linux-next: build failure after merge of the final tree (pci tree related)

linux-next: build failure after merge of the final tree (pci tree related)

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1375 bytes --]

Hi all,

After merging the final tree, today's linux-next build (sparc64 defconfig)
failed like this:

arch/sparc/kernel/pci.c: In function 'pci_scan_one_pbm':
arch/sparc/kernel/pci.c:689:21: error: 'struct pci_pbm_info' has no member named 'pci_last_busn'

Caused by commit 2c7f691b032b ("sparc/PCI: register busn_res for root buses").

I have added the following patch for today:

Thanks, I folded this typo fix into the relevant patch.  I'll rebase
"next" today.  Sorry for the trouble.

I am not sure what you have done, but now you have a set of duplicated
commits in your tree including both versions of the one that caused the
build failure.

This is because of my inept git usage.  I think my "next" branch ended
up with the right bits in it, but the history looked strange because I
fixed the typo in the Yinghai branch, but had a second branch that
depended on the original unfixed branch.

I rebuilt my "next" branch again and I think it's more
straightforward.  And I learned a tiny bit more about git, so thanks
for pointing this out.

Thanks, just applied it (by hand) to the linux-next branch.  Hopefully
I didn't botch it...

Sigh, I'm sorry.  Attached are the incremental patch to fix this, and
an updated version of the original patch.  I'm not git-smart enough to
push it this time (the box where I normally do that is down at the

    ia64/PCI: convert to pci_create_root_bus() for correct root bus resources
    
    Convert from pci_create_bus() to pci_create_root_bus().  This way the root
    bus resources are correct immediately.  This fixes the problem of "early"
    and "header" quirks seeing incorrect root bus resources.
    
    We can't use pci_scan_root_bus() because, like x86, ACPI hotplug currently
    requires pci_bus_add_devices() in a separate host bridge .start() method.

Well, I only have time to do a couple of arches by hand during the day,
but overnight we build almost all arches - see

Thanks for doing that, sorry for the trouble.  I don't have a set of
cross-compilers, unfortunately, but I will inspect the rest manually.
Do we have to discover problems one-by-one, or can you tell us about
any other arch build problems at the same time?

linux-next: build failure after merge of the final tree (pci tree related)

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 1602 bytes --]

Hi all,

After merging the final tree, today's linux-next build (sparc64 defconfig)
failed like this:

arch/sparc/kernel/pci.c: In function 'pci_scan_one_pbm':
arch/sparc/kernel/pci.c:697:7: error: incompatible type for argument 5 of 'pci_create_root_bus'
include/linux/pci.h:665:17: note: expected 'struct list_head *' but argument is of type 'struct list_head'

Caused by commit fa3cec8aff53 ("sparc/PCI: convert to pci_create_root_bus
()"). Same typo as for the powerpc tree. :-(  Please double check the
rest of those changes, please.

I applied the following patch for today.
