Minor number 0 (under the raw major) is reserved for the rawctl device
file, which is used to query, set, and unset raw device bindings. However,
the ioctl interface does not protect the user from specifying a raw device
with minor number 0:
$ sudo ./raw /dev/raw/raw0 /dev/VolGroup00/swap
/dev/raw/raw0: bound to major 253, minor 2
$ ls -l /dev/rawctl
ls: /dev/rawctl: No such file or directory
$ ls -l /dev/raw/raw0
crw------- 1 root root 162, 0 Jan 12 10:51 /dev/raw/raw0
$ sudo ./raw -qa
Cannot open master raw device '/dev/rawctl' (No such file or directory)
As you can see, this prevents any further raw operations from
succeeding. The fix (from Steve Fernandez) is quite simple--do not
allow the allocation of minor number 0.

gcc emits this warning:
kernel/auditfilter.c: In function 'audit_filter_user':
kernel/auditfilter.c:1611: warning: 'state' is used uninitialized in this function
I tend to agree with gcc - there are a couple of plausible exit paths from
audit_filter_user_rules() where it does not set 'state', keeping the
variable uninitialized. For example if a filter rule has an AUDIT_POSSIBLE
action. Initialize to 'wont audit'. Fix whitespace damage too.

In the rare case where we have skipped orphan inode processing due to a
readonly block device, and the block device subsequently changes back to
read-write, disallow a remount,rw transition of the filesystem when we have an
unprocessed orphan inodes as this would corrupt the list.
Ideally we should process the orphan inode list during the remount, but that's
trickier, and this plugs the hole for now.

This is an "RTC framework" driver for the "CMOS" RTCs which are standard on
PCs and some other platforms. That's MC146818 compatible silicon.
Advantages of this vs. drivers/char/rtc.c (use one _or_ the other, only
one will be able to claim the RTC irq) include:
- This leverages both the new RTC framework and the driver model; both
PNPACPI and platform device modes are supported. (A separate patch
creates a platform device on PCs where PNPACPI isn't configured.)
- It supports common extensions like longer alarms. (A separate patch
exports that information from ACPI through platform_data.)
- Likewise, system wakeup events use "real driver model support", with
policy control via sysfs "wakeup" attributes and and using normal rtc
ioctls to manage wakeup. (Patch in the works. The ACPI hooks are
known; /proc/acpi/alarm can vanish. Making it work with EFI will
be a minor challenge to someone with e.g. a MiniMac.)
It's not yet been tested on non-x86 systems, without ACPI, or with HPET.
And the RTC framework will surely have teething pains on "mainstream"
PC-based systems (though must embedded Linux systems use it heavily), not
limited to sorting out the "/dev/rtc0" issue (udev easily tweaked). Also,
the ALSA rtctimer code doesn't use the new RTC API.
Otherwise, this should be a no-known-regressions replacement for the old
drivers/char/rtc.c driver, and should help the non-embedded distros (and
the new timekeeping code) start to switch to the framework.
Note also that any systems using "rtc-m48t86" are candidates to switch over
to this more functional driver; the platform data is different, and the way
bytes are read is different, but otherwise those chips should be compatible.

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.

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.

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.

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).
