Put the current logic in bnxt_open() to re-enable SRIOV after detecting
firmware reset into a new function bnxt_reenable_sriov(). This call
needs to be invoked in the firmware reset path also in the next patch.

It's found that stmmac_xmit() and stmmac_resume() sometimes might
run concurrently, possibly resulting in a race condition between
mod_timer() and setup_timer(), being called by stmmac_xmit() and
stmmac_resume() respectively.
Since the resume() runs setup_timer() every time, it'd be safer to
have del_timer_sync() in the suspend() as the counterpart.

Pull clk updates from Stephen Boyd:
"There are a few changes to the core framework this time around, in
addition to the normal collection of driver updates to support new
SoCs, fix incorrect data, and convert various drivers to clk_hw based
APIs.
In the core, we allow clk_ops::init() to return an error code now so
that we can fail clk registration if the callback does something like
fail to allocate memory. We also add a new "terminate" clk_op so that
things done in clk_ops::init() can be undone, e.g. free memory. We
also spit out a warning now when critical clks fail to enable and we
support changing clk rates and enable/disable state through debugfs
when developers compile the kernel themselves.
On the driver front, we get support for what seems like a lot of
Qualcomm and NXP SoCs given that those vendors dominate the diffstat.
There are a couple new drivers for Xilinx and Amlogic SoCs too. The
updates are all small things like fixing the way glitch free muxes
switch parents, avoiding div-by-zero problems, or fixing data like
parent names. See the updates section below for more details.
Finally, the "basic" clk types have been converted to support
specifying parents with clk_hw pointers. This work includes an
overhaul of the fixed-rate clk type to be more modern by using clk_hw
APIs.
Core:
- Let clk_ops::init() return an error code
- Add a clk_ops::terminate() callback to undo clk_ops::init()
- Warn about critical clks that fail to enable or prepare
- Support dangerous debugfs actions on clks with dead code
New Drivers:
- Support for Xilinx Versal platform clks
- Display clk controller on qcom sc7180
- Video clk controller on qcom sc7180

The DFS frequency table logic overwrites 'cfg' while detecting the
parent clk and then later on in clk_rcg2_dfs_populate_freq() we use that
same variable to figure out the mode of the clk, either MND or not. Add
a new variable to hold the parent clk bit so that 'cfg' is left
untouched for use later.
This fixes problems in detecting the supported frequencies for any clks
in DFS mode.

Fix a kernel panic by checking that the sta is not NULL.
This could happen during a reconfig flow, as mac80211 moves the sta
between all the states without really checking if the previous state was
successfully set. So, if for some reason we failed to add back the
station, subsequent calls to sta_state() callback will be done when the
station is NULL. This would result in a following panic:

When a FTM request is aborted, the driver sends the abort command to
the fw and waits for a response. When the response arrives, the driver
calls cfg80211_pmsr_complete() for that request.
However, cfg80211 frees the requested data immediately after sending
the abort command, so this may lead to use after free.
Fix it by clearing the request data in the driver when the abort
command arrives and ignoring the fw notification that will come
afterwards.

Till now, the driver asked the fw for a DTS measurement in automatic
mode. This triggered a flow in which the fw actively measured the
temperature. This is not needed anymore, as the fw performs
measurements by itself, without the driver triggering them, and the
current cadence in which the fw performs such measurements is
sufficient.
In addition, in some time-sensitive scenarios, in which the driver asks
the fw for an active measurement twice in a short time (<100ms), the fw
asserts with code 0x20100801.
Change the DTS measurement to _WITHOUT_MEASURE instead, so the fw will
respond with the last measurement it has performed.

The IGTK keys are only removed by mac80211 after it has already
removed the AP station. This causes the driver to throw an error
because mac80211 is trying to remove the IGTK when the station doesn't
exist anymore.
The firmware is aware that the station has been removed and can deal
with it the next time we try to add an IGTK for a station, so we
shouldn't try to remove the key if the station ID is
IWL_MVM_INVALID_STA. Do this by removing the check for mvm_sta before
calling iwl_mvm_send_sta_igtk() and check return from that function
gracefully if the station ID is invalid.

