x86/mm/pti: Make local symbols static
With 'make C=2 W=1', sparse and gcc both complain: CHECK arch/x86/mm/pti.c arch/x86/mm/pti.c:84:3: warning: symbol 'pti_mode' was not declared. Should it be static? arch/x86/mm/pti.c:605:6: warning: symbol 'pti_set_kernel_image_nonglobal' was not declared. Should it be static? CC arch/x86/mm/pti.o arch/x86/mm/pti.c:605:6: warning: no previous prototype for 'pti_set_kernel_image_nonglobal' [-Wmissing-prototypes] 605 | void pti_set_kernel_image_nonglobal(void) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ pti_set_kernel_image_nonglobal() is only used locally. 'pti_mode' exists in drivers/hwtracing/intel_th/pti.c as well, but it's a completely unrelated local (static) symbol. Make both static.
