Review Comment:
Try test with mm_pgalloc(MM_NPAGES(tablesize)); cannot pass the knsh &
knsh_smp `hello` test, maybe we should replace as a optimize in further commit?
also if
```C
for(){mm_pgalloc(1)}
```
possible problem when get mmu table not contiguous,
or problem when use mm_pgalloc larger than 1. should spend more time on this
topic later
