Subject: [PATCH] x86: Don't declare __force_order in kaslr_64.c
|
|
|
|
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.
