* sysdeps/unix/sysv/linux/i386/smp.h: New file. Old Linux-specific
file. Don't use sysctl.
* sysdeps/unix/sysv/linux/smp.h: Always assume SMP. Archs can
overwrite the file if this is likely not true.
2006-07-31 Daniel Jacobowitz <dan@codesourcery.com>
* allocatestack.c (__reclaim_stacks): Reset the PID on cached stacks.
