62dd3c74c0 powerpc: Drop OPAL_HANDLE_HMI2 for now, to avoid panicking
It's possible for a Hypervisor Maintenance Interrupt (HMI) to occur while in
the pmap code, holding locks.  This can cause WITNESS to panic due to lock
errors in calling pmap_kextract().  Since we don't yet handle the flags
returned by OPAL_HANDLE_HMI2, just stop using it, so that we don't call into
pmap_kextract().

f79fcaf038 Fix another race between vm_map_protect() and vm_map_wire().
vm_map_wire() increments entry->wire_count, after that it drops the
map lock both for faulting in the entry' pages, and for marking next
entry in the requested region as IN_TRANSITION. Only after all entries
are faulted in, MAP_ENTRY_USER_WIRE flag is set.

This makes it possible for vm_map_protect() to run while other entry'
MAP_ENTRY_IN_TRANSITION flag is handled, and vm_map_busy() lock does
not prevent it. In particular, if the call to vm_map_protect() adds
VM_PROT_WRITE to CoW entry, it would fail to call
vm_fault_copy_entry(). There are at least two consequences of the
race: the top object in the shadow chain is not populated with
writeable pages, and second, the entry eventually get contradictory
flags MAP_ENTRY_NEEDS_COPY | MAP_ENTRY_USER_WIRED with VM_PROT_WRITE
set.

Handle it by waiting for all MAP_ENTRY_IN_TRANSITION flags to go away
in vm_map_protect(), which does not drop map lock afterwards. Note
that vm_map_busy_wait() is left as is.

5ed15f8bbd Support all reasonable cursor sizes. Reduce the size of the standard
cursor from 16x16 (with 6 columns unused) to 10x16 and rename it to
the "small" cursor.  Add a "large" 19x32 cursor and use it for screen
widths larger than 800 pixels.  Use libvgl's too-small indentation for
the large data declarations.

MOUSE_IMG_SIZE = 16 is still part of the API.  If an application supplies

28164a5b31 Refactor and simplify hiding the mouse cursor and fix bugs caused by
complications in the previous methods.

r346761 broke showing the mouse cursor after changing its state from
off to on (including initially), since showing the cursor uses the
state to decide whether to actually show and the state variable was
not changed until after null showing.  Moving the mouse or copying
under the cursor fixed the problem.  Fix this and similar problems for
the on to off transition by changing the state variable before drawing
the cursor.

r346641 failed to turn off the mouse cursor on exit from vgl.  It hid
the cursor only temporarily for clearing.  This doesn't change the state
variable, so unhiding the cursor after clearing restored the cursor if its
state was on.  Fix this by changing its state to VGL_MOUSEHIDE using the
application API for changing the state.

Remove the VGLMouseVisible state variable and the extra states given by it.
This was an optimization that was just an obfuscation in at least the
previous version.

Staticize VGLMouseAction().  Remove VGLMousePointerShow/Hide() except as
internals in __VGLMouseMode().  __VGLMouseMouseMode() is the same as the
application API VGLMouseMouseMode() except it returns the previous mode
which callers need to know to restore it after hiding the cursor.

Use the refactoring to make minor improvements in a simpler way than was
possible:
- in VGLMouseAction(), only hide and and unhide the mouse cursor if the
  mouse moved
- in VGLClear(), only hide and and unhide the mouse cursor if the clearing
  method would otherwise clear the cursor.
