changing include/asm-generic/pgtable.h for non-mmu
There are some parts of include/asm-generic/pgtable.h that are relevant to
the non-mmu architectures. To make it easier to include this from them I
would like to ifdef the relevant parts.
Without this there is a handful of functions that are referenced in here
that are not defined on many non-mmu architectures. They could be defined
out of course, as an alternative approach.

finish i386 and x86-64 sysdata conversion
This patch finishes the i386 and x86-64 ->sysdata conversion and hopefully
also fixes Riku's and Andy's observed bugs. It is based on Yinghai Lu's
and Andy Whitcroft's patches (thanks!) with some changes:
- introduce pci_scan_bus_with_sysdata() and use it instead of
pci_scan_bus() where appropriate. pci_scan_bus_with_sysdata() will
allocate the sysdata structure and then call pci_scan_bus().
- always allocate pci_sysdata dynamically. The whole point of this
sysdata work is to make it easy to do root-bus specific things
(e.g., support PCI domains and IOMMU's). I dislike using a default
struct pci_sysdata in some places and a dynamically allocated
pci_sysdata elsewhere - the potential for someone indavertantly
changing the default structure is too high.
- this patch only makes the minimal changes necessary, i.e., the NUMA node is
always initialized to -1. Patches to do the right thing with regards
to the NUMA node can build on top of this (either add a 'node'
parameter to pci_scan_bus_with_sysdata() or just update the node
when it becomes known).
The patch was compile tested with various configurations (e.g., NUMAQ,
VISWS) and run-time tested on i386 and x86-64. Unfortunately none of my
machines exhibited the bugs so caveat emptor.
Andy, could you please see if this fixes the NUMA issues you've seen?
Riku, does this fix "pci=noacpi" on your laptop?

fix compilation with gcc 4.2
gcc-4.2 is a lot more picky about its symbol handling. EXPORT_SYMBOL no
longer works on symbols that are undefined or defined with static scope.
For example, with CONFIG_PROFILE off, I see:
kernel/profile.c:206: error: __ksymtab_profile_event_unregister causes a section type conflict
kernel/profile.c:205: error: __ksymtab_profile_event_register causes a section type conflict
This patch moves the EXPORTs inside the #ifdef CONFIG_PROFILE, so we
only try to export symbols that are defined.
Also, in kernel/kprobes.c there's an EXPORT_SYMBOL_GPL() for
jprobes_return, which if CONFIG_JPROBES is undefined is a static
inline and gives the same error.
And in drivers/acpi/resources/rsxface.c, there's an
ACPI_EXPORT_SYMBOPL() for a static symbol. If it's static, it's not
accessible from outside the compilation unit, so should bot be exported.
These three changes allow building a zx1_defconfig kernel with gcc 4.2
on IA64.

fix serial buffer memory leak
Patch
c5c34d4862e18ef07c1276d233507f540fb5a532 (tty: flush flip buffer on
ldisc input queue flush) introduces a race condition which can lead to memory
leaks.
The problem can be triggered when tcflush() is called when data are being
pushed to the line discipline driver by flush_to_ldisc().
flush_to_ldisc() releases tty->buf.lock when calling the line discipline
receive_buf function. At that poing tty_buffer_flush() kicks in and sets both
tty->buf.head and tty->buf.tail to NULL. When flush_to_ldisc() finishes, it
restores tty->buf.head but doesn't touch tty->buf.tail. This corrups the
buffer queue, and the next call to tty_buffer_request_room() will allocate a
new buffer and overwrite tty->buf.head. The previous buffer is then lost
forever without being released.
(Thanks to Laurent for the above text, for finding, disgnosing and reporting
the bug)
- Use tty->flags bits for the flush status.
- Wait for the flag to clear again before returning
- Fix the doc error noted
- Fix flush of empty queue leaving stale flushpending

spi_mpc83xx: fix prescale modulus calculation
Long ago I've noticed (but didn't pay much attention) that
spi_mpc83xx using PM calculations that differs from what
specs describe. I.e.
u8 pm = mpc83xx_spi->spibrg / (spi->max_speed_hz * 4);
While specs says: "The SPI baud rate generator clock source (either
system clock or system clock divided by 16, depending on DIV16 bit) is
divided by 4 * ([PM] + 1), a range from 4 to 64.".
Thus " - 1" is missing in the spi_mpc83xx's formula.
Why nobody noticed that bug? Probably because sysclk usually less then
user expects, e.g. you expect 200 MHz, but real clock is 198 MHz,
and integer rounding helps when this formula is used.
Suppose it's SPI in QE, SYSCLK at 198 MHz, thus SPIBRG at 99MHz, 25 MHz
requested.
PM = (99MHz / ( 25 MHz * 4 )), PM == 0, output SPICLK will be 24.75 MHz
At lower frequencies this bug is more noticeable, though.
And this bug shows itself in all its beauty if SYSCLK is equal or a bit
more than you expect (200 MHz SYSCLK, 100 MHz SPIBRG):
PM = (100MHz / ( 25 MHz * 4 )), PM == 1, output SPICLK will be 12.625 MHz!

stifb: detect cards in double buffer mode more reliably
Visualize-EG, Graffiti and A4450A graphics cards on PARISC can
be configured in double-buffer and standard mode, but the stifb
driver supports standard mode only.
This patch detects double-buffered cards more reliable.
It is a real bugfix for a very nasty problem for all parisc users which have
wrongly configured their graphic card. The problem: The stifb graphics driver
will not detect that the card is wrongly configured and then nevertheless just
enables the graphics mode, which it shouldn't. In the end, the user will see
no further updates / boot messages on the screen.
We had documented this problem already on our FAQ
(http://parisc-linux.org/faq/index.html#viseg "Why do I get corrupted graphics
with my Vis-EG/Graffiti/A4450A card?") but people still run into this problem.
So having this fix in as early as possible can help us.

x86_64: fix HPET init race
I have had four seperate system lockups attributable to this exact problem
in two days of testing. Instead of trying to handle all the weird end
cases and wrap, how about changing it to look for exactly what we appear
to want.
The following patch removes a couple races in setup_APIC_timer. One occurs
when the HPET advances the COUNTER past the T0_CMP value between the time
the T0_CMP was originally read and when COUNTER is read. This results in
a delay waiting for the counter to wrap. The other results from the counter
wrapping.
This change takes a snapshot of T0_CMP at the beginning of the loop and
simply loops until T0_CMP has changed (a tick has happened).
<later>
I have one small concern about the patch. I am not sure it meets the intent
as well as it should. I think we are trying to match APIC timer interrupts up
with the hpet counter increment. The event which appears to be disturbing
this loop in our test environment is the NMI watchdog. What we believe has
been happening with the existing code is the setup_APIC_timer loop has read
the CMP value, and the NMI watchdog code fires for the first time. This
results in a series of icache miss slowdowns and by the time we get back to
things it has wrapped.
I think this code is trying to get the CMP as close to the counter value as
possible. If that is the intent, maybe we should really be testing against a
"window" around the CMP. Something like COUNTER = CMP+/2. It appears COUNTER
should get advanced every 89nSec (IIRC). The above seems like an unreasonably
small window, but may be necessary. Without documentation, I am not sure of
the original intent with this code.
In summary, this code fixes my boot hangs, but since I am not certain of the
intent of the existing code, I am not certain this has not introduced new bugs
or unexpected behaviors.

SLUB: Fix dynamic dma kmalloc cache creation
The dynamic dma kmalloc creation can run into trouble if a
GFP_ATOMIC allocation is the first one performed for a certain size
of dma kmalloc slab.
- Move the adding of the slab to sysfs into a workqueue
(sysfs does GFP_KERNEL allocations)
- Do not call kmem_cache_destroy() (uses slub_lock)
- Only acquire the slub_lock once and--if we cannot wait--do a trylock.
This introduces a slight risk of the first kmalloc(x, GFP_DMA|GFP_ATOMIC)
for a range of sizes failing due to another process holding the slub_lock.
However, we only need to acquire the spinlock once in order to establish
each power of two DMA kmalloc cache. The possible conflict is with the
slub_lock taken during slab management actions (create / remove slab cache).
It is rather typical that a driver will first fill its buffers using
GFP_KERNEL allocations which will wait until the slub_lock can be acquired.
Drivers will also create its slab caches first outside of an atomic
context before starting to use atomic kmalloc from an interrupt context.
If there are any failures then they will occur early after boot or when
loading of multiple drivers concurrently. Drivers can already accomodate
failures of GFP_ATOMIC for other reasons. Retries will then create the slab.

SLUB: Remove checks for MAX_PARTIAL from kmem_cache_shrink
The MAX_PARTIAL checks were supposed to be an optimization. However, slab
shrinking is a manually triggered process either through running slabinfo
or by the kernel calling kmem_cache_shrink.
If one really wants to shrink a slab then all operations should be done
regardless of the size of the partial list. This also fixes an issue that
could surface if the number of partial slabs was initially above MAX_PARTIAL
in kmem_cache_shrink and later drops below MAX_PARTIAL through the
elimination of empty slabs on the partial list (rare). In that case a few
slabs may be left off the partial list (and only be put back when they
are empty).
