Could this comparison preserve unsigned-long semantics? On 32-bit targets,
CONST is an unsigned long, while PTRACE_PEEKDATA returns the same bit pattern
as a negative signed long. TST_EXP_EQ_LI() converts them separately to signed
long long, producing -559038737 and 3735928559, so every successful peek is
reported as TFAIL.

Could this entry be placed in a .gitignore under
testcases/kernel/mem/hugetlb/hugemmap/? New test binaries should be ignored
in their own test directory rather than in a parent .gitignore.

Verdict - Needs revision
