      stmhal/pendsv: Disable interrupts during a thread switch. · ebbaf7ee
      Damien George authored
      We can actually handle interrupts during a thread switch (because we always
      have a valid stack), but only if those interrupts don't access any of the
      thread state (because the state may not correspond to the stack pointer).
      So to be on the safe side we disable interrupts during the very short
      period of the thread state+stack switch.
