There are following warnings on unpatched code:
arch/x86/kernel/early_printk.c:198:32: warning: incorrect type in initializer (different address spaces) arch/x86/kernel/early_printk.c:198:32: expected void [noderef] <asn:2>*vaddr arch/x86/kernel/early_printk.c:198:32: got unsigned int [usertype] *<noident> arch/x86/kernel/early_printk.c:205:32: warning: incorrect type in initializer (different address spaces) arch/x86/kernel/early_printk.c:205:32: expected void [noderef] <asn:2>*vaddr arch/x86/kernel/early_printk.c:205:32: got unsigned int [usertype] *<noident>
Fix the code to make sparse silent by using proper address space.
