Unfortunately, it's not just checkpatch. This patch also causes a
large number of test suite regressions. In particular it looks like
kgdbwait does not work with this patch applied.
The problem occurs on multiple architectures all with
close-to-defconfig kernels. However to share one specific
failure, x86_64_defconfig plus the following is not bootable:
../scripts/config --enable DEBUG_INFO --enable DEBUG_FS \
--enable KALLSYMS_ALL --enable MAGIC_SYSRQ --enable KGDB \
--enable KGDB_TESTS --enable KGDB_KDB --enable KDB_KEYBOARD \
--enable LKDTM
Try:
qemu-system-x86_64 \
-enable-kvm -m 1G -smp 2 -nographic
-kernel arch/x86/boot/bzImage \
-append "console=ttyS0,115200 kgdboc=ttyS0 kgdbwait"
