atmel-mci: Initialize BLKR before sending data transfer command
The atmel-mci driver sometimes fails data transfers like this:
mmcblk0: error -5 transferring data
end_request: I/O error, dev mmcblk0, sector 2749769
end_request: I/O error, dev mmcblk0, sector 2749777
It turns out that this might be caused by the BLKR register (which
contains the block size and the number of blocks being transfered) being
initialized too late. This patch moves the initialization of BLKR so
that it contains the correct value before the block transfer command is
sent.
This error is difficult to reproduce, but if you insert a long delay
(mdelay(10) or thereabouts) between the calls to atmci_start_command()
and atmci_submit_data(), all transfers seem to fail without this patch,
while I haven't seen any failures with this patch.

x86 ACPI: Blacklist two HP machines with buggy BIOSes
There is a bug in the BIOSes of some HP boxes with AMD Turions which
connects IO-APIC pins with ACPI thermal trip points in such a way that
if the state of the IO-APIC is not as expected by the (buggy) BIOS, the
thermal trip points are set to insanely low values (usually all of them
become 16 degrees Celsius). As a result, thermal throttling kicks in
and knock the system down to its shoes.
Unfortunately some of the recent IO-APIC changes made the bug show up.
To prevent this from happening, blacklist machines that are known to be

remove <linux/i2c/twl4030-rtc.h>
Remove <linux/i2c/twl4030-rtc.h> by moving all the relevant contents
into the driver itself, and removing the rest. Stuff removed included
many useless bitmasks, and remnants of the platform data hook.
Add markers inside the rtc driver to split sections apart: first
data structure declarations, then the RTC driver, then platform bus
glue for it all.
There's still an issue with the twl4030-pwrirq.h registers ... this
driver has no business touching them! This patch at least switches
away from having private versions of those register definitions, and
removes some unnecessary accesses to them.
No functional changes, just shrinkage.

atmel-mci: Don't overwrite error bits when NOTBUSY is set
After a data error, we wait for the NOTBUSY bit to be set so that we can
be sure the data transfer is completely finished. However, when NOTBUSY
is set, the interrupt handler copies the contents of SR into
data_status, overwriting any error bits we may have detected earlier.
To avoid this, initialize data_status to 0 before starting a request, and
don't overwrite it unless it still contains 0.
