Zhen Lei da359f699f kallsyms: Reduce the memory occupied by kallsyms_seqs_of_names[]
[ Upstream commit 19bd8981dc2ee35fdc81ab1b0104b607c917d470 ]

kallsyms_seqs_of_names[] records the symbol index sorted by address, the
maximum value in kallsyms_seqs_of_names[] is the number of symbols. And
2^24 = 16777216, which means that three bytes are enough to store the
index. This can help us save (1 * kallsyms_num_syms) bytes of memory.
