This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reads from an HPET register require a round trip to the south bridge and are almost as slow as PCI reads.

Furthermore, don't set the SETVAL bit in the config register. This wouldn't have any effect unless the timer was in period mode (which it isn't), and then the actual timer frequency would be half that of the desired one because incrementing the comparator in the interrupt handler would be done after the hardware has already incremented it itself.

| * | | [PATCH] Don't uselessly export task_struct to userspace in core dumpsEric W. Biederman2005-10-30

However there is no way for user space to know what format that information is in making it useless. I grepped the GDB 6.3 source code and NT_TASKSTRUCT while defined is not used anywhere else. So I would be surprised if anyone notices it is missing. In addition exporting kernel pointers to all the interesting kernel data structures sounds like the very definition of an information leak. I haven't a clue what someone with evil intentions could do with that information, but in any attack against the kernel it looks like this is the perfect tool for aiming that attack. So since NT_TASKSTRUCT is useless as currently defined and is potentially dangerous, let's just not export it. (akpm: Daniel Jacobowitz <dan@debian.org> "would be amazed" if anything was using NT_TASKSTRUCT). Signed-off-by: Eric W.

| * | | [PATCH] i386: use -mcpu, not -mtune, for GCCs older than 3.4Paolo 'Blaisorblade' Giarrusso2005-10-30

However -mcpu is deprecated, so use -mtune when possible. This was introduced by commit e9d4dce954a60dc23dd1d967766ca2347b780e54 of the old tree (between 2.6.10-rc3 and 2.6.10) by Linus Torvalds, to remove the use of -march, since that could trigger gcc using SSE on its own. But no attention was used about using -mcpu vs. -mtune. And btw, the old 2.6.4 code (for instance) was: cflags-$(CONFIG_MPENTIUMII) += $(call check_gcc,-march=pentium2,-march=i686) cflags-$(CONFIG_MPENTIUMIII) += $(call check_gcc,-march=pentium3,-march=i686) cflags-$(CONFIG_MPENTIUMM) += $(call check_gcc,-march=pentium3,-march=i686) cflags-$(CONFIG_MPENTIUM4) += $(call check_gcc,-march=pentium4,-march=i686) Signed-off-by: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Actually, for now many config options aren't used a lot - but that can be done later. Also, UML relies on GCC optimization for things like memcpy and such more than i386, so specifying the correct -march and -mtune should be enough. Later, we may want to correct some other stuff. For instance, since FPU context switching, for us, is done (at least partially, i.e. between our kernelspace and userspace) by the host, we may allow usage of FPU operations by GCC. This doesn't hold for kernelspace vs. kernelspace, but we don't support preemption.

| * | | [PATCH] swsusp: rework memory freeing on resumeRafael J. Wysocki2005-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch makes swsusp use the PG_nosave and PG_nosave_free flags to mark pages that should be freed in case of an error during resume. This allows us to simplify the code and to use swsusp_free() in all of the swsusp's resume error paths, which makes them actually work. Signed-off-by: Rafael J.

| * | | [PATCH] i386 mpparse: Only ignore lapic information we can't storeEric W. Biederman2005-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After staring at mpparse.c for a little longer I noticed that when we hit our limit of num_processors we are filtering out information about other processors that we can still store. This patch just reorders the code so we store everything we can. This should avoid the incorrect warning about our boot CPU not being listed by the BIOS that we are now getting in the kexec on panic case, and it should allow us to detect all apicid conflicts even when our physical number of cpus exceeds maxcpus.

Check for presence of boot cpu apic id was failing in (apic_id_registered), hence hitting BUG(). o This should not have failed because before calling setup_local_APIC(), it is ensured that even if BIOS has not reported boot cpu, then hard set the prence of it. Problem happens because of usage of hard_smp_processor_id() which is hardcoded to zero in case of non SMP kernel. In kdump case second kernel can boot on a cpu whose boot cpu id is not zero. o Using boot_cpu_physical_apicid instead to hard set the presence of boot cpu.

| * | | [PATCH] i386 kexec-on-panic: Don't shutdown the apics.Eric W. Biederman2005-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is dangerous to shutdown the apics in machine_crash_shutdown. With my previous patch to initialize apics in init_IRQ we should be able to boot a kernel without this. As long as we reinitialize the APICs we don't care what state they were in during bootup. This should make machine_crash_shutdown noticeably more reliable. Signed-off-by: Eric W.
