Add perf_event_mips_regs/perf_reg_value/perf_reg_validate to support features HAVE_PERF_REGS/HAVE_PERF_USER_STACK_DUMP in kernel. [[email protected]: Repick this patch for unwinding userstack backtrace by perf and libunwind on MIPS based CPU.] [[email protected]: Add perf_get_regs_user() which is required after 'commit88a7c26af8("perf: Move task_pt_regs sampling into arch code")'.] [[email protected]: Fix build error about perf_get_regs_user() after commit76a4efa809("perf/arch: Remove perf_sample_data::regs_user_copy"), and also separate the original patches into two parts (MIPS kernel and perf tools) to merge easily.] The original patches: https://lore.kernel.org/patchwork/patch/1126521/ https://lore.kernel.org/patchwork/patch/1126520/ Signed-off-by: David Daney <[email protected]> Signed-off-by: Ralf Baechle <[email protected]> Signed-off-by: Archer Yan <[email protected]> Signed-off-by: Tiezhu Yang <[email protected]> Signed-off-by: Thomas Bogendoerfer <[email protected]>
