The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.
Also, notice that, dynamic memory allocations won't be affected by
this change:
"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

"Flexible array members have incomplete type, and so the sizeof operator

Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com>
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:
struct foo {
int stuff;
struct boo array[];

The jc42 driver passes I2C client's name as hwmon device name. In case
of device tree probed devices this ends up being part of the compatible
string, "jc-42.4-temp". This name contains hyphens and the hwmon core
doesn't like this:
jc42 2-0018: hwmon: 'jc-42.4-temp' is not a valid name attribute, please fix
This changes the name to "jc42" which doesn't have any illegal
characters.

The Intel Software Developers' Manual erroneously listed bit 5 of the
IA32_CORE_CAPABILITIES register as an architectural feature. It is not.
Features enumerated by IA32_CORE_CAPABILITIES are model specific and
implementation details may vary in different cpu models. Thus it is only
safe to trust features after checking the CPU model.
Icelake client and server models are known to implement the split lock
detect feature even though they don't enumerate IA32_CORE_CAPABILITIES

Resctrl assumes that all CPUs are online when the filesystem is mounted,
and that CPUs remember their CDP-enabled state over CPU hotplug.
This goes wrong when resctrl's CDP-enabled state changes while all the
CPUs in a domain are offline.
When a domain comes online, enable (or disable!) CDP to match resctrl's
current setting.
