Since acpi_cpufreq_resume and speedstep_resume appear to return 0 upon
success, it seems like the attached patch is what the desired behavior
would be.  Otherwise, cpufreq_resume() always prints an error and exits
early if using a cpufreq_driver that supports resume.

This was noticed on PPC, which triggers an MCE in case of invalid IO port

Fix some bugs in device-mapper handling of 64-bit values, replacing
dm_div_up() and dm_round_up() inlines with macros and removing some
avoidable divisions of 64-bit numbers.

The mirror region size is the granularity used to manage and monitor the
data copying, typically 512KB, so 32 bits (of sectors) should be plenty to
hold this.

Taken together with the two earlier patches:
  "fix TB stripe data corruption" (a missing cast) and
  "stripe_width should be sector_t",
I've now had 3 independent reports that this fixes device-mapper
for devices with large stripes.

Still awaiting test results for dm-crypt and dm-raid1.

Not that low-level code really tends to care, but since loff_t is
a signed 64-bit entity and size_t is unsigned (and potentially
64-bit), mixing the two isn't very well-defined.. 

The actual user copy will do them too, but only for the
range that ends up being actually copied. That hides
bugs when the range has been clamped by file size or other
issues.

I accidentally introduced a leak in there, because the end_io function
doesn't do a bio_put() like most others. Fortunately it's not critical,
as it only happens on the md super block read. So just drop the initial

it has completed.

On the one hand APM isn't enabled on all laptops.
On the other hand, this also affects regular PCs with APM support (or
using a distribution kernel with APM support).

The time for the !APM case was already increased from 30msec in 2.4 .
Isn't there a timeout that is suitable for all cases?
