PV on HVM guests map GSIs into event channels. At restore time the
event channels are resumed by restore_pirqs.
Device drivers might try to register the same GSI again through ACPI at
restore time, but the GSI has already been mapped and bound by
restore_pirqs. This patch detects these situations and avoids
mapping the same GSI multiple times.
Without this patch we get:
(XEN) irq.c:2235: dom4: pirq 23 or emuirq 28 already mapped
and waste a pirq.

Pull sparc updates from David Miller:
1) Kill off support for sun4c and Cypress sun4m chips.
And as a result we were able to also kill off that ugly btfixup thing
that required multi-stage links of the final vmlinux image in the
Kbuild system. This should make the kbuild maintainers really happy.
Thanks a lot to Sam Ravnborg for his tireless efforts to get this
going.
2) Convert sparc64 to nobootmem. I suspect now with sparc32 being a lot
cleaner, it should be able to fall in line and modernize in this area
too.
3) Make sparc32 use generic clockevents, from Tkhai Kirill.
[ I fixed up the BPF rules, and tried to clean up the build rules too.
But I don't have - or want - a sparc cross-build environment, so the
BPF rule bug and the related build cleanup was all done with just a
bare "make -n" pseudo-test. - Linus ]

Pull networking changes from David Miller:
1) Get rid of the error prone NLA_PUT*() macros that used an embedded
goto.
2) Kill off the token-ring and MCA networking drivers, from Paul
Gortmaker.
3) Reduce high-order allocations made by datagram AF_UNIX sockets, from
Eric Dumazet.
4) Add PTP hardware clock support to IGB and IXGBE, from Richard
Cochran and Jacob Keller.
5) Allow users to query timestamping capabilities of a card via
ethtool, from Richard Cochran.
6) Add loadbalance mode to the teaming driver, from Jiri Pirko. Part
of this is that we can now have BPF filters not attached to sockets,
and the loadbalancing function is calculated using one.
7) Francois Romieu went through the network drivers removing gratuitous
uses of netdev->base_addr, perhaps some day we can remove it
completely but it's used for ISA probing still.
8) Add a BPF JIT for sparc. I know, who cares, right? :-)
9) Move networking sysctl registry away from using the compatability
mode interfaces in the sysctl code. From Eric W Biederman.
10) Pavel Emelyanov added a way to save and restore TCP socket state via
TCP_REPAIR, TCP_REPAIR_QUEUE, and TCP_QUEUE_SEQ socket options as
well as a way to forcefully bind a socket to a port via the
sk->sk_reuse value SK_FORCE_REUSE. There is also a
TCP_REPAIR_OPTIONS which allows to reinstante the TCP options
enabled on the connection.
11) Several enhancements from Eric Dumazet that, in particular, can
enhance splice performance on TCP sockets significantly.
a) Reset the offset of the per-socket sendmsg page when we know
we're the only use of the page in linear_to_page().
b) Add facilities such that skb->data can be backed a page rather
than SLAB kmalloc'd memory. In particular devices which were
receiving into linear RX buffers can now end up providing paged
data.
The big result is that code like splice and GRO do not have to copy
any more.
12) Allow a pure sender to more gracefully handle ACK backlogs in TCP.
What can happen at high rates is that the sender hasn't grown his
receive buffer limits at all (he's not receiving data so really
doesn't need to), but the non-data ACKs consume receive buffer
space.
sk_add_backlog() is too aggressive in dropping frames in this case,
so relax it's requirements by using the receive buffer plus the send
buffer limit as the backlog limit instead of just the former.
Also from Eric Dumazet.
13) Add ipv6 support to L2TP, from Benjamin LaHaise, James Chapman, and
Chris Elston.
14) Implement TCP early retransmit (RFC 5827), from Yuchung Cheng.
Basically, we can start fast retransmit before hiting the dupack
threshold under certain conditions.
15) New CODEL active queue management packet scheduler, from Eric
Dumazet based upon initial work by Dave Taht.
Basically, the big feature is that packets are dropped (or ECN bits
are set) based upon how long packets live in the queue, rather than
the queue length (which is what RED uses).

xhci/usb: Build error fixes for 3.5
Hi Greg,
Here's four patches that fix the build errors introduced by the USB 3.0 Link PM
patches. Please pull for inclusion in 3.5.

Fengguang reports that the xHCI driver isn't linked properly on his
machine:
ERROR: "__udivdi3" [drivers/usb/host/xhci-hcd.ko] undefined!
ERROR: "handle_edge_irq" [drivers/gpio/gpio-pch.ko] undefined!
ERROR: "irq_to_desc" [drivers/gpio/gpio-pch.ko] undefined!
The driver compiles fine on my 64-bit box (gcc version 4.6.1).
Fengguang thinks it's because the xHCI driver was using DIV_ROUND_UP()
instead of DIV_ROUND_UP_ULL() with arguments that were unsigned long
long variables.

