[patch 2/6] hugetlb: Fix section mismatches

[Jeff Mahoney]

[-- Attachment #1: patches.rpmify/hugetlbfs-fix-section-mismatches --]
[-- Type: text/plain, Size: 1048 bytes --]

 hugetlb_register_node calls hugetlb_sysfs_add_hstate, which is marked with
 __init. Since hugetlb_register_node is only called by
 hugetlb_register_all_nodes, which in turn is only called by hugetlb_init,
 it's safe to mark both of them as __init.

This is wrong, you want to move hugetlb_register_all_nodes() to 
.init.text, not hugetlb_unregister_all_nodes().

Yep. You're right. I had this correct in my initial version of the patch
but accidentally deleted it while renaming them. I'll re-send.

Actually, hugetlb_register_node() also called, via a function pointer
that hugetlb registers with the sysfs node driver, when a node is hot
plugged.  So, I think the correct approach is to remove the '__init'
from hugetlb_sysfs_add_hstate() as this is also used at runtime.  I
missed this in the original submittal.

[patch 4/6] acpi: Fix section mismatch

[Jeff Mahoney]

[-- Attachment #1: patches.rpmify/acpi-fix-section-mismatch --]
[-- Type: text/plain, Size: 617 bytes --]

 acpi_early_processor_set_pdc uses processor_idle_dmi_table, which is
 marked __cpuinitdata. It's only called by acpi_bus_init, which is __init.
 We mark it __cpuinit.

Tony Luck already sent a patch for this to Len Brown (which I
acked).

Thanks,

[patch 6/6] virtio: fix section mismatch warnings

[Jeff Mahoney]

[-- Attachment #1: patches.rpmify/virtio-fix-section-mismatch-warnings --]
[-- Type: text/plain, Size: 2164 bytes --]

 This patch fixes the following warnings by renaming the driver structures
 to be suffixed with _driver.

 WARNING: drivers/virtio/virtio_balloon.o(.data+0x88): Section mismatch in reference from the variable virtio_balloon to the function .devexit.text:virtballoon_remove()

 WARNING: drivers/char/hw_random/virtio-rng.o(.data+0x88): Section mismatch in reference from the variable virtio_rng to the function .devexit.text:virtrng_remove()

umm, sure.  But I wish I knew how the patch worked.  Is there some
magic sauce which moves a variable called foo_driver into a different
section or what?

And if so, what was I doing when that got done :(

It doesn't move it into a different section, it just shuts the warning
up. modpost has a whitelist it uses to ignore the mismatch warning.
