    Cannot build kernel since 3.7.4

    Ever since 3.7.4 I have not been able to successfully build the linux kernel due to the error given at the end of this post, do any of you have suggestions on what I can do to resolve this issue?

    If it helps here's a few seemingly relevant kernel configs (which matches my current configuration for 3.7.3), if you'd like to see more let me know:
    # CONFIG_PCI is not set
    In addition to those configs, it may help for me to mention that I'm running this kernel within a Xen VPS hosted on Linode. For that these extra configs are also set, at a high level (omitting extra virt/xen configs):

    Finally, here is the build error:
      GEN     .version
      CHK     include/generated/compile.h
      UPD     include/generated/compile.h
      CC      init/version.o
      LD      init/built-in.o
    arch/x86/built-in.o: In function `setup_arch':
    (.init.text+0x2f8d): undefined reference to `early_pci_allowed'
    arch/x86/built-in.o: In function `setup_arch':
    (.init.text+0x2fa1): undefined reference to `read_pci_config_16'
    arch/x86/built-in.o: In function `setup_arch':
    (.init.text+0x2fba): undefined reference to `read_pci_config_16'
    make: *** [vmlinux] Error 1

    I can currently build and am running 3.7.3.

    While not sure why are you getting this error ... have you tried make mproper and starting from scratch without merging with make oldconfig?

    I almost always make mrproper before building, and while I do typically make oldconfig, in this instance I also have tried a make menuconfig and still ran into the issue.

    OK, the problem is that in fact PCI must now be enabled if virtualization is (or at least that seems to be the case).

    I wonder why all of a sudden PCI is required...

    Thanks anyway,