There is no real need to have a pointer to the tagset in
struct nvme_queue, as we only need it in a single place, and that place
can derive the used tagset from the device and qid trivially. This
fixes a problem with stale pointer exposure when tagsets are reset,
and also shrinks the nvme_queue structure. It also matches what most
other transports have done since day 1.

In old days, the "host-progs" syntax was used for specifying host
programs. It was renamed to the current "hostprogs-y" in 2004.
It is typically useful in scripts/Makefile because it allows Kbuild to
selectively compile host programs based on the kernel configuration.
This commit renames like follows:
always -> always-y
hostprogs-y -> hostprogs
So, scripts/Makefile will look like this:
always-$(CONFIG_BUILD_BIN2C) += ...
always-$(CONFIG_KALLSYMS) += ...
...
hostprogs := $(always-y) $(always-m)
I think this makes more sense because a host program is always a host
program, irrespective of the kernel configuration. We want to specify
which ones to compile by CONFIG options, so always-y will be handier.
The "always", "hostprogs-y", "hostprogs-m" will be kept for backward
compatibility for a while.

The 'cros_ec' core driver is the common interface for the cros_ec
transport drivers to do the shared operations to register, unregister,
suspend, resume and handle_event. The interface is provided by including
the header 'include/linux/platform_data/cros_ec_proto.h', however, instead
of have the implementation of these functions in cros_ec_proto.c, it is in
'cros_ec.c', which is a different kernel module. Apart from being a bad
practice, this can induce confusions allowing the users of the cros_ec
protocol to call these functions.
The register, unregister, suspend, resume and handle_event functions
*should* only be called by the different transport drivers (i2c, spi, lpc,
etc.), so make this a bit less confusing by moving these functions from
the public in-kernel space to a private include in platform/chrome, and
then, the interface for cros_ec module and for the cros_ec_proto module is
clean.

Commit 8f18eca9ebc5 ("HID: ite: Add USB id match for Acer SW5-012 keyboard
dock") added the USB id for the Acer SW5-012's keyboard dock to the
hid-ite driver to fix the rfkill driver not working.
Most keyboard docks with an ITE 8595 keyboard/touchpad controller have the
"Wireless Radio Control" bits which need the special hid-ite driver on the
second USB interface (the mouse interface) and their touchpad only supports
mouse emulation, so using generic hid-input handling for anything but
the "Wireless Radio Control" bits is fine. On these devices we simply bind
to all USB interfaces.
But unlike other ITE8595 using keyboard docks, the Acer Aspire Switch 10
(SW5-012)'s touchpad not only does mouse emulation it also supports
HID-multitouch and all the keys including the "Wireless Radio Control"
bits have been moved to the first USB interface (the keyboard intf).
So we need hid-ite to handle the first (keyboard) USB interface and have
it NOT bind to the second (mouse) USB interface so that that can be
handled by hid-multitouch.c and we get proper multi-touch support.
This commit changes the hid_device_id for the SW5-012 keyboard dock to
only match on hid devices from the HID_GROUP_GENERIC group, this way
hid-ite will not bind the the mouse/multi-touch interface which has
HID_GROUP_MULTITOUCH_WIN_8 as group.
This fixes the regression to mouse-emulation mode introduced by adding
the keyboard dock USB id.

By now, bmap() will either return the physical block number related to
the requested file offset or 0 in case of error or the requested offset
maps into a hole.
This patch makes the needed changes to enable bmap() to proper return
errors, using the return value as an error return, and now, a pointer
must be passed to bmap() to be filled with the mapped physical block.
It will change the behavior of bmap() on return:
- negative value in case of error
- zero on success or map fell into a hole
In case of a hole, the *block will be zero too
Since this is a prep patch, by now, the only error return is -EINVAL if
->bmap doesn't exist.

The OR routing logic in NVKM does not expect to receive supervisor
interrupts until the DD has provided consistent information on the
ORs it's using and the EVO/NVD assembly state to match.
The combination of changing window ownership + core channel update
during display init triggered a situation where we'd disconnect an
OR from the pad it was meant to still be driving on some systems.

For various complicated reasons, we need to avoid sending a core update
method during display init. Something, which we've been required to do
on GV100 and up because we've been assigning windows to heads there and
the HW is rather picky about when that's allowed.
This moves window assignment into the modesetting path at a point where
it's much safer to send our first update methods to NVDisplay.

In certain system configurations it may not be desirable to use some
C-states assumed to be available by intel_idle and the driver needs
to be prevented from using them even before the cpuidle sysfs
interface becomes accessible to user space. Currently, the only way
to achieve that is by setting the 'max_cstate' module parameter to a
value lower than the index of the shallowest of the C-states in
question, but that may be overly intrusive, because it effectively
makes all of the idle states deeper than the 'max_cstate' one go
away (and the C-state to avoid may be in the middle of the range
normally regarded as available).
To allow that limitation to be overcome, introduce a new module
parameter called 'states_off' to represent a list of idle states to
be disabled by default in the form of a bitmask and update the
documentation to cover it.

For diagnostics, it is generally useful to be able to make intel_idle
take the system's ACPI tables into consideration even if that is not
required for the processor model in there, so introduce a new module
parameter, 'use_acpi', to make that happen and update the documentation
to cover it.
While at it, fix the 'no_acpi' module parameter name in the
documentation.

both its_mapc_cmd.col and its_invall_cmd.col sit at the same offset of

422 static void btree_flush_write(struct cache_set *c)

432 spin_lock(&c->journal.flush_write_lock);
433 if (c->journal.btree_flushing) {
434 spin_unlock(&c->journal.flush_write_lock);
435 return;
436 }

As the warning information indicates, local varaible ref_nr in unsigned
int type is wrong, which does not matche atomic_read() and the "<= 0"
checking.
This patch fixes the above error by defining local variable ref_nr as
int type.

In year 2007 high performance SSD was still expensive, in order to
save more space for real workload or meta data, the readahead I/Os
for non-meta data was bypassed and not cached on SSD.
In now days, SSD price drops a lot and people can find larger size
SSD with more comfortable price. It is unncessary to alway bypass
normal readahead I/Os to save SSD space for now.
This patch adds options for readahead data cache policies via sysfs
file /sys/block/bcache<N>/readahead_cache_policy, the options are,
- "all": cache all readahead data I/Os.
- "meta-only": only cache meta data, and bypass other regular I/Os.
If users want to make bcache continue to only cache readahead request
for metadata and bypass regular data readahead, please set "meta-only"
to this sysfs file. By default, bcache will back to cache all read-
ahead requests now.

In bset.h, macro bset_bkey_last() is defined as,
bkey_idx((struct bkey *) (i)->d, (i)->keys)
Parameter i can be variable type of data structure, the macro always
works once the type of struct i has member 'd' and 'keys'.
bset_bkey_last() is also used in macro csum_set() to calculate the
checksum of a on-disk data structure. When csum_set() is used to
calculate checksum of on-disk bcache super block, the parameter 'i'
data type is struct cache_sb_disk. Inside struct cache_sb_disk (also in
struct cache_sb) the member keys is __u16 type. But bkey_idx() expects
unsigned int (a 32bit width), so there is problem when sending
parameters via stack to call bkey_idx().
Sparse tool from Intel 0day kbuild system reports this incompatible
problem. bkey_idx() is part of user space API, so the simplest fix is
to cast the (i)->keys to unsigned int type in macro bset_bkey_last().

Commit 83ff9318c44ba ("bcache: not use hard coded memset size in

understand by removing the hard coded number with following change,
void bch_cache_accounting_clear(...)
{
memset(&acc->total.cache_hits,
0,
- sizeof(unsigned long) * 7);
+ sizeof(struct cache_stats));
}
Unfortunately the change was wrong (it also tells us the original code
was not easy to correctly understand). The hard coded number 7 is used
because in struct cache_stats,
15 struct cache_stats {
16 struct kobject kobj;
17
18 unsigned long cache_hits;
19 unsigned long cache_misses;
20 unsigned long cache_bypass_hits;
21 unsigned long cache_bypass_misses;
22 unsigned long cache_readaheads;
23 unsigned long cache_miss_collisions;
24 unsigned long sectors_bypassed;
25
26 unsigned int rescale;
27 };
only members in LINE 18-24 want to be set to 0. It is wrong to use
'sizeof(struct cache_stats)' to replace 'sizeof(unsigned long) * 7), the
memory objects behind acc->total is staled by this change.
