ata: make transfer mode masks *unsigned int*
The packed transfer mode masks and also the {pio|mwdma|udma}_mask fields of *struct*s ata_device and ata_port_info are declared as *unsigned long* (which is a 64-bit type on 64-bit architectures) but actually the packed masks occupy only 20 bits (7 PIO modes, 5 MWDMA modes, and 8 UDMA modes) and the PIO/MWDMA/UDMA masks easily fit into just 8 bits each, so we can safely use (always 32-bit) *unsigned int* variables instead. This saves 745 bytes of object code in libata-core.o alone, not to mention LLDDs... Signed-off-by: Sergey Shtylyov <s.shtylyov@omp.ru> Signed-off-by: Damien Le Moal <damien.lemoal@opensource.wdc.com>
