For unknown reason, old commit d27dfd388715 ("Import pre2.0.8")
changed 'ptrdiff_t' from 'int' to 'long'.
GCC expects it as 'int' really, and this leads to the following
warning when building KFENCE:
CC mm/kfence/report.o

<asm-generic/uapi/posix-types.h> defines it as 'int', and
defines 'size_t' and 'ssize_t' exactly as powerpc do, so
remove the powerpc specific definitions and fallback on
generic ones.
