89f6b8632c Switch the vm_object mutex to be a rwlock. This will enable in the
future further optimizations where the vm_object lock will be held
in read mode most of the time the page cache resident pool of pages
are accessed for reading purposes.

The change is mostly mechanical but few notes are reported:
* The KPI changes as follow:
  - VM_OBJECT_LOCK() -> VM_OBJECT_WLOCK()
  - VM_OBJECT_TRYLOCK() -> VM_OBJECT_TRYWLOCK()
  - VM_OBJECT_UNLOCK() -> VM_OBJECT_WUNLOCK()
  - VM_OBJECT_LOCK_ASSERT(MA_OWNED) -> VM_OBJECT_ASSERT_WLOCKED()
    (in order to avoid visibility of implementation details)
  - The read-mode operations are added:
    VM_OBJECT_RLOCK(), VM_OBJECT_TRYRLOCK(), VM_OBJECT_RUNLOCK(),
    VM_OBJECT_ASSERT_RLOCKED(), VM_OBJECT_ASSERT_LOCKED()
* The vm/vm_pager.h namespace pollution avoidance (forcing requiring
  sys/mutex.h in consumers directly to cater its inlining functions
  using VM_OBJECT_LOCK()) imposes that all the vm/vm_pager.h
  consumers now must include also sys/rwlock.h.
* zfs requires a quite convoluted fix to include FreeBSD rwlocks into
  the compat layer because the name clash between FreeBSD and solaris
  versions must be avoided.
  At this purpose zfs redefines the vm_object locking functions
  directly, isolating the FreeBSD components in specific compat stubs.

The KPI results heavilly broken by this commit.  Thirdy part ports must
be updated accordingly (I can think off-hand of VirtualBox, for example).

fdc5dd2d2f MFcalloutng:
Switch eventtimers(9) from using struct bintime to sbintime_t.
Even before this not a single driver really supported full dynamic range of
struct bintime even in theory, not speaking about practical inexpediency.
This change legitimates the status quo and cleans up the code.

dd0b4fb6d5 Reform the busdma API so that new types may be added without modifying
every architecture's busdma_machdep.c.  It is done by unifying the
bus_dmamap_load_buffer() routines so that they may be called from MI
code.  The MD busdma is then given a chance to do any final processing
in the complete() callback.

The cam changes unify the bus_dmamap_load* handling in cam drivers.

The arm and mips implementations are updated to track virtual
addresses for sync().  Previously this was done in a type specific
way.  Now it is done in a generic way by recording the list of
virtuals in the map.

9f499cc5ae Little-endian and other fixes for Broadcom XLP network driver
The changes are:
 - the microcore code loaded into the NAE has to be byteswapped
   in LE
 - the descriptors in memory for a P2P NAE descriptor has to be
   byteswapped in LE
 - the m_data pointer is already cacheline aligned, so the
   unnecessary m_adj to cacheline size can be removed
 - fix mask used to obtain physical address from the Tx freeback
   descriptor
 - fix a compile error in code under #ifdef

fa12b7f6e0 Define VM_KMEM_SIZE_MAX as a fraction of the kernel address space size
rather than a constant so that VM_KMEM_SIZE_MAX will scale automatically
with the kernel address space size.  This is particularly important for
MIPS because the same definition is used by both 32- and 64-bit kernels.

c36a1b5c66 Merge Perforce changeset 219925 to head:
Provided a bus_space implementation for FDT, modelled on
  bus_space_generic, but with a local version of the map address
  routine that does a P->V translation, as is the case with NLM's
  similar routine for XLP.  It's not clear to me that this is the
  right solution -- possibly this belongs in simplebus -- however,
  it is sufficient to get the DE4 LED driver working.

0fe7f25666 Merge Perforce chance 219924 to head:
In a sign of weakness, replicate the MIPS bus_space_generic.c to
  produce a new FDT version, which will perform necessary address
  space translation for bus_space -- the solution used in NLM's MIPS
  FDT support, but possibly not quite the right thing.  This is
  inconsistent with regular I/O via the nexus and the generic
  bus_space, which instead perform translation via pmap_mapdev()
  when a resource is activated.  However, it will work while I
  attempt to identify what the right way to reconcile possible
  approaches.

  (Another approach might be to make simplebus use Nexus's activate
  routine instead of a generic one?)

b32ecf44bc Flip the semantic of M_NOWAIT to only require the allocation to not
sleep, and perform the page allocations with VM_ALLOC_SYSTEM
class. Previously, the allocation was also allowed to completely drain
the reserve of the free pages, being translated to VM_ALLOC_INTERRUPT
request class for vm_page_alloc() and similar functions.

Allow the caller of malloc* to request the 'deep drain' semantic by
providing M_USE_RESERVE flag, now translated to VM_ALLOC_INTERRUPT
class. Previously, it resulted in less aggressive VM_ALLOC_SYSTEM
allocation class.

Centralize the translation of the M_* malloc(9) flags in the single
inline function malloc2vm_flags().

6961891ea1 The function pmap_alloc_direct_page() unconditionally zeroes the returned
page.  Therefore, it is really inappropriate for use by the function
uma_small_alloc().  The effect of using it was that every page was zeroed
at least once and possibly twice if M_ZERO was passed as a "wait" flag.
