Hello list,
On the x86 architecture, does kernel have distinction of low-
vs high- memory from the kalloc() point of view ?
Or the whole memory is flat and equally available for kernel allocation ?
And where is boundary between low/high memory exactly, if it exists ?
About DMA needing only low memory ... I see dma-related slabs in /proc/slabinfo
but I do not know whether this DMA limitation actually applies to the x86 architecture ?
Does it ?
Thanks
Guiseppe
