This patch adds support for ColdFire mcf5441x-family edma
module.
The ColdFire edma module is slightly different from fsl-edma,
so a new driver is added. But most of the code is common
between fsl-edma and mcf-edma so it has been collected into a
separate common module fsl-edma-common (patch 1/3).

Bay and Cherry Trail DSTDs represent a different set of devices depending
on which OS the device think it is booting. One set of decices for Windows
and another set of devices for Android which targets the Android-x86 Linux
kernel fork (which e.g. used to have its own display driver instead of
using the i915 driver).
Which set of devices we are actually going to get is out of our control,
this is controlled by the ACPI OSID variable, which gets either set through
an EFI setup option, or sometimes is autodetected. So we need to support
both.
This commit adds support for the 80862286 and 808622C0 ACPI HIDs which we
get for the first resp. second DMA controller on Cherry Trail devices when
OSID is set to Android.

Merge tag 'libnvdimm-for-4.19_dax-memory-failure' of gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm memory-failure update from Dave Jiang:
"As it stands, memory_failure() gets thoroughly confused by dev_pagemap
backed mappings. The recovery code has specific enabling for several
possible page states and needs new enabling to handle poison in dax
mappings.
In order to support reliable reverse mapping of user space addresses:
1/ Add new locking in the memory_failure() rmap path to prevent races
that would typically be handled by the page lock.
2/ Since dev_pagemap pages are hidden from the page allocator and the
"compound page" accounting machinery, add a mechanism to determine
the size of the mapping that encompasses a given poisoned pfn.
3/ Given pmem errors can be repaired, change the speculatively
accessed poison protection, mce_unmap_kpfn(), to be reversible and
otherwise allow ongoing access from the kernel.
A side effect of this enabling is that MADV_HWPOISON becomes usable
for dax mappings, however the primary motivation is to allow the
system to survive userspace consumption of hardware-poison via dax.
Specifically the current behavior is:
mce: Uncorrected hardware memory error in user-access at af34214200
{1}[Hardware Error]: It has been corrected by h/w and requires no further action
mce: [Hardware Error]: Machine check events logged
{1}[Hardware Error]: event severity: corrected
Memory failure: 0xaf34214: reserved kernel page still referenced by 1 users
[..]
Memory failure: 0xaf34214: recovery action for reserved kernel page: Failed
mce: Memory error not recovered

Memory failure: 0x20cb00: Killing dax-pmd:5421 due to hardware memory corruption
