25e37f3b97 In addition to the spinlock, use the lockmgr() to serialize access to
the back-end page allocator. This allows the back-end to sleep since we
now relinquish the spin lock after acquiring the long-term lock.

f1f6ec6afe Add an alternate pool page allocator that can be used if the pool is
never accessed in interrupt context.  In the UVM case, this uses the
kernel_map, to reduce usage of the previous kmem_map resource.

275d1554aa Abolition of bcopy, ovbcopy, bcmp, and bzero, phase one.
bcopy(x, y, z) ->  memcpy(y, x, z)
ovbcopy(x, y, z) -> memmove(y, x, z)
   bcmp(x, y, z) ->  memcmp(x, y, z)
  bzero(x, y)    ->  memset(x, 0, y)

7c61b8cdd8 Instrument "idle pages" (i.e. pages which have no items allocated from
them, and could thus be freed back to the system).

fe7696eacb Un-static pool_head; vmstat wants to find it. 1998-07-31 21:55:09 +00:00

fc4828b0b4 A few small changes to how pool pages are allocated/freed:
- If either an alloc or release function is provided, make sure both are
  provided, otherwise panic, as this is a fatal error.
- If using the default allocator, default the pool pagesz to PAGE_SIZE,
  since that is the granularity of the default allocator's mechanism.
- In the default allocator, use new functions:
	uvm_km_alloc_poolpage()/uvm_km_free_poolpage(), or
	kmem_alloc_poolpage()/kmem_free_poolpage()
  rather than doing it here.  These functions may use pmap hooks to
  provide alternate methods of mapping pool pages.
