2.1 General allocator
'malloc' function accepts flags as a second argument. The flags are directly
passed to the underlying frame_alloc function.
1) If the flags parameter contains FRAME_ATOMIC, the allocator will not sleep.
The allocator CAN return NULL, when memory is not directly available.
The caller MUST check if NULL was not returned
2) If the flags parameter does not contain FRAME_ATOMIC, the allocator
will never return NULL, but it CAN sleep indefinitely. The caller
does not have to check the return value.
3) The maximum size that can be allocated using malloc is 128K
Rules 1) and 2) apply to slab_alloc as well. Using SLAB allocator
to allocate too large values is not recommended.
