GCC v8 defaults to enabling -fasynchronous-unwind-tables due to https://gcc.gnu.org/r259298, which results in .eh_frame section being generated. This results in additional disk usage by the build, as well as the kernel modules. Since the kernel has no use for this, this section is discarded. Add -fno-asynchronous-unwind-tables to KBUILD_CFLAGS to suppress generation of .eh_frame section. Note that our VDSOs need .eh_frame, but are not affected by this change since our VDSO code are all in assembly. Reported-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Naveen N.
