Yonghong Song ced33f2cfa docs/bpf: Improve documentation of 64-bit immediate instructions ... For 64-bit immediate instruction, 'BPF_IMM | BPF_DW | BPF_LD' and src_reg=[0-6], the current documentation describes the 64-bit immediate is constructed by: imm64 = (next_imm << 32) | imm But actually imm64 is only used when src_reg=0. For all other variants (src_reg != 0), 'imm' and 'next_imm' have separate special encoding requirement and imm64 cannot be easily used to describe instruction semantics. This patch clarifies that 64-bit immediate instructions use two 32-bit immediate values instead of a 64-bit immediate value, so later describing individual 64-bit immediate instructions becomes less confusing.
