commit 6b80ec957c64fc3ca7a32adc504fefd226d7dad0

types: replace remaining uses of s64
... and move the type itself to linux-compat.h. An exception being
arch/arm/arm64/cpufeature.c and arch/arm/include/asm/arm64/cpufeature.h,
which are to use linux-compat.h instead (the former by including the
latter).
While doing so
- correct the type of union uu's uq field in lib/divmod.c,
- switch a few adjacent types as well, for (a little bit of)
consistency.
