Best practice is to download N-1 kernel patch from the Service Market Place. It means if the current kernel patch is 176 and the prior kernel patch is 150 and if you are in a lower kernel version (for ex: 124 etc), it is better to upgrade to N-1 kernel patch i.e. to 150 instead of upgrading directly to 176. The reason for this is sometimes upgrading to latest kernel may lead to some issues like performance problems, system startup failure etc. To avoid this, it is suggested to apply N-1 kernel patch.
