android/gki_protected_modules serves as a running
list of protected GKI modules. This list is being
used as an input to generate list of protected
GKI modules exports at android/abi_gki_protected_exports
All GKI modules are protected except zram.ko & zsmalloc.ko
as baseline in this list.

Implement support for protecting the exported symbols of
protected GKI modules.
Only signed GKI modules are permitted to export symbols
listed in the android/abi_gki_protected_exports file.
Attempting to export these symbols from an unsigned module
will result in the module failing to load, with a
'Permission denied' error message.

Change f3a376d35d83 ("Revert "Add CFG80211 and MAC80211 as modules"")
Removed cfg80211.ko and mac80211.ko as vendor modules to use GKI
versions for virtual_device arm64 builds.
Remove symbols required for these modules from the symbol list;
so they stay protected for everyone until there is a proper case
for overriding these modules is required.

Remove zram & zsmalloc symbols from abi_gki_aarch64.
This makes these modules as protected until some partner
adds these symbols in their symbol list to override them.
This also cleans up the generic symbol list as per the

to the KMIs until they are being override by the partners.

android14-5.15 is broken on Dragonboard 845c because of recently added symbols.
So updated the symbols list by running:
BUILD_CONFIG=common/build.config.db845c build/build_abi.sh -s
And updated the abi_gki_aarch64 ABI by running:
"BUILD_CONFIG=common/build.config.gki.aarch64 \
ABI_DEFINITION=abi_gki_aarch64.xml build/build_abi.sh \
--update --print-report"
Due to no published ABI reference with android14-5.15, the leaf report is not
printed; the symbol causing the problem seems to be:
msm: Unknown symbol drm_bridge_detect (err -2)

The following symbols no longer exist after reverting the out-of-tree
pKVM patches inherited from android13-5.15:
- pkvm_iommu_finalize
- pkvm_iommu_resume
- pkvm_iommu_s2mpu_register
- pkvm_iommu_suspend
- pkvm_iommu_sysmmu_sync_register
Additionally, mem_encrypt_active does not make sense outside of a pKVM
guest (as it will always return 0).
Remove references to these symbols from the symbol lists so that we can
get presubmit working again before re-introducing the symbols in a newer
version of the pKVM series.
