#     kbuild: remove EXPERT and !COMPILE_TEST guarding from TRIM_UNUSED_KSYMS
#     
#     This reverts the following two commits:
#     
#       - a555bdd0c58c ("Kbuild: enable TRIM_UNUSED_KSYMS again, with some guarding")
#       - 5cf0fd591f2e ("Kbuild: disable TRIM_UNUSED_KSYMS option")
#     
#     Commit 5e9e95cc9148 ("kbuild: implement CONFIG_TRIM_UNUSED_KSYMS without
#     recursion") solved the build time issue.
