Commit 49c894ddce introduced an issue that prevented pseries boot,
when hugepages were not available to the guest. Now large page
info must be available before moea64_install is called, so this change
moves the code that scans large page sizes before the call.

The KCSAN_ENABLED variable is non-empty when the kernel is being built
with KCSAN. This allows us to disable modules that are known to be
broken.
There was a bug where we would check if it was defined. As this is
always the case the KCSAN_ENABLED variable would be set when building
modules so we would never build such a module. Fix this by checking
if the value is empty before passing it on to the module stage.
This doesn't affect how modules are built as the CFLAGS passed to
modules has the correct check.

DBG2 ACPI table description [1] specifies three subtypes
related to 16550 UART:
0x0 - 16550 compatible
0x1 - 16550 subset
0x12 - 16550 compatible with parameters defined in Generic Address Structure (GAS)
It turned out however, that the Windows OS treats 0x0 subtype as
legacy x86 UART with 8-bit access. ARM SoCs can use types 0x1 (16550 with
fixed mmio32 access) or 0x12 (16550 with fully respected GAS contents).
Switch Marvell SoCs ACPI UART subtype to 0x1 - thanks to that the same firmware
can run properly with UART output in FreeBSD, Windows 10, Linux and ESXI
hypervisor. Tests showed the older firmware versions that use 0x0
UART subtype in SPCR table continue to display output properly.

Instead of using the default hostuuid, just treat it as a failure and

It also makes the gcc6 build happy.
There are several NFSv4.1/4.2 server operation functions which
have unneeded checks for the NFSv4 root being set up.
The checks are not needed because the operations always follow
a Sequence operation, which performs the check.
This patch deletes these checks, simplifying the code so
that a future patch that fixes the checks to conform with

The current WPA build assumes a flat namespace. However the latest sources
from w1.fi now have a duplicate config.c, in two separate subdirectories.
The flat namespace will overwrite config.o with the output from the most
recently modified config.c, of which there are two of them.
This commit resolves this problem by building each component in
wpa's src subdirectory tree into its own .a archive, just as the w1.fi
upstream build as used by the port does. The advantages of this approach
are:
1. Duplicate source file names, i.e. config.c in the wpa_supplicant
direcory and another config.c in src/utils in the next wpa
will result in both compiles writing to the same .o file.
2. This restructure simplifies maintanence. A develper needs only to add
new files as identified by git status in the vendor branch to the
appropriate Makefile within the usr.sbin/wpa tree. This also reduces
time required to prepare a new import and should reduce error.
3. The new wpa build structure more closely represents the build as
performed by the upstream tarball.
This is in preparation for the next wpa update from w1.fi.

When PTI is enabled, we may have been on the trampoline stack when iret
faults. So, we have to switch back to the regular stack before
re-entering trap().
trap() has the somewhat strange behaviour of re-enabling interrupts when
handling certain kernel-mode execeptions. In particular, it was doing
this for exceptions raised during execution of iret. When switching
away from the trampoline stack, however, the thread must not be migrated
to a different CPU. Fix the problem by simply leaving interrupts
disabled during the window.
