Today i noticed in linux-next this commit:
commit b0d9c17503444c2df8cb8e93ccfa4877edd71933
Author: Sanjay Lal <sanjayl@xxxxxxxxxxx>
Date: Wed Nov 21 18:34:14 2012 -0800
MIPS: Export symbols used by KVM/MIPS module
which causes this kernel build warning on ia64:
WARNING: vmlinux: 'min_low_pfn' exported twice. Previous export was in vmlinux
We just need to delete the arch/ia64 specific export (and grep says
for arch/metag too):
$ git grep min_low_pfn | grep EXPORT
arch/ia64/kernel/ia64_ksyms.c:EXPORT_SYMBOL(min_low_pfn); /* defined
by bootmem.c, but not exported by generic code */
arch/metag/kernel/metag_ksyms.c:EXPORT_SYMBOL(min_low_pfn);
mm/bootmem.c:EXPORT_SYMBOL(min_low_pfn);
Can you do this in the same branch as the mips change so the bits
will flow to Linus together in the next window?
ia64 change (which gmail will no doubt mangle)
From: "Luck, Tony" <tony.luck@xxxxxxxxx>
min_low_pfn is now exported by generic code
