linux: disable_nx should not be in __cpuinitdata section for X86_32

Bug Description

I noticed a section mismatch warning while building 3.2.0-20.33 for X86_32.

AR arch/x86/lib/lib.a
LD vmlinux.o
MODPOST vmlinux.o
WARNING: vmlinux.o(.text+0x187833): Section mismatch in reference from the function load_elf_binar
The function load_elf_binary() references
the variable __cpuinitdata disable_nx.
This is often because load_elf_binary lacks a __cpuinitdata
annotation or the annotation of disable_nx is wrong.

load_elf_binary() is definitely called after initialization.

This code was added by 'UBUNTU: ubuntu: nx-emu - i386: NX emulation', so
this is not an upstream problem.

UBUNTU: SAUCE: disable_nx should not be in __cpuinitdata section for X86_32

This bug was fixed in the package linux - 3.2.0-21.34

This bug is awaiting verification that the kernel for Natty in -proposed solves the problem (2.6.38-15.59). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-natty' to 'verification-done-natty'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

From the build logs, this issue seems to be sorted out. Here's the link to the old build logs, containing the warning:

- https://launchpadlibrarian.net/98586259/buildlog_ubuntu-natty-i386.linux_2.6.38-14.58_BUILDING.txt.gz

And the link to the latest build log, without the warning:

- https://launchpadlibrarian.net/103291509/buildlog_ubuntu-natty-i386.linux_2.6.38-15.59_BUILDING.txt.gz

Tagging bug as verified.
