Since commit0043ecea23("vmlinux.lds.h: Adjust symbol ordering in text output section"), the exception table in arch/openrisc/kernel/head.S is no longer positioned at the very beginning of the kernel image, which causes a boot failure. Currently, the exception table resides in the regular .text section. Previously, it was placed at the head by relying on the linker receiving arch/openrisc/kernel/head.o as the first object. However, this behavior has changed because sections like .text.{asan,unknown,unlikely,hot} now precede the regular .text section. The .head.text section is intended for entry points requiring special placement. However, in OpenRISC, this section has been misused: instead of the entry points, it contains boot code meant to be discarded after booting. This feature is typically handled by the .init.text section. This commit addresses the issue by replacing the current __HEAD marker with __INIT and re-annotating the entry points with __HEAD. Additionally, it adds __REF to entry.S to suppress the following modpost warning: WARNING: modpost: vmlinux: section mismatch in reference: _tng_kernel_start+0x70 (section: .text) -> _start (section: .init.text) Fixes:0043ecea23("vmlinux.lds.h: Adjust symbol ordering in text output section") Reported-by: Guenter Roeck <linux@roeck-us.net> Closes: https://lore.kernel.org/all/5e032233-5b65-4ad5-ac50-d2eb6c00171c@roeck-us.net/#t Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> Tested-by: Guenter Roeck <linux@roeck-us.net> Reviewed-by: Rong Xu <xur@google.com> Signed-off-by: Stafford Horne <shorne@gmail.com>

# Head objects
|
|
#
|
|
# The objects listed here are placed at the head of vmlinux. A typical use-case
|
|
# is an object that contains the entry point. This is kept for compatibility
|
|
# with head-y, which Kbuild used to support.
|
|
#
|
|
# A counter approach is to control the section placement by the linker script.
|
|
# The code marked as __HEAD goes into the ".head.text" section, which is placed
|
|
# before the normal ".text" section.
|

# If you can achieve the correct code ordering by linker script, please delete
|
