From 1e999736cafdffc374f22eed37b291129ef82e4e Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Wed, 11 Apr 2007 00:23:13 +0100 Subject: libata: HPA support Signed-off-by: Alan Cox Add support for ignoring the BIOS HPA result (off by default) and setting the disk to the full available size unless already frozen. Tested with various platforms/disks and confirmed to work with the Macintosh (which broke earlier) and ata_piix (breakage due to the LBA48 readback that Tejun fixed). For normal users this brings us, I believe, to feature parity with old IDE (and of course more featured in some areas too).
