If the next descriptor array entry cannot be allocated by dev_alloc_skb(),
return immediately so it is not dereferenced later. We cannot register the
device with a partial descriptor list.

The enablement of 64k pages on pseries platforms exposed a bug in
the RTAS mechanism for updating firmware. RTAS assumes 4k for flash
block and list sizes, and use of any other sizes results in a failure,
even though PAPR does not specify any such requirement.
This patch changes the rtas_flash module to force the use of 4k memory
block and list sizes when preparing and sending a firmware image to
RTAS. The rtas_flash function now uses a slab cache of 4k blocks with
4k alignment, rather than get_zeroed_page(), to allocate the memory for
the flash blocks and lists. The 4k alignment requirement is specified
in PAPR.

The SMC and SCC hardware transmitter is enabled at the wrong
place. Simply writing twice to the non-console port, like
$ echo asdf > /dev/ttyCPM1
$ echo asdf > /dev/ttyCPM1
puts the shell into endless uninterruptible sleep, since the
transmitter is stopped after the first write, and is not enabled
before the shutdown function of the second write. Thus the transmit
buffers are never emptied.

Assure 4K alignment for firmware control blocks in 64K page mode,
because kzalloc()'s result address might not be 4K aligned if 64K
pages are enabled. Thus, we introduce wrappers called
ehca_{alloc,free}_fw_ctrlblock(), which use a slab cache for objects
with 4K length and 4K alignment in order to alloc/free firmware
control blocks in 64K page mode. In 4K page mode those wrappers just
are defines of get_zeroed_page() and free_page().

Some broken cards seem to process CMD1 even in stand-by state. The result is
that the card replies with ILLEGAL_COMMAND error for the next command sent
after rescanning. Currently the next command is select card, which would
return the error. But CMD7 does actually succeed and retries of the command
will timeout. The workaround is to poll card status after CMD1 to clear the
pending error.

Commit 6264d69d7df654ca64f625e9409189a0e50734e9 modified the nfsd_create()
error handling in such a way that nfsd_create will usually return
nfserr_perm even when succesful, if the export has the async export option.
This introduced a regression that could cause mkdir() to always return a
permissions error, even though the directory in question was actually
succesfully created.

aditional parameter update that is a function that is called whenever we want
to write to a drivers htirq configuration registers.

This refactoring actually optimizes the code a little by caching the value
that we think the device is programmed with instead of reading it back from
the hardware. Which simplifies the code a little and should speed things up a
bit.
This patch introduces the concept of a ht_irq_msg and modifies the
architecture read/write routines to update this code.
There is a minor consistency fix here as well as x86_64 forgot to initialize
the htirq as masked.

The basic issue is that despite have been deprecated and warned about as a
very bad thing in the man pages since its inception there are a few real
users of sys_sysctl. It was my assumption that because sysctl had been
deprecated for all of 2.6 there would be no user space users by this point,
so I initially gave sys_sysctl a very short deprecation period.
Now that I know there are a few real users the only sane way to proceed
with deprecation is to push the time limit out to a year or two work and
work with distributions that have big testing pools like fedora core to
find these last remaining users.
Which means that the sys_sysctl interface needs to be maintained in the
meantime.
Since I have provided a technical measure that allows us to add new sysctl
entries without reserving more binary numbers I believe that is enough to
fix the sys_sysctl binary interface maintenance problems, because there is
no longer a need to change the binary interface at all.
Since the sys_sysctl implementation needs to stay around for a while and
the worst of the maintenance issues that caused us to occasionally break
the ABI have been addressed I don't see any advantage in continuing with
the removal of sys_sysctl.
So instead of merely increasing the deprecation period this patch removes
the deprecation of sys_sysctl and modifies the kernel to compile the code
in by default.
With committing to maintain sys_sysctl we get all of the advantages of a
fast interface for anything that needs it. Currently sys_sysctl is about
5x faster than /proc/sys, for the same string data.

When ACPI && NUMA, pxm_to_node is used and it exists in drivers/acpi/numa.c
Tony said:
The patch makes sense ... if you pick both of "ACPI" and "NUMA", then you
need (and should automatically be given) ACPI_NUMA too.
The only open question is whether there is a better way of getting there.
Perhaps with less configuration options in the first place? We are heading
towards a future where so many systems will be NUMA that there would seem to
be little benefit in keeping ACPI_NUMA separate from ACPI ... but perhaps
we aren't quite there yet.

If there's a swap file on a software RAID, it should be possible to use this
file for saving the swsusp's suspend image. Also, this file should be
available to the memory management subsystem when memory is being freed before
the suspend image is created.
For the above reasons it seems that md_threads should not be frozen during the
suspend and the appended patch makes this happen, but then there is the
question if they don't cause any data to be written to disks after the suspend
image has been created, provided that all filesystems are frozen at that time.

There is a race between dev_create() and find_device().
If the mdptr has not yet been stored against a device, find_device() needs to
behave as though no device was found. It already returns NULL, but there is a
dm_put() missing: it must drop the reference dm_get_md() took.
The bug was introduced by dm-fix-mapped-device-ref-counting.patch.
It manifests itself if another dm ioctl attempts to reference a newly-created
device while the device creation ioctl is still running. The consequence is
that the device cannot be removed until the machine is rebooted. Certain udev
configurations can lead to this happening.

If the microcode driver is built in (rather than module) there are some,
ehm, interesting effects happening due to the new "call out to userspace"
behavior that is introduced.. and which runs too early. The result is a
boot hang; which is really nasty.
The patch below is a minimally safe patch to fix this regression for 2.6.19
by just not requesting actual microcode updates during early boot. (That
is a good idea in general anyway)
The "real" fix is a lot more complex given the entire cpu hotplug scenario
(during cpu hotplug you normally need to load the microcode as well); but
the interactions for that are just really messy at this point; this fix at
least makes it work and avoids a full detangle of hotplug.

Fixes Samba bugzilla #4176
When users do not specify their domain on mount, 2.6.18 started sending
default domain instead of a null domain (which was the only way on some
servers to use a default domain). Users of 2.6.18 who did not specify
their domain name on mounts to certain common Windows servers that were
members of a domain, but not the domain controller, would get mount
failures which they did not get in 2.6.18
This fixes that issue and should remove complaints about mount
behavior changing.

* merom:v2.6/linux:
x86-64: write IO APIC irq routing entries in correct order
x86-64: clean up io-apic accesses

|
This is the x86-64 version of f9dadfa71bc594df09044da61d1c72701121d802
that did the same thing on i386.
Since the "mask" bit is in the low word, when we write a new entry, we
need to write the high word first, before we potentially unmask it.
The exception is when we actually want to mask the interrupt, in which
case we want to write the low word first to make sure that the high word
doesn't change while the interrupt routing is still active.

order to then fix the ordering issues.
We move the accessor functions (that were only used by io_apic.c) out of
a header file, and use proper memory-mapped accesses rather than making
up our own "volatile" pointers.
