Subject[PATCH 4.9 62/88] x86/boot/compressed: Dont declare __force_order in kaslr_64.c
Date
From: H.J. Lu <hjl.tools@gmail.com>

[ Upstream commit df6d4f9db79c1a5d6f48b59db35ccd1e9ff9adfc ]

GCC 10 changed the default to -fno-common, which leads to

LD arch/x86/boot/compressed/vmlinux
ld: arch/x86/boot/compressed/pgtable_64.o:(.bss+0x0): multiple definition of `__force_order'; \
arch/x86/boot/compressed/kaslr_64.o:(.bss+0x0): first defined here
make[2]: *** [arch/x86/boot/compressed/Makefile:119: arch/x86/boot/compressed/vmlinux] Error 1

Since __force_order is already provided in pgtable_64.c, there is no
need to declare __force_order in kaslr_64.c.
