This avoids us executing an mfc0 c0_count instruction on processors which don't have but also on certain R4000 and R4400 versions where reading from the count register just in the very moment when its value equals c0_compare will result in the timer interrupt getting lost. There is still a number of users of get_cycles remaining outside the arch code: crypto/tcrypt.c: start = get_cycles(); crypto/tcrypt.c: end = get_cycles(); crypto/tcrypt.c: start = get_cycles(); crypto/tcrypt.c: end = get_cycles(); crypto/tcrypt.c: start = get_cycles(); crypto/tcrypt.c: end = get_cycles(); drivers/char/hangcheck-timer.c: return get_cycles(); drivers/char/hangcheck-timer.c: printk("Hangcheck: Using get_cycles().\n"); drivers/char/random.c: sample.cycles = get_cycles(); drivers/input/joystick/analog.c:#define GET_TIME(x) do { x = get_cycles(); } include/linux/arcdevice.h: _x = get_cycles(); \ include/linux/arcdevice.h: _y = get_cycles(); \ mm/slub.c: if (!s->defrag_ratio || get_cycles() % 1024 > s->defrag_ratio) mm/slub.c: p += 64 + (get_cycles() & 0xff) * sizeof(void *); Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
