For future use in the Linux emulation layer add a new
exec_sysvec_init_abi() method which will fill timekeep_base and
sharedpage_obj for non native abi.

Can you de-duplicate this with exec_sysvec_init()? For instance, could you make exec_sysvec_init() call into your new function?
Perhaps your function would need to take some flags. Or better, parametrize exec_sysinit_abi() so that you can use it instead of make practically a copy.

| 327–335 | Why do you need to check this condition? The assert on the previous line verified that the condition is true. | |

| 321–325 | Add {} around then statement, it is multi-line. | |
| 355–356 | This one should be conditional on ABI_FREEBSD as well, perhaps? | |
| 401 | Should sv->sv_shared_page_obj == 0 (NULL BTW?) and sv->sv_shared_page_base != 0 asserts moved to exec_sysvec_init() ? | |
| 405 | Now, with the changes to exec_sysvec_init(), what is the reason to have exec_sysvec_init_abi()? It only asserts some state. | |

| 315 | I think that this assert (sv_shared_page_base != 0) should be only done if SV_SHP flag is set. | |

| 356 | This can be written as a single check ((flags & (SV_ABI_MASK | SV_RNG_SEED_VER) ) == (SV_ABI_FREEBSD | SV_RNG_SEED_VER)) but it is up to you. | |
