[PATCH 22/31] perf tools: 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 accessing kernel data. HAVE_BPF_PROLOGUE and CONFIG_BPF_PROLOGUE is added as flags for this feature. PERF_HAVE_ARCH_REGS_QUERY_REGISTER_OFFSET indicates an architecture supports converting name

[PATCH 23/31] perf tools: Introduce regs_query_register_offset() for x86

regs_query_register_offset() is a helper function which converts register name like "%rax" to offset of a register in 'struct pt_regs', which is required by BPF prologue generator. Since the function is identical, try to reuse the code in arch/x86/kernel/ptrace.c. Comment inside dwarf-regs.c list

Possible deadlock related to CPU hotplug and kernfs

Hi Rafael and Tejun, When running CPU hotplug tests, it triggers an lockdep warning as follow. The two possible deadlock paths are: 1) echo x > /sys/devices/system/cpu/cpux/online ->kernfs_fop_write() ->kernfs_get_active() 1.a) ->rwsem_acquire_read(&kn->dep_map, 0, 1, _RET_IP_);
