s390 uses the number of cpus it detects at IPL time to also the number of bits

the number should be specified using this option or the possible_cpus option.

What: mount/umount uevents
When: February 2007
Why: These events are not correct, and do not properly let userspace know
when a file system has been mounted or unmounted. Userspace should
poll the /proc/mounts file instead to detect this properly.

tmpfs has a mount option to set the NUMA memory allocation policy for
all files in that instance:
mpol=interleave prefers to allocate memory from each node in turn
mpol=default prefers to allocate memory from the local node
mpol=bind prefers to allocate from mpol_nodelist
mpol=preferred prefers to allocate from first node in mpol_nodelist
all files in that instance (if CONFIG_NUMA is enabled) - which can be
adjusted on the fly via 'mount -o remount ...'
The following mount option is used in conjunction with mpol=interleave,
mpol=bind or mpol=preferred:
mpol_nodelist: nodelist suitable for parsing with nodelist_parse.
mpol=default prefers to allocate memory from the local node
mpol=prefer:Node prefers to allocate memory from the given Node
mpol=bind:NodeList allocates memory only from nodes in NodeList
mpol=interleave prefers to allocate from each node in turn
mpol=interleave:NodeList allocates from each node of NodeList in turn
NodeList format is a comma-separated list of decimal numbers and ranges,
a range being two hyphen-separated decimal numbers, the smallest and
largest node numbers in the range. For example, mpol=bind:0-3,5,7,9-15
