Subject: asm-{alpha,h8300,um,v850,xtensa}/param.h: unbreak HZ for userspace
From: Mike Frysinger <vapier@xxxxxxxxxx>
I noticed this because alpha was broken due to the recent
bdc807871d58285737. Most arches do something like this in their
asm/param.h:
#ifdef __KERNEL__
# define HZ CONFIG_HZ
#else
# define HZ 100
#endif
A few arches though (namely alpha/h8300/um/v850/xtensa) either do no set
HZ at all for !__KERNEL__, or they set it wrongly. This should bring all
arches in line by setting up HZ for userspace.
