The chan_get() function just adds unnecessary indirection to calling
the chan_create() call. The only added value it gives is the chan->ops
assignment, but that can equally well be done in the calling code.

The typical convention when having both a child and a parent channel

there's only one variable it's called chan. Rename the 'pchan'

Starting with commit 7d607f9170 ("mmc: host: omap_hsmmc: use
devm_regulator_get_optional() for vmmc") MMC on omap3 stopped working
for legacy booting.
This is because legacy booting sets up some of the resource in the
platform init code, and for optional regulators always seem to
return -EPROBE_DEFER for the legacy booting.
Let's fix the issue by checking for device tree based booting for
now. Then when omap3 boots in device tree only mode, this patch
can be just reverted.

cannot rely on the regulator status registers in hardare on 4430.

When using something like "ip maddr add ..." to add another unicast mac
address to the netdev, the mac address comes into the set_rx_mode handler
in the multicast list whether it is a unicast or multicast address.
This was confusing the code when it was trying to search for addresses
that needed to be deleted from the VSI, because it was looking for the
VSI unicast address in the netdev unicast list. The result was that a
new unicast address would get added to the VSI list and then immediately
removed, and would never actually make it down into the hardware.
This patch removes the separation from unicast and multicast in the search
for filters to be deleted. It also simplifies the logic a little with a
jump to the bottom of the loop when an address is found. Now it doesn't
matter which netdev list the address is hiding in, we'll check them all.

Previously, the driver could call this function and have only true/false
returned, but false could mean multiple things like failure to read
or link was down. This change allows the caller to get all return values
in the call chain bubbled back to the source, which keeps information about
failures from being lost.
Also, in some unlikely scenarios, the firmware can become slow to respond
to admin queue (AQ) queries for link state. Should the AQ time out,
the driver can detect the state and avoid a link change when there
may have been none.

Even though the VFs were gone, and the associated VSIs were removed, the

of the kernel.
To relieve this condition, explicitly stop all the rings associated with

Most distributions end up enabling SWIOTLB already with 32-bit
kernels due to the combination of CONFIG_HYPERVISOR_GUEST|CONFIG_XEN=y
as those end up requiring the SWIOTLB.
However for those that are not interested in virtualization and
run in 32-bit they will discover that: "32-bit PAE 4.2.0 kernel
(no IOMMU code) would hang when writing to my USB disk. The kernel
spews million(-ish messages per sec) to syslog, effectively
"hanging" userspace with my kernel.

Enabling it makes the problem go away.
N.B. With a6dfa128ce

we also have the important part of the SG macros enabled to make this
work properly - in case anybody wants to backport this patch.

The new amdgpu driver passes a user space pointer in a 64-bit structure
member, which is the correct way to do it, but it attempts to
directly cast it to a __user pointer in the kernel, which causes
a warning in three places:
drm/amd/amdgpu/amdgpu_cs.c: In function 'amdgpu_cs_parser_init':
drm/amd/amdgpu/amdgpu_cs.c:180:21: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
chunk_array_user = (uint64_t __user *)(cs->in.chunks);
This changes all three to add an intermediate cast to 'unsigned long'
as other drivers do. This avoids the warning and works correctly on
both 32-bit and 64-bit architectures.

perf_regs.c does not get built on Powerpc as CONFIG_PERF_REGS is false.
So the weak definition for 'sample_regs_masks' doesn't get picked up.
Adding perf_regs.o to util/Build unconditionally, exposes a redefinition
error for 'perf_reg_value()' function (due to the static inline version
in util/perf_regs.h). So use #ifdef HAVE_PERF_REGS_SUPPORT' around that
function.

A couple of fixes for the debugfs information on the register map,
fixing issues with very small reads potentially causing underflows and
