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...

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.

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.

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.

The intent behind siimage_reset() was probably to hard reset the interface and
the SATA PHY but as the code writes to two reserved bits instead, it obviously
has been ineffective from the start. So, just remove it.

if blktrace program segfault it will not be able
to call BLKTRACETEARDOWN. Now if we run the blktrace
again that would result in a failure to create the
block/<device> debugfs directory.This will result
in blk_remove_root() to be called which will set
blk_tree_root to NULL. But the debugfs block dir
still exist because it contain subdirectory.
Now if we try to fix it using BLKTRACETEARDOWN
it won't work because blk_tree_root is NULL.
Fix the same.
Tested as below
root@qemu-image:/home/kvaneesh/blktrace# ./blktrace -d /dev/hdc
