From b7cffc1f29c1bc729bc50c863c87f93f9b70994b Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Wed, 14 May 2008 16:05:42 -0700 Subject: asm-{alpha,h8300,um,v850,xtensa}/param.h: unbreak HZ for userspace I noticed this because alpha was broken due to the recent commit commit bdc807871d58285737d50dc6163d0feb72cb0dc2 ("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 Signed-off-by: Mike Frysinger Cc: Richard Henderson Cc: Ivan Kokshaysky Cc: Yoshinori Sato Cc: Jeff Dike Cc: Chris Zankel Cc: maximilian attems Signed-off-by: Andrew Morton [ HZ on alpha is 1024 for historical reasons. - Linus ] Signed-off-by: Linus Torvalds --- include/asm-um/param.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/asm-um') diff --git a/include/asm-um/param.h b/include/asm-um/param.h index 4cd4a226f8c1..e44f4e60d16d 100644 --- a/include/asm-um/param.h +++ b/include/asm-um/param.h @@ -13,6 +13,8 @@ #define HZ CONFIG_HZ #define USER_HZ 100 /* .. some user interfaces are in "ticks" */ #define CLOCKS_PER_SEC (USER_HZ) /* frequency at which times() counts */ +#else +#define HZ 100 #endif #endif -- cgit v1.2.3
