Unfortunately, this produces this error on sparc64 (since they use -Werror
in arch/sparc) (sparc64 defconfig build):

arch/sparc/kernel/time_64.c: In function 'time_init':
arch/sparc/kernel/time_64.c:851: error: format '%lx' expects type 'long unsigned int', but argument 2 has type 'u32'

I applied the following patch:

Subject: [PATCH] sparc: fix printk for change of variable type

The clockevent mult field became a u32.
