b15a09c05e Add an ioctl to suspend a virtual machine (VM_SUSPEND). The ioctl can be called
from any context i.e., it is not required to be called from a vcpu thread. The
ioctl simply sets a state variable 'vm->suspend' to '1' and returns.

The vcpus inspect 'vm->suspend' in the run loop and if it is set to '1' the
vcpu breaks out of the loop with a reason of 'VM_EXITCODE_SUSPENDED'. The
suspend handler waits until all 'vm->active_cpus' have transitioned to
'vm->suspended_cpus' before returning to userspace.

743c072a09 Correct ARP update handling when the routes for network interfaces are
restricted to a single FIB in a multifib system.

Restricting an interface's routes to the FIB to which it is assigned (by
setting net.add_addr_allfibs=0) causes ARP updates to fail with "arpresolve:
can't allocate llinfo for x.x.x.x".  This is due to the ARP update code hard
coding it's lookup for existing routing entries to FIB 0.

sys/netinet/in.c:
	When dealing with RTM_ADD (add route) requests for an interface, use
	the interface's assigned FIB instead of the default (FIB 0).

sys/netinet/if_ether.c:
	In arpresolve(), enhance error message generated when an
	lla_lookup() fails so that the interface causing the error is
	visible in logs.

tests/sys/netinet/fibs_test.sh
	Clear ATF expected error.

3ad1a09169 Rather than require a makeoptions DEBUG to get debug correct,
add it in kern.mk, but only if we're using clang. While this
option is supported by both clang and gcc, in the future there
may be changes to clang which change the defaults that require
a tweak to build our kernel such that other tools in our tree
will work. Set a good example by forcing -gdwarf-2 only for
clang builds, and only if the user hasn't specified another
dwarf level already. Update UPDATING to reflect the changed
state of affairs. This also keeps us from having to update
all the ARM kernels to add this, and also keeps us from
in the future having to update all the MIPS kernels and is
one less place the user will have to know to do something
special for clang and one less thing developers will need
to do when moving an architecture to clang.

73279d4113 Add a new ARM TARGET_ARCH, armv6hf. This is considered experimental.
This targets the existing ARMv6 and ARMv7 SoCs that contain a VFP unit.
This is an optional coprocessors may not be present in all devices, however
it appears to be in all current SoCs we support.

armv6hf targets the VFP variant of the ARM EABI and our copy of gcc is too
old to support this. Because of this there are a number of WITH/WITHOUT
options that are unsupported and must be left as the default value. The
options and their required value are:
 * WITH_ARM_EABI
 * WITHOUT_GCC
 * WITHOUT_GNUCXX

In addition, without an external toolchain, the following need to be left
as their default:
 * WITH_CLANG
 * WITH_CLANG_IS_CC

As there is a different method of passing float and double values to
functions the ABI is incompatible with existing armv6 binaries. To use
this a full rebuild of world is required. Because no floating point values
are passed into the kernel an armv6 kernel with VFP enabled will work with
an armv6hf userland and vice versa.

44f1c91610 Rename global cnt to vm_cnt to avoid shadowing.
To reduce the diff struct pcu.cnt field was not renamed, so
PCPU_OP(cnt.field) is still used. pc_cnt and pcpu are also used in
kvm(3) and vmstat(8). The goal was to not affect externally used KPI.

Bump __FreeBSD_version_ in case some out-of-tree module/code relies on the
the global cnt variable.

52f3c44efe Fix two issues with /dev/mem access on amd64, both causing kernel page
faults.

First, for accesses to direct map region should check for the limit by
which direct map is instantiated.

Second, for accesses to the kernel map, success returned from the
kernacc(9) does not guarantee that consequent attempt to read or write
to the checked address succeed, since other thread might invalidate
the address meantime.  Add a new thread private flag TDP_DEVMEMIO,
which instructs vm_fault() to return error when fault happens on the
MAP_ENTRY_NOFAULT entry, instead of panicing.  The trap handler would
then see a page fault from access, and recover in normal way, making
/dev/mem access safer.

Remove GIANT_REQUIRED from the amd64 memrw(), since it is not needed
and having Giant locked does not solve issues for amd64.

Note that at least the second issue exists on other architectures, and
requires similar patching for md code.

This appears to fix a strange condition with X on 32-bit PowerBooks I observed,
caused by one of these bits getting set in the mcontext, but not set in the
thread, which may be a symptom of another problem, more difficult to diagnose.
Since these bits aren't exported anyway, this change makes it more explicit that
the bits aren't MSR-related in SRR1.

These are needed to diagnose TX hangs that I and hiren are seeing.
Without it, the only way we'll see debugging is by having ATH_DEBUG_SW_TX
enabled and that is going to be very, very spammy.

ATH_DEBUG_RESET is fine; it's only going to be done during stuck beacon
situations in AP mode.

Whilst I'm here, and now that it's behind debugging, let's just disable
the "print only one" conditional.  I'll eventually make it more tunable.
