The BIOS checks this bit to judge whether the mute on or off is sent via F8 key. Without changing this bit, the BIOS can be confused and may toggle the mute wrongly.

We should switch the macro in the linker script to INIT_TASK_DATA. (Sorry that I missed this in reviewing the patch). Since the macros are new, there is only one user of the INIT_TASK in vmlinux.lds.h, arch/mn10300/kernel/vmlinux.lds.S. However, we are currently using INIT_TASK_DATA for laying down an entire .data.init_task section. So rename that to INIT_TASK_DATA_SECTION. I would be worried about changing the meaning of INIT_TASK_DATA, but the old INIT_TASK_DATA implementation had no users, and in fact if anyone had tried to use it, it would have failed to compile because it didn't pass the alignment to the old INIT_TASK.

This caused regular IOs to fail prematurely when they were merged into failfast requests for readahead. Niel Lambrechts could trigger the problem semi-reliably on ext4 when resuming from STR. ext4 uses readahead when reading inodes and combined with the deterministic extra SATA PHY exception cycle during resume on the specific configuration, non-readahead inode read would fail causing ext4 errors. Please read the following thread for details. http://lkml.org/lkml/2009/5/23/21 This patch makes block layer reject merging if the failfast settings don't match. This is correct but likely to lower IO performance by preventing regular IOs from mingling into surrounding readahead requests. Changes to allow such mixed merges and handle errors correctly will be added later.

The driver is doing it's best on resetting the HBA, but sadly there's a firmware issue causing the firmware _not_ to abort or drop old commands. So the firmware will send us commands which we haven't accounted for, causing the driver to panic. With this patch we're just ignoring these commands as there is nothing we could be doing with them anyway.

If a tree block isn't referenced by its owner tree, full backrefs must be used for the pointers in it. When a tree block loses its owner tree's reference, backrefs for the pointers in it should be updated to full backrefs. Current btrfs_drop_snapshot misses the code that updates backrefs, so it's unsafe for general use. This patch adds backrefs update code to btrfs_drop_snapshot. It isn't a problem in the restricted form btrfs_drop_snapshot is used today, but for general snapshot deletion this update is required.

This is because we do not account for data we may use when doing the fallocate. This patch fixes the problem by properly reserving space, and then just freeing it when we are done. The reservation stuff was made with delalloc in mind, so its a little crude for this case, but it keeps the box from panicing.
