Allocate frames, linearly in physical memory, with an extra set of flags. If the flags contain
PARTIAL_ALLOC
, this will result in physalloc3

.
Allocate frames, linearly in physical memory, with an extra set of flags. If the flags contain
PARTIAL_ALLOC
, the min
parameter specifies the number of frames that have to be allocated
for this operation to succeed. The return value is the offset of the first frame, and min
is
overwritten with the number of frames actually allocated.
