      ide-disk: workaround for buggy HPA support on ST340823A (take 3) · b0244a00

      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.
