* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6: PCI: clear bridge resource range if BIOS assigned bad one PCI: hotplug/cpqphp, fix NULL dereference Revert "PCI: create function symlinks in /sys/bus/pci/slots/N/" PCI: change resource collision messages from KERN_ERR to KERN_INFO
-

Yannick found that video does not work with 2.6.34. The cause of this bug was that the BIOS had assigned the wrong range to the PCI bridge above the video device. Before 2.6.34 the kernel would have shrunk the size of the bridge window, but since d65245c3 PCI: don't shrink bridge resources the kernel will avoid shrinking BIOS ranges. So zero out the old range if we fail to claim it at boot time; this will cause us to allocate a new range at startup, restoring the 2.6.34 behavior. Fixes regression https://bugzilla.kernel.org/show_bug.cgi?id=16009. Reported-by:

There are devices out there which are PCI Hot-plug controllers with compaq PCI IDs, but are not bridges, hence have pdev->subordinate NULL. But cpqphp expects the pointer to be non-NULL. Add a check to the probe function to avoid oopses like: BUG: unable to handle kernel NULL pointer dereference at 00000050 IP: [<f82e3c41>] cpqhpc_probe+0x951/0x1120 [cpqphp] *pdpt = 0000000033779001 *pde = 0000000000000000 ... The device here was: 00:0b.0 PCI Hot-plug controller [0804]: Compaq Computer Corporation PCI Hotplug Controller [0e11:a0f7] (rev 11) Subsystem: Compaq Computer Corporation Device [0e11:a2f8] Signed-off-by:

We can often deal with PCI resource issues by moving devices around. In that case, there's no point in alarming the user with messages like these. There are many bug reports where the message itself is the only problem, e.g., https://bugs.launchpad.net/ubuntu/+source/linux/+bug/413419 . Signed-off-by:

If we have enough memory to allocate a new cap release message, do so, so that we can send a partial release message immediately. This keeps us from making the MDS wait when the cap release it needs is in a partially full release message. If we fail because of ENOMEM, oh well, they'll just have to wait a bit longer.

cb->atapi.cdb is an array of 16 u8 elements. The call too memset() would set the first part of the sge array to zero as well. It's not a packed struct. This one has been around for five years. I found it with Smatch. I think the reason no one has seen it before is because we normally call sil24_fill_sg() and that overwrites sge with proper information? Signed-off-by:

As it stands this check compares the number of pages to the page size. This makes no sense and makes the fcntl fail in almost any sane case. Fix it by checking if nr_pages is not zero (it can become zero only if arg is too big and round_pipe_size() overflows). Signed-off-by:

I don't like the subtle multi-context code in bd_claim (ie. detects where it has been called based on bd_claiming). It seems clearer to just require a new function to finish a 2-part claim. Also improve commentary in bd_start_claiming as to how it should be used. Signed-off-by:

David Howells authored
Reinstate the null behaviour that the in-kernel gdbstub had for the GDB remote protocol 'p' command (retrieve a single register value) prior to commit 7ca8b9c0 ("frv: extend gdbstub to support more features of gdb"). Before that, the 'p' command just returned an empty reply, which causes gdb to then go and use the 'g' command. However, since that commit, the 'p' command returns an error string, which causes gdb to abort its connection to the target. Not all gdb versions are affected, some use try 'g' first, and if that works, don't bother with 'p', and so don't see the error. Signed-off-by:

10, 233 is allocated officially to /dev/kmview which is shipping in Ubuntu and Debian distributions. vhost_net seem to have borrowed it without making a proper request and this causes regressions in the other distributions. vhost_net can use a dynamic minor so use that instead.

If cr0.wp=0, we have to allow the guest kernel access to a page with pte.w=0. We do that by setting spte.w=1, since the host cr0.wp must remain set so the host can write protect pages. Once we allow write access, we must remove user access otherwise we mistakenly allow the user to write the page. Reviewed-by:

Always invalidate spte and flush TLBs when changing page size, to make sure different sized translations for the same address are never cached in a CPU's TLB. Currently the only case where this occurs is when a non-leaf spte pointer is overwritten by a leaf, large spte entry. This can happen after dirty logging is disabled on a memslot, for example.
