From 650d841d9e053a618dd8ce753422f91b493cf2f6 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Fri, 25 Jan 2008 22:17:06 +0100 Subject: ide: add struct ide_taskfile (take 2) * Don't set write-only ide_task_t.hobRegister[6] and ide_task_t.hobRegister[7] in idedisk_set_max_address_ext(). * Add struct ide_taskfile and use it in ide_task_t instead of tfRegister[] and hobRegister[]. * Remove no longer needed IDE_CONTROL_OFFSET_HOB define. * Add #ifndef/#endif __KERNEL__ around definitions of {task,hob}_struct_t. While at it: * Use ATA_LBA define for LBA bit (0x40) as suggested by Tejun Heo. v2: * Add missing newlines. (Noticed by Sergei) * Use ~ATA_LBA instead of 0xBF. (Noticed by Sergei) * Use unnamed unions for error/feature and status/command. (Suggested by Sergei). There should be no functionality changes caused by this patch.
