sys/kern init_main.c kern_thread.c
Log:
Align 'struct thread' on 16 byte boundaries so that the lower 4 bits are
always 0. Previously we aligned threads on a minimum of 8-byte boundaries.
Note: This changes the uma zone to no longer cache align threads. We
really want the uma zone to do align threads to MAX(16, cache line size)
but there currently isn't a good way to express that to uma.
We can workaround it using a function like:
int uma_get_align(void)
(which would be the counter part of uma_set_align).
Its implementations is trivial.
