note that the code has some internal .p2align
directives that assume the entry is aligned to
some large alignment (.p2align 6 in orig code)

i think it would be better to keep the entry
aligned (but i don't know if it makes a big
difference on some existing core, it's more
for consistency with upstream).

musl normally does not align function entries
but for a few select functions it is probably
not too much overhead?
