The patch aims to fix a performance issue for the syscall
personality(PER_LINUX32).

On IA-64 box, the syscall personality (PER_LINUX32) has poor performance
because it failed to find the Linux/x86 execution domain. Then it tried
to load the kernel module however it failed always and it used the default
execution domain PER_LINUX instead. Requesting kernel modules is very
expensive. It caused the performance issue. (see the function
lookup_exec_domain in kernel/exec_domain.c).

To resolve the issue, execution domain Linux/x86 is always registered in
initialization time for IA-64 architecture.

acpi_unregister_gsi() should "undo" what acpi_register_gsi() does.

On systems that have legacy interrupts, acpi_unregister_gsi erroneously calls
iosapci_unregister_intr() which is wrong to do and causes a loud warning.

acpi_unregister_gsi() should just return in these cases.

[Bug-fix for "[BUG?][2.6.25-mm1] sleeping during IRQ disabled"]

This patch does:
 - enable interrupts before calling schedule() as same as others, ex. x86
 - enable interrupts during ia64_do_signal() and ia64_sync_krbs()
 - do_notify_resume_user() is still called with interrupts disabled, since
   we can take short path of fsys_mode if-statement quickly.
 - pfm_handle_work() is also called with interrupts disabled, since
   it can deal interrupt mask within itself.

	- call SAL_CACHE_FLUSH
	- see if interrupt is still pending

can hang HP machines with buggy SAL_CACHE_FLUSH implementations.

Provide a kernel command-line argument to allow users skip this

Some IA64 machines map all cell-local memory above 4 GB (32 bit limit).
However, in most cases, the kernel needs some memory below that limit that is
DMA-capable. So in this machine configuration, the crashkernel will be reserved
above 4 GB.

For machines that use SWIOTLB implementation because they lack an I/O MMU
the low memory is required by the SWIOTLB implementation. In that case,
it doesn't make sense to reserve the crashkernel at all because it's unusable
for kdump.

A special case is the "hpzx1" machine vector. In theory, it has a I/O MMU, so
it can be booted above 4 GB. However, in the kdump case that is not possible
because of changeset 51b58e3e:

    On HP zx1 machines, the 'machvec=dig' parameter is needed for the kdump
    kernel to avoid problems with the HP sba iommu.  The problem is that during
    the boot of the kdump kernel, the iommu is re-initialized, so in-flight DMA
    from improperly shutdown drivers causes an IOTLB miss which leads to an
    MCA.  With kdump, the idea is to get into the kdump kernel with as little
    code as we can, so shutting down drivers properly is not an option.

    The workaround is to add 'machvec=dig' to the kdump kernel boot parameters.
    This makes the kdump kernel avoid using the sba iommu altogether, leaving
    the IOTLB intact.  Any ongoing DMA falls harmlessly outside the kdump
    kernel.  After the kdump kernel reboots, all devices will have been
    shutdown properly and DMA stopped.

This patch pushes that functionality into the sba iommu initialization
code, so that users won't have to find the obscure documentation telling
them about 'machvec=dig'.

This means that also for hpzx1 it's not possible to boot when all
memory is above the 4 GB limit. So the only machine vectors that can handle
this case are "sn2" and "uv".

There is a possible data race in the page table walking code. After the split
ptlock patches, it actually seems to have been introduced to the core code, but
even before that I think it would have impacted some architectures (powerpc
and sparc64, at least, walk the page tables without taking locks eg. see
find_linux_pte()).

The race is as follows:
The pte page is allocated, zeroed, and its struct page gets its spinlock
initialized. The mm-wide ptl is then taken, and then the pte page is inserted
into the pagetables.

At this point, the spinlock is not guaranteed to have ordered the previous
stores to initialize the pte page with the subsequent store to put it in the
page tables. So another Linux page table walker might be walking down (without
any locks, because we have split-leaf-ptls), and find that new pte we've
inserted. It might try to take the spinlock before the store from the other
CPU initializes it. And subsequently it might read a pte_t out before stores
from the other CPU have cleared the memory.

