Add Makefile snippet to ease porting NetBSD testcases to FreeBSD from
contrib/netbsd-tests
This Makefile snippet handles polluting testcases with -lnetbsd, specific
headers for ATF version differences, and does necessary rewriting for the
testcases to match the format discussed on the TestSuite wiki page
(t_<foo> -> <foo>_test)
One must define SRCTOP (inspired by projects/bmake), OBJTOP, and TESTSRC
(e.g. contrib/netbsd-tests/lib/libc/gen) to use the Makefile snippet
Test programs are specific either via NETBSD_ATF_TESTS_C or NETBSD_ATF_TESTS_SH
C++ analogs aren't currently implemented.
The imported testcases will be cleaned up to use this Makefile snippet pseudo
"API".

agp_intel.c provides support for AGP on Intel chipsets from 440/BX to
875. This intersects with the agp_i810.c, which supports all Intels
from i810 to Core i5/7. Both agp_intel.c and agp_i810.c are compiled
into kernel when device agp is specified in config, and agp_i810
attach seems to be selected by chance due to linking order.
Strip support for 810 and later from agp_intel.c. Since 440-class
chipsets do not support any long-mode capable CPUs, remove agp_intel.c
from amd64 kernel file list. Note that agp_intel.c is not compiled
into agp.ko on amd64 already.

By default, vt(4) gets the "preferred mode" from DRM, when using a DRM
video driver as its backend. The preferred mode is usually the native
screen resolution.
Now, if this mode isn't appropriate, a user can use loader tunables to
select a mode. The tunables are read in the following order:
1. kern.vt.fb.modes.$connector_name
2. kern.vt.fb.default_mode
For example, to set a 1024x768 mode, no matter the connector:
kern.vt.fb.default_mode="1024x768"
To set a 800x600 mode only on the laptop builtin screen:
kern.vt.fb.modes.LVDS-1="800x600"

MFamd64: Add support for extended FPU states on i386. This includes
support for AVX on i386.
- Similar to amd64, move the FPU save area out of the PCB and instead
store saved FPU state in a variable-sized buffer after the PCB on the
stack.
- To support the variable PCB location, alter the locore code to only use
the bottom-most page of proc0stack for init386(). init386() returns
the correct stack pointer to locore which adjusts the stack for thread0
before calling mi_startup().
- Don't bother setting cr3 in thread0's pcb in locore before calling
init386(). It wasn't used (init386() overwrote it at the end) and
it doesn't work with the variable-sized FPU save area.
- Remove the new-bus attachment from npx. This was only ever useful for
external co-processors using IRQ13, but those have not been supported
for several years. npxinit() is now called much earlier during boot
(init386()) similar to amd64.
- Implement PT_{GET,SET}XSTATE and I386_GET_XFPUSTATE.
- npxsave() is now only called from context switch contexts so it can
use XSAVEOPT.

vt(4): Fix keyboard allocation when kbdmux(4) isn't used
The problem was that only the kbdmux keyboard index was saved in
vd->vd_keyboard. This index is -1 when kbdmux isn't used. In this
case, the keyboard was correctly allocated, but the returned index was
discarded.
When non-forced unmount or remount rw->ro is performed, writes on UFS
are not suspended. In particular, on the SU-enabled vulumes, there is
no reason why, between the call to softdep_flushfiles() and
softdep_waitidle(), SU work items cannot be queued.
Correct the condition to trigger the panic by only checking when
forced operation is done. Convert direct panic() call into KASSERT(),
there is no invalid on-disk data structures directly involved, so
follow the usual debugging vs. non-debugging approach.

Fix two issues with lockmgr(9) LK_CAN_SHARE() test, which determines
whether the shared request for already shared-locked lock could be
granted. Both problems result in the exclusive locker starvation.
The concurrent exclusive request is indicated by either
LK_EXCLUSIVE_WAITERS or LK_EXCLUSIVE_SPINNERS flags. The reverse
condition, i.e. no exclusive waiters, must check that both flags are
cleared.
Add a flag LK_NODDLKTREAT for shared lock request to indicate that
current thread guarantees that it does not own the lock in shared
mode. This turns back the exclusive lock starvation avoidance code;
see man page update for detailed description.
Use LK_NODDLKTREAT when doing lookup(9).

In agp(4) avoid the need to flush all cpu caches with wbinvd between
updating the GTT and flushing the AGP TLB by storing the GTT in
write-combining memory.
On x86 flushing the AGP TLB is done by an I/O operation or a store to a
MMIO register in uncacheable memory. Both cases imply that WC buffers are
flushed so no memory barriers are needed.
On powerpc there is no WC memory type. It maps to uncacheable memory and
two stores to uncacheable memory, such as to the GTT and then to an MMIO
register, are strongly ordered, so no memory barriers are needed either.
Get rid of the postrandom script. It was born in a time when the
random script ran before filesystems were mounted, which is no
longer the case.
In random_start(), immediately delete each file that is fed into
/dev/random, and recreate the default entropy file immediately
after reading and deleting it. The logic used in random_stop()
to determine which file to write to should probably be factored
out and used here as well.
add an rc.d script to automatically grow the specified FS... It has
been tested on both MBR and GPT... It won't be enabled until you add

Fix the two affected tests by creating an auxiliary directory to use for

upstream to take a look at this.)
