ksm: change default values to better fit into mainline kernel
Now that ksm is in mainline it is better to change the default values to better fit to most of the users. This patch change the ksm default values to be: ksm_thread_pages_to_scan = 100 (instead of 200) ksm_thread_sleep_millisecs = 20 (like before) ksm_run = KSM_RUN_STOP (instead of KSM_RUN_MERGE - meaning ksm is disabled by default) ksm_max_kernel_pages = nr_free_buffer_pages / 4 (instead of 2046) The important aspect of this patch is: it disables ksm by default, and sets the number of the kernel_pages that can be allocated to be a reasonable number.
