Subject: [PATCH 2/2] section garbage collection for i386

Hi Sam,

This patch adds module linker script (completely analogous to x86_64),
and "minimally" fixes vmlinux linker script by adding KEEPs.
It also deleted an outdated comment and amends help text.

I got a few "section mismatch" warnings with .config which doesn't
show them (IIRC) on original kernel.

I took a look and I think that original kernel was actually in error
and these warnings are correct!

WARNING: vmlinux.o(.text.kmem_cache_create+0x32f): Section mismatch: reference to .init.refok.text:setup_cpu_cache (after 'kmem_cache_create')
WARNING: vmlinux.o(.text.vgacon_startup+0x2dd): Section mismatch: reference to .init.refok.text:vgacon_scrollback_startup (after 'vgacon_startup')
WARNING: vmlinux.o(.data.smp_ops+0x0): Section mismatch: reference to .init.text:native_smp_prepare_boot_cpu (after 'smp_ops')
WARNING: vmlinux.o(.data.smp_ops+0x4): Section mismatch: reference to .init.text:native_smp_prepare_cpus (after 'smp_ops')
WARNING: vmlinux.o(.data.smp_ops+0xc): Section mismatch: reference to .init.text:native_smp_cpus_done (after 'smp_ops')
WARNING: vmlinux.o(.data.vesafb_driver+0x0): Section mismatch: reference to .init.text:vesafb_probe (after 'vesafb_driver')
WARNING: vmlinux.o(.data.serial8250_console+0x20): Section mismatch: reference to .init.text:serial8250_console_setup (after 'serial8250_console')
WARNING: vmlinux.o(.data.dgrs_pci_driver+0x10): Section mismatch: reference to .init.text:dgrs_pci_probe (after 'dgrs_pci_driver')

Risk of this patch is analogous to last patch of first series -
run-tested and looks safe, but needs to go into -mm first.
