Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

uml: add back CONFIG_HZ avoid-overflows-in-kernel-timec.patch makes CONFIG_HZ necessary for a successful build. UML lacks a definition, so this patch adds one. It also changes the hard-wired definition of HZ to CONFIG_HZ. Note: this patch is a good idea even in the absence of hpa's time fixes. Cc: "H.

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 <vapier@gentoo.org> Cc: Richard Henderson <rth@twiddle.net> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Cc: Yoshinori Sato <ysato@users.sourceforge.jp> Cc: Jeff Dike <jdike@addtoit.com> Cc: Chris Zankel <chris@zankel.net> Cc: maximilian attems <max@stro.at> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> [ HZ on alpha is 1024 for historical reasons. - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 2008-05-14 23:05:42 +00:00			`#else`
