David Wang f9ed1f7c2e genirq/proc: Use seq_put_decimal_ull_width() for decimal values ... seq_printf() is more expensive than seq_put_decimal_ull_width() due to the format string parsing costs. Profiling on a x86 8-core system indicates seq_printf() takes ~47% samples of show_interrupts(). Replacing it with seq_put_decimal_ull_width() yields almost 30% performance gain.
