ide-disk: workaround for buggy HPA support on ST340823A (take 3)
This disk reports total number of sectors instead of maximum sector address in response to READ_NATIVE_MAX_ADDRESS command and also happily accepts SET_MAX_ADDRESS command with the bogus value. This results in +1 sector capacity being used and errors on attempts to use the last sector. ... hdd: Host Protected Area detected.         current capacity is 78165360 sectors (40020 MB)         native  capacity is 78165361 sectors (40020 MB) hdd: Host Protected Area disabled. ... hdd: reading: block=78165360, sectors=1, buffer=0xc1e63000 hdd: dma_intr: status=0x51 { DriveReady SeekComplete Error } hdd: dma_intr: error=0x10 { SectorIdNotFound }, LBAsect=78165360, sector=78165360 ... Add hpa_list[] table and workaround the issue in idedisk_check_hpa(). v2: * Add missing export and improve patch description a bit. v3: * Add list termination. (From Mikko) Fixes kernel bugzilla bug #8816. Thanks to Mikko for investigating the issue and helping with this patch.
