Alexandre Ghiti 1ff95eb2be riscv: Fix RISCV_ALTERNATIVE_EARLY ... RISCV_ALTERNATIVE_EARLY will issue sbi_ecall() very early in the boot process, before the first memory mapping is setup so we can't have any instrumentation happening here. In addition, when the kernel is relocatable, we must also not issue any relocation this early since they would have been patched virtually only. So, instead of disabling instrumentation for the whole kernel/sbi.c file and compiling it with -fno-pie, simply move __sbi_ecall() and __sbi_base_ecall() into their own file where this is fixed.
