The kernel memory allocator divides physically contiguous memory

blocks into "zones", where each zone is a power of two number of

pages. This option selects the largest power of two that the kernel

keeps in the memory allocator. If you need to allocate very large

blocks of physically contiguous memory, then you may need to
|

increase this value.
|

This config option is actually maximum order plus one. For example,
|

a value of 11 means that the largest free memory block is 2^10 pages.

The page size is not necessarily 4KB. Keep this in mind

their own address space using seccomp. Once seccomp is
