Wang Nan 1c0ed63239 perf bpf: Add BPF_PROLOGUE config options for further patches ... If both LIBBPF and DWARF are detected, it is possible to create prologue for eBPF programs to help them access kernel data. HAVE_BPF_PROLOGUE and CONFIG_BPF_PROLOGUE are added as flags for this feature. PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET is introduced in commit 63ab024a5b ("perf tools: regs_query_register_offset() infrastructure"), which indicates that an architecture supports converting name of a register to its offset in 'struct pt_regs'. Without this support, BPF_PROLOGUE should be turned off.
