Comment (by pulkomandy):
I would have used the other parameter to create area, which is currently
{{{B_ANY_KERNEL_ADDRESS}}}. There already is a {{{B_BASE_ADDRESS}}} there,
and I think it would make sense to use a {{{B_MAX_ADDRESS}}} (in
combination with the standard {{{B_CONTIGUOUS}}} flag).
@axeld: as mentionned, some hardware needs a 32-bit limit, for which we
already had a specific flag. This card needs 28bits, emuxki needs 31bits.
We also have a flag for 24 bits (for which we have another specific flag,
{{{B_LOMEM}}}) and some old ISA stuff with DMA needs 16bits or 20bits
(which we don't have support for yet). We could have everything use
{{{B_LOMEM}}} but this is putting unneeded memory pressure on this rather
small address space, so I think a generic solution at create_area level
would be more helpful.
