When CONFIG_CMODEL_MEDLOW is used it ends up generating riscv_hi20_rela relocations in modules which are not resolved during runtime and following errors would be seen [ 4.802714] virtio_input: target 00000000c1539090 can not be addressed by the 32-bit offset from PC = 39148b7b [ 4.854800] virtio_input: target 00000000c1539090 can not be addressed by the 32-bit offset from PC = 9774456d Signed-off-by: Khem Raj <raj.khem@gmail.com> Cc: Paul Walmsley <paul.walmsley@sifive.com> Cc: Palmer Dabbelt <palmer@dabbelt.com> Cc: Albert Ou <aou@eecs.berkeley.edu> --- arch/riscv/Makefile | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
