[PATCH] x86_64: Better ATI timer fix

The previous experiment for using apicmaintimer on ATI systems didn't
work out very well.  In particular laptops with C2/C3 support often
don't let it tick during idle, which makes it useless.  There were also
some other bugs that made the apicmaintimer often not used at all.

I tried some other experiments - running timer over RTC and some other
things but they didn't really work well neither.

I rechecked the specs now and it turns out this simple change is
actually enough to avoid the double ticks on the ATI systems.  We just
turn off IRQ 0 in the 8254 and only route it directly using the IO-APIC.

I tested it on a few ATI systems and it worked there.  In fact it worked
on all chipsets (NVidia, Intel, AMD, ATI) I tried it on.

According to the ACPI spec routing should always work through the
IO-APIC so I think it's the correct thing to do anyways (and most of the
old gunk in check_timer should be thrown away for x86-64).

But for 2.6.16 it's best to do a fairly minimal change:
 - Use the known to be working everywhere-but-ATI IRQ0 both over 8254
   and IO-APIC setup everywhere
 - Except on ATI disable IRQ0 in the 8254
 - Remove the code to select apicmaintimer on ATI chipsets
 - Add some boot options to allow to override this (just paranoia)

In 2.6.17 I hope to switch the default over to this for everybody.

[PATCH] x86_64: Move the SMP time selection earlier

This is not needed anymore because we know present CPUs early.

This fixes a couple of problems:
 - apicmaintimer didn't always work because it relied on state that was
   set up time_init_gtod too late.
 - The output for the used timer in early kernel log was misleading

ACPI is initialized very early on x86-64, before the DMI code is
initialized.  This means it would often discover a 0 year and then turn
off ACPI because it thought the BIOS was too old.  Some systems don't
boot without ACPI so this was a problem.

I have a full fix by adding new very early DMI detection, but it needs
more testing before it can be merged.  For 2.6.16 let's just turn the
check off.  It never made much sense anyways because there are no x86-64

[PATCH] page migration: Fix MPOL_INTERLEAVE behavior for migration via mbind()

migrate_pages_to() allocates a list of new pages on the intended target
node or with the intended policy and then uses the list of new pages as
targets for the migration of a list of pages out of place.

When the pages are allocated it is not clear which of the out of place
pages will be moved to the new pages.  So we cannot specify an address as
needed by alloc_page_vma().  This causes problem for MPOL_INTERLEAVE which
will currently allocate the pages on the first node of the set.  If mbind
is used with vma that has the policy of MPOL_INTERLEAVE then the
interleaving of pages may be destroyed.

This patch fixes that by generating a fake address for each alloc_page_vma
which will result is a distribution of pages as prescribed by
MPOL_INTERLEAVE.

Lee also noted that the sequence of nodes for the new pages seems to be
inverted.  So we also invert the way the lists of pages for migration are

to it, we would have to handle vertical sync & such too, which (I'd say)

Jamal Hadi Salim [Fri, 24 Feb 2006 00:18:01 +0000 (16:18 -0800)]
[NET] ethernet: Fix first packet goes out with MAC 00:00:00:00:00:00

When you turn off ARP on a netdevice then the first packet always goes
out with a dstMAC of all zeroes. This is because the first packet is
used to resolve ARP entries. Even though the ARP entry may be resolved
(I tried by setting a static ARP entry for a host i was pinging from),
it gets overwritten by virtue of having the netdevice disabling ARP.

Subsequent packets go out fine with correct dstMAC address (which may
be why people have ignored reporting this issue).

To cut the story short:

the culprit code is in net/ethernet/eth.c::eth_header()

----
        /*
         *      Anyway, the loopback-device should never use this
function...
         */

        if (dev->flags & (IFF_LOOPBACK|IFF_NOARP))
        {
                memset(eth->h_dest, 0, dev->addr_len);
                return ETH_HLEN;
        }

if(daddr)
        {
                memcpy(eth->h_dest,daddr,dev->addr_len);
                return ETH_HLEN;
        }

----

Note how the h_dest is being reset when device has IFF_NOARP.

As a note:
All devices including loopback pass a daddr. loopback in fact passes
a 0 all the time ;->
This means i can delete the check totaly or i can remove the IFF_NOARP

Alexey says:
--------------------
I think, it was me who did this crap. It was so long ago I do not remember
why it was made.

I remember some troubles with dummy device. It tried to resolve
addresses, apparently, without success and generated errors instead of
blackholing. I think the problem was eventually solved at neighbour
level.

After some thinking I suspect the deletion of this chunk could change
behaviour of some parts which do not use neighbour cache f.e. packet
socket.

I think safer approach would be to move this chunk after if (daddr).
And the possibility to remove this completely could be analyzed later.

Let the ieee1394 core select a suitable 1394 address range for sbp2's

addresses which are guaranteed to be out of the "physical range" as per
OHCI 1.1, this patch also fixes an old bug:

OHCI controllers which implement a writeable PhysicalUpperBound register
included sbp2's status FIFO in the physical range. That way sbp2 was
never notified of a succesful login and always failed after timeout.
Affected OHCI host adapters include ALi and Fujitsu controllers.

As another side effect of this patch, the status FIFO is no longer
located in a range for which OHCI chips perform "posted writes". Each
status write now requires a response subaction. But since large data
transfers involve only few status writes, there is no measurable
decrease of I/O throughput. What's more, the status FIFO is now safe
from potential host bus errors. Nevertheless, posted writes could be

[PATCH] sky2: close race on IRQ mask update.

Need to avoid race in updating IRQ mask.  This can probably be replaced
smarter use of the interrupt control registers (if/when chipset
docs are available).

[PATCH] sky2: use device iomem to access PCI config

To avoid problems with PCI config access without ACPI (or busted ACPI tables),
use the device's window into PCI config space.

I know this probably will upset the purists, but I would rather have users
than ACPI testers. It also generates less code.
