David Miller reported soft lockup false-positives that trigger
on NOHZ due to CPUs idling for more than 10 seconds.The solution is touch the softlockup watchdog when we return from
idle. (by definition we are not 'locked up' when we were idle)http://bugzilla.kernel.org/show_bug.cgi?id=9409

ocfs2_truncate() and ocfs2_remove_inode_range() had reversed their "set
i_size" arguments to ocfs2_truncate_inline(). Fix things so that truncate
sets i_size, and punching a hole ignores it.This exposed a problem where punching a hole in an inline-data file wasn't
updating the page cache, so fix that too.Signed-off-by: Mark Fasheh

This was causing us to prematurely push out inline data by one byte.

The existing bug statement didn't take into account unhashed dentries which
might not have a cluster lock on them. This could happen if a node exporting
the file system via NFS is rebooted, re-exported to nfs clients and then
unmounted. It's fine in this case to not have a dentry cluster lock.Just remove the bug statement and replace it with an error print, which
does the proper checks. Though we want to know if something has happened
which might have prevented a cluster lock from being created, it's
definitely not necessary to panic the machine for this.Signed-off-by: Mark Fasheh

Enable expensive bitmap scanning only if DEBUG option is enabled.
The bitmap scanning quite loads the CPU and on my machine the write
throughput of dd if=/dev/zero of=/ocfs2/file bs=1M count=500 conv=sync
improves from 37 MB/s to 45.4 MB/s in local mode...Signed-off-by: Jan Kara

If the inode block isn't valid then we don't want to print the value from
that, instead print the block number which was passed in (which should
always be correct). Also, turn this into a debug print for now - folks who
hit an actual problem always have other logs indicating what the source is.Signed-off-by: Mark Fasheh

Add pci_enable_device() to aec62xx probe function
before doing any I/O.Original probe function tries to read from device's
PCI region 4 before calling ide_setup_pci_device().
Since the device is not enabled at this point,
on machines that have no firmware PCI initialization
(e.g. ASUS WL-700gE router), corresponding PCI BAR
is 0 and the following inb() causes a kernel oops.Signed-off-by: Aleksandar Radovanovic

There is a problem in some hardware where the kernel will stall for
35 seconds waiting for disks that don't exist. This patch will skip
waiting for the BSY-bit on IDE drives to go away if you set "hdx=noprobe"
as a kernel option and the disk is not marked as 'present' (like when
you set the geometry by hand).If no noprobe-option is set the code will work (more or less) as the
original but if set the code will skip the ide_wait_not_busy() for
that drive. Even if there would be a drive there and it is still busy
afterwards it should not matter since it isn't probed for later.The code also honors the MAX_DRIVES variable instead of assuming that
there will be two harddrives on the bus.Bart: minor cleanups
