Currently stacking devices do not have a queue directory in sysfs. However, many of the I/O characteristics like sector size, maximum request size, etc. are queue properties. This patch enables the queue directory for MD/DM devices. The elevator code has been modified to deal with queues that do not have an I/O scheduler. Signed-off-by:

Until now we have had a 1:1 mapping between storage device physical block size and the logical block sized used when addressing the device. With SATA 4KB drives coming out that will no longer be the case. The sector size will be 4KB but the logical block size will remain 512-bytes. Hence we need to distinguish between the physical block size and the logical ditto. This patch renames hardsect_size to logical_block_size. Signed-off-by:

Instead of queuing IPMB messages before channel initialization, just throw them away. Nobody will be listening for them at this point, anyway, and they will clog up the queue and nothing will be delivered if we queue them. Also set the current channel to the number of channels, as this value is used to tell if the channel information has been initialized. Signed-off-by:

It is possible for ide-cd to ignore ide_error()'s return value under some circumstances. Workaround it in ide_intr() and ide_timer_expiry() by checking if there is a device/port reset pending currently. Fixes bug #13345: http://bugzilla.kernel.org/show_bug.cgi?id=13345 Reported-by:

Since 2.6.26 we support UDMA66 on ATAPI devices requiring IVB quirk: commit 8588a2b7 ("ide: add SH-S202J to ivb_list[]") We also later added support for more such devices in: commit e97564f3 ("ide: More TSST drives with broken cable detection") and in: commit 3ced5c49 ("ide: add TSSTcorp CDDVDW SH-S202H to ivb_list[]") It turns out that such devices lack cable detection altogether (which in turn results in incorrect detection of 40-wire cables by our current cable detection strategy) so always handle them by trusting host-side cable detection only. v2: Model detection fixup from Martin.

The address range size calculation inside local_flush_tlb_kernel_range() is being truncated by a too small size variable holder on 64-bit systems. The truncated size can result in an erroneous tlbsize check that means we sit spinning inside a loop trying to flush a hige number of TLB entries. This is for all intents and purposes a system hang. Fix by using an appropriately sized valiable to hold the size. [Ralf: Greg's original patch submission identified the issue and fixed one instance in tlb-r4k.c but there there were several more. For consistency I also modified tlb-r3k.c even though that file is only used on 32-bit.] Signed-off-by:
