HZ macro

[Hideo S. <sa...@de...>]

Hi Paul,

HZ macro used by tmu_timer_init() in arch/sh/kernel/timers/timer-tmu.c is defined by include/asm-sh/param.h as follows.

# ifdef CONFIG_SH_WDT
#  define HZ            1000            /* Needed for high-res WOVF */
# else
#  define HZ            100

However, I think HZ should be defined by CONFIG_HZ that is defined by Kconfig.hz.
