Matthias Goergens 5f504b31f4 hugetlb_encode.h: fix undefined behaviour (34 << 26)
commit 710bb68c2e3a24512e2d2bae470960d7488e97b1 upstream.

Left-shifting past the size of your datatype is undefined behaviour in C.
The literal 34 gets the type `int`, and that one is not big enough to be
left shifted by 26 bits.

An `unsigned` is long enough (on any machine that has at least 32 bits for
their ints.)

For uniformity, we mark all the literals as unsigned.  But it's only
really needed for HUGETLB_FLAG_ENCODE_16GB.

Thanks to Randy Dunlap for an initial review and suggestion.
