Manuel Lauss 963accbc82 MIPS: Alchemy: change dbdma to accept physical memory addresses
DMA can only be done from physical addresses; move the "virt_to_phys"
source/destination buffer address translation from the dbdma queueing
functions (since the hardware can only DMA to/from physical addresses)
to their respective users.

Remove dbdma compat macros, move remaining users over to default
queueing functions and -flags.

(Queueing function signature has changed in order to give
 a build failure instead of silent functional changes due
 to the no longer implicitly specified DDMA_FLAGS_IE flag)

Martin K. Petersen 086fa5ff08 block: Rename blk_queue_max_sectors to blk_queue_max_hw_sectors
The block layer calling convention is blk_queue_<limit name>.
blk_queue_max_sectors predates this practice, leading to some confusion.
Rename the function to appropriately reflect that its intended use is to
set max_hw_sectors.

Also introduce a temporary wrapper for backwards compability.  This can
be removed after the merge window is closed.
