mark such hot-pluggable cpus as disabled entries, one could use this
parameter "additional_cpus=x" to represent those cpus in the cpu_possible_map.
-s390 uses the number of cpus it detects at IPL time to also the number of bits
-in cpu_possible_map. If it is desired to add additional cpus at a later time
-the number should be specified using this option or the possible_cpus option.
-
possible_cpus=n [s390 only] use this to set hotpluggable cpus.
This option sets possible_cpus bits in
cpu_possible_map. Thus keeping the numbers of bits set
constant even if the machine gets rebooted.
- This option overrides additional_cpus.

===============
Quota subsystem allows system administrator to set limits on used space and
-number of used inodes (inode is a filesystem structure which is associated
-with each file or directory) for users and/or groups. For both used space and
-number of used inodes there are actually two limits. The first one is called
-softlimit and the second one hardlimit. An user can never exceed a hardlimit
-for any resource. User is allowed to exceed softlimit but only for limited
-period of time. This period is called "grace period" or "grace time". When
-grace time is over, user is not able to allocate more space/inodes until he
-frees enough of them to get below softlimit.

+of used inodes there are actually two limits. The first one is called softlimit
+and the second one hardlimit. An user can never exceed a hardlimit for any

Quota limits (and amount of grace time) are set independently for each
filesystem.
QUOTA_NL_BSOFTLONGWARN - space (block) softlimit is exceeded
longer than given grace period.
QUOTA_NL_BSOFTWARN - space (block) softlimit
+ - four warnings are also defined for the event when user stops
+ exceeding some limit:
+ QUOTA_NL_IHARDBELOW - inode hardlimit
+ QUOTA_NL_ISOFTBELOW - inode softlimit
+ QUOTA_NL_BHARDBELOW - space (block) hardlimit
+ QUOTA_NL_BSOFTBELOW - space (block) softlimit
QUOTA_NL_A_DEV_MAJOR (u32)
- major number of a device with the affected filesystem
QUOTA_NL_A_DEV_MINOR (u32)
