This patchset aims to fix a bug regards to SVM usage on native, and
also several bugs around subdevice (attached to device via auxiliary
manner) tracking and ineffective device_tlb flush.

SEV is active.
Adding `console=ttyS0` to the kernel parameters and `GRUB_TERMINAL="console
serial"`
seems to do the job without any AMD-internal patches.
Now that all of the required symbols have been exported,
and the io-pgtable code can correctly refer to the
io-pgtable init functions when their source files are built
as modules, allow the io-pgtable code to be built as a module. The
expectation is that the io-pgtable core code, along with
the
The io-pgtable source file uses the #ifdef preprocessor macro
to construct the io_pgtable_init_table structure. However,
the #ifdef macro evaluates to true if the config it is testing
is set to y. This is not ideal when the configs that the
io-pgtable code checks for can be m, so use IS_ENABLED()
The io-pgtable-arm and io-pgtable-arm-v7s source files will

structures for the io-pgtable module to use.

The goal of the Generic Kernel Image (GKI) effort is to have a common
image that works across multiple Android devices. This involves generating
a kernel image that has core features integrated into it, while SoC specific
functionality can be added to the kernel for the device as a module.
