To avoid registering notification handler again,
introduce a notifier chain in global system notifier handler
and use it in dock driver.

In some BIOSes, every _STA method call will send a notification again,
this cause freeze. And in some BIOSes, it appears _STA should be called
after _DCK. This tries to avoid calls _STA, and still keep the device
present check.

The Freescale Elo DMA driver runs an internal self-test before registering
the channels with the DMA engine. This self-test has a fundemental flaw in
that it calls the DMA engine's callback functions directly before the
registration. However, the registration initializes some variables that the
callback functions uses, namely the device struct.
The code works today because there are two device structs: the one created
by the DMA engine, and one created by the Open Firmware (OF) subsystem. The
self-test currently uses the device struct created by OF. However, in the
future, some of the device structs created by OF will be eliminated.
This means that the self-test will only have access to the device struct
created by the DMA engine. But this device struct isn't initialized when
the self-test runs, and this causes a kernel panic.
Since there is already a DMA test module (dmatest), the internal self-test
code is not useful anyway. It is extremely unlikely that the test will fail
in normal usage. It may have been helpful during development, but not any more.

When we use > 4KB's page size the original definition is not consistent
with PGDIR_SIZE. For exeample, if we use 16KB page size the PGDIR_SHIFT is
(14-2) + 14 = 26, PGDIR_SIZE is 2^26，so the PTRS_PER_PGD should be:
2^32/2^26 = 2^6
but the original definition of PTRS_PER_PGD is 4096 (PGDIR_ORDER = 0).
So, this definition needs to be consistent with the PGDIR_SIZE.
And the new definition is consistent with the PGD init in pagetable_init().

When setting the direction of one GPIO pin we have to keep the state of the
other pins, hence use binary OR. Also gpio_direction_output() wants to set an
initial value, so add that too.
This fixes a problem with the USB power switch on mtx-1 boards.

Previously mballoc created a separate set of functions for each proc

This patch (as1135) essentially reverts the major parts of two earlier
patches to usbcore, because they ended up causing a regression.
Trying to recover from transient communication errors can lead to
other problems, because operations that failed during the error period
are not always retried. The simplest example is the initial
Set-Config request sent after device enumeration; if it gets lost then
it will not be retried and the device will remain unconfigured.
This patch restores the old behavior in which any port disconnect or
port disable causes the entire device structure to be removed, fixing a
reported regression.
