Unconditional writing to MAS7, which doesn't exist on the e500v1 core, in a
TLB miss handler has been in the code for several years now. Since this has
gone unnoticed for so long, it's easily concluded that e500v1 is not in use
with FreeBSD. Simplify the code path a bit, by unconditionally zeroing MAS7
instead of calling a subroutine to do it.
r18 is used to hold the old PCB flags, but cpu_throw doesn't populate r18
with PCB flags, since the old thread is gone. This can lead to panics on
cores that don't have the registers guarded by these flags.
This version fixes the problems identified in r345244.

Add a note to MAINTAINERS requesting pre-commit review from the graphics

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
invalid bitmaps for the cursor, then the results may be different from
before.
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.
These predicates are vestigal and cannot be true today. For example,
idle threads are not allowed to acquire locks.
Also cache curthread in breada().

When set, we ignore all the hints that the UEFI boot manager has set
for us. We also always fail back to the OK prompt when we can't find
the right thing to boot rather than failing back to the UEFI boot
manager. This has the side effect of also expanding the cases where we
fail back to the OK prompt to include when we're booted under UEFI,
but UEFI::BootCurrent isn't set in the environment and we can't find a
proper place to boot from.

Next fetch FreeBSD-NextLoaderEnv UEFI environment variable. If

environment variable so it only happens once.
This lets one set environment variables in the bootloader.
Unfortunately, we don't have all the mechanisms in place to parse the
file, nor do we have the magic pattern matching in place that
loader.conf has. Variables are of the form foo=bar. No quotes are
supported, so spaces aren't allowed, for example. Also, variables like
foo_load=yes are intercepted when we parse the loader.conf file and
things are done based on that. Since those aren't done here, variables
that cause an action to happen won't work.

Add support to enable, save, and restore the following facilities:
* Target Address Register (bctar) -- seemingly just another register to
branch to.
* Event-based branching -- an interrupt-like userspace event handler
subsystem.
* Load-monitored facility -- A facility that allows monitoring a range of
physical memory, and triggering an event on access. Targeted to garbage
collection software features.
The Data Stream Control Register (DSCR) is privileged on POWER7, but
unprivileged (different register) on POWER8 and later. However, it's now
guarded by a new register, the Facility Status and Control Register, instead of
the MSR like other pre-existing facilities (FPU, Altivec). The FSCR must be
managed explicitly, since it's effectively an extension of the MSR.

Since the non-volatile registers are restored at the end of cpu_switchin (of
the new thread) they're free for us to use for our own purposes. Load the
PCB_FLAGS into a non-volatile register so it's preserved across the C
function calls that manage FPU and altivec state. This removes 4 loads from
each file. Might be a trivial performance improvement (~12 clock cycles per

Add map-vdisk and unmap-vdisk commands to create virtual disk interface on top of file. This will allow to use disk image from file system to load and start the kernel.
By mapping file, we create vdiskX device, the device will be listed by lsdev [-v] and can be accessed directly as ls vdisk0p1:/path or can be used as value for currdev variable.
vdisk strategy function does not use bcache as we have bcache used with backing file. vdisk can be unmapped when all consumers have closed the open files.
In first iteration we do not support the zfs images because zfs pools do keep the device open (there is no "zpool export" mechanism). Adding zfs support is relatively simple, we just need to run zfs disk probe after mapping is done.
