Bhavesh P. Davda <bhavesh@avaya.com> noticed that SIGKILL wouldn't properly kill a process under just the right cicumstances: a stopped task that already had another signal queued would get the SIGKILL queued onto the shared queue, and there it would remain until SIGCONT. This simplifies the signal acceptance logic, and fixes the bug in the process. Losely based on an earlier patch by Bhavesh. Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

I believe the change that broke things is introduction of pci_fixup_parent_subordinate_busnr(). The patch here does two things: - hunk #1 should fix the problems you've seen when you boot without additional "pci" kernel options; - hunk #2 supposedly fixes boot with "pci=assign-busses" option which otherwise hangs Acer TM81xx machines as reported. Please try this with and without "pci=assign-busses". If it boots, I'd like to see 'lspci -vvx' for both cases.

This patch fixes a number of bugs. It cannot be reasonably split up in multiple fixes, since all bugs interact with each other and affect the same function: Bug #1: The event cache code cannot be called while a lock is held. Therefore, the call to ip_conntrack_event_cache() within ip_ct_refresh_acct() needs to be moved outside of the locked section. This fixes a number of 2.6.14-rcX oops and deadlock reports. Bug #2: We used to call ct_add_counters() for unconfirmed connections without holding a lock. Since the add operations are not atomic, we could race with another CPU. Bug #3: ip_ct_refresh_acct() lost REFRESH events in some cases where refresh (and the corresponding event) are desired, but no accounting shall be performed. Both, evenst and accounting implicitly depended on the skb parameter bein non-null. We now re-introduce a non-accounting "ip_ct_refresh()" variant to explicitly state the desired behaviour.

Since the introduction of TSO pcount a year ago, it has been possible for tcp_fragment() to cause packets_out to decrease. Prior to that, tcp_retrans_try_collapse() was the only way for that to happen on the retransmission path. When this happens with Reno, it is possible for sasked_out to become invalid because it is only an estimate and not tied to any particular packet on the retransmission queue. Therefore we need to adjust sacked_out as well as left_out in the Reno case. The following patch does exactly that. This bug is pretty difficult to trigger in practice though since you need a SACKless peer with a retransmission that occurs just as the cached MTU value expires.

Problem: In some circumstances, bd_claim() is returning the wrong error code. If we try to swapon an unused block device that isn't swap formatted, we get -EINVAL. But if that same block device is already mounted, we instead get -EBUSY, even though it still isn't a valid swap device. This issue came up on the busybox list trying to get the error message from "swapon -a" right. If a swap device is already enabled, we get -EBUSY, and we shouldn't report this as an error. But we can't distinguish the two -EBUSY conditions, which are very different errors. In the code, bd_claim() returns either 0 or -EBUSY, but in this case busy means "somebody other than sys_swapon has already claimed this", and _that_ means this block device can't be a valid swap device. So return -EINVAL there. Signed-off-by: NRob Landley <rob@landley.net> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>

User get *a lot* confused when consoles don't work but we don't report anything. And, as reported in the comment, using printk to report "your console doesn't work" isn't likely to go that far. Fix the problem on the base of this: stack consumption by host printf(). Use kernel sprintf() and os_write_file, using a wild guess that one page will be enough for the message, to preallocate the buffer with kmalloc().

setup_initial_poll is only called with sigio_lock() held, so use appropriate allocation. Also, parse_chan() can also be called when holding a spinlock (see line_open() -> parse_chan_pair()). I have sporadic problems (spinlock taken twice, with spinlock debugging on UP) which could be caused by a sequence like "take spinlock, alloc and go to sleep, take again the spinlock in the other thread".

Following i386, we should maybe refuse trying to fault in pages when we're doing atomic operations, because to handle the fault we could need to take already taken spinlocks. Also, if we're doing an atomic operation (in the sense of in_atomic()) we're surely in kernel mode and we're surely going to handle adequately the failed fault, so it's safe to behave this way. Currently, on UML SMP is rarely used, and we don't support PREEMPT, so this is unlikely to create problems right now, but it might in the future.

Things are breaking horribly with sysrq called in interrupt context. I want to try to fix it, but probably this is simpler. To tell the truth, sysrq is normally run in interrupt context, so there shouldn't be any problem. There's also a warning from the fault handler because it's run in atomic context (I have a patch for that, only I deferred it). This is why I'm doing this.

The current code doesn't handle well general protection faults on the host - it thinks that cr2 is always the address of a page fault. While actually, on general protection faults, that address is not accessible, so we'd better assume we couldn't satisfy the fault. Currently instead we think we've fixed it, so we go back, retry the instruction and fault again endlessly. This leads to the kernel hanging when doing copy_from_user(dest, -1, ...) in TT mode, since reading *(-1) causes a GFP, and we don't support kernel preemption.

I had an issue on ia64 where I got a bug in kernel/workqueue because kzalloc returned a NULL pointer due to the task structure getting too big for the slab allocator. Usually these cases are caught by the kmalloc macro in include/linux/slab.h. Compilation will fail if a too big value is passed to kmalloc. However, kzalloc uses __kmalloc which has no check for that. This patch makes __kmalloc bug if a too large entity is requested.

The SMU is the "system controller" chip used by Apple recent G5 machines including the iMac G5. It drives things like fans, i2c busses, real time clock, etc... The current kernel contains a very crude driver that doesn't do much more than reading the real time clock synchronously. This is a completely rewritten driver that provides interrupt based command queuing, a userland interface, and an i2c/smbus driver for accessing the devices hanging off the SMU i2c busses like temperature sensors. This driver is a basic block for upcoming work on thermal control for those machines, among others.

The recent iommu fix broke booting on some POWER4 and POWER5 LPAR boxes. It looks like we have been calling the non LPAR iommu_dev_setup on LPAR machines for a while. The recent iommu fix caused that code path to fail. It looks like we just need to hook up the devices iommu_table to the parents one, so do that instead of calling iommu_dev_setup_pSeries and crossing the streams.

The numa slab allocator may allocate pages from foreign nodes onto the lists for a particular node if a node runs out of memory. Inspecting the slab->nodeid field will not reflect that the page is now in use for the slabs of another node. This patch fixes that issue by adding a node field to free_block so that the caller can indicate which node currently uses a slab. Also removes the check for the current node from kmalloc_cache_node since the process may shift later to another node which may lead to an allocation on another node than intended.
