Some metric groups have metric constraints. A metric group can be
scheduled as a group only when some constraints are applied. For
example, Page_Walks_Utilization has a metric constraint,
"NO_NMI_WATCHDOG".
When NMI watchdog is disabled, the metric group can be scheduled as a
group. Otherwise, splitting the metric group into standalone metrics.
Add a new function, metricgroup__has_constraint(), to check whether all
constraints are applied. If not, splitting the metric group into
standalone metrics.
Currently, only one constraint, "NO_NMI_WATCHDOG", is checked. Print a
warning for the metric group with the constraint, when NMI WATCHDOG is
enabled.

examination. Factor out sysctl__nmi_watchdog_enabled() to retrieve the
NMI watchdog status.
Users may count more than one metric group each time. If so, the NMI
watchdog status may be retrieved several times. To reduce the overhead,
cache the NMI watchdog status.

Each purge request is sent by driver after master core is powered up and
unresetted but before it is unstalled. On unstall, ROM begins processing
the request and initializing environment for FW load. Host should await
ROM's ack before moving forward. Without doing so, ROM init poll may
start too early and false timeouts can occur.

Skylake driver does the controller init operation twice:
- first during probe (only to stop it just before scheduling probe_work)
- and during said probe_work where the actual correct sequence is
executed
To properly complete boot sequence when iDisp codec is present, bus
initialization has to be called only after _i915_init() finishes.
With additional _reset_list preceding _i915_init(), iDisp codec never
gets the chance to enumerate on the link. Remove the superfluous

The currently listed dotclock disagrees with the currently
listed vrefresh rate. Change the dotclock to match the vrefresh.
There are two variants of the COM37H3M panel.
The older one's COM37H3M05DTC data sheet specifies:
MIN TYP MAX
CLK frequency fCLK -- 22.4 26.3 MHz (in VGA mode)
VSYNC Frequency fVSYNC 54 60 66 Hz
VSYNC cycle time tv -- 650 -- H
HSYNC frequency fHSYNC -- 39.3 -- kHz
HSYNC cycle time th -- 570 -- CLK
The newer one's COM37H3M99DTC data sheet says:
MIN TYP MAX
CLK frequency fCLK 18 19.8 27 MHz
VSYNC Frequency fVSYNC 54 60 66 Hz
VSYNC cycle time tv 646 650 700 H
HSYNC frequency fHSYNC -- 39.0 50.0 kHz
HSYNC cycle time th 504 508 630 CLK
So we choose a parameter set that lies within the specs
of both variants. We start at .vrefresh = 60,
choose .htotal = 570 and .vtotal = 650 and end up
in a clock of 22.230 MHz.

Until now the flex parser capability was used in ib_query_device() to
indicate tunnel_offloads_caps support for mpls_over_gre/mpls_over_udp.
Newer devices and firmware will have configurations with the flexparser
but without mpls support.
Testing for the flex parser capability was a mistake, the tunnel_stateless
capability was intended for detecting mpls and was introduced at the same
time as the flex parser capability.
Otherwise userspace will be incorrectly informed that a future device
supports MPLS when it does not.

btf_enum_check_member() checked if the size of "enum" as a struct
member exceeded struct_size or not. Then, the function compared it
with the size of "int". Although the size of "enum" is 4-byte by
default (i.e., equivalent to "int"), the packing feature enables
us to reduce it, as illustrated by the following example:
struct A {
char m;
enum { E0, E1 } __attribute__((packed)) n;
};
With such a setup above, the bpf loader gave an error attempting
to load it:

E1 val=1

libtraceevent (used by perf and trace-cmd) failed to parse the
xhci_urb_dequeue trace event. This is because the user space trace
event format parsing is not a full C compiler. It can handle some basic
logic, but is not meant to be able to handle everything C can do.
In cases where a trace event field needs to be converted from a number
to a string, there's the __print_symbolic() macro that should be used:
See samples/trace_events/trace-events-sample.h
Some xhci trace events open coded the __print_symbolic() causing the
user spaces tools to fail to parse it. This has to be replaced with
__print_symbolic() instead.

In f2fs_vm_page_mkwrite(), if inode is compress one, and current mmapped
page locates in compressed cluster, we have to call f2fs_get_dnode_of_data()
to get its physical block address before f2fs_wait_on_block_writeback().

inode.i_blocks counts based on 512byte sector, we need to convert
to 4kb sized block count before comparing to i_compr_blocks.
In addition, add to print message when sanity check on inode
compression configs failed.
