This patch fixes a few issues in offb:
- A test was inverted causing the palette hack to never work
(no device node was passed down to the init function)
- Some cards seem to have their assigned-addresses property in a random
order, thus we need to try using of_get_pci_address() first, which will
fail if it's not a PCI device, and fallback to of_get_address() in that
case. of_get_pci_address() properly parsees assigned-addresses to test
the BAR number and thus will get it right whatever the order is.
- Some cards (like GXT4500) provide a linebytes of 0xffffffff in the
device-tree which does no good. This patch handles that by using the
screen width when that happens. (Also fixes btext.c while at it).
- Add detection of the GXT4500 in addition to the GXT2000 for the
palette hacks (we use the same hack, palette is linear in register space
at offset 0x6000).

The check to see if the firmware drops interrupts during a
SAL_CACHE_FLUSH is done to early in the boot. SAL_CACHE_FLUSH expects
to be able to make PAL calls in virtual mode, on some cell based
machines a fault occurs causing a MCA. This patch moves the check
after mmu_context_init so the TLB and VHPT are properly setup.

The information in MCA records is filled in slightly differently on
Montecito than on Madison/McKinley. Usually, the cache check and bus
check target identifiers have the same address. On Montecito the
cache check and bus check target identifiers can be different if
a corrected error (ie SBE or unconsumed poison data) was encountered and
then an uncorrected error (ie DBE) was consumed. In that case, the
cache check target identifier is the physical address of the DBE (that
caused the MCA to surface) while the bus check target identifier is the
physical address of the SBE. This patch correctly finds the target
identifier that triggered the MCA.
If there are multiple valid cache target identifiers in the same
error record then use the one with the lowest cache level.

Since we already moved to GENERIC_TIME, we should implement alternatives
of old do_gettimeoffset routines to get sub-jiffies resolution from
gettimeofday(). This patch includes:
* MIPS clocksource support (based on works by Manish Lachwani).
* remove unused gettimeoffset routines and related codes.
* remove unised 64bit do_div64_32().
* simplify mips_hpt_init. (no argument needed, __init tag)
* simplify c0_hpt_timer_init. (no need to write to c0_count)
* remove some hpt_init routines.
* mips_hpt_mask variable to specify bitmask of hpt value.
* convert jmr3927_do_gettimeoffset to jmr3927_hpt_read.
* convert ip27_do_gettimeoffset to ip27_hpt_read.
* convert bcm1480_do_gettimeoffset to bcm1480_hpt_read.
* simplify sb1250 hpt functions. (no need to subtract and shift)

In very rare circumstances would we be pruning a merged request and at
the same time delete the implicated cfqq from the rr_list, and not readd
it when the merged request got added. This could cause io stalls until
that process issued io again.
Fix it up by putting the rr_list add handling into cfq_add_rq_rb(),
identical to how pruning is handled in cfq_del_rq_rb(). This fixes a
hang reproducible with fsx-linux.

The conversion from IPR-IRQ to IRQ-chip resulted in the
ipr data being allocated in a local variable in
make_ipr_irq - breaking anything using IPR interrupts.
This changes all of the callers of make_ipr_irq to
allocate a static structure containing the IPR data which
is then passed to make_ipr_irq. This removes the need for
make_ipr_irq to allocate any additional space for the IPR
information.

There's a bug in the seqfile show operation for flowlabel objects, where
each hash chain is traversed cumulatively for each element. The following
function is called for each element of each chain:
static void ip6fl_fl_seq_show(struct seq_file *seq, struct ip6_flowlabel *fl)
{
while(fl) {
seq_printf...
fl = fl->next;
}
}
Thus, objects can appear mutliple times when reading
/proc/net/ip6_flowlabel, as the above is called for each element in the
chain.
The solution is to remove the while() loop from the above, and traverse
each chain exactly once, per the patch below. This also removes the
ip6fl_fl_seq_show() function, which does nothing else.

Currently, when an application requests a lease for a flowlabel via the

application in this case.

Every time SCTP creates a temporary association, the stack hashes it,
puts it on a list of endpoint associations and increments the backlog.
However, the lifetime of a temporary association is the processing time
of a current packet and it's destroyed after that. In fact, we don't
really want anyone else finding this association. There is no reason to
do this extra work.

This patch makes two changes to protect applications from either removing or
tampering with the CIPSOv4 IP option on a socket. The first is the requirement
that applications have the CAP_NET_RAW capability to set an IPOPT_CIPSO option
on a socket; this prevents untrusted applications from setting their own
CIPSOv4 security attributes on the packets they send. The second change is to
SELinux and it prevents applications from setting any IPv4 options when there
is an IPOPT_CIPSO option already present on the socket; this prevents
applications from removing CIPSOv4 security attributes from the packets they
send.

There is a number of issues in parsing user-provided table in
translate_table(). Malicious user with CAP_NET_ADMIN may crash system by
passing special-crafted table to the *_tables.
The first issue is that mark_source_chains() function is called before entry
content checks. In case of standard target, mark_source_chains() function
uses t->verdict field in order to determine new position. But the check, that
this field leads no further, than the table end, is in check_entry(), which
is called later, than mark_source_chains().
The second issue, that there is no check that target_offset points inside
entry. If so, *_ITERATE_MATCH macro will follow further, than the entry
ends. As a result, we'll have oops or memory disclosure.
And the third issue, that there is no check that the target is completely
inside entry. Results are the same, as in previous issue.

There's a bug in the seqfile handling for /proc/net/ip6_flowlabel, where,
after finding a flowlabel, the code will loop forever not finding any
further flowlabels, first traversing the rest of the hash bucket then just
looping.
This patch fixes the problem by breaking after the hash bucket has been
traversed.
Note that this bug can cause lockups and oopses, and is trivially invoked
by an unpriveleged user.

I was looking at a RHEL5 bug report involving Xen and SCTP
(https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=212550).
It turns out that SCTP wasn't written to handle skb fragments at
all. The absence of any calls to skb_may_pull is testament to
that.
It just so happens that Xen creates fragmented packets more often
than other scenarios (header & data split when going from domU to
dom0). That's what caused this bug to show up.
Until someone has the time sits down and audits the entire net/sctp
directory, here is a conservative and safe solution that simply
linearises all packets on input.

skb_segment fails to segment linear packets correctly because it
tries to write all linear parts of the original skb into each
segment. This will always panic as each segment only contains
enough space for one MSS.
This was not detected earlier because linear packets should be
rare for GSO. In fact it still remains to be seen what exactly
created the linear packets that triggered this bug. Basically
the only time this should happen is if someone enables GSO
emulation on an interface that does not support SG.

atrtr_find() can return NULL, so do not blindly dereference
rt->dev before we check for rt being NULL.

Sealevel uses arp_broken_ops so it needs to depend on INET.

The code in schizo_irq_trans_init() should set irq_data->sync_reg
to the location of the SYNC register if this is Tomatillo, and set
it to zero otherwise. But that is not what it is doing.
As a result, non-Tomatillo systems were trying to access a
non-existent register resulting in bus errors at the first
PCI interrupt.
Thanks to Roland Stigge for the bug report.

Partitions are not limited to live within a device. So we should range
check after partition mapping.
Note that 'maxsector' was being used for two different things. I have
split off the second usage into 'old_sector' so that maxsector can be still
be used for it's primary usage later in the function.

There is no point to calling the lower umount_begin when the eCryptfs
umount_begin is called.