The USB 2.0 Link PM code is conditionally compiled when
CONFIG_USB_SUSPEND=y. I believe that's a mistake, since Link PM is not
directly related to USB device suspend and Link PM is implemented
without relying on any of the suspend code in the USB core. For now,
keep the USB 2.0 Link PM code conditionally compiled if
CONFIG_USB_SUSPEND=y.
This patch does move the code to implement USB 3.0 Link PM out of the
xHCI driver #ifdefs for CONFIG_USB_SUSPEND and moves it into a section
dependent on CONFIG_PM. The USB core functions for USB 3.0 Link PM are
already conditionally compiled when CONFIG_PM=y.

This teaches vfs_fstat() to use the appropriate f[get|put]_light
functions, allowing it to avoid some unnecessary locking for the common
case.
More noticeably, it also cleans up and simplifies the "getname_flags()"
function, which now relies on the architecture strncpy_from_user() doing
all the user access checks properly, instead of hacking around the fact
that on x86 it didn't use to do it right (see commit 92ae03f2ef99: "x86:
merge 32/64-bit versions of 'strncpy_from_user()' and speed it up").
* vfs-cleanups:
VFS: make vfs_fstat() use f[get|put]_light()
VFS: clean up and simplify getname_flags()
x86: make word-at-a-time strncpy_from_user clear bytes at the end

xfstest 270 was causing quota reservations way beyond what was sane
(ten to hundreds of TB) for a 4GB filesystem. There's a sign problem
in the error handling path of xfs_bmapi_reserve_delalloc() because
xfs_trans_unreserve_quota_nblks() simple negates the value passed -
which doesn't work for an unsigned variable. This causes
reservations of close to 2^32 block instead of removing a
reservation of a handful of blocks.
Fix the same problem in the other xfs_trans_unreserve_quota_nblks()
callers where unsigned integer variables are used, too.

Previously we were only enabling the 64-bit jbd2 feature if the number
of blocks in the file system was greater 2**32-1. The problem with
this is that it makes it harder to test the 64-bit journal code paths
with small file systems, since a small test file system would with the
64-bit ext4 feature enable would use a 64-bit file system on-disk data
structures, but use a 32-bit journal.
This would also cause problems when trying to do an online resize to
grow the filesystem above the 2**32-1 boundary. Fortunately the patch
to support online resize for 64-bit file systems hasn't been merged
yet, so this problem hasn't arisen in practice.

This makes cp_new_stat() a bit more readable, and avoids having to
memset() the whole structure just to fill in a couple of padding fields.
This is another result of me looking at code generation of functions
that show up high on certain kernel profiles, and just going "Oh, let's
just clean that up".
Architectures that don't supply the #define to fill just the padding
fields will still fall back to memset().
* stat-cleanups:
vfs: don't force a big memset of stat data just to clear padding fields
vfs: de-crapify "cp_new_stat()" function

This series sanitizes the interface to unmap_vma(). The crazy interface
annoyed me no end when I was looking at unmap_single_vma(), which we can
spend quite a lot of time in (especially with loads that have a lot of
small fork/exec's: shell scripts etc).
Moving the nr_accounted calculations to where they belong at least
clarifies things a little. I hope to come back to look at the
performance of this later, but if/when I get back to it I at least don't
have to see the crazy interfaces any more.
* vm-cleanups:
vm: remove 'nr_accounted' calculations from the unmap_vmas() interfaces
vm: simplify unmap_vmas() calling convention

If kzalloc() returns a NULL here, we pass a NULL to
xencons_disconnect_backend() which will cause an Oops.

Currently, the memory target in the Xen selfballooning driver is mainly
driven by the value of "Committed_AS". However, there are cases in
which it is desirable to assign additional memory to be available for
the kernel, e.g. for local caches (which are not covered by cleancache),
e.g. dcache and inode caches.
This adds an additional tunable in the selfballooning driver (accessible
via sysfs) which allows the user to specify an additional constant
amount of memory to be reserved by the selfballoning driver for the
local domain.

Before we are able to add OF support, we really want to drop all the bloat
needed to register all the platform devices.

On MIPS we want to call of_irq_map_pci from inside
arch/mips/include/asm/pci.h:extern int pcibios_map_irq(
const struct pci_dev *dev, u8 slot, u8 pin);
For this to work we need to change several functions to const usage.

The git commit 1ff2b0c303698e486f1e0886b4d9876200ef8ca5
"xen: implement IRQ_WORK_VECTOR handler" added the functionality
to have a per-cpu "irqworkX" for the IPI APIC functionality.
However it missed the unbind when a vCPU is unplugged resulting
in an orphaned per-cpu interrupt line for unplugged vCPU:
30: 216 0 xen-dyn-event hvc_console
31: 810 4 xen-dyn-event eth0
32: 29 0 xen-dyn-event blkif
- 36: 0 0 xen-percpu-ipi irqwork2
- 37: 287 0 xen-dyn-event xenbus
+ 36: 287 0 xen-dyn-event xenbus
NMI: 0 0 Non-maskable interrupts
LOC: 0 0 Local timer interrupts
SPU: 0 0 Spurious interrupts

The dma_contiguous_remap() function clears existing section maps using
the wrong size (PGDIR_SIZE instead of PMD_SIZE). This is a bug which
does not affect non-LPAE systems, where PGDIR_SIZE and PMD_SIZE are the same.
On LPAE systems, however, this bug causes the kernel to hang at this point.
This fix has been tested on both LPAE and non-LPAE kernel builds.
