This patch will add a system calibration attribute for each channel. Using this option the user will have the ability to calibrate each channel for zero scale and full scale. It uses the iio_chan_spec_ext_info and IIO_ENUM to implement the functionality.

This patch exports the ad_sd_calibrate function in order to be able to call it from outside ad_sigma_delta. There are cases where the option to calibrate one channel at a time is necessary (ex. system calibration for zero scale and full scale).

The commit 473d12f7 ("iio: hid-sensor-attributes: Convert to use int_pow()") converted to use generic int_pow() helper. Though, the generic one returns 64-bit value and, in cases when it is used as divisor, it compels 64-bit division from compiler. In order to fix this, introduce a temporary 32-bit variable to hold the result of int_pow() and use it as divisor afterwards. In couple of cases, replace int_pow() with a predefined unit factors for time and frequency.

As Christoph said [1], "I'd much prefer to just use read_cache_page_gfp, and live with the fact that this allocates bufferheads behind you for now. I'll try to speed up my attempts to get rid of the buffer heads on the block device mapping instead. " This simplifies the code a lot and a minor thing is "no REQ_META (e.g. for blktrace) on metadata at all..."

As Christoph said [1], "vm_map_ram is supposed to generally behave better. So if it doesn't please report that that to the arch maintainer and linux-mm so that they can look into the issue. Having user make choices of deep down kernel internals is just a horrible interface. Please talk to maintainers of other bits of the kernel if you see issues and / or need enhancements.
