Since commit 28c56ea1431421dec51b7b229369e991481453df
(powerpc/usb: fix bug of kernel hang when initializing usb)
the kernel crashes on mpc5121e. mpc5121e doesn't have system interface
registers, accessing this register address space cause the machine check
exception and a kernel crash:

The BCJ filters were meant to be enabled already on these
archs, but the xz_wrap.sh script was buggy. Enabling the
filters should give smaller kernel images.
xz_wrap.sh will now use $SRCARCH instead of $ARCH to detect
the architecture. That way it doesn't need to care about the
subarchs (like i386 vs. x86_64) since the BCJ filters don't
care either.

This patch (as1544) fixes a problem affecting some EHCI controllers.
They can generate interrupts whenever the STS_FLR status bit is turned
on, even though that bit is masked out in the Interrupt Enable
register.
Since the driver doesn't use STS_FLR anyway, the patch changes the
interrupt routine to clear that bit whenever it is set, rather than
leaving it alone.

Newer BKDG[1] versions recommend a different initialization value for
the running average range register in the northbridge. This improves
the power reading by avoiding counter saturations resulting in bogus
values for anything below about 80% of TDP power consumption.
Updated BIOSes will have this new value set up from the beginning,
but meanwhile we correct this value ourselves.
This needs to be done on all northbridges, even on those where the
driver itself does not register at.
This fixes the driver on all current machines to provide proper
values for idle load.

This reverts commit 6fe0d0628245fdcd6fad8b837c81e8f7ebc3364d.
Paul bisected this regression.
The conversion was done blindly and is wrong, as it does not provide a
primary handler to disable the level type irq on the device level.
Neither does it set the IRQF_ONESHOT flag which handles that at the irq
line level. This can't be done as the interrupt might be shared, though
we might extend the core to force it.
So an interrupt on this line will wake up the thread, but immediately
unmask the irq after that. Due to the interrupt being level type the
hardware interrupt is raised over and over and prevents the irq thread
from handling it. Fail.
request_irq() unfortunately does not refuse such a request and the patch
was obviously never tested with real interrupts.

There are some softwares (Kaffeine and likely xine) that uses a
DVBv5 call to switch to DVB-S2, but expects that a DVBv3 call to
switch back to DVB-S. Well, this is not right, as a DVBv3 call
doesn't know anything about delivery systems.
However, as, by accident, this used to work, we need to restore its
behavior, in order to avoid regressions with those softwares.

If drivers try to obtain pinctrl handles for a pin controller that
has not yet registered to the subsystem, we need to be able to
back out and retry with deferred probing. So let's return
-EPROBE_DEFER whenever this location fails. Also downgrade the
errors to info, maybe we will even set them to debug once the
deferred probing is commonplace.

Most of the SoC drivers implement list_groups() and list_functions()
routines for pinctrl and pinmux. These routines continue returning
zero until the selector argument is greater than total count of
available groups or functions.
This patch replaces these list_*() routines with get_*_count()
routines, which returns the number of available selection for SoC
driver. pinctrl layer will use this value to check the range it can
choose.
This patch fixes all user drivers for this change. There are other
routines in user drivers, which have checks to check validity of
selector passed to them. It is also no more required and hence
removed.
Documentation updated as well.

pinctrl/devicetree.c won't compile when !CONFIG_PINCTRL, since the
pinctrl headers don't declare some types when !PINCTRL. Make sure
pinctrl/Makefile only attempts to compile devicetree.c when OF &&
PINCTRL.

During pinctrl_get(), if the client device has a device tree node, look
for the common pinctrl properties there. If found, parse the referenced
device tree nodes, with the help of the pinctrl drivers, and generate
mapping table entries from them.
During pinctrl_put(), free any results of device tree parsing.

Most code assumes that the pinctrl ops are present. Validate this when
registering a pinctrl driver. Remove the one place in the code that
was checking whether one of these non-optional ops was present.

Macros in <linux/pinctrl/machine.h> call ARRAY_SIZE(), the definition of

The pinctrl_register_mappings is defined in core.c, so change the dependent
macro from CONFIG_MUX to CONFIG_PINCTRL.
The compile error message is:
drivers/pinctrl/core.c:886: error: redefinition of 'pinctrl_register_mappings'

If a process increases permissions using fcaps all of the dangerous
personality flags which are cleared for suid apps should also be cleared.
Thus programs given priviledge with fcaps will continue to have address space
randomization enabled even if the parent tried to disable it to make it

At the start of the function we assign 'a->d' to 'ap'. Then we use the
RESIZE_IF_NEEDED macro on 'a' - this may free 'a->d' and replace it
with newly allocaetd storage. In that case, we'll be operating on
freed memory further down in the function when we index into 'ap[]'.
Since we don't actually need 'ap' until after the use of the
RESIZE_IF_NEEDED macro we can just delay the assignment to it until
after we've potentially resized, thus avoiding the issue.
While I was there anyway I also changed the integer variable 'n' to be
const. It might as well be since we only assign to it once and use it
as a constant, and then the compiler will tell us if we ever assign to
it in the future.

This patch (as1542) changes the criterion ehci-hcd uses to tell when
it needs to resume the controller's root hub. A resume is needed when
a port status change is detected, obviously, but only if the root hub
is currently suspended.
Right now the driver tests whether the root hub is running, and that
is not the correct test. In particular, if the controller has died
then the root hub should not be restarted. In addition, some buggy
hardware occasionally requires the root hub to be running and
sending out SOF packets even while it is nominally supposed to be
suspended.
In the end, the test needs to be changed. Rather than checking whether
the root hub is currently running, the driver will now check whether
the root hub is currently suspended. This will yield the correct
behavior in all cases.

These devices have a number of non serial interfaces as well. Use
the existing "Direct IP" blacklist to prevent binding to interfaces
which are handled by other drivers.
We also extend the "Direct IP" blacklist with with interfaces only
seen in "QMI" mode, assuming that these devices use the same
interface numbers for serial interfaces both in "Direct IP" and in
"QMI" mode.
