Kernel parameter "memmap="

[David kiarie]

Am trying to reserve memory using the kernel parameter
"memmap=66M$0x3b000000" on Qemu but it happens that the kernel does not
boot.

I get a panic with the error :

kernel not syncing: Out of memory and not killable processes

Is there something I am missing ?Should I use some options when building
the kernel to allow this command line option ?

Cheers,
Asla
