btcoex uses dm's counters to check the environment is noisy or not. If it
is clean, btcoex set more time slots to WiFi so that it can transmit as
soon as possible. That will save time, and BT will have more time slots
after WiFi traffic is complete.

Commit 7af1bb19f1d7 ("reset: add support for non-DT systems")
introduced reset control lookup mechanism for boards that still use
board files.
The routine used to register lookup entries takes the corresponding
reset_controlled_dev structure as argument.
It's been determined however that for the first user of this new
interface - davinci psc driver - it will be easier to register the
lookup entries using the reset controller device name.
This patch changes the way lookup entries are added.

The reset framework only supports device-tree. There are some platforms
however, which need to use it even in legacy, board-file based mode.
An example of such architecture is the DaVinci family of SoCs which
supports both device tree and legacy boot modes and we don't want to
introduce any regressions.
We're currently working on converting the platform from its hand-crafted
clock API to using the common clock framework. Part of the overhaul will
be representing the chip's power sleep controller's reset lines using
the reset framework.
This changeset extends the core reset code with a new reset lookup
entry structure. It contains data allowing the reset core to associate
reset lines with devices by comparing the dev_id and con_id strings.
It also provides a function allowing drivers to register lookup entries
with the framework.
The new lookup function is only called as a fallback in case the
of_node field is NULL and doesn't change anything for current users.
Tested with a dummy reset driver with several lookup entries.
An example lookup table registration from a driver can be found below:
static struct reset_control_lookup foobar_reset_lookup[] = {
RESET_LOOKUP("foo.0", "foo", 15),
RESET_LOOKUP("bar.0", NULL, 5),
};
foobar_probe()
{
...
reset_controller_add_lookup(&rcdev, foobar_reset_lookup,
ARRAY_SIZE(foobar_reset_lookup));
...

Currently the rfi-flush messages print 'Using <type> flush' for all
enabled_flush_types, but that is not necessarily true -- as now the
fallback flush is always enabled on pseries, but the fixup function
overwrites its nop/branch slot with other flush types, if available.
So, replace the 'Using <type> flush' messages with '<type> flush is
available'.
Also, print the patched flush types in the fixup function, so users
can know what is (not) being used (e.g., the slower, fallback flush,
or no flush type at all if flush is disabled via the debugfs switch).

rfi_flush_enable() includes a check to see if we're already
enabled (or disabled), and in that case does nothing.
But that means calling setup_rfi_flush() a 2nd time doesn't actually
work, which is a bit confusing.
Move that check into the debugfs code, where it really belongs.

Introduce code to support addition of blacklisted events for a
processor version. Blacklisted events are events that are known to not
count correctly on that CPU revision, and so should be prevented from
being counted so as to avoid user confusion.
A 'pointer' and 'int' variable to hold the number of events are added
to 'struct power_pmu', along with a generic function to loop through
the list to validate the given event. Generic function
'is_event_blacklisted' is called in power_pmu_event_init() to detect
and reject early.

Sampled Data Address Register (SDAR) is a 64-bit register that
contains the effective address of the storage operand of an
instruction that was being executed, possibly out-of-order, at or
around the time that the Performance Monitor alert occurred.

Current code in power_pmu_disable() does not clear the sampling
registers like Sampling Instruction Address Register (SIAR) and
Sampling Data Address Register (SDAR) after disabling the PMU. Since
these are userspace readable and could contain kernel addresses, add
code to explicitly clear the content of these registers.
Also add a "context synchronizing instruction" to enforce no further
updates to these registers as suggested by Power ISA v3.0B. From
section 9.4, on page 1108:
"If an mtspr instruction is executed that changes the value of a
Performance Monitor register other than SIAR, SDAR, and SIER, the
change is not guaranteed to have taken effect until after a
subsequent context synchronizing instruction has been executed (see
Chapter 11. "Synchronization Requirements for Context Alterations"
on page 1133)."

