This patch fixes a warning:
arch/x86/entry/vdso/vdso2c.h:38:52: warning: format ʽ%luʼ expects argument of type ʽlong unsigned intʼ, but argument 4 has type ʽsize_tʼ {aka ʽunsigned intʼ} [-Wformat=]
when compiling the kernel with x32 compiler.
The reason for the warning is that in x32 mode, size_t is defined as
unsigned, not unsigned long.
