boot

I would like to dynamically allocate memory from the machine_init function in my arm linux kernel. Calling kalloc can result in a complete failure of the system to boot.

My debugging tools are very limited so I can't give much more information regarding the failure.

Simply put, is it legal to call kalloc from a machine_init function in arm linux, and, if not, is there an alternative?
