We currently have two symbols to control compilation the MFD subsystem,
MFD_SUPPORT and MFD_CORE. The MFD_SUPPORT is actually not required
at all, it only hides the submenu when not set, with the effect that
Kconfig warns about missing dependencies when another driver selects
an MFD driver while MFD_SUPPORT is disabled. Turning the MFD submenu
back from menuconfig into a plain menu simplifies the Kconfig syntax
for those kinds of users and avoids the surprise when the menu
suddenly appears because another driver was enabled that selects this
symbol.

Refactor the GPADC interface to avoid bugs in calling code:

- ab8500_gpadc_[convert|read_raw|ad_to_voltage] clarifies
  each functions use case, *convert wraps *read_raw, and we
  can access raw ADC values properly.
- Renamed gpadc function arguments from "input" to "channel" to
  clarify use, so we don't get confused again.

  dm kcopyd: fix job_pool leak

Commit 4b239f45 ("x86-64, mm: Put early page table high") causes a S4
regression since 2.6.39, namely the machine reboots occasionally at S4
resume.  It doesn't happen always, overall rate is about 1/20.  But,
like other bugs, once when this happens, it continues to happen.

This patch fixes the problem by essentially reverting the memory
assignment in the older way.

Fix memory leak introduced by commit a6e50b40
(dm snapshot: skip reading origin when overwriting complete chunk).

When allocating a set of jobs from kc->job_pool, job->master_job must be
set (to point to itself) so that the mempool item gets freed when the
master_job completes.

master_job was introduced by commit c6ea41fb
(dm kcopyd: preallocate sub jobs to avoid deadlock)
