      MIPS: perf: Mark pmu interupt IRQF_NO_THREAD · ec756d45
      Yang Wei authored
      In RT kernel, I ran into the following calltrace, so PMU interrupts cannot
      be threaded
      in_atomic(): 1, irqs_disabled(): 1, pid: 0, name: swapper/0
      INFO: lockdep is turned off.
      Call Trace:

      [ralf@linux-mips.org: I don't see why based on this register dump the
      handler should be marked IRQF_NO_THREAD - but the handler is manipulating
      per-CPU resources so we don't want it to be rescheduled to another CPU.]

      arm64: compat: wire up memfd_create and getrandom syscalls for aarch32 · a97a42c4
      Will Deacon authored
      arch/arm/ just grew support for the new memfd_create and getrandom
      syscalls, so add them to our compat layer too.
