Chris Metcalf 3e2e0d2c22 tile: comment assumption about __insn_mtspr for <asm/irqflags.h> ... The arch_local_irq_save(), etc., routines are required to function as compiler barriers. They do, but it's subtle and requires knowing that the gcc builtin __insn_mtspr() is marked as a memory clobber. Provide a comment explaining the assumption.
