Re: [RFC v2 1/8] backports: disable PCI functions for kernels without PCI support

[Hauke Mehrtens]

Nice work,

what kernel version(s) without PCI support have you tested this against?

There are also PCI(e) functions in backport/compat/compat-3.7.c and
backport/compat/compat-2.6.27.c

The mainline Linux kernel uses a empty pci_wake_from_d3() function if
CONFIG_PCI is not set in include/linux/pci.h

I'm using this with kernel version 2.6.24.7

That's true but they do not break the build. The functions which are called
inside these PCI(e) functions have already empty stub functions if PCI
support is not enabled.

Indeed, I've just realized that an include of pci.h in compat-2.6.28.c is 
enough to make it work with kernel version 2.6.24. I will resend the patch with this change.
