24e8823ef5 Adjust function definition in isa's pnp.c to avoid clang 15 warning
With clang 15, the following -Werror warning is produced:

    sys/isa/pnp.c:118:24: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
    pnp_send_initiation_key()
                           ^
                            void

This is because pnp_send_initiation_key() is declared with a (void)
argument list, but defined with an empty argument list. Make the
definition match the declaration.

02a226ac34 Suppress possible unused variable warning for icl_soft.c
With clang 15, the following -Werror warning is produced on i386:

    sys/dev/iscsi//icl_soft.c:1277:6: error: variable 'i' set but not used [-Werror,-Wunused-but-set-variable]
            int i;
                ^

The 'i' variable is used later in the icl_soft_conn_pdu_get_bio()
function, via the PHYS_TO_DMAP() macro. However, on i386 and some other
architectures, this macro is defined to panic immediately, so in those
cases, 'i' is indeed not used. Suppress the warning by marking 'i' as
unused.

4eadbef924 vmm: emulate INVD by ignoring it
On physical systems the ram isn't initialized on boot. So, coreboot uses
the cache as ram in this boot phase. When exiting cache as ram, coreboot
calls INVD for making the cache consistent.

In a virtual environment ram is always initialized and the cache is
always consistent. So, we can safely ignore this call.

82042465c3 icmp6: Improve validation of PMTU
Currently we accept any pmtu between IPV6_MMTU(1280B) and the link mtu.
In some network topologies could allow a bad actor to perform a DOS attack.
Contrary to IPv4 in IPv6 oversized packets are dropped, and a ICMP
PACKET_TOO_BIG message is sent back to the sender.
After receiving an ICMPv6 packet with pmtu bigger than the
current one the victim will start sending frames that will be dropped
a router with reduced MTU.
Although it will eventually receive another message with correct pmtu,
an attacker can still just inject their spoofed packets frequently
enough to overwrite the correct value.
This issue is described in detail in RFC8201, section 6.
Fix this by checking the current pmtu, and accepting the new one only
if it's smaller.

9f3aa538e3 sbin/md5.c: fix -q -c for BSD style versions
The BSD style commands (with names not ending in "sum") ignored the -c
options and the passed digest value when invoked with -q.

The man page stated that -q causes only the calculated digest to be
printed, but did not consider the case of both the -q and -c being
used in combination.

Since there is no warning that -c will be ignored when the -q option
is used, users night (and did) expect that the exit code would reflect
the matching of the calculated digest and the argument passed with -c.

This update implements and documents this expected behavior.

a79731b945 Fix unused variable warning in sfxge's ef10_tx.c
With clang 15, the following -Werror warning is produced:

    sys/dev/sfxge/common/ef10_tx.c:345:15: error: variable 'eqp' set but not used [-Werror,-Wunused-but-set-variable]
            efx_qword_t *eqp;
                         ^

The 'eqp' variable is passed as an argument to the EFSYS_BAR_WC_WRITEQ()
macro, but currently this macro ignores the argument, similar to its
other _esbp argument. Silence the warning by casting the _eqp argument
to void in the macro.

it. Remove the variable since it no longer serves any purpose.
