The <linux/serial_core.h> header refers to handle_sysrq(), but does not
include <linux/sysrq.h> which provides a declaration of the function. This
may result in an implicit declaration and a warning if the actual one is
seen later on.

Move the forward declaration of fb_class from drivers/video/console/fbcon.h to
<linux/fb.h>, together with the other forward declarations related to
drivers/video/fbmem.c.
This kills the following sparse warning:

On systems with huge amount of physical memory, VFS cache and memory memmap
may eat all available system memory under 4G, then the system may fail to
allocate swiotlb bounce buffer.
There was a fix for this issue in arch/x86_64/mm/numa.c, but that fix dose
not cover sparsemem model.
This patch add fix to sparsemem model by first try to allocate memmap above
4G.

The Via VT3351 APIC does not play well with MSI and unleashes a flood
of APIC errors when MSI is used to deliver interrupts. The problem
was recently exposed when the atl1 network device driver, which enables
MSI by default, stimulated APIC errors on an Asus M2V mainboard, which
employs the Via VT3351.
See http://bugzilla.kernel.org/show_bug.cgi?id=8472 for additional
details on this bug.

I've been seeing lots of messages like these:
eth0: No interrupt was generated using MSI, switching to INTx mode. Please
report this failure to the PCI maintainer and include system chipset
information.
On several systems that use the following Severworks HT1000 (also sometimes
labeled as a Broadcom chipset as well) bridge chips. It doesn't appear MSI
works well (if at all) on these systems.

get_next_timer_interrupt() returns a delta of (LONG_MAX > 1) in case
there is no timer pending. On 64 bit machines this results in a
multiplication overflow in tick_nohz_stop_sched_tick().
Reported by: Dave Miller <davem@davemloft.net>
Make the return value a constant and limit the return value to a 32 bit
value.
When the max timeout value is returned, we can safely stop the tick
timer device. The max jiffies delta results in a 12 days timeout for
HZ=1000.
In the long term the get_next_timer_interrupt() code needs to be
reworked to return ktime instead of jiffies, but we have to wait until
the last users of the original NO_IDLE_HZ code are converted.

1. Add support for decoding IPv6 address. I know it was manually added in
the header file, but not in the template file. That wouldn't work.

When the packet size is changed by the FTP NAT helper, the connection
tracking helper adjusts the sequence number of the newline character
by the size difference. This is wrong because NAT sequence number
adjustment happens after helpers are called, so the unadjusted number
is compared to the already adjusted one.

* 'fixes' of git://git.linux-nfs.org/pub/linux/nfs-2.6:
NFS: Fix nfs_direct_dirty_pages()
NFS: Fix handful of compiler warnings in direct.c
NFS: Avoid a deadlock situation on write
When processes are allowed to attempt to lock a non-contiguous range of nfs
write requests, it is possible for generic_writepages to 'wrap round' the
address space, and call writepage() on a request that is already locked by
the same process.
We avoid the deadlock by checking if the page index is contiguous with the
list of nfs write requests that is already held in our
nfs_pageio_descriptor prior to attempting to lock a new request.

It is possible that real data or metadata follows the bitmap without full page

So limit the last write to be only the required number of bytes, rounded up to

Steve Hawkes discovered a problem where recalc_sigpending_tsk was called in
do_sigaction but no signal_wake_up call was made, preventing later signals
from waking up blocked threads with TIF_SIGPENDING already set.
In fact, the few other calls to recalc_sigpending_tsk outside the signals
code are also subject to this problem in other race conditions.
This change makes recalc_sigpending_tsk private to the signals code. It
changes the outside calls, as well as do_sigaction, to use the new
recalc_sigpending_and_wake instead.
