Name: riscv: alternative: Statically compute alternative section boundaries and patch compat vDSO
URL: https://patchwork.kernel.org/project/linux-riscv/list/?series=1118739
Version: 1

Currently the alternative sections are extracted from the vDSO binaries at runtime. This has runtime overhead and also doesn't work for the compat vDSO. Extract the offsets of the alternative section during the build with the existing symbol extraction machinery. Also add dummy symbols as fallback.

Currently the alternative sections are extracted from the vDSO binaries at runtime. This has runtime overhead and also doesn't work for the compat vDSO. Use the offsets generated during the build instead, fixing both issues. Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Signed-off-by: Linux RISC-V bot <linux.riscv.bot@gmail.com>

The vDSO for compat processes can also contain alternative entries. Patch those, too. Signed-off-by: Thomas Weißschuh <thomas.weissschuh@linutronix.de> Signed-off-by: Linux RISC-V bot <linux.riscv.bot@gmail.com>
