asm-generic/memory_model.h:35:14: note: expanded from macro '__page_to_pfn' int __sec = page_to_section(__pg); \ ^ drivers/tee/optee/smc_abi.c:405:15: note: did you mean '__nr_to_section'? arch/arm/include/asm/memory.h:148:43: note: expanded from macro 'page_to_phys' ^ include/asm-generic/memory_model.h:52:21: note: expanded from macro 'page_to_pfn' ^ include/asm-generic/memory_model.h:35:14: note: expanded from macro '__page_to_pfn' int __sec = page_to_section(__pg); \ ^ include/linux/mmzone.h:1365:35: note: '__nr_to_section' declared here static inline struct mem_section *__nr_to_section(unsigned long nr)

I wasn't able to reproduce the error above. It obviously involves CONFIG_SPARSEMEM=y, but something more seems to be needed to trigger the error. Nonetheless, including <linux/mm.h> should fix the error.

Thanks, Jens
