Convert devcoredump to use class_groups instead of class_attrs as that's

struct class needs to have a set of default groups that are added, as
adding individual attributes does not work well in the long run. So add
support for that.
Future patches will convert the existing usages of class_attrs to use
class_groups and then class_attrs will go away.

Commit 71fbd556adde ("memory-hotplug: remove redundant call of page_to_pfn")
introduced an optimization that rendered 'struct page* first_page'
useless in memory_block_action(). Compiling with W=1 gives the
following warning, fix it.
drivers/base/memory.c: In function ‘memory_block_action’:
drivers/base/memory.c:229:15: warning: variable ‘first_page’ set but not used [-Wunused-but-set-variable]
struct page *first_page;
^
This is a harmeless warning and is only being fixed to reduce the
noise with W=1 in the kernel. The call to pfn_to_page() has no side
effects and is safe to remove.

After parport starts using the device model, all pardevice drivers
should decide in their match_port callback function if they want to
attach with that particulatr port. ppdev has been converted to use the
new parport device-model code but pp_attach() tried to attach with all
the ports.
Create a new array of pointer and use that to remember the ports we
have attached. And use that information to skip attaching ports which
we have already attached.

Testing with a gcc-7 snapshot produced an internal compiler error
for this file:
drivers/tty/nozomi.c: In function 'receive_flow_control':
drivers/tty/nozomi.c:919:12: internal compiler error: in get_substring_ranges_for_loc, at input.c:1388
static int receive_flow_control(struct nozomi *dc)
I've reported this at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78569
but also noticed that the code line contains a stack overflow, as it prints
a string into a slightly shorter fixed-length 'tmp' variable.
A lot of the code here is unnecessary and can be expressed in a simpler
way, relying on the fact that removing the 'DEBUG' macro will also get
rid of all pr_debug() calls. This change should not change any of the
output but avoids both the stack overflow and the gcc crash.
The stack overflow will not happen unless a module load parameter is
also set to enable the debug messages.

During a PCI error recovery, like the ones provoked by EEH in the ppc64
platform, all IO to the device must be blocked while the recovery is
completed. Current 8250_pci implementation only suspends the port
instead of detaching it, which doesn't prevent incoming accesses like
TIOCMGET and TIOCMSET calls from reaching the device. Those end up
racing with the EEH recovery, crashing it. Similar races were also
observed when opening the device and when shutting it down during
recovery.
This patch implements a more robust IO blockage for the 8250_pci
recovery by unregistering the port at the beginning of the procedure and
re-adding it afterwards. Since the port is detached from the uart
layer, we can be sure that no request will make through to the device
during recovery. This is similar to the solution used by the JSM serial
driver.
I thank Peter Hurley <peter@hurleysoftware.com> for valuable input on
this one over one year ago.

pm_runtime_autosuspend can take synchronous or asynchronous
paths, Because we are calling pm_runtime_mark_last_busy just before
this most of the cases it takes the asynchronous way. However,
when the FW or driver resets during already running runtime suspend,
the call will result in calling to the driver's rpm callback and results
in a deadlock on device_lock.
The simplest fix is to replace pm_runtime_autosuspend with
asynchronous pm_request_autosuspend.

In order to naturally support multi-target instances on an Open-Channel
SSD, targets should own the LUNs they get blocks from and manage
provisioning internally. This is done in several steps.
Since targets own the LUNs the are instantiated on top of and manage the
free block list internally, there is no need for a LUN abstraction in
the media manager. LUNs are intrinsically managed as in the physical
layout (ch:0,lun:0, ..., ch:0,lun:n, ch:1,lun:0, ch:1,lun:n, ...,
ch:m,lun:0, ch:m,lun:n) and given to the targets based on the target
creation ioctl. This simplifies LUN management and clears the path for a
partition manager to sit directly underneath LightNVM targets.

LUNs are exclusively owned by targets implementing a block device FTL.
Doing this reservation requires at the moment a 2-way callback gennvm
<-> target. The reason behind this is that LUNs were not assumed to
always be exclusively owned by targets. However, this design decision
goes against I/O determinism QoS (two targets would mix I/O on the same
parallel unit in the device).
This patch makes LUN reservation as part of the target creation on the
media manager. This makes that LUNs are always exclusively owned by the
target instantiated on top of them. LUN stripping and/or sharing should
be implemented on the target itself or the layers on top.

The mode of operation of the TMC tracked in drvdata->mode is defined
as a local_t type. This is always checked and modified under the
drvdata->spinlock and hence we don't need local_t for it and the
unnecessary synchronisation instructions that comes with it. This
change makes the code a bit more cleaner.
Also fixes the order in which we update the drvdata->mode to
CS_MODE_DISABLED. i.e, in tmc_disable_etX_sink we change the
mode to CS_MODE_DISABLED before invoking tmc_disable_etX_hw()
which in turn depends on the mode to decide whether to dump the
trace to a buffer.

When using coresight from the perf interface sinks are specified
as part of the perf command line. As such the sink needs to be
disabled once it has been acknowledged by the coresight framework.
Otherwise the sink stays enabled, which may interfere with other
sessions.
This patch removes the sink selection check from the build path
process and make it a function on it's own. The function is
then used when operating from sysFS or perf to determine what
sink has been selected.
If operated from perf the status of the "enable_sink" flag is
reset so that concurrent session can use a different sink. When
used from sysFS the status of the flag is left untouched since
users have full control.
The implementation doesn't handle a scenario where a sink has
been enabled from sysFS and another sink is selected from the
perf command line as both modes of operation are mutually
exclusive.

In the current driver for Coresight components, two features of PTM
components are missing:
1. Branch Broadcasting (present also in ETM but called Branch Output)
2. Return Stack (only present in PTM v1.0 and PTMv1.1)
These features can be added simply to the code using `mode` field of
`etm_config` struct.
1. **Branch Broadcast** : The branch broadcast feature is present in ETM
components as well and is called Branch output. It allows to retrieve
addresses for direct branch addresses alongside the indirect branch
addresses. For example, it could be useful in cases when tracing without
source code.
2. **Return Stack** : The return stack option allows to retrieve the
return addresses of function calls. It can be useful to avoid CRA
(Code Reuse Attacks) by keeping a shadowstack.

In STM framework driver, the trace data writing loop would keep running
until it received a negative return value or the whole trace packet has
been written to STM device. So if the .packet() of STM device always
returns zero since the device is not enabled or the parameter isn't
supported, STM framework driver will stall into a dead loop.
Returning -EACCES (Permission denied) in .packet() if the device is
disabled makes more sense, and this is the same for returning -EINVAL
if the channel passed into is not supported.
