sock_cgroup_data is a struct containing an anonymous union.
sock_cgroup_set_prioidx() and sock_cgroup_set_classid() were
initializing a field inside the anonymous union as follows.
struct sock_ccgroup_data skcd_buf = { .val = VAL };
While this is fine on more recent compilers, gcc-4.4.7 triggers the
following errors.
include/linux/cgroup-defs.h: In function ‘sock_cgroup_set_prioidx’:
include/linux/cgroup-defs.h:619: error: unknown field ‘val’ specified in initializer
include/linux/cgroup-defs.h:619: warning: missing braces around initializer
include/linux/cgroup-defs.h:619: warning: (near initialization for ‘skcd_buf.<anonymous>’)
This is because .val belongs to the anonymous union nested inside the
struct but the initializer is missing the nesting. Fix it by adding

ROL on a 32 bit integer with a shift of 32 or more is undefined and the
result is arch-dependent. Avoid this by handling the trivial case of
roling by 0 correctly.
The trivial solution of checking if shift is 0 breaks gcc's detection
of this code as a ROL instruction, which is unacceptable.
This bug was reported and fixed in GCC
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57157):
The standard rotate idiom,
(x << n) | (x >> (32 - n))
is recognized by gcc (for concreteness, I discuss only the case that x
is an uint32_t here).
However, this is portable C only for n in the range 0 < n < 32. For n
== 0, we get x >> 32 which gives undefined behaviour according to the
C standard (6.5.7, Bitwise shift operators). To portably support n ==
0, one has to write the rotate as something like
(x << n) | (x >> ((-n) & 31))
And this is apparently not recognized by gcc.
Note that this is broken on older GCCs and will result in slower ROL.

When you take a metadata snapshot the btree roots for the mapping and

persist for the lifetime of the metadata snap.
The roots being incremented were those currently written in the
superblock, which could possibly be out of date if concurrent IO is
triggering new mappings, breaking of sharing, etc.

Boris reported that 'perf top' is unusable on his default 'black on
white' terminal, which uses (eye friendly) light-grey as a background
color.
The reason is that the TUI cursor for the current selection line uses
HE_COLORSET_SELECTED, and that has a default background color of
'lightgrey' - which is a common terminal background choice and thus
the colors conflict.
Use yellow as the background color instead: that should be an uncommon
terminal background, yet it's still ergonomic on both black and
white/grey terminals.
[ It would be a better solution to straight out detect color
collisions and resolve them reasonably by converting them to RGB and
calculating color space distances, but I was unable to find
proper documentation for SLtt_get_color_object() to recover the
current color scheme so I gave up ... Yellow works well enough. ]

The Alienware 17 (2015) has the same card and pin configuration of the
Alienware 15, so the same quirks must be applied.

Kabylake A0 is based on Skylake H0.
v2: Don't assume revid+7 and only load the one we are sure about.
v3: Rebase on top of latest changes.
v4: Accept cleaner solution from Jani with kbl_stepping_info
starting on H0 instead of put a hack on revid.

In checking fixes for of_irq_find_parent declaration location, I found
that of_msi_map_rid is also wrong. of_msi_map_rid is not implemented for
Sparc, so it should not be in the Sparc specific section of the header.
Move it to just depend on OF_IRQ.

Common MVEBU pinctrl driver core gets an array of controls to modify
a specific set of registers and an array of modes for each pingroup
from each of the different SoC families of MVEBU.
Some SoC families comprise different variants that differ in available
pingroups and also controls, but to ease driver development, we can
pass a variant mask to disable specific pingroups for some variants.
However, controls are limited to the true number of pinctrl groups
avaiable on a variant.
Now, when pinctrl core driver parses over above arrays, it tries to
match modes with available controls and complains about missing
controls for modes that are passed to the core but actually are not
avaiable on a variant with:
kirkwood-pinctrl f1010000.pin-controller: unknown pinctrl group 36
This warning is a false-positive and annoying, so move the warning
after we checked the variant mask for each mode setting. Also, if
there is no supported setting for this variant, do not complain at
all.
