OnePlus 9 failed boot kernel log points to this.
GrapheneOS noted this as an inherent issue on the Pixel 4 and 5 too.

What is lost?
- sanity checks and redzoning on all devices
- redzoning reportedly however causes issues on some devices such as the Pixel 3/4 and OnePlus 7
- slub sanization on 3.0, 3.4, 4.4 (except google/wahoo), xiaomi/sm6150, and oneplus/sm7250
Note: all 3.4+ devices still have page sanization

- Disable slub_debug=P for devices with INIT_ON_ALLOC/FREE_DEFAULT_ON
- Disable slub_debug=Z due to known breakage
- Disable many debug options on Linux 4.x and up
- 19.1: fixup missing manifests for vayu :\

The backported fix for CVE-2021-39713 requires CONFIG_MODULES=y
MODULES is default enabled, but some kernels are mutilated and break with it on

Drop long non-compiling devices:
- 14.1: n7100, jellypro
- 15.1: himaul, oneplus2
- 16.0: zenfone3, fugu
- 17.1: yellowstone, fugu
- 18.1: bonito, sargo
Drop in favor of 19.1:
- 17.1: bonito, sargo
- 18.1: pro1, aura, sunfish, coral, flame, bramble, redfin
(experimental, but these devices don't currently appear to have any users)

Change the property too, so it takes effect next update.
Since 16.0 lacks a toggle, this effectively disables the feature for it.
Even devices with 4GB of RAM have usability severely impacted.
Plus some other tweaks/churn

- Turns out AVB was set permissive this entire time :(
--flags 2 == VERIFICATION_DISABLED
- APEX support from GrapheneOS
- Disable vbmeta chaining like GrapheneOS
and optionally handle it like CalyxOS

This ensures init_on_alloc/free is used instead of page poisioning where available.
3.4 through 3.18 have a patch without a toggle for page sanitization.

No change to AVB devices except for enabling on more
Verity devices have the potential to regress by not booting
No change to non-verity/avb devices
Tested working on: mata, cheeseburger, fajita

Based off of patches from CalyxOS as noted in each included patch.
Tested and verified working on klte and mata 18.1

I have a sneaking suspicion that the length of some device command lines is
causing boot issues.
eg. with the recent additions, klte boots fine, but recovery doesn't, maybe
bootloader is adding more flags, exceeding a limit?

- disable disablement of PROC_PAGE_MONITOR to fix memory stats calculation
- enable slub_nomerge, similar to slab_nomerge for pre 3.18 kernels
slub_nomerge was already default enabled on many 3.10 devices via:

- Remove some changes that have been commented for a while
- Don't remove the QCOM VR repos
- Adjust the default quick tiles
- Don't force hardware layers for recents
- Only generate deltas for update_engine devices
- Cherrypick: Update WebView to 90.0.4430.66
- Adjust yylloc sed line
- Add comments to 17.1 devices explaining why they aren't removed for 18.1 yet
PRODUCT_OTA_PUBLIC_KEYS is meant to be set by a vendor tree, something
we don't use.
Override it at the source and set it explicitely as well.
This ensures that the compiled recovery.img and the one generated by
sign_target_files_apks.py includes the real public keys for verification.
11.0 signing is ignored.
This will need to be extensively tested as breakage can mean brick on locked
devices.
Although in failure cases it seems test-keys are accepted.
--
After much testing there appears to be a deeper issue with how keys
are inserted into the recovery and handled
- 18.1: disable m8, thermanager is not yet ready
- 17.1: drop cheeseburger/dumpling, it is absolutely broken
- deblobber: remove euicc + others
- deblobber: hack to remove vintf fragments
- Disable generation of unused OTA to reduce compile time
- 17.1+: Disable APEX, breaks signing, and is also useless since no Play Store.
- 18.1: Fixup signing
- Functionality tested on mako and klte
- In-place upgrade from 17.1 tested working on klte
- Compile tested on bacon and klte
- Recovery OTA key patch missing, unsure if still needed.
- Deblobber needs support for removing vintf manifest paths from vendor Android.bp
- Launcher needs more default_workspace grid variants (eg. 4x5)