On POWER9, since commit cc3d2940133d ("powerpc/64: Enable use of radix
MMU under hypervisor on POWER9", 2017-01-30), we set both the radix and
HPT bits in the client-architecture-support (CAS) vector, which tells
the hypervisor that we can do either radix or HPT. According to PAPR,
if we use this combination we are promising to do a H_REGISTER_PROC_TBL
hcall later on to let the hypervisor know whether we are doing radix
or HPT. We currently do this call if we are doing radix but not if
we are doing HPT. If the hypervisor is able to support both radix
and HPT guests, it would be entitled to defer allocation of the HPT
until the H_REGISTER_PROC_TBL call, and to fail any attempts to create
HPTEs until the H_REGISTER_PROC_TBL call. Thus we need to do a
H_REGISTER_PROC_TBL call when we are doing HPT; otherwise we may
crash at boot time.
This adds the code to call H_REGISTER_PROC_TBL in this case, before
we attempt to create any HPT entries using H_ENTER.

commit dd9f31c7a3887950cbd0d49eb9d43f7a1518a356
Author: Imre Deak <imre.deak@intel.com>

drm/i915/gen9+: Set same power state before hibernation image
save/restore
during hibernation/suspend the power domain functionality got disabled,
after which resume could leave it incorrectly disabled if the ACPI
target state was S0 during suspend and i915 was not loaded by the loader
kernel.
This was caused by not considering if we resumed from hibernation as the
condition for power domains reiniting.
Fix this by simply tracking if we suspended power domains during system
suspend and reinit power domains accordingly during resume. This will
result in reiniting power domains always when resuming from hibernation,
regardless of the platform and whether or not i915 is loaded by the
loader kernel.
The reason we didn't catch this earlier is that the enabled/disabled
state of power domains during PMSG_FREEZE/PMSG_QUIESCE is platform
and kernel config dependent: on my SKL the target state is S4
during PMSG_FREEZE and (with the driver loaded in the loader kernel)
S0 during PMSG_QUIESCE. On the reporter's machine it's S0 during
PMSG_FREEZE but (contrary to this) power domains are not initialized
during PMSG_QUIESCE since i915 is not loaded in the loader kernel, or
it's loaded but without the DMC firmware being available.

We were relying on the uncached reads when processing the CSB to provide
ourselves with the serialisation with the interrupt handler (so we could
detect new interrupts in the middle of processing the old one). However,
in commit 767a983ab255 ("drm/i915/execlists: Read the context-status HEAD
from the HWSP") those uncached reads were eliminated (on one path at
least) and along with them our serialisation. The result is that we
would very rarely miss notification of a new interrupt and leave a
context-switch unprocessed, hanging the GPU.

If bios sets up an MST output and hardware state readout code sees this is
an SST configuration, when disabling the encoder we end up calling
->post_disable_dp() hook instead of the MST version. Consequently, we write
to the DP_SET_POWER dpcd to set it D3 state. Further along when we try
enable the encoder in MST mode, POWER_UP_PHY transaction fails to power up
the MST hub. This results in continuous link training failures which keep
the system busy delaying boot. We could identify bios MST boot discrepancy
and handle it accordingly but a simple way to solve this is to write to the
DP_SET_POWER dpcd for MST too.

