libata-sff: use ATAPI_{COD|IO}

2012-01-09T00:14:58+00:00

atapi_pio_bytes() uses bare numbers for the ATAPI interrupt reason bits despite
these are #define'd in .

ide/ata: Add module.h to the implicit modular users

2011-10-31T23:31:37+00:00

A pending cleanup will mean that module.h won't be implicitly
everywhere anymore.  Make sure the modular drivers in the ide dir
are actually calling out for  explicitly in advance.

libata: make ata_sff_data_xfer_noirq() work with 32-bit PIO

2011-10-14T17:37:31+00:00

Always use ata_sff_data_xfer32() in ata_sff_data_xfer_noirq()
so the latter can be also used for host controllers supporting
32-bit PIO operations.

It is a completely safe thing to do because if 32-bit PIO is
not supported or enabled ata_sff_data_xfer32() will fallback
to a standard method.

libata: reduce ata_pci_[sff,bmdma]_init_one() size

2011-10-14T17:01:17+00:00

Turn both helpers (which are used only during LLDs initialization
time and thus are not performance sensitive) into wrappers around
the new ata_pci_init_one() function, this cuts 20 LOC and saves
~1.1k of the output code size (x86-64):

libata: clear PIO pad area

2011-10-08T03:46:25+00:00

ata_sff_data_xfer[32]() use pad area if the transfer size isn't
multiple of transfer size; however, this area wasn't cleared and
garbage data in pad area could be transferred to the device.  Make
sure the pad area is cleared.

ata: Convert ata__printk(KERN_ to ata__

2011-07-23T21:57:36+00:00

Saves text by removing nearly duplicated text format strings by
creating ata__printk functions and printf extension %pV.

ata defconfig size shrinks ~5% (~8KB), allyesconfig ~2.5% (~13KB)

Format string duplication comes from:

 #define ata_link_printk(link, lv, fmt, args...) do { \
       if (sata_pmp_attached((link)->ap) || (link)->ap->slave_link)    \
               printk("%sata%u.%02u: "fmt, lv, (link)->ap->print_id,   \
                      (link)->pmp , ##args); \
       else \
               printk("%sata%u: "fmt, lv, (link)->ap->print_id , ##args); \
       } while(0)

Coalesce long formats.
