Since v3.7 there's a link to Documentation/module-signing.txt in

Use the beam position registers, which provide at least 17 bits of data
changing at 1.79 MHz.

v2:
- Use beam position registers (which provide a faster rate but less bits)
instead of 24-bit Time-Of-Day clock in CIA B running at HSYNC.

On m68k, get_cycles() (the default implementation for random_get_entropy())
always returns zero, providing no entropy for the random driver.
Add a hook where platforms can provide their own implementation, and wire
it up in the infrastructure provided by commit

The snapshot_data structure used internally by the hibernate user
space interface code in user.c has three char fields that are used
to store boolean values. Change their data type to bool and use
true and false instead of 1 and 0, respectively, in assignments
involving t
During the creation of sched_domain, we define a pack buddy CPU for each CPU
when one is available. We want to pack at all levels where a group of CPUs can
be power gated independently from others.
On a system that can't power gate a group of CPUs independently, the flag is
set at all sched_domain
This is the 5th version of the previously named "packing small tasks" patchset.
"small" has been removed because the patchset doesn't only target small tasks
anymore.
This patchset takes advantage of the new per-task load tracking that is
available in the scheduler to pack the tasks in a minimum
Init this_load to max value instead of 0 in find_idlest_group.
If the local group is skipped because it doesn't have allowed CPUs, this_load
stays to 0, no idlest group will be returned and the selected CPU will be a
not allowed one (which will be replaced in select_fallback_rq by a random
one). W
With legacy devices converted to DT and a proper ethernet MAC
workaround, we can now remove the clk workarounds for legacy
devices. While at it, also cleanup the list of includes.

Use the activity statistics to update the list of CPUs that should be used

The cpu_power is updated for CPUs that don't participate to the packing

The ARM platforms take advantage of packing tasks on few cores if the latters
can be powergated independantly. We use DT and the cpu topology descirption
to define at which level a core can be independantly powergated to the others
and the SD_SHARE_POWERDOMAIN will be set accordingly at MC and CPU
The knob is used to set an average load threshold that will be used to trig
the inclusion/removal of CPUs in the packing effort list.
