Here is what I wrote:
In drivers/firmware/arm_scmi/perf.c iowrite64_hi_lo() is called directly.
So, I could add this function to arch/parisc/lib/iomap.c to prevent the linker error.
But this file is compiled on parisc just because CONFIG_COMPILE_TEST is set, while
in production builds it would never be compiled.
So, what's the usual take in such a scenario?
Shall I ignore this linker error and 0-day warning, or shall I add a workaround?
In general I'd prefer this patch:
