The dynamic pci id logic has been bothering me for a while, and now that I started to look into how to move some of this to the driver core, I thought it was time to clean it all up. It ends up making the code smaller, and easier to follow, and fixes a few bugs at the same time (dynamic ids were not being matched everywhere, and so could be missed on some call paths for new devices, semaphore not needed to be grabbed when adding a new id and calling the driver core, etc.) I also renamed the function pci_match_device() to pci_match_id() as that's what it really does.

- Add sanity check for io[port,mem]_resource in setup-bus.c. These resources look like "free" as they have no parents, but obviously we must not touch them. - In i386.c:pci_allocate_bus_resources(), if a bridge resource cannot be allocated for some reason, then clear its flags. This prevents any child allocations in this range, so the setup-bus code will work with a clean resource sub-tree. - i386.c:pcibios_enable_resources() doesn't enable bridges, as it checks only resources 0-5, which looks like a clear bug to me. I suspect it might break hotplug as well in some cases. From: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Signed-off-by: -

With the number of PCI bus resources increased to 8, we can handle the subtractive decode PCI-PCI bridge like a normal bridge, taking into account standard PCI-PCI bridge windows (resources 0-2). This helps to avoid problems with peer-to-peer DMA behind such bridges, poor performance for MMIO ranges outside bridge windows and prefetchable vs. non-prefetchable memory issues. To reflect the fact that such bridges do forward all addresses to the secondary bus (transparency), remaining bus resources 3-7 are linked to resources 0-4 of the primary bus. These resources will be used as fallback by resource management code if allocation from standard bridge windows fails for some reason. Signed-off-by:

This patch increases the number of resource pointers in the pci_bus structure. This is needed to store >4 resource ranges for host bridges and transparent PCI bridges. With this change, all PCI buses will have more resource pointers, but most PCI buses will only use the first 3 or 4, the remaining being NULL. The PCI core already deals with this correctly.

As usual, the reason of this breakage is quite silly: in do_entIF, we are checking for PS == 0 to see whether it was a kernel BUG() or userspace trap. It works, unless BUG() happens in interrupt - PS is not 0 in kernel mode due to non-zero IPL, and the things get messed up horribly then. In this particular case it was BUG_ON(!irqs_disabled()) triggered in run_posix_cpu_timers(), so we ended up shooting "current" with the bursts of one SIGTRAP and three SIGILLs on every timer tick. ;-)

Patch from Catalin Marinas The new EABI gcc adds -mthumb-interwork by default, even if -mabi=apcs-gnu is passed. This causes a warning for every compiled C file when -march=armv4 is used. The patch adds -mno-thumb-interwork if the option is supported. This is also useful since we don't need any ARM/Thumb interworking in the kernel Signed-off-by:

On system boot up, there was an failure reported to boot.msg: <5>Trying to move old root to /initrd ... failed According to initrd(4) man page, step #7 of BOOT-UP OPERATION is described as below: 7. If the normal root file has directory /initrd, device /dev/ram0 is moved from / to /initrd. Otherwise if directory /initrd does not exist device /dev/ram0 is unmounted. We got service calls from customers concerning about this failure message at boot time. Many systems do not have /initrd and thus the message can be changed in the case of non-existing /initrd so that it does not sound like a failure of the system.

Currently selinux_sb_copy_data requires an entire page be allocated to *orig when the function is called. This "requirement" is based on the fact that we call copy_page(in_save, nosec_save) and in_save = orig when the data is not FS_BINARY_MOUNTDATA. This means that if a caller were to call do_kern_mount with only about 10 bytes of options, they would get passed here and then we would corrupt PAGE_SIZE - 10 bytes of memory (with all zeros.) Currently it appears all in kernel FS's use one page of data so this has not been a problem. An out of kernel FS did just what is described above and it would almost always panic shortly after they tried to mount. From looking else where in the kernel it is obvious that this string of data must always be null terminated. (See example in do_mount where it always zeros the last byte.) Thus I suggest we use strcpy in place of copy_page. In this way we make sure the amount we copy is always less than or equal to the amount we received and since do_mount is zeroing the last byte this should be safe for all. Signed-off-by:
