[PATCH 0/3] Make PATA transfer mode masks always being 32-bit

[Sergey Shtylyov <s.shtylyov@omp.ru>]

The PATA transfer mode masks (direct and packed) in libata are sometimes
declared as *unsigned int* and sometimes as *unsigned long* (which is a
64-bit type on 64-bit architectures), while the packed mask really only
uses 20 bits and the PIO/MWDMA/UDMA masks use up to 8 bits. Switching to
the uniform 32-bit masks saves siginificant amount of the object code...

Sergey Shtylyov (3):
  ata: make packed transfer mode masks *unsigned int*
  ata: make ata_device::{pio|mwdma|udma}_mask *unsigned int*
  ata: make ata_port_info::{pio|mwdma|udma}_mask *unsigned int*
