Transaction Check Error:
  installing package kernel-2.6.32-131.2.1.el6.x86_64 needs 8MB on the /boot filesystem

Error Summary
-------------
Disk Requirements:
  At least 8MB more space needed on the /boot filesystem.

How do I fix this error and install RHEL kernel without increasing /boot size or reinstalling the operating system?
