I noticed that almost all architectures implemented exactly the same
sys32_sysinfo... except parisc, where a bug was to be found in handling of
the uptime. So let's remove a whole whack of code for fun and profit.
Cribbed compat_sys_sysinfo from x86_64's implementation, since I figured it
would be the best tested.This patch incorporates Arnd's suggestion of not using set_fs/get_fs, but
instead extracting out the common code from sys_sysinfo.Cc: Christoph Hellwig

A variety of (mostly) innocuous fixes to the embedded kernel-doc content in
source files, including:* make multi-line initial descriptions single line
* denote some function names, constants and structs as such
* change erroneous opening '/*' to '/**' in a few places
* reword some text for claritySigned-off-by: Robert P. J. Day

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 returnThis 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: Randy Dunlap

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.Signed-off-by: Olaf Hering

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.

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).Signed-off-by: Helge Deller

It makes no sense to me to export invalidate_inode_pages() and not
