Add missing compatible strings from 4.9/960-add-rasbperrypi-compatible.patch, using upstream names for compute modules. Add extra patch to enable the LEDs on lan78xx. Compile-tested: bcm2708, bcm2709, bcm2710 (with CONFIG_ALL_KMODS=y) Runtime-tested: bcm2708, bcm2710 Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>

Subject: [PATCH 136/454] cgroup: Disable cgroup "memory" by default
|
|
|
|
Some Raspberry Pis have limited RAM and most users won't use the
|
|
cgroup memory support so it is disabled by default. Enable with:
|
|
|
|
cgroup_enable=memory
|
|
|
|
See: https://github.com/raspberrypi/linux/issues/1950
