[PATCH] uml: fix signal frame alignment
Use the same signal frame alignment calculations as the underlying

subtracting 8 * sizeof(struct rt_sigframe) rather than 8 bytes.
UML/i386 might have been OK, but I changed the calculation to match

Consider, if we run the loop and we get an error
the following happens:
1) attempt of ifb_init_one(i) fails, therefore we should
not try to "ifb_free_one()" on "i" since it failed
2) the loop iteration first increments "i", then it
check for error

[PATCH] i386: In assign_irq_vector look at all vectors before giving up
When the world was a simple and static place setting up irqs was easy.
It sufficed to allocate a linux irq number and a find a free cpu
vector we could receive that linux irq on. In those days it was
a safe assumption that any allocated vector was actually in use
so after one global pass through all of the vectors we would have
none left.
These days things are much more dynamic with interrupt controllers
(in the form of MSI or MSI-X) appearing on plug in cards and linux
irqs appearing and disappearing. As these irqs come and go vectors
are allocated and freed, invalidating the ancient assumption that all
allocated vectors stayed in use forever.
So this patch modifies the vector allocator to walk through every
possible vector before giving up, and to check to see if a vector
is in use before assigning it. With these changes we stop leaking
freed vectors and it becomes possible to allocate and free irq vectors
all day long.
This changed was modeled after the vector allocator on x86_64 where
this limitation has already been removed. In essence we don't update
the static variables that hold the position of the last vector we
allocated until have successfully allocated another vector. This
allows us to detect if we have completed one complete scan through
all of the possible vectors.

make possible things like reallocation of blocks on the fly, and we also uses
this pointer for indication, what actually we allocate data block or meta data

Fix balance_dirty_page() calculations with CONFIG_HIGHMEM
This makes balance_dirty_page() always base its calculations on the
amount of non-highmem memory in the machine, rather than try to base it

mapping it was writing wasn't highmem capable.
This not only fixes a situation where two different writers can have
wildly different notions about what is a "balanced" dirty state, but it
also means that people with highmem machines don't run into an OOM
situation when regular memory fills up with dirty pages.
We used to try to handle the latter case by scaling down the dirty_ratio
if the machine had a lot of highmem pages in page_writeback_init(), but
it wasn't aggressive enough for some situations, and since basing the
dirty ratio on highmem memory was broken in the first place, let's just

This patch reverts the semantics of card->dev to the former version,

card->dev or card->card_dev according to CONFIG_SYSFS_DEPRECATED to
keep the tree compatibility.
Also, card* isn't created if CONFIG_SYSFS_DEPRECATED is enabled. The

A stupid bug has been plaguing the sys_pciconfig_iobase on ppc64. It wasn't
noticed until recently as it seems to not affect G5s but it's been causing
problems running X servers on some other machines recently. The bus number
matching was bogus.

ahci: port_no should be used when clearing IRQ in ahci_thaw()
ap->id is logcial port ID which is unique among all ATA ports and
doesn't have anything to do with hardware port index. ap->port_no is
the hardware port index and thus should be used when clearing IRQ mask
in ahci_thaw().

[SPARC64]: Set g4/g5 properly in sun4v dtlb-prot handling.
Mirror the logic in the sun4u handler, we have to update
both registers even when we branch out to window fault
fixup handling.
The way it works is that if we are in etrap processing a
fault already, g4/g5 holds the original fault information.
If we take a window spill fault while doing etrap, then
we put the window spill fault info into g4/g5 and this is
what the top-level fault handler ends up processing first.
Then we retry the originally faulting instruction, and
process the original fault at that time.
This is all necessary because of how constrained the trap
registers are in these code paths. These cases trigger
very rarely, so even if there is some performance implication
it's doesn't happen very often. In fact the rarity is why
it took so long to trigger and find this particular bug.

Fix Maple PATA IRQ assignment.
On the Maple board, the AMD8111 IDE is in legacy mode... except that it
appears on IRQ 20 instead of IRQ 15. For drivers/ide this was handled by
the architecture's "pci_get_legacy_ide_irq()" function, but in libata we
just hard-code the numbers 14 and 15.
This patch provides asm-powerpc/libata-portmap.h which maps the IRQ as
appropriate, having added a pci_dev argument to the
ATA_{PRIM,SECOND}ARY_IRQ macros.
There's probably a better way to do this -- especially if we observe
that the _only_ case in which this seemingly-generic
"pci_get_legacy_ide_irq()" function returns anything other than 14 and
15 for primary and secondary respectively is the case of the AMD8111 on
the Maple board -- couldn't we handle that with a special case in the
pata_amd driver, or perhaps with a PCI quirk for Maple to switch it into
native mode during early boot and assign resources properly?

ahci: use 0x80 as wait stat value instead of 0xff
Before hardreset, ahci initialized stat part of received FIS area to
0xff to wait for the first D2H Reg FIS which would change the value to
device ready state. This used to work but now libata considers status
value of 0xff as device not present making this wait prone to failure.
This patch makes ahci use 0x80 for the wait stat value instead of
0xff to fix the above problem.
