All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text.unlikely+0xe440): Section mismatch in reference from the variable L0. to the variable .init.data:acpi_masked_gpes_map
The function L0.() references
the variable __initdata acpi_masked_gpes_map.
This is often because L0. lacks a __initdata
annotation or the annotation of acpi_masked_gpes_map is wrong.

Note: the below error/warnings can be found in parent commit:
