Not at the present. These Limits/Restrictions are not something you can do
on a normal (non-s_context) kernel either.

Override resource limits. Set resource limits.
Override quota limits.
Override reserved space on ext2 filesystem
NOTE: ext2 honors fsuid when checking for resource overrides, so
you can override using fsuid too
Override size restrictions on IPC message queues
Allow more than 64hz interrupts from the real-time clock
Override max number of consoles on console allocation
Override max number of keymaps
Which of the above do you think you need--that is causing you to want to
