Get kernel working on Marshmallow

[gsstudios]

Development paused

While we're currently stuck on MM support on dori kernel, so I'm giving gustavo kernel a go. This is mainly because we know that selinux is working on this kernel so I'll see if we can use this to my advantage :)

Current status: Stuck on ROM boot animation

Things to do:

• [x] Merge old CM13 ramdisk
• [x] Merge CM13 selinux changes
• [x] Test out changes
• [x] Try to merge some other changes and fixes from CM
• [x] Merge June CM13 Ramdisk
• [x] Find out why screen goes blank after going past samsung boot logo
• [ ] Get past ROM bootloop

ETA: Unknown

As long as we get a bootable kernel, this is only for testing purposes. I will use this to help me with dori MM development.

[gsstudios]

This is a very quick merge of all of the required CM13 changes. Anything could have been messed up in the merge so I will be testing shortly.

[gsstudios]

As suspected, it can go past samsung logo but gives black screen. Phone reboots and goes back into recovery.

[gsstudios]

Maybe I should try mmc_block_minors with original value to see if this is a bad change.

Edit: I should have waited for an updated ramdisk, looks like I'll have to do that later :)

[gsstudios]

Ramdisk was updated in this commit: 4ba60a3591b4412d63cc277abd4ff39dfb708f93

Some more changes were merged from CM to keep the kernel somewhat closer to mainline.

[gsstudios]

I might make selinux permissive in the kernel boot parameter and see if this helps with things.

[gsstudios]

Kernel now shows bootlogo with selinux permissive!!!

what error message is given by logcat launched from adb in load time?

[gsstudios]

I have given logs here:

It seems that selinux is working and vold seems to be happy. Now it's time to look elsewhere :)
