2006-09-29[PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem)Atsushi Nemoto
Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390 timer interrupt handler with this change. Currently update_times() calculates ticks by "jiffies - wall_jiffies", but callers of do_timer() should know how many ticks to update. Passing ticks get rid of this redundant calculation. Also there are another redundancy pointed out by Martin Schwidefsky. This cleanup make a barrier added by 5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes it. As a bonus, this cleanup make wall_jiffies can be removed easily, since now wall_jiffies is always synced with jiffies. (This patch does not really remove wall_jiffies. It would be another cleanup patch) Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "Eric W.

2006-06-25[PATCH] Clean up and refactor i386 sub-architecture setupJeremy Fitzhardinge
Clean up and refactor i386 sub-architecture setup. This change moves all the code from the asm-i386/mach-*/setup_arch_pre/post.h headers, into arch/i386/mach-*/setup.c. mach-*/setup_arch_pre.h is renamed to setup_arch.h, and contains only things which should be in header files. It is purely code-motion; there should be no functional changes at all. Several functions in arch/i386/kernel/setup.c needed to be made non-static so that they're visible to the code in mach-*/setup.c. asm-i386/setup.h is used to hold the prototypes for these functions.

2006-03-23[PATCH] i386: fix uses of user_mode() vs. user_mode_vm()Jan Beulich
>commit 76381fee7e8feb4c22be636aa5d4765dbe4fbf9e >Author: Vincent Hanquez <vincent.hanquez@cl.cam.ac.uk> >Date: Thu Jun 23 00:08:46 2005 -0700 > > [PATCH] xen: x86_64: use more usermode macro > > Make use of the user_mode macro where it's possible. This is useful for Xen > because it will need only to redefine only the macro to a hypervisor call. I am of the opinion that the above changeset is incomplete, i.e. it missed converting some previous uses of user_mode to user_mode_vm. While most of them could be considered just cosmetical, at least the one in die_nmi doesn't appear to be.

2005-06-23[PATCH] Do not enforce unique IO_APIC_ID check for xAPIC systems (i386)Natalie Protasevich
This patch is per Andi's request to remove NO_IOAPIC_CHECK from genapic and use heuristics to prevent unique I/O APIC ID check for systems that don't need it. The patch disables unique I/O APIC ID check for Xeon-based and other platforms that don't use serial APIC bus for interrupt delivery. Andi stated that AMD systems don't need unique IO_APIC_IDs either.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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. Let it rip!
