Modified files:
sys/kern kern_sysctl.c
Log:
Touch all the pages wired by sysctl_wire_old_buffer() to avoid PTE
modified bit emulation traps on Alpha while holding locks in the
sysctl handler.
A better solution would be to pass a hint to the Alpha pmap code to
tell mark these pages as modified when they as they are being wired,
but that appears to be more difficult to implement.
