DVB: fix dvb_pll_attach for mt352/zl10353 in cx88-dvb, and nxt200x Typical wiring of MT352, ZL10353, NXT2002 and NXT2004 based tuners differ from dvb-pll's expectation that the PLL is directly accessible. On these boards, the PLL is actually hidden behind the demodulator, and as such can only be accessed via the demodulator's interface. It was failing to communicate with the PLL during an attach test and subsequently not connecting the tuner ops. By passing a NULL I2C bus handle to dvb_pll_attach, this accessibility check can be bypassed. Do this for the affected boards. Also fix a possible NULL dereference at sleep time, which would otherwise be exposed by this change. This patch has been backported to the 2.6.18.y stable kernel series from the original changesets from Chris Pascoe and Michael Krufky, already present in the upstream 2.6.19 kernel tree.

This fixes a netdev watchdog timeout problem. The problem is caused by a needed netif_tx_disable in the hardware calibration code and can be shown by the following timegraph. |---5secs - ~10 jiffies time---|---|OOPS ^ ^ last real TX periodic work stops netif At OOPS, the following happens: The watchdog timer triggers, because the timeout of 5secs is over. The watchdog first checks for stopped TX. _Usually_ TX is only stopped from the TX handler to indicate a full TX queue. But this is different. We need to stop TX here, regardless of the TX queue state. So the watchdog recognizes the stopped device and assumes it is stopped due to full TX queues (Which is a _wrong_ assumption in this case). It then tests how far the last TX has been in the past. If it's more than 5secs (which is the case for low or no traffic), it will fire a TX timeout. Acked-by:

1) probe_other_fhcs() wants to see only non-central FHC busses, so skip FHCs that don't sit off the root 2) Like SBUS, FHC can lack the appropriate address and size cell count properties, so add an of_busses[] entry and handlers for that. 3) Central FHC irq translator probing was buggy. We were trying to use dp->child in irq_trans_init but that linkage is not setup at this point. So instead, pass in the parent of "dp" and look for the child "fhc" with parent "central". Thanks to the tireless assistence of Ben Collins in tracking down these problems and testing out these fixes. Signed-off-by:

[SERIAL] Fix oops when removing suspended serial port A serial card might have been removed when the system is resumed. This results in a suspended port being shut down, which results in the ports shutdown method being called twice in a row. This causes BUGs.

Failing context is a multi threaded process context and the failing sequence is as follows. One thread T0 doing self modifying code on page X on processor P0 and another thread T1 doing COW (breaking the COW setup as part of just happened fork() in another thread T2) on the same page X on processor P1. T0 doing SMC can endup modifying the new page Y (allocated by the T1 doing COW on P1) but because of different I/D TLB's, P0 ITLB will not see the new mapping till the flush TLB IPI from P1 is received. During this interval, if T0 executes the code created by SMC it can result in an app error (as ITLB still points to old page X and endup executing the content in page X rather than using the content in page Y). Fix this issue by first clearing the PTE and flushing it, before updating it with new entry. Hugh sayeth: I was a bit sceptical, in the habit of thinking that Self Modifying Code must look such issues itself: but I guess there's nothing it can do to avoid this one. Fair enough, what you're changing it to is pretty much what powerpc and s390 were already doing, and is a more robust way of proceeding, consistent with how ptes are set everywhere else. The ptep_clear_flush is a bit heavy-handed (it's anxious to return the pte that was atomically cleared), but we'd have to wander through lots of arches to get the right minimal behaviour. It'd also be nice to eliminate ptep_establish completely, now only used to define other macros/inlines: it always seemed obfuscation to me, what you've got there now is clearer. Let's put those cleanups on a TODO list. Signed-off-by:

The clocksource infrastructure introduced with commit ad596171 broke 31 bit s390. The reason is that the do_div() primitive for 31 bit always had a restriction: it could only divide an unsigned 64 bit integer by an unsigned 31 bit integer. The clocksource code now uses do_div() with a base value that has the most significant bit set. The result is that clock->cycle_interval has a funny value which causes the linux time to jump around like mad. The solution is "obvious": implement a proper __div64_32 function for 31 bit s390.

The whole idea with the NOTRACK netfilter target is that you can force the netfilter code to avoid connection tracking, and all costs assosciated with it, by making traffic match a NOTRACK rule. But this is totally broken by the fact that we do a checksum calculation over the packet before we do the NOTRACK bypass check, which is very expensive. People setup NOTRACK rules explicitly to avoid all of these kinds of costs. This patch from Patrick, already in Linus's tree, fixes the bug. Move the check for ip_conntrack_untracked before the call to skb_checksum_help to fix NOTRACK excemptions from NAT. Pre-2.6.19 NAT code breaks TSO by invalidating hardware checksums for every packet, even if explicitly excluded from NAT through NOTRACK. 2.6.19 includes a fix that makes NAT and TSO live in harmony, but the performance degradation caused by this deserves making at least the workaround work properly in -stable.

This patch has already been submitted for inclusion in the 2.6.19 tree, but not backported to the 2.6.18. Please pull the bug fix below into the stable tree for the 2.6.18.1 release. The purpose of the code being modified is to determine the location of the calgary chip address space. This is done by a magical formula of FE0MB-8MB*OneBasedChassisNumber+1MB*(RioNodeId-ChassisBase) to find the offset where BIOS puts it. In this formula, OneBasedChassisNumber corresponds to the NUMA node, and rionodeid is always 2 or 3 depending on which chip in the system it is. The problem was that we had an off by one error that caused us to account some busses to the wrong chip and thus give them the wrong address space. Fixes RH bugzilla #203971. Signed-off-by:

The recent fix to invalidate_inode_pages() (git commit 016eb4a0) managed to unfix invalidate_inode_pages2(). The problem is that various bits of code in the kernel can take transient refs on pages: the page scanner will do this when inspecting a batch of pages, and the lru_cache_add() batching pagevecs also hold a ref. Net result is transient failures in invalidate_inode_pages2(). This affects NFS directory invalidation (observed) and presumably also block-backed direct-io (not yet reported). Fix it by reverting invalidate_inode_pages2() back to the old version which ignores the page refcounts. We may come up with something more clever later, but for now we need a 2.6.18 fix for NFS.
