I ran into a 4.9 build warning in randconfig testing, starting with the KAISER patches:
arch/x86/kernel/ldt.c: In function 'alloc_ldt_struct': arch/x86/include/asm/pgtable_types.h:208:24: error: large integer implicitly truncated to unsigned type [-Werror=overflow] #define __PAGE_KERNEL (__PAGE_KERNEL_EXEC | _PAGE_NX) ^ arch/x86/kernel/ldt.c:81:6: note: in expansion of macro '__PAGE_KERNEL' __PAGE_KERNEL); ^~~~~~~~~~~~~
I originally ran into this last year when the patches were part of linux-next, and tried to work around it by using the proper 'pteval_t' types consistently, but that caused additional problems.
This takes a much simpler approach, and makes the argument type of the dummy helper always 64-bit, which is wide enough for any page table layout and won't hurt since this call is just an empty stub anyway.
