Add config LIVEPATCH_DEBUG and define DEBUG if CONFIG_LIVEPATCH_DEBUG

I do not have a strong opinion but is it really worth it? Configuring
This is an alternative way, there are some similar usages:
drivers/iommu/exynos-iommu.c:
#ifdef CONFIG_EXYNOS_IOMMU_DEBUG
#define DEBUG
#endif
drivers/mtd/nand/raw/s3c2410.c:
#ifdef CONFIG_MTD_NAND_S3C2410_DEBUG
#define DEBUG
#endif
drivers/usb/storage/usb.c:
#ifdef CONFIG_USB_STORAGE_DEBUG
#define DEBUG
#endif
dynamic debug is not difficult, it is more targetted (you can enable it
just for a subset of functions in livepatch subsystem) and it can also be
done on the command line.
Yes, this is true. It is up to the maintainers to apply this patch
or not.
Thanks,
Tiezhu
