[permalink] [raw]
Subject: [PATCH] move some .pci_fixup_* sections into .init

.pci_fixup_final is only used from .init.text, and hence can (along
with the respective handler functions) reside in .init.*.

Several other .pci_fixup_* sections are needed only during boot and
suspend/resume, and can therefore be moved into .init.* if
!CONFIG_PM_OPS.

While generally section mismatch checking is being turned on by this
patch for all of .pci_fixup_*, for .pci_fixup_header it is being
suppressed for the moment as it caused way too much fallout.
Theoretically, all respective handlers must get their __init/__devinit
removed, as this gets processed from a non-__init, non-__devinit
function.

This also adds a previously missing comma in the definition of
ALL_INIT_DATA_SECTIONS.
