[ Quoting Samuel Holland: ]
This is a separate issue, but using ".option rvc" here is a bug.
It will unconditionally enable the C extension for the rest of
the file, even if the kernel is being built with CONFIG_RISCV_ISA_C=n.
[ Quoting Palmer Dabbelt: ]
We're just looking at the address of kgdb_compiled_break, so it's
fine if it ends up as a c.ebreak.
[ Quoting Alexandre Ghiti: ]
.option norvc is used to prevent the assembler from using compressed
instructions, but it's generally used when we need to ensure the
size of the instructions that are used, which is not the case here
as noted by Palmer since we only care about the address. So yes
it will work fine with C enabled :)
So let's just remove them all.
