With the special case handling for Blackfin and Metag was removed by
commit 94e58e0ac3 ("export.h: remove code for prefixing symbols with
underscore"), VMLINUX_SYMBOL() is no-op.
Replace the remaining usages, then remove the definition of
VMLINUX_SYMBOL() and VMLINUX_SYMBOL_STR().

initramfs_data includes the compressed binary that is the
|
|
filesystem used for early user space.
|
|
Note: Older versions of "as" (prior to binutils 2.11.90.0.23
|
|
released on 2001-07-14) dit not support .incbin.
|
|
If you are forced to use older binutils than that then the
|
|
following trick can be applied to create the resulting binary:
|
|
|
|
|
|
ld -m elf_i386 --format binary --oformat elf32-i386 -r \
|
|
-T initramfs_data.scr initramfs_data.cpio.gz -o initramfs_data.o
|
|
ld -m elf_i386 -r -o built-in.a initramfs_data.o
|
|
|
|
For including the .init.ramfs sections, see include/asm-generic/vmlinux.lds.
|
|
|
|
The above example is for i386 - the parameters vary from architectures.
|
|
Eventually look up LDFLAGS_BLOB in an older version of the
|
|
arch/$(ARCH)/Makefile to see the flags used before .incbin was introduced.
|
|
|
|
Using .incbin has the advantage over ld that the correct flags are set
|
|
in the ELF header, as required by certain architectures.
