[PATCH] powerpc/iseries: Fix double phys_to_abs bug in htab_bolt_mapping
Before the merge I updated create_pte_mapping() to work for iSeries, by
calling iSeries_hpte_bolt_or_insert. (
4c55130b2aa93370f1bf52d2304394e91cf8ee39)
Later we changed iSeries_hpte_insert to cope with the bolting case, and called
that instead from create_pte_mapping() (which was renamed to htab_bolt_mapping)
(
3c726f8dee6f55e96475574e9f645327e461884c).
Unfortunately that change introduced a subtle bug, where we pass an absolute
address to iSeries_hpte_insert() where it expects a physical address. This
leads to us calling phys_to_abs() twice on the physical address, which is
seriously bogus.
This only causes a problem if the absolute address from the first translation
can be looked up again in the chunk_map, which depends on the size and layout
of memory. I've seen it fail on one box, but not others.
The minimal fix is to pass the physical address to iSeries_hpte_insert(). For
2.6.17 we should make phys_to_abs() BUG if we try to double-translate an
address.

Previously, the PCI Hotplug module had been changed to use the new

5fa80fcdca9d20d30c9ecec30d4dbff4ed93a5c6
When rpaphp_pci_config_slot() was moved from the rpaphp driver to the

stuff was dropped. This patch restores it.

[IPSEC]: Kill post_input hook and do NAT-T in esp_input directly
The only reason post_input exists at all is that it gives us the
potential to adjust the checksums incrementally in future which
we ought to do.
However, after thinking about it for a bit we can adjust the
checksums without using this post_input stuff at all. The crucial
point is that only the inner-most NAT-T SA needs to be considered
when adjusting checksums. What's more, the checksum adjustment
comes down to a single u32 due to the linearity of IP checksums.
We just happen to have a spare u32 lying around in our skb structure :)
When ip_summed is set to CHECKSUM_NONE on input, the value of skb->csum
is currently unused. All we have to do is to make that the checksum
adjustment and voila, there goes all the post_input and decap structures!
I've left in the decap data structures for now since it's intricately
woven into the sec_path stuff. We can kill them later too.

Further investigation shows that the problem was introduced during
Alan's "TTY layer buffering revamp" patch, the amount of data to be
copied being reduced after buffer allocation. Moving the count fixup
around solves the problem.

Commit
9c869edac591977314323a4eaad5f7633fca684f broke voyager again
rather subtly because it already had its own topology exporting
functions, so now each CPU gets registered twice.
I think we can actually use the generic ones, so I don't propose
reverting it. The attached should eliminate the voyager topology
functions in favour of the generic ones.

[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.

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.

ACPI is initialized very early on x86-64, before the DMI code is

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

[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
build.

[PATCH] vgacon: no vertical resizing on EGA
EGA boards suck: they mostly have write-only registers. This is
particularly problematic for the overflow register: for being able to write
to it, we would have to handle vertical sync & such too, which (I'd say)
would potentially break a lot of configurations. Instead, just disabling
vertical resize for EGA boards is just nice enough (horizontal resize still
works).
