SVN rev 218494 on 2011-02-09 19:08:21Z by marcel
Provide convenience function for obtaining MODINFO_ADDR and MODINFO_SIZE
attributes for preloaded modules/images. In particular, MODINFO_ADDR has
the added complexity of not always being relocated properly. Rather than
kluging this in the various components that are affected, we handle it
in a centralized place (preload_fetch_addr()). To that end, expose a new
variable, preload_addr_relocate, that MD initialization code can set and
that turns the address attribute into a valid kernel VA.
Architectures that need the relocation: arm & powerpc (at least).
Components that can utilize this: acpi(4), md(4), fb(4), pci(4), ZFS, geli.
