This change adds support for a single preallocated cl_env per CPU which can be used in circumstances where reschedule is not possible. Currently this interface is only used by the ll_releasepage function.

This reverts a patch that was merged before lustre client was introduced into the stagign tree, so it's not in the history. The performance dropped a lot when memory reclaim process kicked in as ll_releasepage() was called to destroy lustre pages. It turned out that big overhead to allocate cl_env and keys on the fly so we have to revert this patch. The original problem for the reverted patch would be solved in a follow on patch instead.

Allocating a big hash table using the formula for osd does not really work for clients. We will create new hash table for each mount on a single client which is a lot of memory more than expected.

the dgnc_offset_table has a same value with (1 << port). So I tried to replace dgnc_offset_table array with 1 << port.

This function assumes that the async subdevice has a cancel() function. It looks like all the current comedi drivers implement a cancel() for the async subdevices except for the dt2814 analog input usbdevice. Fix comedi_handle_events() so it does not try to call a non-existent cancel() function. Add a dev_warn() to __comedi_device_postconfig_async() so that any new driver authors will be reminded to implement the cancel().

timed_output was only used by the Android vibrator HAL which has now learned how to use LED triggers instead[1]. Any users of it in AOSP are on ancient kernels.

The fields 'switch_no' and 'internal_port_no' were originally added to the visor_device struct in preparation of removing the 'device_info' struct in the now removed 'uislib' library.