There are also similar races in higher levels of the page tables. They
obviously don't involve the spinlock, but could see uninitialized memory.

Arch code and hardware pagetable walkers that walk the pagetables without
locks could see similar uninitialized memory problems, regardless of whether
split ptes are enabled or not.

I prefer to put the barriers in core code, because that's where the higher
level logic happens, but the page table accessors are per-arch, and open-coding
them everywhere I don't think is an option. I'll put the read-side barriers
in alpha arch code for now (other architectures perform data-dependent loads
in order).

Various fixes to Atmel's high speed UDC driver.

  * Issue some missing disconnect() calls.  Currently they are only made
    when VBUS power goes away (on boards where the driver can sense such
    changes), but that's not enough for gadget drivers to clean out all
    the state that's needed.  Missing calls were:

      - After USB reset, before starting enumeration.
      - When unregistering a gadget driver, before unbind().

  * Don't assume gadget drivers provide disconnect callbacks; make sure
    to not call through a null pointer!

  * When the driver doesn't provide an unbind() callback, refuse to
    unregister it.

Also remove two bogus "error" messages:

  * Related to mis-handling of disconnect() ... don't emit error messages
    for disconnect() handlers that disable endpoints.  All of them should
    be doing that; the problem is (unfixed) oddness in atmel_usba_udc.

  * Don't emit a diagnostic for a curious and transient nonfatal error
    that shows up sometimes with EP0.

Those messages spammed syslog, for no good reason.

This removes a needless data structure from the serial gadget code;
it's a small code shrink, and a larger data shrink.

Since "struct usb_request" already has a "struct list_head" reserved
for use by gadget drivers, the serial gadget code doesn't need to
allocate wrapper structs to hold that list ... it can (and should!)
just use the list_head provided for that exact use.

Some cleanup/reorg of g_serial ... simplifying it, and disentangling
its structure so morphing it into a "function" driver (combinable with
other interfaces) should be less painful.

 - Remove most forward declarations
     * put tty and gadget driver structs after their contents
     * snug module init/exit decls next to their functions
     * reordered some functions

 - Other cleanup:
     * convert a funky macro to an inline function
     * snug up module params next to their declarations
     * add missing driver.owner
     * add separator lines between major driver sections

 - Add comments re potential parameter/#define changes:
     * only supports one port (shrank GS_NUM_PORTS)
     * changing from 9600-8-N-1 affects multiple sites

 - Remove net2280-specific optimization ... it was being done
   way too late, can be done by net2280 module options, and in
   any case doesn't matter at any sane serial data rates.

There are no behavioral changes, but the macro thing saves I-space.

The patch below is a necessary workaround to support the Zoom Telephonics Model 3095F V.92 USB Mini External modem, which fails to initialise properly during normal probing thus:

May  3 22:53:00 imcfarla kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references
May  3 22:53:00 imcfarla kernel: cdc_acm: probe of 5-2:1.0 failed with error -22

Adding the patch below causes the probing section to be skipped, and the modem
then initialises correctly.

the proposed patch allows the ET502HS HDSPA modem to be handled by the
"option" driver. It has been tested for 1 month and works reliably (no
oopses, no hangs, 300KB/s throughput).

The attached patch allows to bypass the ZeroCD mechanism for the ET502HS
HDSPA modem, so that it can be mounted as a network device.

This will be used by the wireless usb code, as well as potentially other
USB code.

This patch (as1087d) fixes a long-standing problem in usbcore: Device,
interface, and endpoint attributes aren't added until _after_ the
creation uevent has already been broadcast.

Unfortunately there are a few attributes which cannot be created that
early.  The "descriptors" attribute is binary and so must be created
separately.  The power-management attributes can't be created until
the dev/power/ group exists.  And the interface string can vary from
one altsetting to another, so it has to be created dynamically.
