I'm guessing this is in sev-shared.c because it is going to be used by
both stages?

State what this is:
/* Bitmap of SEV features supported by the hypervisor */
> +static u64 hv_features __section(".data");
Also, I'm assuming that bitmap remains immutable during the guest
lifetime so you can do:
static u64 hv_features __ro_after_init;
instead, which will do:
static u64 hv_features __attribute__((__section__(".data..ro_after_init")));
and it'll be in the data section and then also marked read-only after
init, after mark_rodata_ro() more specifically.
Thx.
