[PATCH 5.10 042/101] riscv32: Use medany C model for modules

From: Sasha Levin
Date: Mon Jun 28 2021 - 10:33:07 EST


From: Khem Raj <raj.khem@xxxxxxxxx>

[ Upstream commit 5d2388dbf84adebeb6d9742164be8d32728e4269 ]

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
