# arm64 puts the stub in the kernel proper, which will unnecessarily retain all
|
|
# code indefinitely unless it is annotated as __init/__initdata/__initconst etc.
|
|
# So let's apply the __init annotations at the section level, by prefixing
|
|
# the section names directly. This will ensure that even all the inline string
|
|
# literals are covered.
|
|
# The fact that the stub and the kernel proper are essentially the same binary
|
|
# also means that we need to be extra careful to make sure that the stub does
|
|
# not rely on any absolute symbol references, considering that the virtual
|
|
# kernel mapping that the linker uses is not active yet when the stub is
|
|
# executing. So build all C dependencies of the EFI stub into libstub, and do
|
|
# a verification pass to see if any absolute relocations exist in any of the
|
|
# object files.
