Declare __page_shift and __page_size with C linkage
__page_shift and __page_size are defined in asm/page.h with
C linkage - their implementation needs to use the same linkage.
The different linkage types cause a compiler error with clang.
Fixing them seems to be a good idea regardless of the compiler.
