I noticed this because alpha was broken due to the recent commit commit
bdc807871d ("avoid overflows in
kernel/time.c"). 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.
Without this currently perl 5.10 doesn't build on alpha:
perl.c: In function 'perl_construct':
perl.c:388: error: 'CONFIG_HZ' undeclared (first use in this function)
-> http://buildd.debian.org/fetch.cgi?pkg=perl;ver=5.10.0-10;arch=alpha;stamp=1210252894
