Bui Quang Minh 7e3a6b8205 bpf: Check for integer overflow when using roundup_pow_of_two() ... [ Upstream commit 6183f4d3a0a2ad230511987c6c362ca43ec0055f ] On 32-bit architecture, roundup_pow_of_two() can return 0 when the argument has upper most bit set due to resulting 1UL << 32. Add a check for this case.
