[PATCH 0/4] riscv: alternative: Also patch the CFI vDSO

Posted by Thomas Weißschuh 1 month, 1 week ago

The dedicated vDSO for CFI-enabled userspace can also contain
alternative entries.

It seems the vDSO alternative patching is actually dead code since
commit 0b1d60d6dd9e ("riscv: Fix build with
CONFIG_CC_OPTIMIZE_FOR_SIZE=y"). However new usages will be added 
soonish.
