Hi,
few days ago I reenabled building EISA support in my kernel,
and because of SECTION_MISMATCH logic, I got warning.
And i discovered this
...
LD drivers/eisa/built-in.o
WARNING: drivers/eisa/built-in.o(.data+0xd0): Section mismatch in reference from the variable pci_eisa_driver to the function .init.text:pci_eisa_init()
The variable pci_eisa_driver references
the function __init pci_eisa_init() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
...

It looks that pretty old commit

[PATCH] drivers/eisa/pci_eisa.c:pci_eisa_init() should be init
introduced this warning.
There was some time ago a patch for solving this problem,
http://www.spinics.net/lists/linux-pci/msg09638.html
but It looks this patch adding __initdata or __refdata
was somehow forgotten and didn't land in mainline.
PS. There was some gossips about removing ISA support from Linux.
Please do not do this. There is still lots of
cards and computers with it. I for example have 3 workstations
(two being Alpha and one being PC), each having important
ISA hardware (ok. one is sound card - good one,
but other have measurmnt hardware used in scientific experiments).
Even my Laptop have some ISA hardware like thermal monitoring.
However removing MCA and VLB could make some sense. Some.

Witek
