Mostly so people can see the work in progress. This enhances the encode function which isn't currently used in the base tree but is when using some of the testing tty patches. This resolves a problem with some hardware where applications got confusing information from the tty ioctls. Correct but confusing. In some situations asking for, say, 9600 baud actually gets you 9595 baud or similar near-miss values. With the old code this meant that a request for B9600 got a return of BOTHER, 9595 which programs interpreted as a failure. The new code now works on the following basis - If you ask for specific rate via BOTHER, you get a precise return - If you ask for a standard Bfoo rate and the result is close you get a Bfoo return - If you ask for a standard Bfoo rate and get something way off you get a BOTHER/rate return This seems to fix up the cases I've found where this broke compatibility.

In kernel-doc syntax, be a little flexible: allow whitespace between a function parameter name and the colon that must follow it, such as: @pdev : PCI device to unplug (This allows lots of megaraid kernel-doc to work without tons of editing.) Signed-off-by:

The patch to identify AIX disks and ignore them has caused at least one machine to fail to find the root partition on 2.6.19. The patch is: http://lkml.org/lkml/2006/7/31/117 The problem is some disk formatters do not blow away the first 4 bytes of the disk. If the disk we are installing to used to have AIX on it, then the first 4 bytes will still have IBMA in EBCDIC. The install in question was debian etch. Im not sure what the best fix is, perhaps the AIX detection code could check more than the first 4 bytes. The whole partition info for primary partitions is in this block: dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be )) All other data do not matter, beside the 0x55aa marker at the end of the first block.

Fix some RCU problem pointed out by Paul McKenney of IBM. These are: The wholesale move of the command receivers list into a new list was not safe because the list will point to the new tail during a traversal, so the traversal will never end on a reader if this happens during a read. Memory barriers were needed to handle proper ordering of the setting of the IPMI interface as valid. Readers might not see proper ordering of data otherwise. In ipmi_smi_watcher_register(), the use of the _rcu suffix on the list is unnecessary. This require the list_splice_init_rcu() patch previously posted. Signed-off-by:

This patch is in support of the IPMI driver. I have tested this with the IPMI driver changes coming in the next patch. Add a list_splice_init_rcu() function to splice an RCU-protected list into another list. This takes the sync function as an argument, so one would do something like: INIT_LIST_HEAD(&list); list_splice_init_rcu(&source, &dest, synchronize_rcu); The idea being to keep the RCU API proliferation down to a dull roar.

The 32bit and 64bit PARISC Linux kernels suffers from the problem, that the gettimeofday() call sometimes returns non-monotonic times. The easiest way to fix this, is to drop the PARISC-specific implementation and switch over to the generic TIME_INTERPOLATION framework. But in order to make it even compile on 32bit PARISC, the patch below which touches the generic Linux code, is mandatory. More information and the full patch with the parisc-specific changes is included in this thread: http://lists.parisc-linux.org/pipermail/parisc-linux/2006-December/031003.html As far as I could see, this patch does not change anything for the existing architectures which use this framework (IA64 and SPARC64), since "cycles_t" is defined there as unsigned 64bit-integer anyway (which then makes this patch a no-change for them).

Allow taint flags to be set from userspace by writing to /proc/sys/kernel/tainted, and add a new taint flag, TAINT_USER, to be used when userspace has potentially done something dangerous that might compromise the kernel. This will allow support personnel to ask further questions about what may have caused the user taint flag to have been set. For example, they might examine the logs of the realtime JVM to see if the Java program has used the really silly, stupid, dangerous, and completely-non-portable direct access to physical memory feature which MUST be implemented according to the Real-Time Specification for Java (RTSJ). Sigh. What were those silly people at Sun thinking? [akpm@osdl.org: build fix] [bunk@stusta.de: cleanup] Signed-off-by:
