This creates a new RTC-framework driver for the RTC/calendar module
found in various OMAP chips, giving a more correct/standard replacement
for the older drivers/char/omap-rtc.c driver.  Differences include:

 - much smaller/simpler, because it reuses shared infrastructure
 - the RTC name will normally be "rtc0" not "rtc"
 - the /dev node has a different major and minor numbers
 - RTC_ALM_SET handled as on PCs (alarm within 24 hours)
 - RTC_WKALM_SET handled as on PCs (alarm within this century)
 - epoch not changeable (why bother)
 - rtc alarm may optionally be a system wakeup event (board-specific)

If you use udev and statically link this, some init script can just create
a symbolic link (rtc -> rtc0) so tools like "hwclock" will work as usual.
Or, updates to hwclock (and busybox) are available which teach it to use
the /dev/rtc0 path as a backup, and to support "hwclock --file=/dev/rtc0".

ARM11 can't access the IVA interrupt controller from
IVA slave port.

From Richard Woodruff:

"The 0x40000000 is an IVA-ARM7 local bus address.
The IVA-INTC is NOT accessible through the IVA-L3-Slave Port.
The current TRM does say this directly and indirectly in a few spots and
in figures."

Some things are probably broken right now with the generic irq
code update.

Since ab7ad9fe sti-console puts
crap into STI if serial console is configured as a preferred console.

This is due to uninitialized sti_console_channel (0 is a bad channel
value).

The fix is to check the STI channel value before registering the
console driver.

While busy-waiting for completion, check the hardware after scheduling;
don't schedule and then immediately check the _timeout_.  If the yield()
took a long time (as it does on my OLPC prototype board when it's busy),
we'd report a timeout even though the hardware was now ready.

This fixes it, and also switches the yield() for a cond_resched() because
we don't actually want to be _that_ nice about it.  I see nice
tightly-packed SMBus transactions now, rather than waiting for milliseconds
between successive phases.

Actually, we shouldn't be busy-waiting here at all.  We should be using
interrupts.  That's an exercise for another day though.

I saw an oops down this path when trying to create a new file on a UDF
filesystem which was internally marked as readonly, but mounted rw:

udf_create
        udf_new_inode
                new_inode
                        alloc_inode
                        	udf_alloc_inode
                udf_new_block
                        returns EIO due to readonlyness
                iput (on error)
                        udf_put_inode
                                udf_discard_prealloc
                                        udf_next_aext
                                                udf_current_aext
                                                        udf_get_fileshortad
                                                                OOPS

the udf_discard_prealloc() path was examining uninitialized fields of the
udf inode.

udf_discard_prealloc() already has this code to short-circuit the discard
path if no extents are preallocated:

        if (UDF_I_ALLOCTYPE(inode) == ICBTAG_FLAG_AD_IN_ICB ||
                inode->i_size == UDF_I_LENEXTENTS(inode))
        {
                return;
        }

so if we initialize UDF_I_LENEXTENTS(inode) = 0 earlier in udf_new_inode,
we won't try to free the (not) preallocated blocks, since this will match
the i_size = 0 set when the inode was initialized.

A patch in -mm kernel correct the parsing of "address resources" of pnpacpi.
Before we assumed it was memory only, but it could be also IO.

But this change show an hidden bug : some resources could be producer type
that are not handled by pnp layer.  So we should ignore the producer
resources.

This patch fixes bug 6292 (http://bugzilla.kernel.org/show_bug.cgi?id=6292).
Some devices like PNP0A03 have 0xd00-0xffff and 0x0-0xcf7 as IO producer
resources.

Before correcting "address resources" parsing, it was seen as memory and was
harmless, because nobody tried to reserve this memory range as it should be
IO.

With the correction it become IO resources, and make failed all others device
that want to register IO in this range and use pnp layer (like a ISA sound
card).

The solution is to ignore producer resources

reiserfs_write_full_page does zero bytes in the file past eof, but it may
call get_block on those buffers as well.  On machines where the page size
is larger than the blocksize, this can result in mmaped files incorrectly
growing up to a block boundary during writepage.

The fix is to avoid calling get_block for any blocks that are entirely past
eof