The use of stack Variable Length Arrays needs to be avoided, as they
can be a vector for stack exhaustion, which can be both a runtime bug
(kernel Oops) or a security flaw (overwriting memory beyond the
stack). Also, in general, as code evolves it is easy to lose track of
how big a VLA can get. Thus, we can end up having runtime failures
that are hard to debug. As part of the directive[1] to remove all VLAs
from the kernel, and build with -Wvla.
Currently rsi code uses a VLA based on a function argument to
`rsi_sdio_load_data_master_write()`. The function call chain is
Both these functions
rsi_sdio_reinit_device()
rsi_probe()
start the call chain:
rsi_hal_device_init()
rsi_load_fw()
auto_fw_upgrade()
ping_pong_write()
rsi_sdio_load_data_master_write()
[Without familiarity with the code] it appears that none of the 4 locks
mutex
rx_mutex
tx_mutex
tx_bus_mutex
are held when `rsi_sdio_load_data_master_write()` is called. It is therefore
safe to use kmalloc with GFP_KERNEL.
We can avoid using the VLA by using `kmalloc()` and free'ing the memory on all
exit paths.
Change buffer from 'u8 array' to 'u8 *'. Call `kmalloc()` to allocate memory for
the buffer. Using goto statement to call `kfree()` on all return paths.
It can be expected that this patch will result in a small increase in overhead
due to the use of `kmalloc()` however this code is only called on initialization
(and re-initialization) so this overhead should not degrade performance.

This reverts commit 4e017f1419397473cf3db6e9fa020013998b1aa4.
As explained by Rob Herring:
"This "fix" is wrong. Memory controllers with chip selects should have
the chip select in the unit-address. The correct fix here is you should drop
"simple-bus"."

Fixes a segfault occurring when e.g. <TAB> is pressed multiple times in the
ncurses tmon application. The segfault is caused by incrementing
cur_thermal_record in the main function without checking if it's value reached
NR_THERMAL_RECORD immediately. Since the boundary check only occurred in
update_thermal_data a race condition existed, which lead to an attempted read
beyond the last element of the trec array.
The fix was implemented by moving the cur_thermal_record incrementation to the
update_thermal_data function using a temporary variable on which the boundary
condition is checked before updating cur_thread_record, so that the variable is
never incremented beyond the trec array's boundary.
It seems the segfault does not occur on every machine: On a HP EliteBook G4 the
segfault happens, while it does not happen on a Thinkpad T540p.

The linkage between the bluetooth driver and the wireless
driver is not defined properly, leading to build problems
such as:
warning: (BT_HCIRSI) selects RSI_COEX which has unmet direct dependencies (NETDEVICES && WLAN && WLAN_VENDOR_RSI && BT_HCIRSI && RSI_91X)
drivers/net/wireless/rsi/rsi_91x_main.o: In function `rsi_read_pkt':
(.text+0x205): undefined reference to `rsi_bt_ops'
As the dependency is actually the reverse (RSI_91X uses
the BT_RSI driver, not the other way round), this changes
the dependency to match, and enables the bluetooth driver
from the RSI_COEX symbol.

This allows using this parser with any flash driver that takes care of
setting of_node (using mtd_set_of_node helper) correctly. Up to now
support for "fixed-partitions" DT compatibility string was working only
with flash drivers that were specifying "ofpart" (manually or by letting
mtd use the default set of parsers).
This matches existing bindings documentation.

Type "ofpart" means that OF should be used to get partitioning info and
this driver supports "fixed-partitions" binding only. Renaming it should
lead to less confusion especially when parsers for new compatibility
strings start to appear.

In order to properly support compatibility strings as described in the
bindings/mtd/partition.txt "ofpart" type should be treated as an
indication for looking into OF. MTD should check "compatible" property
and search for a matching parser rather than blindly trying the one
supporting "fixed-partitions".
It also means that existing "fixed-partitions" parser should get renamed
to use a more meaningful name.
This commit achievies that aim by introducing a new mtd_part_of_parse().
It works by looking for a matching parser for every string in the
"compatibility" property (starting with the most specific one).
Please note that driver-specified parsers still take a precedence. It's
assumed that driver providing a parser type has a good reason for that
(e.g. having platform data with device-specific info). Also doing
otherwise could break existing setups. The same applies to using default
parsers (including "cmdlinepart") as some overwrite DT data with cmdline
argument.
Partition parsers can now provide an of_match_table to enable
flash<-->parser matching via device tree as documented in the
mtd/partition.txt.
This support is currently limited to built-in parsers as it uses
request_module() and friends. This should be sufficient for most cases
though as compiling parsers as modules isn't a common choice.
