 	src/sys/uvm: uvm_map.c
 
 Log Message:
 PR kern/54395
 
 - Align hint for virtual address at the beginning of uvm_map() if
   required. Otherwise, it will be rounded up/down in an unexpected
   way by uvm_map_space_avail(), which results in assertion failure.
 
   Fix kernel panic when executing earm binary (8KB pages) on aarch64
   (4KB pages), which relies on mmap(2) with MAP_ALIGNED flag.
 
 - Use inline functions/macros consistently.
 
 - Add some more KASSERT's.
