Add perf_event_mips_regs/perf_reg_value/perf_reg_validate to support features HAVE_PERF_REGS/HAVE_PERF_USER_STACK_DUMP in kernel. [ayan@wavecomp.com: Repick this patch for unwinding userstack backtrace by perf and libunwind on MIPS based CPU.] [ralf@linux-mips.org: Add perf_get_regs_user() which is required after 'commit88a7c26af8("perf: Move task_pt_regs sampling into arch code")'.] [yangtiezhu@loongson.cn: 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 <david.daney@cavium.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Archer Yan <ayan@wavecomp.com> Signed-off-by: Tiezhu Yang <yangtiezhu@loongson.cn> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
