[PULL 5/6] softmmu/physmem: Remove the ifdef __linux__ around the pagesize functions

[Thomas Huth]

Now that host_memory_backend_pagesize() is not depending on the hugetlb
memory path handling anymore, we can also remove the #ifdef and the
TOCTTOU comment from the calling functions - the code should now work
equally well on all host architectures.
