Subject: printk-nmi: use %zu format string for size_t
Newly added code in vprintk_nmi prints a size_t using %lu, which causes
a warning on architectures like ARM where it is defined as unsigned int:
kernel/printk/nmi.c: In function '__printk_nmi_flush':
kernel/printk/nmi.c:143:10: warning: format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'size_t {aka unsigned int}' [-Wformat=]
This uses the format string that works on all architectures.
