[PATCH] u_int32_t causes cross-compile problems

From: Pratik Solanki <pratik.solanki@timesys.com>

I came across this C standards issue while cross-compiling the Linux kernel
with gcc on Solaris.  The file gen_crc32table.c uses the non-standard type
u_int32_t.  It's possible that the host machine's sys/types.h does not
define u_int32_t.  The attached patch replaces u_int32_t with the POSIX
standard uint32_t and includes POSIX inttypes.h instead of sys/types.h.
