Since 2.6.17-rc1, there is a new kernel option available for arch
x86_64:
config REORDER
bool "Function reordering"
default n
help
This option enables the toolchain to reorder functions for a more
optimal TLB usage. If you have pretty much any version of binutils,
this can increase your kernel build time by roughly one minute.
This option does the following (in arch/x86_64/Makefile)
cflags-$(CONFIG_REORDER) += -ffunction-sections
I understand that you are investigating an issue on 2.6.16, arch i386,
so this doesn't apply directly, but maybe the latest FC4 kernels use a
similar compilation flag for arch i386?
