Since patch "i2c / ACPI: Use 0 to indicate that device does not have
interrupt assigned" [1], 0 is not a valid i2c client irq anymore, so
change all driver's checks accordingly.
The same issue occurs when the device is instantiated via device tree
with no IRQ, or from the i2c sysfs interface, even before the patch
above.

The functionality of ext3 is fully supported by ext4 driver. Major
distributions (SUSE, RedHat) already use ext4 driver to handle ext3
filesystems for quite some time. There is some ugliness in mm resulting
from jbd cleaning buffers in a dirty page without cleaning page dirty
bit and also support for buffer bouncing in the block layer when stable
pages are required is there only because of jbd. So let's remove the
ext3 driver. This saves us some 28k lines of duplicated code.

Currently when some error happened in ->acquire_dquot(), dqget() just
returned NULL. That was indistinguishable from a case when e.g. someone
run quotaoff and so was generally silently ignored. However
->acquire_dquot() can fail because of ENOSPC or EIO in which case user
should better know. So propagate error up from ->acquire_dquot properly.

Currently, rl6231_pll_calc provide a working PLL parameters for
given freq_in and freq_out. However, in some cases it is not the
perfect parameter. For example if freq_in = 19200000 and freq_out
= 24576000, the calculated parameter will gengrate 24.5647 MHz
which is not exactly the same as what we need. But the PLL can
output 24.576 MHz as exactly what we expect if we set the best
PLL parameter.
To improve it, we put the best match parameters in a preset table.
We can search the preset table first, if there is no preset parameter
for the given freq_in and freq_out, we can still calculate a working
PLL parameter.

When we scan a PCI bus, we read PCI-PCI bridge window registers with
pci_read_bridge_bases() so we can validate the resource hierarchy. Most
architectures call pci_read_bridge_bases() from pcibios_fixup_bus(), but
PCI-PCI bridges are not arch-specific, so this doesn't need to be in
arch-specific code.
Call pci_read_bridge_bases() directly from the PCI core instead of from
arch code.
For alpha and mips, we now call pci_read_bridge_bases() always; previously
we only called it if PCI_PROBE_ONLY was set.
