This adds a separate SERIAL_8250_ACPI config option and makes the
8250_acpi.c code dependent on ACPI_BUS (since acpi_bus_register_driver()
is a prerequisite).

I don't understand what was on the mind of Procom programmers,
why do all this inverted logic? Its plain confusing, revert it.
Thanks to DaveM for asking if the logic was inverted, I should
have killed this weird stuff a long time ago :-\

With this we make it easier to write correct network families as less
details need to be taken into account, as well in the current state we
make the non-refcounting protocols (the ones still keeping deliver_to_old_ones
in the tree) suck less. 8)

Left a WARN_ON in sk_del_node_init for a while, so that we can catch cases
where we're using __sock_put on a struct sock that has refcnt == 1, which
is not the case for all the ones I tested.

SECURITY_INIT doesn't work when it is placed inside an output section.
Use our own version instead.

All current CPUs of ARMv5 or later can have ECC memory and can
support write allocations.

Noticed by Jun Sun.

Fix a couple of minor build errors caused by the recent system device
changes.

Ensure virt_addr_valid(x) works correctly for pointers.
Add comments indicating that drivers should not use virt_to_phys
and/or __pa to obtain an address for DMA.

This cset makes use of our AMBA device model, thereby allowing the
"KMI" PrimeCell driver to become ARM platform independent.

The ICS525 clock chip is used in several different parts of the
Integrator platform.  Rather than duplicate the code, separate it
out so everyone can use it.

Boot ROMs have talked TFTP forever.  Some do it over USB now.

  - switch to usb_buffer_alloc

We cannot sensibly support O_DIRECT reads or writes when all writes are
journalled.

This is because the VFS explicitly avoids syncing the file metadata during
O_DIRECT reads and writes.  ext3 with journalled data will leave pending
changes in memory and they will overwrite the results of O_DIRECT writes, and
O_DIRECT reads will not return the latest data.

Setting the a_op to null will cause opens and fcntl(F_SETFL) to return
-EINVAL if O_DIRECT is requested.

Minro tweak: once log_wait_for_space() has created sufficient space in the
journal to start the new handle, hang onto the spinlock as
start_this_handle() loops around to reevaluate the journal's state.

It prevents anyone else from zooming in and stealing the space we just made.

There are various places in which JBD is starting a commit against a
transaction without sufficient locking in place to ensure that that
transaction is still alive.

Change it so that log_start_commit() takes a transaction ID instead.  Make
the caller take a copy of that ID inside the appropriate locks.

log_do_checkpoint is playing around with a transaction pointer without enough
locking to ensure that it is valid.  Fix that up by revalidating the
transaction after acquiring the right locks.

With data=ordered it is often the case that a quick write-and-truncate will
leave large numbers of pages on the page LRU with no ->mapping, and attached
buffers.  Because ext3 was not ready to let the pages go at the time of
truncation.

These pages are trivially reclaimable, but their seeming absence makes the VM
overcommit accounting confused (they don't count as "free", nor as
pagecache).  And they make the /proc/meminfo stats look odd.

So what we do here is to try to strip the buffers from these pages as the
buffers exit the journal commit.

This was a flag which said "the transaction's time is active".
timer_pending() could have told us that, but in fact there is no need to
query it at all.

Fix various problems which cropped up due to MAP_SHARED traffic on
data=journal with blocksize < PAGE_CACHE_SIZE.

All relate to handling the "pending truncate" buffers outside i_size.
