A 32 bit cross compilation of x86_64-linux-user raises this error:
CC x86_64-linux-user/exec.o
cc1: warnings being treated as errors
exec.c: In function ‘page_init’:
exec.c:350: error: large integer implicitly truncated to unsigned type
L1_MAP_ADDR_SPACE_BITS == 47, HOST_LONG_BITS == 32,
so the shift operation indeed is problematic.
Limit endaddr to ULONG_MAX in this case.
