IPv6: preferred lifetime of address not getting updated
There's a bug in addrconf_prefix_rcv() where it won't update the
preferred lifetime of an IPv6 address if the current valid lifetime
of the address is less than 2 hours (the minimum value in the RA).
For example, If I send a router advertisement with a prefix that
has valid lifetime = preferred lifetime = 2 hours we'll build
this address:
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic
valid_lft 7175sec preferred_lft 7175sec
If I then send the same prefix with valid lifetime = preferred
lifetime = 0 it will be ignored since the minimum valid lifetime
is 2 hours:
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:1890:1109:a20:217:8ff:fe7d:4718/64 scope global dynamic
valid_lft 7161sec preferred_lft 7161sec
But according to RFC 4862 we should always reset the preferred lifetime
even if the valid lifetime is invalid, which would cause the address
to immediately get deprecated. So with this patch we'd see this:
5: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:1890:1109:a20:21f:29ff:fe5a:ef04/64 scope global deprecated dynamic
valid_lft 7163sec preferred_lft 0sec
The comment winds-up being 5x the size of the code to fix the problem.
Update the preferred lifetime of IPv6 addresses derived from a prefix
info option in a router advertisement even if the valid lifetime in
the option is invalid, as specified in RFC 4862 Section 5.5.3e. Fixes
an issue where an address will not immediately become deprecated.

MIPS: BC47xx: Fix SSB irq setup
The current ssb irq setup in ssb_mipscore_init has the problem that it
configures some device on some irq without checking that the irq is not
taken by an other device.
For example in my case PCI host is on irq 0 and IPSEC on irq 3.
The current code:
- store in dev->irq that IPSEC irq is 3 + 2
- do a set_irq 0->3 on PCI host
But now IPSEC irq is not routed anymore to the mips code and dev->irq is
wrong. This causes a problem described in [1].
This patch tries to solve the problem by making set_irq configure the
device we want to take the irq on the shared irq0. The previous example
becomes:
- store in dev->irq that IPSEC irq is 3 + 2
- do a set_irq 0->3 on PCI host:
- irq 3 is already taken by IPSEC. do a set_irq 3->0 on IPSEC
I also added some code to print the irq configuration after irq setup to
allow easier debugging. And I add extra checking in ssb_mips_irq to report
device without irq or device with not routed irq.

x86, kvm: Fix section mismatches in kvm.c
The function paravirt_ops_setup() has been refering the
variable no_timer_check, which is a __initdata. Thus generates
the following warning. paravirt_ops_setup() function is called
from kvm_guest_init() which is a __init function. So to fix
this we mark paravirt_ops_setup as __init.
The sections-check output that warned us about this was:
LD arch/x86/built-in.o
WARNING: arch/x86/built-in.o(.text+0x166ce): Section mismatch in
reference from the function paravirt_ops_setup() to the variable
.init.data:no_timer_check
The function paravirt_ops_setup() references
the variable __initdata no_timer_check.
This is often because paravirt_ops_setup lacks a __initdata
annotation or the annotation of no_timer_check is wrong.

I prefer to just invert the order of the fixmap declaration.
It's simpler and more straightforward.
Backward fixmaps seems to be used by both x86 32 and 64.
It's really rare but a nasty bug, because it only hurts when
instructions to patch are crossing a page boundary. If this
happens, the fixmap write accesses will spill on the following
fixmap, which may very well crash the system. And this does not
crash the system, it could leave illegal instructions in place.
Thanks Masami for finding this.
It seems to have crept into the 2.6.30-rc series, so this calls
for a -stable inclusion.

parisc: fix "delay!" timer handling
Rewrote timer_interrupt() to properly handle the "delayed!" case.
If we used floating point math to compute the number of ticks that had
elapsed since the last timer interrupt, it could take up to 12K cycles
(emperical!) to handle the interrupt. Existing code assumed it would
never take more than 8k cycles. We end up programming Interval Timer
to a value less than "current" cycle counter. Thus have to wait until
Interval Timer "wrapped" and would then get the "delayed!" printk that
I moved below.
Since we don't really know what the upper limit is, I prefer to read
CR16 again after we've programmed it to make sure we won't have to
wait for CR16 to wrap.
Further, the printk was between reading CR16 (cycle couner) and writing CR16
(the interval timer). This would cause us to continue to set the interval
timer to a value that was "behind" the cycle counter. Rinse and repeat.
So no printk's between reading CR16 and setting next interval timer.

Correct firmware encoding is 8 bit major, 8 bit minor and
16 bit subversion. Flash has sizes rightly set, but original
driver submission messed it leaving 16 bit major and 8 bit
subversion.
Also fix a infinite loop when cut-thru file firmware is
invalid.

ieee1394: sbp2: add support for disks >2 TB (and 16 bytes long CDBs)

is notably necessary for READ CAPACITY(16) and friends, i.e. support of

x86: fix power-of-2 round_up/round_down macros
These macros had two bugs:
- the type of the mask was not correctly expanded to the full size of
the argument being expanded, resulting in possible loss of high bits
when mixing types.
- the alignment argument was evaluated twice, despite the macro looking
like a fancy function (but it really does need to be a macro, since
it works on arbitrary integer types)
Noticed by Peter Anvin, and with a fix that is a modification of his
suggestion (bug noticed by Yinghai Lu).

Btrfs: update backrefs while dropping snapshot
The new backref format has restriction on type of backref item. If a tree
block isn't referenced by its owner tree, full backrefs must be used for the
pointers in it. When a tree block loses its owner tree's reference, backrefs
for the pointers in it should be updated to full backrefs. Current
btrfs_drop_snapshot misses the code that updates backrefs, so it's unsafe for
general use.
This patch adds backrefs update code to btrfs_drop_snapshot. It isn't a
problem in the restricted form btrfs_drop_snapshot is used today, but for
general snapshot deletion this update is required.

Btrfs: account for space we may use in fallocate
Using Eric Sandeen's xfstest for fallocate, you can easily trigger a ENOSPC
panic on btrfs. This is because we do not account for data we may use when
doing the fallocate. This patch fixes the problem by properly reserving space,
and then just freeing it when we are done. The reservation stuff was made with
delalloc in mind, so its a little crude for this case, but it keeps the box
from panicing.
